Troubleshooting your broken furnace before Autumn

For battery-operated thermostats, low battery levels can be the culprit behind furnace issues. Pay attention to any flashing "low battery" icon on the control screen. If you spot this warning, promptly replace the batteries to ensure seamless thermostat functionality.

Before diving deeper into furnace troubleshooting, ensure your furnace power switch is in the "on" position. This switch can be located on the side of the furnace or even on a wall-mounted switch. In some cases, a switch may have an associated fuse. Examine it closely for signs of blackening or burning. If you encounter any issues, consider hiring a licensed professional to address the situation.

If your furnace appears to have power but still isn't operating correctly, it's worth checking for tripped circuit breakers. Your electrical panel should ideally be labeled "Furnace" or "HVAC" for easy identification. If not, look for any breakers that have tripped and reset them if necessary. Keep in mind that while this may temporarily restore power, a tripped breaker or burnt fuse could indicate larger electrical issues that require professional evaluation.

Modern furnaces incorporate safety switches on their front panels to prevent engagement if the door isn't securely closed. Make sure the panel door is properly latched before proceeding. Consult your furnace's owner's manual for guidance if you're unsure about its proper closure.

For gas furnaces, a functional pilot light is essential for proper operation. The pilot ignition acts as a safety feature to prevent gas flow until there's a ready flame to ignite the burners. While relighting a pilot light can be potentially hazardous, it's recommended to seek professional assistance from a licensed technician for any adjustments within your furnace.

Dirty and clogged furnace filters are a common culprit behind furnace problems. Filters are designed to capture dust, hair, and particles, but when left unattended, they can obstruct proper airflow. If your furnace is running but warm air isn't circulating effectively, inspecting and replacing filters may be the solution.

If your furnace is operational but you're still experiencing a chilly home, it's worth examining your outflow vents and registers. Sometimes, they can be inadvertently closed or obstructed, especially those located in the floor. Ensure vents are open and unblocked, allowing warm air to circulate efficiently.

Not all furnaces vent through chimneys. Newer models often have side vents for fresh air intake and exhaust. These openings can sometimes get obstructed by snow, leaves, insects, or moisture, causing venting issues. In such cases, it's advisable to consult a licensed technician for expert advice on venting solutions tailored to your furnace setup.
