How to Fix / Troubleshooting

Safety: Immediately unplug the unit if you smell burning. Do not continue to operate until inspected.

Steps to investigate:

Visual inspection: After the unit cools, remove the cover and inspect wiring, motor, and capacitor for burn marks or melted insulation.
Check fan motor: Spin the fan blade by hand; it should move freely. A stiff or seized motor can overheat and smell.
Inspect capacitor: Look for bulging or leaking capacitors. Replace if damaged.
Tighten connections: Check all spade terminals and wire nuts for tightness. Replace any discolored connectors.
Do not ignore: If you cannot locate the source or the smell returns, discontinue use and contact a technician.
