Top Heating Troubleshooting Questions

Here are common furnace and heating system questions homeowners can safely check before scheduling service.

Where is the furnace power switch located, and what should I look for in the circuit breaker panel?

The furnace power switch is located on the side of the furnace cabinet itself. It looks like a single light-style switch. On the circuit breaker panel you should see a single pole breaker labeled “furnace”.

Can a dirty filter cause my furnace to shut down completely?

Yes – a very dirty or clogged air filter absolutely can cause a furnace to shut down completely. It can also make the furnace run longer and potentially shorten the blower life.

How do I know if my pilot light is out or if the electronic igniter is broken?

If you see no flame or a weak yellow flame through the viewing window.

Could snow or ice be blocking my furnace exhaust vent on the roof or side of the house?

Yes, absolutely; snow and ice can easily block your furnace’s exhaust vent, especially with modern high-efficiency units that vent out the side of the house, which can stop your furnace from working and create a serious carbon monoxide (CO) hazard by trapping dangerous gases inside.

How do I prevent my pipes from freezing while I wait for a furnace repairman?

To prevent frozen pipes while waiting for furnace repair, keep your thermostat above 55°F, let faucets drip slowly (especially on exterior walls), open cabinet doors under sinks, insulate exposed pipes with foam or heat tape, and use alternative heat sources like electric space heaters cautiously in occupied areas to keep pipes warm and water moving.

Is it safe to use my oven for heat, or how many space heaters can I run on one circuit?

No, you should never use your oven for heat due to severe risks of fire and carbon monoxide poisoning. Space heaters can be a safer alternative, but typically only one space heater should be run on a single circuit to avoid overloading the electrical system.

Why is my furnace constantly cycling (turning on and off) in negative temperatures?

Your furnace is likely short cycling (turning on and off rapidly) in negative temperatures due to safety shutdowns from overheating, often caused by restricted airflow (dirty filter, closed vents) or a faulty flame sensor, or by an oversized furnace heating too fast and the thermostat shutting it off prematurely, all made worse as the system struggles in extreme cold to keep up.

What does a (specific color) blinking light on my furnace mean?

A blinking furnace light uses a color and flash pattern (like Morse code) to signal system status or errors, with green often meaning normal operation/power, yellow/amber indicating normal heating/flame presence, and a blinking red usually pointing to a specific fault like ignition failure, overheating (dirty filter/vents), or pressure switch issues that require checking the manual and potentially calling a pro.

If these steps don’t resolve the issue, our technicians can help diagnose the problem quickly and safely — and restore comfort to your home.
