First, check whether the "heating wire" is damaged or whether the "thermostat" is damaged. Generally, the "thermostat" is broken, so buy a "thermostat" to replace it.
Please don't heat it after power on, and the indicator light won't light up. The failure is generally caused by the lack of electric heating tube circuit in the power supply. During maintenance, the multimeter R× 10 can be used to measure the resistance at both ends of the three-core plug L and N on the base power cord.
The induction switch is caused by the combustion of the thermostat assembly. Must be replaced. You can buy it at the local electronic market or go to the maintenance department, and they will fix it for you.
Inductive switches mainly include infrared inductive switch, microwave inductive switch, ultrasonic inductive switch, piezoelectric inductive switch, electromagnetic inductive switch and capacitive inductive switch.
The human infrared intelligent induction switch is a switch that automatically starts when someone detects an area through an infrared sensor. The main device of human infrared induction switch is human pyroelectric infrared sensor.
Human pyroelectric infrared sensor: The human body temperature is constant, generally around 37℃, so it will emit infrared rays with a specific wavelength of about 10m. The working principle of passive infrared probe is to detect the infrared rays of about 10m emitted by human body.
Functional features:
1, an automatic control product based on infrared technology. People don't leave, in the activity, the switch continues to guide; After people leave, the switch will automatically turn off the load after a delay. People turn on the lights and turn off the lights, which is friendly, convenient, safe and energy-saving.
2. Zero-crossing detection function: contactless electronic switch to prolong the service life of the load.
3, the application of photosensitive control, switch automatic measurement, light intensity is not induced.
