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
 
update, sorry to waste your time - that was the problem. I should have known. But, in my defense, the pool guy who opens and closes my pool was ready to charge me $200 to come look at it - when HE WAS THE ONE WHO PUT IT ON! When my wife sent him a picture of it he then remembers - oh yeah, we put that on the keep mice out of the blower. Great.
