TRANE XE-80 furnace on OVERDRIVE Help !
I have a TRANE XE-80 furnace. Recently while using the airconditioning, I've noticed that I can hear the airconditioning. I went down into my basement and it is really loud down there.
The best way that I can describe it, is that the blower is on overdrive. It is running faster than I have ever heard it run before. I don't know the name of the part, but there is a cylinder inside of sheet metal enclosure that I believe is like a fan blade. It is that piece that is going really fast.
If I turn the thermostat off and on again, it is like it resets and everything is normal again for a few minutes and then it kicks back into overdrive again.
Everything seems to be working properly except it is super loud and going really fast. When I look at the electronics on the outside of the housing there is a red LED that is blinking, it may always do that, I don't know.
I am a DIYer but I don't know much about this unit or any HVAC for that matter. Does anyone know what might be wrong ?
