Dehumidifier emits a burning or electrical smell when running.

Safety: Immediately unplug the unit. Do not continue to operate a dehumidifier that smells like burning plastic or wiring.

Steps:

• Visual inspection: After the unit cools, remove the cover and inspect the fan motor, compressor terminals, and control board for burn marks or melted insulation.
• Check fan motor: If the smell is strongest near the fan and the motor is hot to the touch, replace the fan motor assembly.
• Inspect wiring: Tighten any loose connections and replace any discolored or charred wires using proper connectors.
• Control board: If components on the PCB are visibly burnt or cracked, replace the main control board.

Warning: If you cannot identify the source of the smell, have the unit inspected by a qualified technician before reuse.
