Refrigerator is not cooling. Compressor comes on than off after 20-30 seconds

This is a common problem with refrigerators. The first thing that you want to check is the relay and overload on your compressor. I know this blog is about an LG refrigerator but it will be the exact same way on your Kenmore.

2 possible issues. If compressor running, but not cooling - No freon in the system, or compressor valves are bad, not compressing freon. Ideal would be to check pressures on the system while its running. Could be some kind of restriction. most common problem i would guess low freon level. Here are 2 of my videos i have on my channel. first is leak found at evaporator coils. i used leak dye to find it, second video is replacing compressor, but had compressor completely down. installed 3-n-1 hard start kit, but compressor did not come on, so replaced compressor with filter drier. Hope this will give you an idea what to do next.

Hi,

Many times a freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong.

If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.

First, answer these questions: Is the refrigerator completely dead? If so, see “It's stopped completely.” Is the thermostat knob turned to the proper setting? If not, reset it.

Next, see if the compressor motor is running The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help. If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

• The compressor
• The Thermostat
• The overload, relay, or capacitor
• The defrost timer
• The condenser fan motor

One of two things bad compressor relay or bad compressor

if unit is coming on for a few seconds and then u hear a click, you may have a bad compressor relay. pull it off the compressor and shake. most times u will hear a rattle of junk. if so its bad.

Are you sure that the compressor actually runs, if it does start up and run, I would suspect a blockage in the refrigerant tubing around the filter drier where it is reduced to capillary tubing. If the compressor is just trying to come on, then switching of, I would try changing the starter relay first.
