I have a temp sensor that has suddenly started reading 20 degrees off the actual ambient temperature in my 379fl. If I heat the sensor with a hair dryer, I can show an indicated increase in room temp, but it immediately reverts to an indicated temp much lower than actual. Using a thermal temperature scanner, the actual room temp recently was 75. The indicated interior temp was 54, and I was unable to engage the front cooling system.

Anyone else having an issue like this?
