I am so caught up watching how you troubleshoot the problems. From obvious to the inobvious! Awsome work!

Great work Ted. Charge looks good to me as well. Thanks for the tip as well for the furnace

I like my straight cool with 10kw heater. 15 years old and only replaced the Dual capacitor about 3 years ago. And did a coil clean. still going strong.

Love ur accent first. Love ur yellow truck second i drive one for the last 10 yrs.....in the field for 30. And 3rd ur troubleshooting skills are priceless. Be blessed Cool Guy😀

You have solved the issue for me, as my new S9V2 (February) was giving me this same problem when I turned on Cooling for the season, and the installer did not believe me that there was an issue. I had to set the Menu to 3 tons for my 1.5 ton unit to get the proper CFMs, as indeed it was running on low speed. This meant no lower speed for the fan at 50% setting. After 3 weeks of waiting and having been told that nothing was wrong, and that I should contact Trane directly, I searched for info and found your video. The installer had indeed forgotten the jumper. He did not and would not come to my home to see what might be wrong. Thanks so much.

Nice concise video, also very good explanation of 1 stage cool & 2-stage heat.

Good video Ted. Thank you for all the recommendations of what equipment you recommend pairing together.

Completely agree on two stage cooling for low seer resi equipment. Only really useful running two equal zones. Dehu is best done with dedicated equipment or solving other problems.

I just put one of these in yesterday longest part was programming the board for while checking static pressure. I love the height of this new furnace but thats about it.

I like two stage more as a reserved cooling capacity on hot days than for dehumidification. In other words size it right in first stage and have the second stage be oversized for the space to maintain the setpoint even on the hottest days. Also use the Y Low terminal and set the CFM to 450. Using the BK as Trane states causes too much air flow in first stage keeping the humidity around 50% VS 45 which is more comfortable.

Thank u. Made my day. 3 previous trips to my customer.

Y1 or Y2 In my experience there is a limit for cfm/fan speed on each of these, but not sure how this particular unit works. Depending on max from each and size of outdoor unit, or dual stage, you connect to the appropriate terminal(s).

Thanks for the vid!

You don’t need to jump it. Move the wire to Y1. Go into the menu and check the settings.

Hi I like your video

Love the channel. It is my go to before I call and bug you in person. Here trying to figure out how to increase fan speed on a Trane 80% , in fan only it is running on very low. Works fine in heat and cool. It is Pepe's house. In your old neighborhood. May be calling you..

That's good for cool. How to make the blower speed run high on heat?

Good one Ted, thanks!

Only needs Y1 with a single stage thermostat.

Not sure you are right. It should connect to Y2 in furnace, otherwise the blower always run at slow speed (y1). Maybe different machines have different setting?

Looks good. Grommet missing on the right side of where float switch is going in. Just busting your chops bud. Lol

Where can I buy the pressure gauges you use?

What could be causing my blower speed to fluctuate a lot but mostly run at very low speed during cooling season? This is a problem I’ve been having during a recent spell of hot weather, no issues otherwise since install 7 years ago. Usually turning the system from cool to off for several hours fixes the problem and then it’ll work fine again for a day or two. If I leave the system off but the fan on, it seems to blow at the expected medium speed.

There is a good use @ reasonable cost for two stage cooling. When you have a two or three zone system this can be very efficient and affective.

Hey Ted, in the upper left-hand corner of that board there's a little square with an "FP" in it at the (3:00 min. mark) and it says "flame current" right above there. It looks like there are 2 little solder pin positions there. Is that where you take is that where you take the uA for the flame sensor reading at on that board?

Correct .6 oz per foot. Itchy Mee-shee has a diff charge gang. Read the book cause the many circuits may change what we do.

Any idea how to make this unit run dehum mode? Can i just get hunidistat and working?

One question and what can we check if the blower ecm motor not stop working????

How do I test if my VFD it’s running at full speed? I know by fact that a degraded fan signal that results in the fan speed being lower that the board is requesting. For example, at fan only 50% fan signal should be 30 HZ on the VFD. At 100% fan signal (full cooling) the VFD should be running 60 hz. If you see something different, the board may need to be replaced.

so that was your retrofits did the installers forget to RTFM? lol shouldn't the t-stat and condenser be on Y1 with jumper remaining from Y1 to O, nothing on Y2, then set any blower ramp delays through the board menu.

sir: my heat pump package ECM blower will only work when its fan is set to ON. In auto, it stops

All this computer sh#@t makes me sick . But at the same time we Maint and HVAC guys have to understand how this stuff works. Great Video Ted 👍👍

the installers didnt do anything but open the valves and go...the charge is right on due to short line set.

Anti DIY, if you were to replace a 3 ton single speed 13 SEER heat pump, ICP Heil, what today would you go with for best longevity and reasonably high SEER 16-20? Even considering a mini split cassettes with multi zones. Thx~

I'm with on the single , let the thing run cool the house down , shut off and save electrical cost , if u are that concerned about humidity ,they make dehumidifiers.

Here again!

I thought you just wire to y1 and set in the control board that it is single stage, the outdoor tonnage and the cfm per ton.

dehumidification mode? yes yes.. its a residential area so on a turn invert the speed limit number.. 15 has become 51🏡🚘🏎 👍 airflow is the 1st place to start. clean coils & blower wheel collapsed vent line

Why wouldn’t you leave a note on a panel when it was put in and initials of the installer or on a sticker with your company info

So are you saying either get a single stage or go to a variable 18-20 seer unit? Isn't that a huge price difference? So 2stage to you has no real benefit over single? I ask because I'm replacing 2.5 ton 14 seer single stage unit soon sq 1,450 ft home. I think i would have to move up to a 3 ton unit to get any kind variable stage units.

Ok

Why do so many builders put the dryer vent right next to the a/c condenser?

Please speak up when you are recording yourself. When you mumble we can’t hear you a lot of us are sitting in our trucks on our downtime trying to learn more but there’s road noise around us. But thank you I appreciate your content.

2 stage beats single stage all the time, 2 stage cooling saves more electricity. Gas is cheap....

So what happened when you were a kid ? You can't just edit that part out you know second 15 bro.

Hey answer me right now
