For Whirlpool Compressor (Part Number: AP3108704)

Upon returning to our summer home, found fridge not working at all, except for lights and fans. I checked that power was getting to compressor and it was. I don't hear the expected sound of the compressor working. Copper tubing in and out aren't hot or cold. Since I don't see access ports to screw on a pressure gauge as in a car AC, how can one tell if there is R134 in the system or not, and/or the compressor itself isn't working?I can measure the AC current. Would that help in the diagnosis? Thanks for any help on this. P.S. Is my estimate of $400 to $500 for a compressor replacement and R134 recharge way out of line?

ANSWER Retiredlucky, If the compressor feels warm then you will want to check the start relay on the side. Pull the relay and shake it and if it rattles then the relay is faulty and would need to be replaced.
