Common Faults of Electric Heaters and Their Solutions
Common malfunctions:
1. The electric heater cannot be heated (the electric heating wire inside the electric heater is burnt or the connection box is disconnected).
2. The electric heating tube of the electric heater is cracked or broken (the electric heating tube is cracked, the electric heating tube is corroded and broken, etc.).
3. Air heater: electric heater leakage (mainly the automatic circuit breaker or leakage protection switch trips, the electric heating tube cannot be heated), usually the failure of this situation accounts for more than 90% of the electric heater failure.
Troubleshooting method:
1. If the electric heater cannot heat, and the internal wire of the electric heating tube is broken, it can only be replaced if it cannot be repaired; if the circuit or joint is broken or loose, it can be reconnected.
2. If the electric heating tube is broken or broken, only 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, you may need to replace the electric heating tube; if the junction box enters water, use a hot air gun to dry; if the wire is broken, it can be wrapped or replaced with tape electric wire.
