Chemical or burning plastic smell when the unit is running.

Safety first: If you smell burning plastic or see smoke, unplug the unit immediately and do not continue to operate it.

Steps to investigate:

• Initial use: A slight odor during the first few hours of operation can be normal as manufacturing residues burn off. This should dissipate quickly.
• Inspect rear components: With the unit unplugged, remove the rear panel and look for discolored, melted, or burnt wiring, connectors, or components on the main PCB and compressor start relay.
• Replace damaged parts: Replace any burned compressor start relay, wiring harness sections, or control board with compatible BODEGA parts.

When to call a professional: Electrical burning smells indicate a potential fire hazard; have a qualified technician inspect and repair the unit.
