Compressor won't work. the fan runs but not the compressor

To clarify, the compressor and fan will run in defrost mode. The compressor and fan runs to dry out the air blowing onto the windshield.
Now if the condenser fan runs in "heat" you may have a problem with the fan relay or the main controller.

switch/ fuse possible if it has one, if not one of the wire going to the motor was severed, or the start up capacitor of the motor if it also has one.

as long as the compressor is running on your freezer the longer the fan runs has to too cool the compressor . . .thermostat problem

It may have a faulty compressor relay or overload, best to change both at the same time. It's either that or a bad compressor.

First let me ask, are you sure the compressor is running? If you verified that it was running by vibrations in the compressor area just know that the condenser fan can also cause those if your machine has one. The way to tell is if the compressor is generating heat. With that said, assuming that the compressor is running, and all applicable fans are running, you need to determine if the machine was losing cool over time or did it happen overnight? If the latter of the two you'll need to isolate where the leak is, be it the evaporator or the compressor area. To actually add freon to the system if no access ports are available you;ll need to get a piercing valve, I personally use pt# bpv-31 bullet piercing valves.

Hi simpsonruth1..
In the back of the compressor motor you will see a fan, remove the plastic cover to get to it..
Once you have the plastic cover removed and the fan exposed, plug the compressor in and spin the fan with your fingers...be quick as the fan could cut your fingers if you do not get them out of the way..
If the compressor starts working, then the start capacitor is bad on the compressor...if it does not run then you have motor troubles, either replace the motor or get it rewound.
Please take time to rate me

My first reaction would be to look inside the freezer for ice buildup or if cooling at all. Check that freezer fan and condenser fan are also working when the compressor should be working. Then if everything is working topside as it appears to should be working but not cooling I would pull the refrigerator away from wall, unplug power, remove lower cover over compressor and then feel top of compressor with my hand to see if warm, cool or too hot to keep hand there. Here is a photo of compressor parts=> MSD2756G Compressor Components In that photo there are three parts I want you to consider as possible reasons if compressor is not running but very hot to the touch.A small percentage of the time it is the compressor itself that is defective and it would pay to do the test of compressor listed on this page HERE and listed near end of page as How To Check For A Burned Out Compressor.Tell me if both fans are on because that tells me the thermostat is good and calling for cold. Here are the most likely reasons your compressor may not be starting=> 12002794 Relay and Overload Kit, and 65889-4 Run Capacitor

I looked up your model. This is a self defrosting model which features a fan motor for the compressor and the evaporator. If either of them 2 fans is out then the freezer won't work well. That is the first thing I would check. If only one of the fans is gone out then replace that fan and rock on. If Both fans and compressor are not working then hunt down the timer. It may be stuck in defrost mode. The timer is nestled up behind the cold control and light bulb inside the nice little console in the fresh food compartment. Look under the console for a hole about the size of a dime. Inside that hole a timer advance. Use a flat blade screwdriver to advance the timer till you hear the compressor and fans come on. If the timer is fine the next thing to look for is ice buildup inside the evaporation compartment. If you see that then the defrost heater and termination thermostat needs to be replaced.
If both fans operate ok but the compressor is not working then I would remove and inspect the compressor relay for wear. The cold control would be the next thing to take a look at. If it is open the compressor and fans will not run but the inside light will work.
