Is your intake anywhere close to the exhaust?

 

[Twowaxhack]

Does it have an intake filter or condensation drain ?

check those for function if it has it.

Is the wind getting to the exhaust causing back pressure. It has been pretty windy in Michigan the last few days. I am not sure about your area

Could the wind be causing that? We installed it Saturday and it was fine no errors what so ever, we got a storm Sunday and Monday

I have seen wind cause a back pressure build up issue. I am not sure if this is your case but i know it has happen. I have also seen one where leaves blew into the exhaust and snow drift.
