Description

Four-in-one inverter refrigerator detector

The four-in-one inverter refrigerator detector is a small size, light weight, full-featured, and easy-to-carry maintenance tool developed for home appliance after-sales maintenance masters. It can effectively improve maintenance efficiency and reduce misjudgment.

First, the detector can directly start the inverter refrigerator compressor (refrigerator inverter compressor can be)

Second, the detector can directly drive the refrigerator inverter board

3. The detector can directly judge the quality of the bistable pulse valve

Fourth, the new model is to manually adjust the operating frequency of the compressor.

Instructions:

Frequency conversion board detection: connect the detection line of the frequency conversion board of the detector to the communication interface of the frequency conversion board of the refrigerator (make sure that the frequency conversion board has 220v power supply before testing), the detector automatically matches the parameters of the frequency conversion board, and the compressor can be started directly after matching correctly. If the compressor starts, it can be judged that the compressor and the inverter board are normal. If it does not start after 3 tests, please use the compressor test function to test the compressor. (Note that once the compressor is started, it will take 3-5 minutes to test again, and the test will be performed after the system pressure is balanced.)

Inverter compressor detection; connect the detector compressor detection line to the refrigerator compressor, press the compressor detection button for 30 seconds, the detector automatically matches the compressor parameters, and the compressor can be started directly after the matching is correct. If the test does not start, it can be judged that the compressor is faulty. (Note that once the compressor is started, it will take 3-5 minutes to test again, and the test will be performed after the system pressure is balanced.)

Pulse solenoid valve detection; connect the solenoid valve detection line of the detector to the solenoid valve interface, press the solenoid valve detection red and green buttons respectively, and detect the solenoid valve twice to determine whether it is good or bad. (Note that the detector outputs DC220 pulse voltage, do not touch it during use. After power-on, the output end is prohibited from short-circuiting to avoid burning the detector. Before measuring, please use a multimeter to check whether the solenoid valve is short-circuited to avoid burning the detector.)
