Symptoms Of A Bad Furnace Transformer

No Heat

When you turn on or raise the temperature, your furnace should immediately turn on and produce heated air. But, if your furnace’s transformer is faulty, it may not be able to produce hot air. A completely malfunctioning transformer will not supply power, and the furnace will not turn on.

Loud Or Strange Noises

A soft humming sound is normal for a functioning furnace. However, if you hear a loud noise of any kind, including humming, clacking, raddling, or clicking, your furnace is likely malfunctioning. If this occurs, turn off the unit to avoid further damage and contact one of our reliable furnace technicians for inspection and repair.

Circuit Breaker Tripping

A circuit breaker trips when voltage surges and clearly indicates a malfunctioning transformer. The more faulty transformer, the more often the circuit breaker will trip. This is not good for the furnace as a whole, and if you are experiencing this issue, it's important to contact one of our technicians to see if the transformer will need to be replaced.
