Why is the outlet temperature of the electric heater abnormal/the temperature cannot reach the required temperature?
Temperature controller failure, electric heating tube failure, control circuit failure, insufficient air volume or low air pressure inside the heater body, cooling fan damage, etc.
Why does the electric heater fail to heat?
The heating wire is burned out, the internal junction box or external line is broken or loose, the power supply phase is missing, the electric control board is damaged, etc.
Why does abnormal heating occur (overheating or no heating)
Improper design: Exceeding the maximum operating length of the heating cable results in excessive voltage drop and insufficient power. Overlapping heating: Overlapping parallel heating cables, if not self-limiting, can cause burnout due to the combined heat. Insulation issues: Lack of insulation, thin or uneven insulation, leading to heat loss and prolonged operation of the heating cable in low or humid conditions, affecting its efficiency and lifespan.
Causes of short circuits/open circuits
Installation damage: Repeated bending, dragging, or excessive flexing of the heating cable during installation can damage its insulation. Wiring issues: Improper installation of wiring accessories can damage waterproof seals, allowing moisture or corrosive substances to enter and cause short circuits or leakage. External physical damage: Activities such as pipeline maintenance, cross-operation, and equipment lifting can cause physical damage to the heating cable.
