MGEDGE2013 Posted January 11, 2023 Report Share Posted January 11, 2023 My HVAC system will turn itself on at times and the blower fan will change speeds from low to high as if I am pushing the controls. I can manually push the buttons back to low and it will click back through the speeds and go back to high in a few minutes... Ideas appreciated Quote Link to comment Share on other sites More sharing options...
bofus Posted January 12, 2023 Report Share Posted January 12, 2023 I've not had this in my Edge; BUT, I have had this happen in my Focus. It usually goes to max AC mode and always when I had the entire system off, I think. I've not had it change speeds when the system was already on. It happens pretty rarely and certainly with no input from me. I've no idea why. In the past 5 years, it probably happened maybe 4-5 times. No clue why and I didn't bother taking it in as I don't see how they could possibly troubleshoot it when I can't replicate it on demand. So, it's rare that the entire HVAC is off in the first place.
