Haier Refrigerator has a bad smell or burning smell
If your Haier refrigerator smells like something is burning, act quickly but stay calm. Start by checking the light bulb, since an incandescent left on or shorted in the socket can get hot and produce a burning odor. Next inspect the compressor start device or start relay; a failed start device will usually prevent the compressor from starting and is a common cause of a refrigerator not cooling or a fridge not cooling. Check the power cord and wall receptacle for burn marks or a loose fit, because a hot plug or damaged cord is a frequent, fixable source. If the smell seems to come from the outside cabinet, look at the condenser fan motor for overheating or burned wiring. Also inspect nearby wire connectors for pinched or shorted wires, and consider the control board if a fan is stuck or electronics look scorched.

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.
