Troubleshooting a home furnace

Understand Your Heating System

Before you can start troubleshooting your furnace, you have to understand how it works. Your central heating system is composed of a network of ducts and vents that’s connected to an airflow fan. This system is controlled by a thermostat, which can be programmed to turn on and shut off automatically, thus regulating your home’s ambient temperature based on a desired temperature setting.

Check for a Viable Power Supply

If your furnace doesn’t turn on when it’s supposed, or if it suddenly shuts off, check to see that your system is receiving power. In some instances, your HVAC system’s circuit breaker may have been tripped, which happens when there’s a power outage or a power surge. Also, check your thermostat if it’s connected to your home’s electrical panel. If the breakers have been tripped, reset them to restore power to your furnace.

Check Your Thermostat

Your system’s thermostat relies on sensors to regulate the ambient temperature of a room. If the sensor or thermostat malfunctions, your furnace could run continuously, causing your monthly utility bills to skyrocket. Refer to your thermostat’s user manual for troubleshooting advice.

Make Sure Your Furnace’s Pilot Light Is On

Older furnaces have pilot lights, which may go out. If your unit is running but is not heating, or if you smell gas, make sure your pilot light is lit—in the case of gas, don’t light your furnace until after you’ve shut of your furnace and have aired out your home. If your furnace is newer, inspect its electronic ignition mechanisms. Refer to your furnace’s user manual.
