Air dry burning heating tube general problems

- May 30, 2019-

1. Leakage (the phenomenon is that the automatic circuit breaker or leakage protection switch trips, the electric heating tube can not be heated), accounting for more than 90% of the heater failure

2. Power-on and no heating reaction (whether the electrode part is detached or the contact is bad or the terminal box is broken)

3. There are obvious cracks on the surface of the ceramic tube (electric heating tube crack, tungsten alloy heating wire is broken by large current, etc.)
