Although your furnace and AC may use natural gas, electricity, propane or oil to heat and cool your home, it needs a good dose of electricity to power all of its electrical components. Some of the largest parts in your furnace and AC that use electricity include the blower motor, AC compressor, circuit board, as well as the gas valve. If you have an older furnace, it may utilize a standing pilot light instead of an electronic ignition source.
The most common cause for your furnace or AC to trip your circuit breaker is your blower motor overworking itself. The blower motor can begin to overwork itself when air flow to the motor becomes restricted. One of the largest causes of this is a dirty air filter. If you haven’t changed your filter in a while, be sure to check to make sure it is not dirty.
Here are some FAQs to consider

Yes, a bad thermostat can cause your furnace not to work. When your thermostat is unable to properly register the temperature in your home, it fails to communicate with your furnace to turn it on. If you believe your thermostat is the reason your furnace is not working, you should check the power supply to the thermostat and inside the thermostat to check for dirt, dust, loose screws or loose wires.
