A burning or musty smell from an RCA refrigerator most often comes from a simple source you can check quickly. First, make sure the interior light is not staying on when the door is closed, since an incandescent bulb left lit can get hot and smell burnt. If the smell comes from the back near the compressor, the start relay or overload kit may be failing and preventing the compressor from starting, which can also leave you with a fridge not cooling or a refrigerator not getting cold. Next check the power cord and wall receptacle for burn marks or a loose fit. If the odor seems to come from the exterior or bottom, inspect the condenser fan motor and its wiring for overheating or burned connections. Pinched or shorted wire connectors and, less commonly, a failed control board can also produce burning smells.

The compressor start device, also known as a start relay or start relay and overload kit, may have failed. This will usually cause the compressor to not start. If the burning smell is coming from the compresser area check the start device. If the start device smells burnt, or the compressor is trying to start but can't, the start device is likely bad and will need to be replaced.
Inspect the power cord prongs and wall receptacle for burn marks. The cord should plug tightly into the receptacle. A power cord that is hot is a sign of a bad connection. If the power cord is burnt or damaged it will need to be replaced. If the cord is loose in the receptacle, the receptacle will need to be replaced by a licensed electrician.
If the burning smell appears to be coming from the exterior of the refrigerator, it's possible the condenser fan motor is wearing out or overheating. You should inspect the component for any burn marks, especially near the wire connection points, and use a multimeter to test the motor for electrical continuity to help determine if the component has burned out.
