Handheld testing device used for testing of refrigerator electric control board and testing method

Abstract

The invention relates to a handheld testing device used for testing of a refrigerator electric control board and a testing method. The handheld testing device is in direct communication with the refrigerator electric control board; the corresponding forced load working mode of the handheld testing device is set according to the fault phenomenon of the whole machine, then a corresponding control instruction and a corresponding code are generated, the control instruction is sent to the refrigerator electric control board, and the refrigerator electric control board controls corresponding loads to work independently and feeds back the operation situations of the corresponding loads; when starting of the corresponding loads fails, it is judged that the electric control board has a fault; when starting of the corresponding loads succeeds, an output port of the corresponding loads of the refrigerator electric control board is tested according to the displayed corresponding code, and whether the electric control board has a fault or not is judged. The after-sale repair convenience and accuracy are improved; the repairing frequency is reduced; the after-sale repair expenses of users are reduced; the market reject ratio of electric control boards is reduced; the brand credibility is improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a hand-held detection device and a detection method for detecting electric control boards of refrigerators. Background technique [0002] At present, in the after-sales maintenance of refrigerators, especially for the electric control board of the refrigerator, there is no specific maintenance method, and it is impossible to judge whether the electric control board is normal. Usually, after the whole machine has a problem, only the electric control board is replaced, and the root cause of the whole machine failure cannot be found. . As a result, the problem still appeared in the later period, and the root cause was not found. This has resulted in an increase in the defect rate of electrical controls and the user's distrust of refrigerator brands. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-held dete...

[0002] At present, in the after-sales maintenance of refrigerators, especially for the electric control board of the refrigerator, there is no specific maintenance method, and it is impossible to judge whether the electric control board is normal. Usually, after the whole machine has a problem, only the electric control board is replaced, and the root cause of the whole machine failure cannot be found.

The problem still occurs in the later period, and the root cause has not been found

This has resulted in an increase in the defect rate of electrical controls and users' distrust of refrigerator brands
