Hi, Ive replaced a ribbon cable to a heating element with a thermistor. The cable was damaged but everything worked before I soldered in the new cable. The cable does a lot of moving so I thought it would be a good idea to put all purpose silicon where the cable goes into the board so it doesnt bend at the board where it might break off. I now get an error code for temp sensor short circuit though and a temp reading of 120degC when it should be about 25. Could there be current leak because of the silicon?

 

Most likely not.

 

If it were Silicon, it would cause a leak.

If it is Silicone, then likely not, although as Silicone cures, it puts out Acetic Acid (smells like Vinegar), which is corrosive. Silicone Bath Caulk should not be used to pot electronics. There are some neutral-cure Silicones specifically designed for potting electronics.

 

What is the 25C resistance of the sensor?

I have a spare one that should be working that reads 11.2k ohm and the one im working with is 9.75k ohm..

wait I've just sat them beside each other for a while and the resistances are now 10.12k (problem one) and 10.88k (spare)

I soldered the ribbon cabled in upside down at one end.. hahaha
it should do a flip between boards. OK thanks everyone.. I'll leave now.
