Furnace Tripping the Breaker
in Columbus, GA
When your furnace trips the breaker once, it might be a fluke. When it happens again and again, something in the system is pulling too much current. Columbus homes in the Weracoba-Cherokee area and other older neighborhoods often have 15-amp furnace circuits that cannot handle a struggling blower motor. Resetting the breaker over and over without fixing the cause will eventually damage the motor or start a fire.
Quick Answer
A furnace that trips the breaker repeatedly has an electrical problem, not just a nuisance. It usually means the blower motor or control board is drawing more current than the circuit can handle. On Columbus homes built before 1995, the electrical panels are often undersized for modern HVAC loads. Call (762) 275-8579 to get the motor and wiring inspected before you lose heat entirely.
Telltale Signs
Warning Signs to Watch For
- The furnace stops running and you find the breaker in the tripped position
- The breaker trips within minutes of resetting it and restarting the furnace
- The furnace works fine for a few days, then trips the breaker again
- The breaker feels warm or hot when you check the panel
- The furnace runs but the blower sounds labored or slower than normal before the trip
Root Causes
What Causes Furnace Tripping the Breaker?
Failing Blower Motor
A blower motor with worn bearings or damaged windings draws far more current than a healthy motor. Over time, the extra current load trips the breaker. This gets worse in winter when the motor runs for long stretches and the extra heat from heavy use accelerates the failure.
The Fix
Blower Motor Replacement
The old motor is removed and a matched replacement is installed. The technician checks that the new motor draws correct amperage before finishing.
Undersized or Failing Breaker
Breakers in Columbus homes built in the 1970s and 1980s were sized for the equipment that existed then. A replacement furnace with a larger motor can exceed the original circuit rating. Breakers also weaken after years of trips and may no longer hold their rated current.
The Fix
Circuit Upgrade or Breaker Replacement
An electrician or HVAC technician evaluates the circuit load against the furnace specifications. The breaker is replaced or the circuit is upgraded to match the actual current demand of the equipment.
