Burning or electrical smell coming from the refrigerator, with or without visible smoke.

Safety first: Immediately unplug the refrigerator or shut off the breaker if you smell burning or see smoke. Do not continue to operate the unit.

Step 1 – Visual inspection

• After the unit has cooled, remove the rear access panel and inspect the condenser fan motor, compressor wiring, and control board area for burn marks or melted plastic.

Step 2 – Identify damaged parts

• Look for discolored connectors, charred components on the control board, or melted insulation.
• Do not attempt to repair burned wiring with tape alone; replace damaged harness sections.

Step 3 – Replace failed component

• If the condenser fan motor is burnt or seized, replace it.
• If the main control board shows burn damage, it must be replaced.

When to call a professional: Electrical burning smells indicate a serious fault. A Sub‑Zero technician should inspect and repair the unit before it is used again.
