Abstract
Description
technical field
[0001] The invention relates to the field of refrigerator control, in particular to a method and device for treating failure of a refrigerator probe. Background technique
[0002] figure 1 It is the detection circuit of the conventional refrigerator probe, and the resistance signal of the probe is converted into a voltage signal by connecting one or more resistors in series, and input to the A / D port of the single-chip microcomputer. The temperature probe is a device used to collect the actual temperature in the refrigerator. Generally, a room should have at least one temperature probe, which is one of the most important devices in the normal operation of the refrigerator.
[0003] However, the following reasons may lead to the failure of the probe: 1. The sensor connecting wire is prone to cracks under low temperature for a long time in a cold and hot cycle environment. If cracks occur, the moisture will penetrate into the temperature sensing element along ...
