Original problem was hot strip between fridge and freezer - cleaned coils and was better, but still too warm. Replaced condender fan and motor - fan started and ran a short time (30 seconds or so). Unplugged fridge from socket, waited 1 minute and plugged in again - waited 7 minutes and fan came on again for 30 seconds and never restarted. Repeated this three times with same result. Temporarily, have a small fan pointed at compressor and coils and everything is fine - fridge temp is 37, freezer is 0 and strip between the two is normal. What should I try next? Thx.
