I need a little help. One of my fan timers is stuck in manual mode, everytime I change it to auto it goes back to manual. I've tried moving the timer to different outlets in both a dc8 and dc4hd but the result is the same. The program turns the fan on and off based on the temp and controls a 6" fan in the sump. It was working fine for a while, last week my temp probe went bad and now I have a new one. Any ideas?
