How to Reset a Lennox Gas Furnace: A Step-by-Step Guide
Resetting your Lennox gas furnace can help resolve common issues and ensure it operates efficiently. Follow the steps below to reset your furnace safely.
Step 1: Turn Off the Power
Before you begin, safety is paramount. Locate the power switch for your furnace, which is usually a toggle switch near the unit. Flip the switch to the "off" position to cut off power to the furnace. This step is crucial to avoid any electrical hazards while you work on your device.
Step 2: Locate the Reset Button
Next, you need to find the reset button on your Lennox furnace. This button is typically located behind the front panel of the furnace. Look for it on the blower motor housing or near the igniter. It is usually a small, colored button—often red or yellow. If you have trouble spotting it, use a flashlight to check around the burner area or along the limit switch panel.
Step 3: Press the Reset Button
Once you have located the reset button, press and hold it for about 3 to 5 seconds. During this time, you may hear a clicking sound from the furnace, indicating that it is resetting. After the time has elapsed, release the button.
Step 4: Restore Power to the Furnace
Now it’s time to restore power to your furnace. Flip the power switch back to the "on" position. Avoid touching any other components at this stage. Wait a few moments for the furnace to reboot and start running again. If there are no underlying issues, your furnace should return to normal operation.
Conclusion
By following these simple steps, you can effectively reset your Lennox gas furnace and potentially resolve any minor issues you may be experiencing. If the furnace continues to have problems, it may be necessary to consult a professional technician for further assistance.
