I'm trying to troubleshoot a non-functioning AC. The fan does not come on and there is no cool air/condenser does not run.
My thermostat is a Braeburn. Three things I'd like to try for troubleshooting, but are they safe:
Can I safely just jumper between the G and RC posts at the thermostat to see if the ran comes on?
Can I do the same between the Y and RC posts?
I have other Braeburn faceplates (the AC and the heat are separate systems and the house has 4 zones for heat so I can 'borrow' a faceplate from another location) - can I safely pop one of those on the one thermostat that controls the AC to see if the Braeburn is shot?
