Antminer S19j Pro ERROR_TEMP_TOO_HIGH - S19j Pro Kernel Log

According to the log provided by the miner user, the temperature of the hash board No.2 of the miner is ERROR_TEMP_TOO_HIGH (as shown in the figure below), which exceeds the maximum temperature that the hash board can withstand. This will cause miners to no longer read temperatures, cancel threads, and shut down hash boards.

Solution:

First, use the fixture to test the No.2 hash board. S19JPRO has 4 temperature sensors, and the test log will detect which one is faulty. (Note: The two temperature sensors at the air inlet are particularly easy to corrode. You must use plate-washing water to clean the temperature sensors and their associated resistors. If the component pins are found to be corrupted and damaged, replace them directly). After finding the faulty temperature sensor in the test log, find it corresponding to the hash board, and focus on checking its I2C serial bus power supply and VCC (normally 3.3V), and replace it directly if it is abnormal.
