Kenmore Condenser fan motor replacement woes..

I had a problem with the condenser motor on my fridge not coming on every time causing the unit to get hot and thaw everything inside. I could usually take the dowel and spin the fan blade to get it to start. I ordered a replacement motor that arrived the other day. I removed and installed the motor as instructed on the paperwork provided. When I went to plug in the unit it now trips the GFCI the fridge is plugged into. I removed the motor to check and see if it was bad. When I place the motor on a 115v AC line it turns the fan motor fine and nothing trips. What is going on here?
Quick response needed as food is defrosting as I type.:eek:

I just checked one other thing. If I turn the defrost control timer dial to the defrost setting and plug the unit in it does NOT trip the GFCI, When I turn the defrost timer dial to start the unit again it trips the GFCI. Almost sounds like a relay is bad or shorting out. Thoughts?

In general, pros. do not recommend putting a frdg on a gfci outlet, too many places for a frdg to have ground currents.
If you have a meter, I would check the new motor for a short to ground and also the compressor.

The fridge is in the Garage and every outlet is GFCI protected. It has been in there for 5 years and has never tripped the GFCI until today. I Ohms tested the motor and it reads .071mhs, the old motor reads .068 ohms. I took the new motor and put it directly to a power strip in the garage connected tot he GFCI and the fan motor turned with no issues. I also reinstalled the fan motor into the fridge, placed the defrost timer to defrost and the unit turns on and doesn’t trip the GFCI, as soon as i turn the defrost timer to the off position normally allowing the compressor to reun, the GFCI trips.

If you do the same test with the fan motor disconnected does it still trip the GFI?

I ran an extension cord across the house to Non- GFCI circuit and the unit works as designed. I guess with it defrosting some condensation must have been in the Compressor circuit. Fixed. THanks
