Question about Ruud UBHC Air Conditioner

1 Answer

Air Conditioner not working

I was weed eating yesterday and I got tangled in what looked to be the wires that go to the thermostat, well needless to say my AC shut down and once I hooked the wires that I cut back up still a no go, I checked under the house and followed the wires all the up and to the thermostat and it is fine, there are actually spots where it is zip tied off to prevent to much tension, there is what looks to be a momentary test button on the side of the AC under the electrical panel and when I press it the fan kicks on, but like I said it is momentary. I also took apart my thermostat to see if anything was fried and it looked OK too. I deal with car electronics all day (i know not completely the same but) I know what a bad electrical board looks like. Either way, all the breakers are good and are not popped so I don't know where else to look.

Check on the board and see if the 3amp fuse is blown,if you do not have
a fuse in this board, then check for 24volts between R and C, if you do
not have voltage there your transformer is blown, it will also have a bad
burnt smell if it happened

3 amp fuse blows when ac is switched on. Heater works fine.


There is a short in the low voltage wires somewhere for sure. The most common place is the low voltage on the outside unit, sometimes animals chew through them or they get cut with a weed eater. Just my experience. You basically have to trace it back all the way to the thermostat and heater. The only other thing is the contactor

Son weed eating and hit wire outside now have no eletric to thermostate and wont come on wire is not broke into


The transformer may be shot. Place the fan switch on the thermostat from auto to run. The indoor fan should come on. If it doesn't then the transformer is probably bad. You can check for power on the transformer primary and then the secondary. If you have power on the primary and not on the secondary then it is no good either.

Rheem outside a/c fan won't turn off


I would probably start at the thermostat and see if 24 volts is continued to be applied to the yellow wire which calls for unit activity even though you have called this off. Shorting the cool (yellow) wire to the return (red) wire will cause the HVAC system to begin cooling and the fan will be turned on automatically.

My air conditioner will only turn on for a moment then shuts off


it sounds like you have a thermostat problem you can either take the thermostat of the wall and check the wires to see if they are all connected, or you can replace you t-stat. you also could have a bad contactor. without having technical knowledge it will be hard to fix, your best bet is to call an A/c shop and have a tech look at it.. it shouldn't be too pricey. 60 for the tech to diagnose it and if its the contactor it shouldnt be much over 100 dollars.

there could be a short in the wire. meaning that its not getting the proper voltage. do you have any other symptoms? make sure that the breaker is not tripped, and if it is, it very well could be from the dogs eating at the wires. that could also kill your dogs if they get hit with that voltage coming from the wries.

Condensing unit


Probably one of the wires going to the control board or contactor has been pulled off when this happened. If you feel comfortable trying to reconnect these comment me back and I will try to walk you through it. PLEASE REMEMBER THAT THE CONDENSER HAS HIGH VOLTAGE INSIDE OF IT.
