Some faults may occur during the use of the electromagnetic heater. Here are several common faults and their solutions:

1. Uneven heating or inability to heat:

• The heater coil may be damaged and needs to be replaced.

• Check whether the power connection is loose or disconnected to ensure that the power supply is normal.

• Check whether the control system works normally and confirm that the temperature control setting is correct.

2. Heater does not start:

• Check whether the power connection is loose or disconnected to ensure that the power supply is normal.

• Check whether the controller or switch is damaged. It may be necessary to replace the controller or switch.

• Check whether the overload protector is triggered to ensure that it is not triggered or has been reset.

3. Abnormal noise from heater:

• Check whether the mechanical parts of the electromagnetic heater are loose. It is necessary to fasten or replace the damaged parts.

• Check whether there are foreign matters inside the electromagnetic heater, such as metal debris, which need to be cleaned.

4. The overheat protector is frequently triggered:

• Check whether the cooling system works normally to ensure good heat dissipation.

• Check whether the fan or radiator of the heater is blocked and need to be cleaned or replaced.

• Check whether the temperature sensor is damaged or installed in an inaccurate position, which may need to be repaired or reinstalled.

It should be noted that there may be more specific faults and solutions for specific models and brands of electromagnetic heaters. In case of failure, it is recommended to refer to the operation manual of the equipment or consult relevant manufacturers or professional technicians to obtain accurate fault diagnosis and solutions.
