My compressor cooling fan quit- the compressor still runs. I unplugged the unit then plugged it back in. The cooling fan ran for about 15 seconds, then shut off again. Is the problem with the main control circuit board or with the compressor control board?.....

Condenser fan motor or motor wiring is bad. That compressor should never run without the fan. Good luck.

yes the mother board is located under the plate in the back.. but when you replaced the relay did you put on a 3in1 relay or a manufactured relay?

An abrupt cycle of power can cause a motor to run backwards. If you turn the power off again and wait 10 seconds or so (enough for blade to stop spinning) it should run the right way. Put the capacitor back the other way and try again.

Hello, pull the unit out away from the wall remove the cardboard or metal cover down the bottom which will give you access to the compressor area. Assure that the compressor fan motor which is the fan that cools the compressor is running if it is not then you will have to replace the compressor fan motor. Unplug the unit until the compressor cools if you leave the unit plugged in for a long time you can cause damage to the compressor itself. . If you do not have another place to store your food until you get the new compressor fan motor leave that cardboard or metal panel off the unit if you happen to have a large box fan put it in back of the unit this will cool the compressor until your new part arrives. I have had to wait 8 days for a compressor fan motor at one time and the customer I repaired the unit for had no other place to store there food. Note this fan has to be constantly running on the compressor until you are able to replace the compressor fan motor. If you have any further questions message me back Thanks

p.s make sure you have your model number when you order your part I tryed looking that model number up but it did not come up on the look up site if you need me to locate the part number that you would use to order the compressor fan motor message me back the make and exact model number of your unit Thanks again

Your unit uses both the capacitor and a contactor (relay) to start your compressor and motor. With the indications you are giving it would either be the capacitor or the contactor - and since you have already changed the cap - then replace the contractor!

NOTE: We always recommend that you change the capacitor and relay at the same time, because they seem to fail at about the same time.

Lubricate the condensor fan with a parifin based oil like Union 76 turbine oil or "Zoom Spout" oiler. These fans are notorious for the bearings drying up on them.

Being careful.... touch the compressor copper lines. One should be very warm almost Hot to the touch.
Also with the unit unplugged..... note that there is a coolant drier with a small capillary tube coming out of one end. Tap the side of this by holding a hammer handle (wood) against it and hit it on the side with a screw driver handle.

Check to make sure the evaporator fan in the freezer compartment is also running when the compressor is on. Anytime the compressor is running BOTH fans must be running. If you can not get the condensor fan up to full speed you will note that the chassis around the door seal area will be quite warm almost hot to the touch and the unit will not be cooling properly. Just for troubleshooting.... direct a fan at the condensor coils and see if the freezer compartment gets cold and that the chassis around the door seals is just warm.

Note about compressors in general.... if you unplug a unit.. it must settle / stabilize for 15 - 20 minutes so that the compressor can restart. Any power off periods less than 15 mins will result in the compressor cycling via the thermal overload every 4 minutes or so... and it does not run for more than 40 seconds when the overload kicks off the PTC relay power.

If you never feel the copper line off of the side of the compressor get hot then the unit has lost coolant.

1. is light on in side when you open the door. If not check breakers or fuses.
2. Can you hear the compressor running. If not do you hear any clicking sounds.
3. If you hear clicking sounds, try putting a fan on compressor and unplug refrigerator.
4. Wait one hour.
5. plug back in. If compressor starts let it run and see if it cools, if it doesnt, call service man.
6. If it goes back to clicking, call a service man.

I had similar problem: condenser fan was running, but compressor was not. After I unplugged refrigerator for a while and plugged back on, the compressor ran for a few seconds. Compressor testing indicated it was OK, I suspected that it was either overload/relay or run capacitor. My limited testing equipment could not tell me which one was bad. I took out the run capacitor out of system by unplugging the 2 wires and the refrigerator ran fine. After Replacing the run capacitor with a new one bought from partselect.com, it ran fine so far.

compressor overheated or stuck. also check starter relay...maybe broke.
if ever thing is alright,

let it stand for about 4 hours unplugged to cool the compressor.

plug it after 4 hours and if the compressor would still run for 10 seconds, then you have a faulty compressor.

tnx 4 using fixya,

There is no reset switch. There is a thermal overload protector mounted on the compressor. Does the compressor hum and then give a click sound. If so your compressor has failed. If the compressor is cold (Room Temperature) and it does not try to run your thermostat may be bad. If so remove the temperature control and jumper the two main wires that connect to the control. Unit should be unplugged to do this operation. Insulated the wires so they do not contact any metal surface. Plug the freezer back in. If it runs and cools replace the thermostat.
