Common faults of electric heaters:
The electric heater does not heat up (the heating wire inside the electric heater is blown or the wire is broken at the junction box).
The electric heating pipe of the electric heater is cracked or broken (electric heating pipe crack, electric heating pipe is corroded and cracked, etc.).
Air heater
Electric heater leakage (mainly automatic circuit breaker or leakage protection switch tripped, electric heating pipe can not heat), usually this fault accounts for more than 90% of electric heater failures.
How to deal with electric heater failure:
If the electric heater cannot be heated, and the internal wiring of the electric heating tube is broken, it can only be replaced; If the line or connector is broken or loose, it can be reconnected.
If the electric heating pipe is broken or broken, then only replace the electric heating pipe.
If it is a leakage, it is necessary to confirm the leakage point and consider it according to the situation. If it is the electric heating tube itself, it can be baked in the oven; If the insulation resistance value does not go up, the electric heating pipe may have to be replaced; If the junction box enters the water and dries it with a heat gun; If the wire is broken, it can be wrapped with adhesive tape or replaced with the wire.
