Temperature control switch occurs in the use of air conditioners
Its temperature sensing pipe is placed on the plate of the outdoor heat exchanger.When the heat -making and outdoor heat exchanger cream layer is thickened, the temperature is lower than a set value.The contact action of the frost controller.
To check the frost temperature controller, the first is to place the temperature sensing part in the corresponding temperature water orTamper-proof Thermostat air.Use a multimeter to measure whether the two -wiring terminals are disconnected or turned on.You can know good or bad.The frost temperature controller is a component specially set in the hot air -conditioner control circuit to switch the electromagnetic replacement valve.
When the air -conditioning temperature controller fails, we must check the overcurrent, overcapitation protector startup, relay and capacitors of the compressor. We must also check the control and execution components in the electrical control system, and the temperature control main control selection switch.The following is the method of checking the frost temperature controller.Discovers the electromagnetic direction valve.The original heating cycle becomes the cooling cycle heating dual metal sheet temperature controller for indoor anti -cooling air control.
