Hi!
I have a ClimateMaster VHS Series (model 81620GSPXXCAQ) water-source heat pump installed in a high-rise condo.
The fan works fine, but the compressor will not run. The CXM controller (model 17B0001N01) is not locked out, and no fault codes are present.
When the thermostat calls for cooling (or heating), I can hear a buzz that I was pretty sure was coming from the compressor contactor, so I gambled $23 and replaced the compressor contactor to no avail.
Any ideas?
Thanks! |
