measure the compressor inlet voltage to diagnose the display cooler fault
Measure the voltage between the power inlet and the overload protection terminal. If there is an AC 220V voltage, the display cooler fault is in the compressor and its accessories ; If there is no AC 220V voltage, it means that the fault lies in the temperature controller and other parts of the power supply circuit.
measure resistance to diagnose faults
①Measure the display cooler power plug resistance: roughly understand the compressor circuit connection, if the resistance is small, the compressor power supply circuit is connected; if the resistance is large or infinite, the compressor power supply circuit is Break.
②Measure the resistance of the compressor terminal and the casing: understand the display cooler leakage, it should be infinite under normal conditions, if there is a resistance value, it means that the compressor or a device has a net leakage of electricity.
③Measure the resistance between the terminals of the device to diagnose whether it is good or bad: the resistance between the incoming wire of the thermostat and the on-off point should be turned on at normal temperature and turned off at low temperature; the resistance of overload protector and PTC starter is very small, high temperature The bottom should be disconnected or high impedance.
