I had never seen an outside unit like that. Here in AZ they're all inside. I learned to fix mine thanks to KZfaqrs such as yourself. Thank you sir!

I understand this is a residential based instructional video, but most RTU's are commercial based with an economizer installed. You should release a video on economizer troubleshooting and operation as well. I appreciate your videos and instructional content. They are very well thought out and presented. I myself am a commercial/ industrial service technician, who enjoys watching and learning. You don't see many RTU's in a residential setting. Do you ever cover the more typical commercial equipment? Thanks for what you do for the trade. Helping younger techs become better more proficient individuals

I'll watch later today. Did you mention not having a way to vent an old expansion tank? Pressure keeps relief valve off the furnace leaking.

@mackenziegray2090 2 жыл бұрын

You mean expansion compression tank? The older styles, sometimes you have to isolate and drain them. Over time they will completely fill with water and have to drain them once in awhile.

Our gas valve seems to freeze. Very little gas output in the cold such that the burners do not ignite and they system cycles off

Can somebody please recommend a good heating troubleshooting field guide?

@mikem.2078 2 жыл бұрын

My problem is that the furnace works, for only like 20 mins or so. It will shoot up to the temp I program on the wall thermostat (say 73F), reach that temp, shut off, and NOT come back on later so the apartment gets super cold, and never come back on. Now there is one trick -- at bottom of furnace is a large red button, I push that red button all the way in, and SOMEtimes the furnace will turn back on for another 20 mins, but sometimes not. On rare occasions the furnace will function for 3 or even 4 hours, but not often, and wouldn't you know it, it usually shuts off when I get in bed. Note: I already cleaned the furnace flame sensor one time with the brillo end of a dish pad, so that's probably ruled out. (Furnace brand is Williams, model 2509622).

@nsudatta-roy8154 2 жыл бұрын

You may have a faulty sensor that is designed to open when a "condition" happens or not happening. The flame sensor is no exception. I haven't looked at your schematic, but consider looking at what other components are wired in series with your flame sensor. Edit: you may not wanna keep pressing that red button.

The inducer motor runs even when the thermostat shuts off and the system itself isn't igniting. I had to cut the breaker off to stop it from running constantly! My unit is 3 years old and I really don't know what to do!

@allenshakhmalian5746 Жыл бұрын

What if the exact same unit heat goes on and off ? I checked the burner , ignition switch works but burner doesn’t go on ( no flame ) ? Some days it works but some days it doesn’t:(

@user-fs2of1dx9u 7 ай бұрын

Red light on board goes out when unit calls for heat. Comes on, Inducer motor tries to start, shuts right off. Keeps trying. Red light goes on and off during this. Any ideas? Bad transformer?

@breyization 2 жыл бұрын

A guy I use to work with called me about his furnace it would go through the sequence of operation fine but after glow plug no ignition . He said the glow plug has a white spot on the glower I told him he needed a new one. He tried to jump it out called me back said it sparked on him and he had to reset the breaker, now his inducer comes on for a short time like a minute then stops and the fan come on. Any idea what he may have messed up, I'm thinking the pressure switch is acting up

@Alex-jo2oi Жыл бұрын

Easy way to test pressure switch is putting meter leads on both terminals of the switch. And taking the tubing to your mouth and pulling in like you would a straw. It’ll close the contacts and if it’s malfunctioning it won’t close contacts.

And? Lol. As an automotive technician and now being an HVAC tech sometimes I wear gloves sometimes I don't. You're not going to wear them in every instance. Actually you really don't have to. Only time I really wear gloves is if I'm dealing with sheet metal or it's cold outside.
