Does anyone have a Cruisair SMX II control panel that I could borrow to test to see if mine is bad? I will be happy to remove it from your boat and replace it within 5 minutes of testing (plus drive time). I just want to see if a new control panel will resolve my issue.
Basically mine is stuck on 72 and in heat mode and the fan is on full. I can't get it to do anything else and at $235+ I sure don't want to buy a new one if that not be the problem.
