Hi all,

Replaced a thermostat yesterday. Coleman Eb12 and DRHQ0421cd. Turned breaker on and saw a flicker in the house lights. Now fan does not come on. nothing comes on.

wondering if the x wire in the original thermostat got put into the b on the new could cause the control board on the outside unit to "go bad". Does the outside unit control board have the ability to go bad and not allow anything to work?

If you crossed up the wires, may have blown a transformer. Would have to look at wiring diagram and trace the circuit to see if power was/is lost.


Thanks,
Robert
