My refridgerator is not cooling or freezing and was wandering what I can check to see what the problem might be. The fan is coming on but the compressor is not.

ok unpluged the compressor and checked for vac and I do have one pin at 123vac. your next desc. of checking continuity between the pins and compressor not grounded was a little iffy so I hooked my ground from my multimeter to the fridge ground after I removed it from the compressor and probed the 3 internal pins on the start component and all had some continuity. 1 at 1.7, 1 at 6.3, and one at 107.3. Please let me know if this means the start component is bad or what I might check next. I also should give you more info on the unit. When it quit working the freezer side stopped working off and on for a week, and with everything hooked up you can hear the compressor try and start for about 5 to 10seconds and shut off and thats all it does.

Hi.

To check if the compressor is "grounded" touch with one meter probe any compressor pins and second probe to any copper tubing.
If you read continuity - compressor is bad.

So if you'll establish that compressor is not "grounded" and there is 120VAC to the start devise you need to replace the start devise.

Thank you.Post the results.

Simon.
