Main fault problems and solutions of electric heating tubes

The damage of electric heating tubes mainly includes:

1. Leakage (the phenomenon is that the automatic circuit breaker or leakage protection switch trips, and the electric heating tube cannot heat), accounting for more than 90% of heater failures

2. No heating (internal heating wire burns out or the wire is broken at the junction box)

3. The electric heating tube is broken or fractured (cracks in the electric heating tube, corrosion and fracture of the electric heating tube, etc.)

Handling methods:

1. For leakage, confirm the leakage point. If it is the electric heating tube itself, you can use an oven to bake it. If the insulation resistance value cannot be increased, you may need to replace the electric heating tube. If the junction box is flooded, use a hot air gun to blow it dry. If the wire is broken, wrap it with tape or replace the wire.

2. If the electric heating tube is heated, if the wire is broken inside the electric heating tube, it cannot be repaired and can only be replaced; if the line or connector is disconnected or loose, reconnect it.

3. For the rupture or fracture of the electric heating tube, it can only be replaced.
