Check whether the "heating wire" or the "thermostat" is broken first. Generally, the thermostat is broken, so buy a thermostat and install it.
No heating after electrification, and the indicator light is not on. Faults are often caused by the power supply not being added to the electric heating tube circuit. When overhauling, you can first measure the resistance of L and N ends of the 3-core plug on the base power cord with a multimeter R× 10.
The induction switch is caused by the combustion of the thermostat assembly. You must replace a set of components, which are available in the local electronic market, or they can help you repair them when you go to the maintenance department.
Extended data:
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 passes through the infrared induction detection area. The main device of human infrared induction switch is human thermal discharge infrared sensor.
Human pyroelectric infrared sensor: The human body temperature is constant, generally at 37℃, so it will emit infrared rays with a specific wavelength of about10 μ m. The passive infrared probe works by detecting the infrared rays emitted by the human body.
Functional features:
1, an automatic control product based on infrared technology. People never leave, and the switch keeps turning on; After people leave, the switch will automatically turn off the load after a delay, and the lights will be on when people are away, which is friendly, convenient, safe and energy-saving.
2, with zero-crossing detection function: contactless electronic switch, extending the service life of the load.
3, the application of photosensitive control, automatic metering switch, no induction when the light is strong.
