Sons dog chew his thermostat wiring on the outside of the unit in to. 2nd time. now fan on compressor won't run. I can hear the compressor click so I think the wires to the themostat are messed up. No furnace attached (boiler unit)

Sounds like there is no control voltage. Either the transformer to reduce the voltage from 110 volts to 24 volts is not producing the 24 volts needed for control voltage, or most furnaces have a small 3 or 5 amp fuse mounted on the main control circuit board that may be blown. Other "outside circumstances" may involve a break in the thermostat wire...more than likely the red wire if you are getting nothing to work. I have seen evidence of "critters" that have chewed through the low voltage thermostat wiring that would keep the thermostat from controlling anything. To check this, go to the furnace and jumper the red & green wire to get the fan running just to isolate if it is a thermostat wiring severred. Good Luck.
Your unit is running in heat pump mode...hope you knew that you had a heat pump...
Anyway the problem would either be the thermostat or the reversing valve...
It will take some detective work to figure out exactly which is causing your problems...
Hi, If you have what is called a heat pump, the outdoor unit is supposed to run. It has a reversing valve which reverses the flow of refrigerant and the indoor unit becomes the condenser and the outdoor becomes the evaporator coil. Now, if you don't have a heat pump and the furnace is gas fired, then the control wiring or thermostat is calling for both to come on. Control wiring has to be touching together somewhere and bringing on both. Look over the exposed stat wire outside if you have a dog that may have chewed the wires, I have seen this happen. If all wiring looks good, then the stat is faulty and must be replaced. Make sure you don't have a heat pump first, as the fan, compressor, and all will run on heat and cooling. I hope this will solve you're problem, please let me know, I would like to hear back. Sincerely, Shastalaker7
It sounds like the thermostat wire going to the condenser is ground, It either got pulled loose and is touching the housing or as in most cases the wire got cut or was chewed by an animal. You need to turn electric off to both devices and physically inspect the thermostat wire going from the air handler to the outside unit, also inspect where they connect inside the unit. When you find the break, cut and strip each individual wire and securely wire nut each conducter red to red white to white and so on. There you go all fixed. That's when I give you the bill for $75...except this time you write that check to yourself. Good Luck
It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.
Definately get this checked out. Some thing has shorted just enough to let voltage "Feed back" and keep the fan running. Could be capacitor, wires rubbed through each other, etc. A reset is a safety that is used when there is an overcurrent or over pressure situation. No reset set for this situation.
There is always an outside chance that if you touch the unit while standing on wet ground, you may get shocked. I firmly believe that something is allowing power to the fan in a feedback condition so don't let this go as it may cause damage to other parts.
Good Luck and let me know how you make out on this.
we are trying to install a goodman heat pump with a rheem air handler, the orange wire is hook up and the unit is still staying in the heat mood. does anyone have a wiring diagram for the air handler, their is some white wires in the air handler one with a purple strip and one with a black strip we need help
Check your wiring between the contactor and compressor for a short to ground, or check the compressor windings for short to ground.
With the Tstat off, the contactor should be open so the only way for the compressor to be trying to do anything is if the 110 volts from the unbroken side are traveling through the compressor to ground. Since 110v is not enough to run it, the overload is kicking it out, cooling off, and repeating the cycle. When you kick on the Tstat, the contactor is supplying voltage directly to ground without going through the resistence of the compressor windings and kicking the breaker.
Post back and let me know what you find.
