What Is the Comfortmaker Furnace Reset Button?
The reset button on a Comfortmaker furnace is a safety feature designed to restart the furnace’s control board after it detects a problem that causes the system to shut off. It helps reset the system in the case of minor errors such as overheating or ignition faults. This button is usually located within the furnace’s control panel or near the burner assembly. Its primary purpose is to protect the furnace components and ensure safe operation by preventing continuous running under faulty conditions.
When Should You Use the Furnace Reset Button?
The reset button should be used under specific circumstances:
- Furnace Failure to Ignite: If your furnace repeatedly fails to light, hitting the reset button can restart the ignition process.
- Unexpected Shutoff: After a sudden shutdown due to safety lockouts like overheating or flame sensing issues.
- Power Interruptions: Following power outages or electrical surges that disrupt the furnace operation.
If the furnace requires resetting multiple times within a short period, it is an indicator of a more serious issue demanding professional service.
Step-by-Step Guide to Resetting Your Comfortmaker Furnace
Resetting your Comfortmaker furnace is straightforward but requires caution.
- Turn off the furnace power: Locate the furnace switch on the wall or the breaker box and turn off the power supply to avoid electric shock.
- Find the reset button: Open the furnace control panel and identify the red or white reset button.
- Press and hold the reset button: Hold the button for about 5-10 seconds, then release.
- Wait before restarting: Allow the furnace a few minutes to cool down if it overheated.
- Turn the power back on: Restore power and observe if the furnace ignites and operates normally.
Common Reasons Why the Furnace Needs Resetting
Using the reset button often signals an underlying issue. Common causes include:
- Dirty or Clogged Filters: Restrictions limit airflow, causing the furnace to overheat and shut off.
- Flame Sensor Problems: Dust or corrosion stops the furnace from detecting the flame, leading to shutdown.
- Thermostat Malfunctions: Incorrect signals cause the furnace to turn on or off unexpectedly.
- Ignition System Failures: Faulty igniters or control boards disrupt the startup process.
