Check for power at the contactor. If no power there, check the circuit breaker, disconnect, or fuses. If there is power at the contactor, set the thermostat to call for a/c then check the contactor to see if it is pulled in. If it isn't check for 24vac at the contactor. If no 24vac then go to the thermostat and place a jumper between R and Y; that should make the contactor pull in if everything is good. If it does pull in when you install the jumper the problem is your thermostat. Let me know what you find.

I have an LG front load washer and I can't start the machine, the power button will not respond. I have power to the unit because the interior drum light has stayed on. Any suggestions?


The starting capasitor on the motor could be faulty. If this happens the machine would not start running. A method to check if it is the starting capasitor, is to open up the washing machine covers and once the button is pushed - give the motor a turn by hand to see if it starts running. This should only be done by a qualified person as it is dangerous if you do not know what you are doing.
If the washing machine motor starts running, then the capasitor if faulty and needs to be replaced,
Trust this will help you.

Andre

Test the capasitor in the compressor unit there it could be bad or the compressor froze up.
there is a clicks on over load device inside the plastic box on the side of the compressor some

Compressor wont turn on. fan runs central unit


first check you thermostat settings and make sure that it is on a cooling setting if ok it can be the fuse that sends the power to the outside unit if fuse is ok it can be the capasitor for the compressor if ok you may have to check the compressor for open windings or ground fault so you will have to replace the compressor or the relay which is after the thermostat

I have a 33 gallon craftsman compressor model #919.167330. If the air is totally out of the compressor and you plug it in, it will build to full pressure and then turn off normally. When you begin to use...


i think you will find there is nothing wrong with the compressor part of this its all down to a faulty motor
if it cant start up the motor the motor will hum at first then the circuit braker pops out? yes???
check your getting full mains power first as if its trying to run on a very long extenshion lead its not getting the full power to start up, and you will need a much heaver lead,,,if its in a plug on the wall, change the capasitor on the motor,,,this is the part that hold a lot of volts to kick start the motor over when it first trys to start,,if this capasitor has droped in holding its charge there wont be enough volts in it to kick start the motor over,,so the motor starts to hum first trying to start but it dont stand a chance of spinning up
so it keeps pulling more and more amps till the braker pops out,,,watch this capasitor it can realy bite you if you tuch the two ends that are live????
the motor has two windings in it,,a start up winding and a running winding,, if its been humming for some time now it could have damaged the start up winding

Amana side by side. compressor sometimes won't start, overloads and cycles that way until you unplug the unit for an hour. After that it usually starts and runs. Bill


YOU MAY HAVE A PROBLEM WITH YOUR RELAY/OVERLOAD OR POSSABLY CAPASITOR. ALL THREE MAY COME AS A KIT. IT ALSO MAY BE A WEAK COMPRESSOR SO ITS A GAMBLE.

Home unit 3 ton won't run


The small capacitor is for the fan motor the other for thecompresor .You can try conecting a booster (or hot start) in paralel to the comp.capacitor .If this doesnt work you have to replace the compresor.

Intertherm 3 ton ac unit I took the capasitor off to get a new one and forgot how to wire it it is not on the cover three wire fan and compressor three prong 55-5 capasitor help


The 55 terminal is marked "herm" it goes to the start winding of the compressor. The 5 terminal is marked "fan" it goes to a wire from the fan motor. The common terminal goes to one side of the power line...The side that is NOT going directly to the compressor.

Hi the compressor on my split air conditioning unit will not cut in .the indoor unit runs and the compressor light on the indoor unit lights up?


If the system is appearing to turn on, but no compressor, Check the capasitor on the condensor unit. If you open the service panel, you can test the compressor by pushing in the contact switch. If you push the switch and all comes on, Replace the thermostat after checking to make sure the thermostat wires are not cut or disconnected. The capasitor usually looks like it is swelling if it has gone bad
