Condenser Fan Motors
Recently went to a service call.
Complaint was that the temperature rose for a short time in a server room. served by a Roof top unit. then it returned to normal. i checked the unit over and found nothing wrong.
I found the thermostat needed recalibrating. and thought that was it.
our service manager got called out to the site again and found the condenser fan motor was failing.
I shook the shaft when i was there and felt no side to side motion. and i checked the amps. all OK. Contactor fine. fan cycling control good working order.
What other checks should i have done on the condenser fan motor?
