If your furnace does not have a power switch, then directly turn off the circuit breaker connected to the furnace. Open the blower housing and find the reset button. Press the reset button and hold it until it clicks. Turn the breaker on to get the furnace running. The furnace will start as soon as it receives signals from the thermostat.
Once the control panel is open, look for a small reset button or switch. Press and hold the reset button or switch for about 10 seconds. Release the reset button or switch. Close the control panel by securing any screws or clips. After completing these steps, your electric furnace should be reset and ready to use.
The furnace reset process may differ a bit depending on the type of furnace you have. Locate the furnace power switch near the furnace and turn it off. If there’s no switch, turn off the main circuit breaker to the furnace. Wait for about 10 seconds. Turn the switch or breaker back on and check to see if the furnace is running properly.
