The issue may be due to a non-working power socket, a faulty switch, or a malfunctioning heating element. The troubleshooting steps are: first, check if the socket is properly powered and if the power plug is loose; second, check if the switch indicator light or illumination light is lit when powered. If the above two items are normal, it may be a heating element fault; if the socket is properly powered and the switch indicator light or illumination light is not lit, it may be a switch fault.
The issue may be caused by directly heating cold food from the refrigerator or using it in an open extremely cold environment. It is recommended not to directly heat cold food; instead, fry or heat the cold food first before insulation. It is also not recommended to use it in extremely cold environments.
The issue may be due to a burnt-out heating or illumination light. The troubleshooting steps are to check if the power plug is loose and whether the heating tube is properly powered and heating. If the above two items are normal, it may be a fault with the heating or illumination light.

The issue may be due to a short circuit. The troubleshooting steps involve opening the device to check if the internal wiring is disconnected or if the wiring terminals are burnt, causing internal wiring to connect with the metal casing, resulting in a short circuit.
The issue may be due to the thermostat being set too high, causing excessive steam. It is recommended to set the appropriate temperature based on the characteristics of the food.
