Hermetic compressor
Hi
I've been called to a display chiller (made by Frigor Pastor). The compressor is starting up, and running for a couple of seconds, shutting off, with a squeaking noise. I've checked the system over and noticed that one of the two condenser fans is not working, due to a bad fan motor. It's on R22, and the pressure is 120psi on compressor start. The HP starts to rise (not by too much) and the LP drops, as expected. When the compressor trips off, the pressures equalise.
I've put it down to the compressor going off on internal relief, being caused by the broken fan causing condensing problems.
Any other opinions ?
