Answers :

Try to put a booster cap in parallel with the compressor capacitor ,but if still the compressor won't start it has a problem and because it's hermetic it has to be replaced.

Our inside unit Coleman EB20B (outside unit Goodman GKL 49-1) keeps blowing the in-line 3 amp thermostat fuse. We've rewired the wires in the wall, rewired the contactor wires, and the contactor was broken so we replaced it. We're still blowing the fuse. Could we have reversed the thermostat wires at the contactor? Or could the short be in the Blend Air box-this box is coupled to the thermostat wires? Thanks Ken Rohm

I have a mitsubishi air conditioning unit model MUH-12v. The fan on the machine outside has stopped and of course inside the air is not cold. Could this be a problem with replacing the gas or could it be a technical problem with the outdoor unit. Also I have noticed when I switch on the unit on the inside with the remote control that instead of two green lights comimg on I only have one green light flashing. Does that mean anything?

Hi, just replaced the capacitor thinking that would solve the problem but it appears it did not. The motor outside would kick on the unit inside would kick on but the blower motor inside works sometimes and wont other times. Basically, the unit will work just fine all day then we notice the house is getting warm, check the inside unit and everything is running fine but the blower motor is not circulating the air. I have a goodman a30-10 unit. I read where some people said the relay could be bad

Turn off the power to the air handler(indoor unit). Remove the access panel. From the motor,trace the wires back to the fan relay. One wire will probably trace back to the incoming power terminal. The other is the fan relay. It could be intermittent ... Air Conditioners

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 four Daewoo DSC-097L split A/C in my house in Mexico. One unit turned on with controller, then quickly turned off. Will not turn on again. Controller is O.K. Works on other three units.

My 1996 Motorhome Dometic 4 button Comfort Control suddenly does not recognize that the furnace is present. After wiring in a manual thermostat the Comfort Control suddenly recognizes the furnace. I take out the manual thermostat. I clean all the external contacts and then it continues to recognize the furnace thourgh about 15 test over 6 weeks. Pause 2 weeks and suddenly it does not recognize the furnace. What is going on. Could it be a sticky relay in the suburban Furnace?

My very old carrier 38 GR just twitches the contactor a few times every 2-3 seconds. Barely enough to cause the fan to move a quarter turn. If I jump the 29v coil supply from the control relay to the main contactor it starts and runs fine for an hr or as long as I leave it jumped. This is not an open hi or lo pressure switch. The transformer secondaries are all good. Does that leave me looking for CPCS board 38GR503344kK ? Thanks, Dan

My heat pump will not come on in HEAT or A/C. I thought I might have a simple defrost control board problem, but still no go after replacing the board and the defrost relay. I checked the pressure switch and it is not tripped. I've checked all the circuit breakers and they, too, are all set. I've checked the outside unit using the "test" switch inside on the start relay and the unit will come on, but won't stay running on it's own. When I select HEAT, I wait the necessary five minutes for the un

AC unit outdoor fan motor does not come on as it should, but if I manually start the contactor relay / coil by pressing and holding the manual button on it the fan then comes on and goes off with the thermnosat; however, the air stays cool (that is blowing outside) and warm inside. The large capacitor does not look bad though.

It sounds like the contacts of the contactor are burnt/pitted. When this occurs, it can allow enough current to operate the fan motor but not enough to operate the compressor. ... Carrier 38CKC036 Air Conditioner

Did check the screws on the wires to be sure they were tight.
