The system was working fine; 2 weeks ago I disconnected the thermostat to do dry wall repair and painting. I turned the breakers off to the air compressor but forget to turn off the breaker(s) to the furnace.
I reconnected the thermostat (5 color thermostat wiring) and the system won't start up. I took pictures of the old wiring to ensure I would connect it correctly. I bought a new thermostat-- it's still not starting. I can hear the thermostat "clicking" to start the AC but the system in the basement does not turn on (neither does the air condenser outside).
Here's what I tried:
I flipped all the breakers off and back on.
Used a voltage detector to make sure the power supply is live.
When the thermostat was connected I removed the battery to see if the therm. would stay powered on; it did not. Shouldn't this stay * Isn't the battery for *
I removed the panel on the system-- there's a sticker which lists codes for a "red light." example, a double blinking red light might mean a power failure. I don't see a red light anywhere.
What should I try * If the thermostat is not receiving power, should I try replacing the thermostat *
Would removing the thermostat for 2 weeks cause damage to the * Are there * Or a reset **
