Block sensor 3 failed

Blcok 3 sensor has failed, either open or short circuit. Another possibility is condensation in the block if it has been run for long periods at 4C. I can repair the block with new sensors and adjust/calibrate the block.

Hello friend, thanks for your information, although we had already found the fault, I must tell you that you are right, one of the wires of sensor 3 was broken, so since we did not have a new one for replacement, we soldered the broken wire and put a bit of  gray silicone super gray in the joint or union and with that it worked very well.  Thank you very much and greetings!!

We're hitting this now. Could you post a picture of your repair for comparison?
