Ran diagnostics, AFS code came up - air flow switch. So, I open up the case to see what I can see, and I find duct tape across the air intake. Would this have been done as part of closing routine, and they just forgot to remove it? It looks relatively fresh, and the heater is 3 years old, so its definitley not original. I can't imagine it would run like this - and that this is the problem - any thoughts?
Thanks,
John
