I replaced my thermostat, during which two of the wires touched and
produced a small spark. The C wire was not one of them, but I think it
was either the O or B wire. Anyway, now that the thermostat is in
place, nothing will run. The fan or heat pump, not on heating or
Everything is on and not tripped at the circuit breaker, so I worry
that I shorted something.
The heat pump worked fine before I replaced the thermostat, so I doubt
anything is wrong with it, and it was replaced just over 2 years ago,
so it's still very new.
When turning on cool or heat at the thermostat, it does make a click
noise as if it were switching something on, but nothing runs. I've
double-checked the wires in the thermostat, and everything appears to
have been wired properly.
Any ideas or suggestions would be appreciated. Thanks.
