What to check first
Can I keep using it?
Food safety first
You can usually keep it powered while checking temperatures, but food safety comes first if cooling is weak or power was interrupted.
- Safe next step
- Check actual compartment temperature, move perishable food to safe cold storage if needed, and use the model manual for any further steps.
- Stop when
- Food is thawing, temperatures are unsafe, the unit is not cooling, or electrical symptoms appear.
Electrical warning: stop and verify
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
