Question about Kenmore Heating & Cooling

1 Answer

Kenmore a/c window unit fan not kicking on with compressor.

This is an intermittent problem. The unit works fine for weeks at a time, but sometimes has the following problem: The compressor will kick on, but not the blower. The blower is not stuck, it will move freely. After a minute or two the compressor sounds labored and kicks off. After a few more minutes, the blower will kick on all by itself, without the compressor. It doesn't matter which fan speed is selected, or whether is is one of the constant fan speeds, or power saver speeds.

Likely a bad motor, when this occurs verify the board is sending voltage to the motor.

SOURCE: DH30 Dehumidifier Compressor Does not Operate

I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.

SOURCE: 2 problems.. AC Comp cuts out. And Fan will not stop.

Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!

What causes compressor to work fine then shut down and not come back on for an extended amount of time?


Sometimes these AC's need to be removed and given a damm good cleaning with a spray hose, and any filters replaced. Clean the internal fan(s).
This can sometimes fix overharting of the compressor or misleading air temp sensing..

I have the a Kenmore dehumidifier sometimes it runs fine and other times just the fan runs not the compressor or just the opposite the compressor runs not the fan it is only 2 1/2 years old. What should...


Kathy, I'm not sure you have a problem with the dehumidifier. Depending on which mode you're operating it in, the fan will run in an effort to recirculate the air. If the humidity level rises above the level you have the unit set on, the compressor will then turn ON. This is particularly true, if the unit is operating in continual mode. Then there are other times the fan isn't active, but the compressor turns on when the humidity sensor feels a rise in humidity. So, for the most part, I don't think it's a problem.

Just be sure that you clean the air intake filter at least once every two weeks, during times of daily operation.

Hope this helped you. Please let me know. Thanks.

Take it back or call Sears. A 2 week old unit should not do that. I'll assume the settings are right like set on AC Auto or Max cool and not just fan. Are the coils icing or were they icing behind the filter? If not, I think it may need to be serviced.

Freezer works Refrigerator will not cool down


The compressor should be OK this time because you caught it in time. But if the condenser fan stops you need to consider replacing the fan. I have had refrigerators do fine until the fan motor warms up and you are away, it stops. Don't think you should use the refrigerator until the fan is fixed. Sea Breeze

Hello, I have a Kenmore 580.75124500 ac/heater


It is probably the compressor. You will need to check if the compressor is being called to come on. Do you hear the compressor running? If you do, I would remove the unit from the wall or window, and wash it down real good with a hose being careful not to get the electronics wet. If not and the unit sound different than it did before, it's probably time to buy a new one.
