Ruud heat pump outside unit not starting. Open and found contactor disengaged even though I have system on from inside. Low voltage wires come out of a circuit board checked for 24v, none. Then bypassed board by unplugging same yellow and brown wires plugged into the board and exiting but now I have 24v getting to contactor but it does not engage contactor. What could the problem be. I know a little a/c but these heat pumps are very complicated. Help please, I want to learn.


If you are getting the low voltage to the relay and it is not closing, then the relay may be either bad or stuck. Disconnect the 220v and see if the contacts can be manually closed. I always use a piece of wood or something non-conductive. If the ... Air Conditioners

I have a Tempstar model NFCP3600A1 (style # FCP3600A) ICP Heat Pump. Starting last week, the unit kept heating well over the set temperature. I swapped out the thermostat thinking it went bad, but it still continued heating and the "off" wouldn't work at the new thermostat either. Next, I checked for shorts in the thermostat wires and they seemed OK. I then replaced the TI 26FC-2 circuit board. Once the unit heated the house to the set temp, it continued running up to 75 degrees. "Off" and lowe

My Mitsubishi Mr. Slim heat pump (indoor unit MSZ-A09NA / A-15NA / A12NA / A17NA, according to the operating manual; outdoor unit MXZ-3A30NA) is not providing heat. The left green indicator light blinks when I try to restart it (Breaker, emergency heat operation), so I've turned it off). The problem began when I was clearing the condenser of 3 feet of snow and ice. The fan inside the condenser can move freely.

I have an old Miller 3 ton heat pump. It will work fine sometimes but when it decides not to work i can go outside and press the power contactor and the unit will come on as long as i hold the contactor pressed. A friend told me the defroster board could be the problem because when its cooler than 45 outside it wont come on by itself. But when i measured voltage at the thermostat no wire had 24volts.When it runs it runs good and cools or heats the house well.


It sounds to me you need just a really good tune up maybe a new contactor retest your low voltage what do you have from common to 24 volts it should be 27 volts if you test each wire you want get 24 v it will be like 7 or so ... Air Conditioners
