Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately turn OFF and unplug the unit if you smell burning or see smoke. Do not continue to operate until inspected.
- Step 1 – Initial use consideration: A slight odor may be normal during the first few hours of use as manufacturing residues burn off. However, strong or persistent burning smells are not normal.
- Step 2 – Inspect wiring and components: Remove the cover and look for discolored, melted, or burnt wires and connectors. Pay special attention to the fan motor, compressor terminals, and control board.
- Step 3 – Check fan motor: If the smell is strongest near the fan motor and it is very hot to the touch, replace the motor assembly.
- Step 4 – Examine control board: Look for burnt spots or swollen components on the PCB. Replace the board if damaged.
- Step 5 – Do not operate until repaired: Operating with burnt components is a fire hazard. Replace all damaged parts before using the unit again.
If you are not comfortable inspecting electrical components, have a qualified technician evaluate the unit.
