My Amana has been having intermittant problems. A couple weeks ago the coils froze up, I tested the defrost timer, heater and thermostat and all checked out ok. After reading so forum posts, I ordered a new defrost timer. While waiting for the part, I took the fridge out on my deck and blew all the accumulated dust from under the unit with an air compressor. After hooking it back up it worked fine for 6 days, then we came home and it was completely defrosted. I unplugged it and installed the new defrost timer, after plugging it back in, the fan started but the compressor did not. The compressor was hot to the touch. I unplugged it again and left it that way for 2 days. Yesterday I called a neighbor who has been in the refrigeration business for 40+ years, he came over and said the compressor checked out ok. When I came home from work last night, I plugged it back in and heard the compressor start up. A couple hrs later it still hadn't cooled down and I heard it trying to cycle on and it clicked back off quickly several times. When I checked it this morning it still hadn't gotten cold. Stopped back home during work about 3 hrs later and it had made ice in the ice maker. 6 hrs later when I get home from work it's still cold and running. What's happening with this? New compressor about 18 months ago.

Condensor fan is running, but compressor is not. It will run for 5-6 days great, then one day it is not cooling and the condensor fan is running. The compressor pulls 6.2 amps when I first started it and gradually climbs up to 6.7 amps
