Common faults of electric heater:

The electric heater cannot be heated (the electric heating wire inside the electric heater is burnt out or the wire is broken at the junction box).

The electric heating tube of the electric heater is broken or broken (the electric heating pipe is cracked, the electric heating pipe is corroded and cracked, etc.).

Air heater

Electric heater leakage (mainly automatic circuit breaker or leakage protection switch trip, the electric heating tube can not be heated), usually this kind of fault accounts for more than 90% of the electric heater fault.

Troubleshooting of electric heater:

If the electric heater cannot be heated, and the internal wire of the electric heating tube is broken, it can only be replaced; if the circuit or connector is broken or loose, it can be reconnected.

If the electric heating tube is broken or broken, only replace the electric heating tube.

If it is leakage, it is necessary to confirm the leakage point according to the situation. If it is the electric heating tube itself, it can be baked in an oven; if the insulation resistance value cannot go up, it may be necessary to replace the electric heating tube; if the junction box is filled with water, blow dry with a hot air gun; if the wire skin is broken, wrap it with adhesive tape or replace the wire.
