Why does Konka heater have cold air?

The possible reasons for cold air in Konka heater are as follows:

The temperature in the heater is too high. When the warm air works for a period of time, the internal temperature is too high due to poor ventilation or abnormal heating elements, and the internal temperature control will automatically jump off and cut off the power supply of the heating elements, so that the hot air of the heater becomes cold air.

2. Abnormal heater temperature control. The temperature control sensitivity of air heater is too high. When the air heater is slightly heated during operation, the temperature control will jump off and cut off the power supply of the heating element.

3. The switch setting is incorrect. The switch position of the heater is not really set to the hot air position, or the button is not turned to the predetermined position.

4. The heating wire is short-circuited.

5. The 5.PC ceramic heater is broken.

6. The water temperature in the heater water tank is low and does not reach the corresponding temperature.
