Possible Causes
Failing blower or condenser fan motor, Overheating contactor or wiring, Debris on electric heat strips (in air handler), Shorted capacitor or board component
How to Fix / Troubleshooting
Safety first: Immediately turn off power at the breaker and disconnect if you smell burning. Do not continue to operate the unit.
- Step 1 – Visual inspection: After power is off and components have cooled, inspect the Ruud indoor and outdoor units for burnt wires, melted insulation, or scorched boards.
- Step 2 – Check motors: Smell near blower and condenser fan motors. If odor is strongest there and the motor housing is discolored, the motor may be failing.
- Step 3 – Electric heat strips: In air handlers with auxiliary heat, dust on heat strips can burn off at first use. This should dissipate quickly; persistent burning smell indicates a problem.
- Step 4 – Do not ignore: If any component shows signs of overheating, have a technician replace it and verify proper amperage and wiring.
