Why Does My Heater Keep Tripping the Circuit Breaker?
Here in the Phoenix area, an AC that causes a circuit breaker to trip isn’t a big surprise. Just think of how much work your air conditioner does during even one of the milder hot months of the year. Any electrical appliance that starts to strain when it works can put the extra demand on the circuit that causes a breaker to trip.
Speaking of which, you’ll probably need your AC to take on some work during this winter. If it’s giving you trouble, we’re ready to help with air conditioning repair in Tempe, AZ.
However, if your heating system—which doesn’t put in as much work as the AC—starts to trip circuit breakers, it might be a bit confusing. Why is this happening?
First, an important word about gas furnaces
Yes, a gas furnace can cause a circuit breaker to trip! It’s a common misunderstanding that natural gas furnaces do not require any electrical power to operate. The truth is that gas furnaces have vital electrical components necessary for them to run, such as the motor that powers the blower. And most modern gas furnaces use electrical ignition system to light their burners. If you’re having problems with a tripped breaker when the gas furnace is running, it’s possible the furnace is the cause.
Never attempt to work on a gas furnace yourself! Always call our furnace experts for repairs in Scottsdale, AZ.
Check the air filter to see if it’s clogged
One of the reasons that a forced-air heating system like a furnace or heat pump might trip a circuit breaker is because its air filter is clogged up. When the filter doesn’t allow air to easily pass through because of dust and dirt congesting it, it will cause the blower in the HVAC system to strain—and subsequently overload the circuit. Change a clogged filter for a fresh one, and continue to regularly change the filter every 1 to 3 months.
What else might be wrong?
If you find that the air filter isn’t the source of the issue, we recommend checking on the vents around the house. Accidentally blocked vents (probably from moved furniture) or ones that have been closed off will also heighten strain on the blower, triggering a tripped breaker.
If you still can’t find a reason for the problem with the circuit breaker and the heater, it’s time to call our technicians. You may have a mechanical malfunction in the heat pump or furnace, or the trouble might be air leaks in the ducts. Either situation requires our professional help, either heating repair or ductwork repair.
