Common faults of electric heaters:
1. Unable to heat (the heating wire inside the electric heater is burned out or the connection box is disconnected)
2. The electric heating tube is cracked or broken (the electric heating tube is cracked, the electric heating tube is corroded and broken, etc.)
3. Leakage (mainly the automatic circuit breaker or leakage protection switch trips, the electric heating tube cannot be heated), usually the fault in this case accounts for more than 90% of the electric heater failure
Handling method of electric heater failure:
1. If the heater fails to heat and the internal wire of the electric heating tube is broken and cannot be repaired, it can only be replaced; if the wire or connector is broken or loose, it can be reconnected.
2. If the electric heating tube is broken or broken, the only way to replace the electric heating tube.
3. 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 an oven; if the insulation resistance does not go up, then the electric heating tube may be replaced; if the junction box is filled with water, use a hot air gun to dry; wire.
