Hello and thanks for reading this post!
I was called to a CGAC unit that shows the following:
Compressor 2 is running and loading and unloading, compressor 1 is off with all 3 LED's off (LEDs on the honeywell control) Safety check ok.
Why would compressor 1 not try to start?
Second problem: There is another of these units close by that will not run at all.
When power is applied, the control starts flashing the LED second from the top (compressor 1) this is also the start mode LED. Safetys check good on this machine as well.
Thanks for any help!
