Q: Heating Tube Not Heating or Low Heating Efficiency

Possible Causes:

• Power supply not connected or insufficient voltage.

• Internal resistance wire broken or aged.

• Loose or oxidized wiring terminals.

• Scaling or carbon buildup (in liquid heating applications).

Solutions:

• Check if the power supply and voltage are normal.

• Measure resistance with a multimeter; if the reading is infinite, replace the heating tube.

• Clean the terminals to ensure good contact.

• Regularly descale (using citric acid or specialized cleaning agents).
