Understanding Your Furnace
Knowing your furnace is crucial for effective maintenance and troubleshooting. Familiarity with its components and operation can make resetting it easier and more efficient.
Types of Furnaces
- Gas Furnaces: Common in many homes, they burn natural gas or propane for heat. They often come with intricate safety features.
- Electric Furnaces: These use electric coils to produce heat. They tend to be less expensive to install but can lead to higher energy bills.
- Oil Furnaces: Found in areas without gas service, they burn oil for heat. They require more maintenance compared to gas and electric models.
- Heat Pumps: While not traditional furnaces, they can provide heating in winter and cooling in summer by transferring heat instead of generating it.
- Lack of Heat: This may occur due to a clogged filter, thermostat issues, or gas supply problems. Always check the filter first, as a dirty one can restrict airflow.
- Frequent Cycling: If your furnace turns on and off rapidly, the limit switch could be malfunctioning, or you might face insulation issues in your home.
- Strange Noises: Banging, squealing, or rattling sounds can indicate loose parts or mechanical issues. Pay attention to any unusual sounds.
- Pilot Light Problems: A blue pilot light indicates proper operation. A yellow or orange flame signals a need for maintenance. If the pilot light goes out, check for gas supply issues.
By identifying the type of furnace and recognizing these common issues, you can approach the reset process with confidence. Understanding your furnace helps you maintain its efficiency and longevity.

How to Reset Your Furnace
Resetting your furnace can resolve common issues and improve its performance. Follow these steps for an effective reset.
Step-by-Step Instructions
- Turn Off the Power: Locate the power switch on the furnace and turn it off. For safety, you can also turn off the circuit breaker.
- Wait: Allow the furnace to sit powered off for about 5 to 10 minutes. This gives the system time to reset.
- Turn the Power Back On: Switch the power back on at the furnace or the circuit breaker. Listen for any sounds indicating it’s powering up.
- Adjust the Thermostat: Set the thermostat to a temperature above the current room temperature. This signals the furnace to start heating.
- Check for Flames or Airflow: For gas furnaces, ensure the pilot light is lit. If it’s out, follow the manufacturer’s instructions to relight it. For electric furnaces, check for blowing warm air.
- No Heat? Check if the thermostat is functioning. Ensure it’s set correctly, and the batteries are fresh if applicable.
- Frequent Cycling? Inspect the air filter. A clogged filter restricts airflow and can cause the furnace to cycle off and on frequently. Clean or replace it as needed.
- Unusual Noises? Identify the source of the noise. Rattling sounds may indicate loose components, while squeaking could suggest worn-out bearings.
- Error Codes? Refer to the furnace’s manual for specific error codes. They provide vital clues about the issue.
- Pilot Light Issues? For gas furnaces, ensure the pilot light is consistently lit. If it keeps going out, there might be an issue with the thermocouple or the gas supply.
By following these steps and tips, you can efficiently reset your furnace and troubleshoot minor issues, ensuring your home stays warm and comfortable.
