Unit trips household circuit breaker or GFCI when turned on or when heater engages.

Safety first: Do not repeatedly reset a breaker that trips. Unplug the unit and leave it unplugged until inspected.

• Step 1 – Visual inspection: Remove the housing and inspect wiring around the heating element and fan motor for pinched or bare wires touching metal.
• Step 2 – Check element: Look for cracks or breaks in the heating element where it may contact the metal cavity. Replace the upper heating element assembly if damaged.
• Step 3 – Dry moisture: If the unit was recently cleaned heavily, allow it to dry for 24 hours in a warm, dry place before retesting.
• Step 4 – Cord inspection: Replace the power cord set if there is any sign of damage or if flexing the cord causes tripping.
• Step 5 – Professional testing: If no obvious fault is found, have a technician perform insulation resistance tests to locate the ground fault.
