While the compressor is running this unit pulsated as it turn of and and as the relay on the adaptive defrost clicks. I replaced the adaptive defrost and all was good for 5 days. Not sure what is causing this and no one has heard of this. Any help on this is greatly appreciated.

What do you mean by turns off? Is it only the compressor or are the evap and condenser fans turning off as well? How is your power source? Is the fridge on a separate non-gfi circuit? Are these the same symptoms before replacing the adc? If the fans are turning off, try bypassing the cold control. Also disconnect the icemaker as I've had an older fridge that had a strange power problem due to a bad icemaker.

I agree. Shorted heater in icemaker causes a few different voltage issues. Also check defrost heater and bimetal for shorts. Check for any black discoloration of the copper tubing near the compressor. Had a lot of crazy voltage issues on refrigerators a few years ago due to sulphur degredation from guess what? Chinese drywall.
