Can a bad thermostat trip a breaker?
The thermostat or furnace control is turning on a component or causing a load on the breaker that is causing the breaker to trip. There is actually a separation of the thermostat power circuit and the electrical circuit that powers the furnace. So the thermostat is probably not the circuit breaker tripping culprit.
How do you know if your AC breaker is bad?
