These videos are a gold mine of information. They allow home owners to resolve simple issues (and better understand their home) without having a technician charge $80-$125 to flip a switch. Saves embarrassment also LOL. Thank you sharing these videos, I really could have used them earlier in my life!

A month ago , my neighbor's AC unit would not engage. He called the HVAC people to come. They came, investigated (?) and blamed the thermostat as being defective ( almost new Honeywell WIFI version). I gave him my "old" battery thermostat (replaced with an ECOBEE by me, after watching your videos). The replacement didn't work either. I went to the outdoor unit and found no 24V signal, and then to the control board and determined ( per your videos) it was still functional. I pulled the 3A fuse and , voila, it had blown. Put in my spare and the AC fired right up ! What had happened is that they had a painter in and he removed the thermostat without shutting off the power. The fuse saved the board. And, yes, I have been guilty of accidentally flipping the furnace switch off , but now I always check that first !! Thanks for all you do.

Jay, I finally repaired my HVAC, I'm so happy. I followed your videos and it helped entirely. I'll share with you my experience as it was an entire adventure: First the AC unit was not cooling. When checked outside the fan was not getting any signal to be turned on, so I thought it was just a change needed in the capacitor. I went to home depot on a friday 7pm and I got extremely pissed becaus they don't have anything in physical for hvac, and online takes days to deliver. So we gave up and went somewhere else to sleep for the night because it was so hot. Next day in the morning I looked for a hvac parts store and found one, and bought the capacitor. I followed your videos, I installed it, and it "worked". The fan was now not spinning! I took the motor out and it was so jammed and rusted, rushed back to the hvac store to get a new motor, they gave me a "universal" motor with 4 cables (my old unit had 3 cables). Followed your videos, cut the brown and white as you instructed, reconnected everything (sounds easy but took hours to even pull the fan out of the motor it was extremely stuck). Even your technique of using sand paper worked beautifully. now with new capacitor and condenser fan motor it was the moment of truth. I turned on and it wasn't spinning!! I thought I was lost because I thought I had done something wrong and was about to give up and just call a techinician. I checked more of your videos and found how to bypass the termostat by using the contactor. I pressed the contactor and it worked! the fan started spinning and immediately started cooling, BUT the contactor wasn't staying plunged. so now I checked your contactor video, had to run again to the hvac store, got a new contactor, followed the instructions again reconnected the new contactor and BAM everything was working perfectly!! I was surprised how everything worked and how by just looking at your videos we did it! I should say that, a technician did really came to our place before, but he was charging us 2-2.5k because he said the compressor was old and not working and is better to get a new one. But that sounded sketchy AF. Anyway, I'm extremely happy everything worked and I now feel confident to engage into more repairs myself Thanks!! PD: I spent 123 dollars in total.

I think I owe you thousands of dollars lol.I mean because of your honest videos I have saved a lot of money. Many thanks.

You just saved me my friend!!!! Honeywell WIFI thermostat was shut off and I never realized it, no power to it. I watched through your video and went and checked the circuit breaker, and I was on for the furnace. I then went and looked at my furnace switch down where my HVAC unit is, and it was shut off! I just had someone in my house doing a termite inspection, and he must have turned it off in his poking around! Thanks for saving us!

It worked! I had no idea I had accidentally switched the furnace off moving stuff around in the basement. Thanks so much!

11. Didn't pay your electric bill.

A great presentation,self explanatory and very easy for DIYs try troubleshoot!!! Before watching this video, I already tried out a few things of my own,will follow up on this video,hopefuly I am able to bring my thermo to life.. Tnx a lot.

Thank you for this video. Back to detective work. Much needed. 😊

Another helpful video Jay, keep ‘em coming. Stay well my friend . 👍🙏

Great tutorial keep the videos rolling my friend 👍

Very Helpful thanks Jay

Your a great teacher !!!!!

Support from this HVAC Guy 👏 ❤

Those bad jokes are probably one of my favorite parts of these videos.

Great Video. Thank you for sharing

Excellent, excellent, excellent!!! Thanks!

This is incredible. Thank you.

Very helpful tips, that's why I subscribed!!!

I have an Ecobee thermostat which went blank. I watched this video and also a few more videos about Ecobee. I just pulled out the unit and plugged it back in. Voila ! It rebooted and working !

Thank you Jay another awesome video🙏

Thanks for good info

Thank you. Your video helped me solve my problem

Really helpful saved my family money Thanks

Thanks a lot for your great video and helpful info

Excellent Video, Thank You.

Another great 1 👍👍👍

this is SO helpful. Thank you

Excellent !!!

Excellent. Thanks

Good stuff, thank you

You are very good ❤

Great explanation of all 10 issues. I have a NEST thermostat. Many experienced HVAC technicians that post videos, don’t like/hate nest. I love mine to adjust temperatures from my bed before I get up or remotely (outside the home). I think it also saves $$. Occasionally (once every couple weeks) the remote feature on the App DOESN’T adjust the temperature or fan remotely. I go old school and walk to the stadt to manually adjust. Common is connected. I THINK, this happens when an energy saver feature is activated. Minor inconvenience either way. U have any thoughts?

👍 love your videos

Thanks for posting this clip..

Thank You my man

Well spoken

Regarding Item #9 - what if the reading is i.e. 70V? I have a 30 year old Bryant Evolution Furnace and Heat Pump and one of their digital/analog thermostats. Just last week I tired to replace the Bryant thermostat with a Honeywell 24V thermostat - but it did not work as it won't if the voltages it receives are higher than 28V. Is there a switch on the furnace to limit the voltage to the thermostat? Also BTW, my system only has metal (cleanable) filters (including electrostatic ones), and I wanted your comments on those types of filters as your filter videos just discussed the paper ones.

Thanks!

exelent video

Excellent video what’s strange about mine is ½ screen is dim. Inside temp is left hand reads correctly 79f. Set system temp I manually and do not use timer to schedule temperature I just use it for manual up-and-down leave if it’s midday, I’m gonna set it at like 80 or 82 but generally, I keep it between 76 and 78. The right hand side it’s like part of the numbers you can read the first digit you read that it has sent it to 77 or 78 where is the eight or seven part of it halfway disappeared

Ты лучший!

I want to ask you, are there special types of television for places near the sea? I suffer from a problem of humidity when the TV is left on for a long time without working in a house that I do not go to in the summer

one more question... Can control board in front case go bad? When I put new face on, solved the problem. Left old base on.

Thanks❤

Accumulated dust debris clogged the drain and switched open the overflow safety switch, and turned off the thermostat. I pushed out the debris and manually reset the drain switch. Thermostat automatically reset itself. It’s been 95 F when this happened. Thank you for the valuable information.

What size ac do u recommend for a 1000 square foot house? Thank you

You rock, Thanks! Loved the joke BTW

There is another way to verify if the problem is the thermsotat itself. Unplug the furnace or turn off the power switch first amd foremost. Then remove the thermostat. If summer, take cooling wire (normally yellow) and power wire (notmally red) and twist them together. You need to make sure that they are the correct wires by looking at the wires on the board. If in winter, use power wire sgin but this time you want the heating wire (normally white). Again verify you have the two corrdct wires. Then re-apply power. If ot cycles through correctly, then the problem is the thermostat. I have used this many times in the field and in my own home

Hay what do you recommend if you have a refrigerant leak in your thermos but you don’t want to replace it

Great job what about a bad transformer thanks for the viedo

Jay - So sad to see the condition of areas on Maui. I forget which island you guys ended up getting a house, but hope you guys and your brother and sister and all are okay.🤞 Take care. -Jeff

Hope you and your family and friends are safe ; I believe you had settled in Maui HI.

What’s the “Orange colored wire” for. I have the Honeywell Home thermostat and I connected the blue wire to the red power source and it all appears to be working fine. Just curious as to what to do with that orange wire.

Adding #11- check the corrosion on the spring connector to the batteries. I noticed mine were corroded so I used a Q-tip with baking soda and water to gently clean the corroded springs, keeping everything dry around it, then re-insert of the batteries. Display came on and everything working perfectly.

Hey Jay I have a question could you make a video of why when you turn your air conditioner on it doesn’t blow any cold air it only blows hot air. The reason why I asked you if you could make a video on this topic is because I ran into this problem I would really appreciate it if you could make a video about why hot air blows when the air conditioner is on. You rock brother.

0utstanding!👌

I came for the DIY advice, I stayed for the bad jokes. 👍🏻

WORD TV! I have a thermostat working without C wire, want to replace it do to the set point buttons don’t work. I am replace it for Honeywell ST76, I have the C wire but when I do the right connections do not power on. I get 23 volts from the furnace and by the thermostat, I thought is a bad thermostat and bought Honeywell Home RTH9580WF01 and have the same result. For now I am using my old thermostat so is none of the advises you said, please can you help me?

And also the LCD screen is just shot. Common with Honeywell controllers. It takes a hard knock with a fingernail to wait it up!

Hello 👋 🫂 my number one good buddy Jay 👍 good to see you I was just thinking about you earlier this morning wondering how you all were doing. It's been a rough time here lately my aunt passed away this morning, she is the aunt that gave me the jaguar..she got sick and went to the hospital and her daughter my cousin called me yesterday and said the Dr called her to come to the hospital as soon as possible because she wasn't expected to make it through the day yesterday so after she told me I drove to the hospital to see her and she was in and out of conscious but I got to talk to her and see her. She went into sepsis shock and her organs were shutting down yesterday but my cousin called me and said that she went very peaceful..take care buddy I love you and your family Jay. Take care and God bless you and your family. Oh almost forgot tell everyone I said hello 👋

20gauge and lower wire is especially troublesome very brittle and hard to notice

My thermostat backlight works sometimes, other times not. Any thoughts?

I have ecobee thermostat went dark, no 24v(it is 24v ac or 24v Dc?)

Nice job

I get 28 volts between red and blue wire. My thermostat comes on and within 10-15 minutes powers downs and restarts again. On and off. I have replaced the thermostat Honeywell T9580 WiFi for a brand new one and still got the same issue. Fuse is good, wires are connected. Could it be the transformer on its way out.? Spiking or dropping voltage causing the thermostat to come on and off.? Thx

Greetings . What the common wire and C spot is not being used . The blue wire is rolled back and the common space is not being used . Should hook it up ?

Hi. The screen on my thermostat is blank. I replaced batteries, nothing. A couple days was back on. Now blank again…but, if I press the temperature up, it comes on (not the screen, the furnace). Also, if I turn fan on it comes on. Any ideas 💡. Thanks so much.

Overflow cut-off switch. Should be #1.

FOR ME it was as simple as the power switch on the lower left side of the furnace. got a flash light gave it a shine found that switch in 5 seconds or less...ty

Both of my Honeywell tstats have started going blank when the A/C is off. They are still working because you can hear them click, the A/C comes on and both tstats come on. As soon as the A/C goes off, they go blank again. The A/C never runs long enough to drop the temperature but I am pretty sure I hear the Tstat click like it is telling the unit to shut off. All filters changed within the past couple of months and this just started in the past week.

Let me tell you what is happening in my house now, in case you can use the topic for a video. Topic: very bad smell in kitchen. Smells like sewage. Concern: sewage backing up? Something broken? Action: I looked at both bathrooms, smelled the drains, checked plumbing below sinks for leaks. One toilet is not in use for now (leaky fill valve), so I put water in the bowl to fill the p-trap, even though there's no smell. Smell appeared to be coming from kitchen drain. No leak underneath. I called the town, they came out to check the outside clean out part, told me "their end is clear and my water is running fine through the system. Get a plumber." No money for plumber. Didn't want to do this to my drain, but I felt stuck, so I poured one pot boiling water into drain. I mixed baking soda and vinegar, put that in drain, waited 10 minutes, poured another pot of boiling water into drain. Result: smell still in kitchen. Definitely not from sink drain. I was worried that maybe sewer line was broken under my house (I live on a slab, no basement). Can you imagine the jack hammering inside my home, and the massive cost? Feeling a bit desperate. Next action: KZfaq searching. Suffice it to say that I found a possible answer, so much better than broken line. I was shocked, never heard this before: the drip tray under the refrigerator can be the source of the smell. So I sniffed around again, and this appears to be a strong possibility. I should say that the fridge has not been functioning properly for years, not keeping cold enough, and the freezer part doesn't work. I read about how to clean the drip tray. Fridge drip trays are bolted to the bottom of the fridge, they can't just be pulled out and cleaned. I I can not safely tip the fridge myself. Only had one person to call to help with that, but he just passed away. Plan of action: Since I can't get to the tray, and since the fridge hasn't worked right for a long time, it might be time to throw the fridge out. I really really love that fridge. What a shame. I can't go without a fridge because I keep insulin in there, I will have to get another one, even if it's just a mini fridge. New full size fridges are very expensive. Bonus: I just had a discussion with my endocrinologist about how can my A1c be out of control if I'm doing everything right? Possible answer: fridge isn't cold enough to keep my insulin safe. All this time my health has been deteriorating, and this could be one of the reasons. My insulin is rendered ineffective by improper storage temperature. How crazy is this. Perhaps now the doctor will ask her other patients if their fridges are working properly, and suggest that they get fridge thermometers to keep watch over the air temp. Summation: Don't panic. Calmly find source of smell, using free or inexpensive methods. Amazingly, fridge drip tray can be source of sewage smell, so don't skip that possibility. Cheap fix if you have reliable help to safely tip the fridge to clean drip dray, or if you can afford a plumber to do it for you. After cleaning, leave it off for a few hours before turning back on. It's possible this procedure could damage the fridge. Protect yourself - don't let anyone talk you into massive expense replacing sewer lines without proof that that is the cause. It's probably something simple. Don't let the distress over that over smell cause you to act in haste or desperation. This is very long-winded, but it might be worth it. Save people from desperate, unnecessary expenses. Save some diabetic lives. Thanks for listening, Jay. Love your channel. Best to you and your family!

My thermostat goes blank most of the time, and comes back on occasionally. Any ideas on what to do?? Thanks I replaced the batteries, same deal.

request your learned opinion: I have multiple thermostats that always seem to have problems with the temp up or down buttons. Is there anything to help or fix this inconsistent depressing of the buttons . The rest of furnace is fine . Again it's just the stubborn up and down temp buttons. batteries are new. depressing button contact-- are not working properly. Rather than buying new replacement thermostats , ( 3 x 60 - 100 dollars ) I would seek a fix. Am I delusional ? Just asking your opinion I have one of the old round simple thermostats that always works *technology*

Where is the control board located on the attic unit?

2:54 MAGIC! HE'S A WITCH!

My ac unit outside seems to be working but when I turn on the ac on my board it makes 3 clicking noises and nothing happens and I noticed the pipe was starting to freeze up.

#11 Thermostats like the one shown in video can be flakey in its connection between the two halves. Pulling off and replacing, sometimes wiggling it after checking the batteries, makes it work. Sheesh.

I flipped my breaker on and off, prior to that it was on and working fine. I had to flip them for another reason. But now that Honeywell thermostat doesn’t show anything… how can I get it to turn back on?

can I clear out the plugged drain myself? If so how

Why do I have to take the front of the thermostat off and snap it back on to make the heater turn on? This happens in the evenings and through the night.

I hate when the power flicks on and off. That is so bad for your a/c system

Help please! This happened to my thermostat, and when HVAC guy came out, he said the thermostat wire needed replaced, so I replaced it. Now I still can't get my unit to come on by itself, what could be wrong? Please help I'm dying without AC, I live in Alabama and it's 100 degrees outside! I've been without AC for going on seven days, please help me

What about a blown transformer?

The 3 Amp fuse shot. Just replace it for under $2

How to cancel the schedule

Transformer reason 11

I totally forgot about the light switch. I'm gonna tell my wife I'm a genius and also not point fingers at the same time

the thermostat keeps turning off and on (wifi honeywell ) But not affecting the furnace, it's running fine

Step down transformer is bad. That was my problem.

Great informative vid Jay ... A lot of people are working from home these days and Burglars gotta eat too Aloha my friend

Thermostats dont have batteries anymore

👍💯

❤👍🐺

I am way ahead the current time , smarter than the millennial generation , I AM USING A MANUAL ONE 👍 trouble free and no batteries replacement required ！
