How to Fix / Troubleshooting
Safety first: If you smell burning plastic or see smoke, unplug the freezer immediately and do not continue to operate it.
Steps:
- 1. Unplug and inspect: Remove the rear lower panel and inspect the compressor area, wiring, and control board for scorch marks or melted plastic.
- 2. Check start relay and overload: Look for discoloration or melting. Replace any damaged start components with RCA-compatible parts.
- 3. Clean condenser: If the smell is more like hot dust and occurs after long disuse, clean the condenser coils and fan area thoroughly.
- 4. Control board check: Inspect the main control board for burnt components. If found, the board must be replaced.
- 5. Test cautiously: After addressing visible issues, plug the unit in and monitor closely. If the smell returns, unplug and call a technician.
Warning: Do not ignore burning smells; they can indicate a fire hazard.
