Understanding Your Furnace’s Reset Button
The reset button on a furnace serves as a critical component designed to address temporary malfunctions. Typically found on the front of the furnace or within the blower compartment, it is often a red button. Pressing this button can temporarily solve issues like pilot light failures or overheating, allowing the furnace to restart and function normally.
Why Is the Reset Button Important?
The reset button is often a last resort for homeowners who are experiencing issues with their heating systems. It provides a simple way to restart the furnace in hopes that it will resolve the underlying problem. However, a reset button that does not work can signify more significant issues that need to be addressed.
Common Reasons Why the Reset Button May Not Work
Understanding the reasons behind the malfunctioning reset button can help you determine the best course of action. Here are some common causes:
1. Overheating
Furnaces are equipped with safety mechanisms that trigger a shut-off to prevent overheating. If your furnace has overheated, the reset button will typically need to be pressed to restart the system.
