Odor:
The rancid smell is looming. Finally, the cause of the investigation was the refrigerator.
Common places to check:
1. Sink: food residue. Solution: Buy a filter to prevent food residue from flowing into the sink
2. Bathroom: Hair and foreign objects block the drain pipe. Solution: buy decomposition liquid, dredge artifact
3. Refrigerator; reason: ( when the refrigerator is in a power failure state, the frozen meat will thaw, and the blood will shoot water to the water storage tank above the compressor through the water hole in the refrigerator, and the water will evaporate when the compressor is heating. Leaving some blood, dirt, will emit a foul smell, which is the reason for the looming smell)
Refrigerator inspection:
- Use a screwdriver to unscrew the bottom compressor protection plate, the water storage tank on the compressor is most prone to odor
- Check inside the compressor for rat nests
