I have a Pentair Minimax NT with error code E04 and unit will turn on blower will start then you here the ignition for the igniter. It fires either for a few seconds or a minute or two then shuts down and the error message comes on.
If you have the extra cash and can make it work just buy a new heater!! Supposedly this was a bad design and you really never know what the E04 is coding for and that comes right from the warranty service reps mouth. He is service rep for several of the major names and recommended the Hayward H Series it has a Standard Cupro Nickel Heat exchanger which has excellent corrosion resistance over most other models. $1604.99 delivered to my door From Amazon!!I am having the same issue with my Minimax NT. Fan comes on igniter fires and flames start for a second then go off. Please keep us posted with any resolution.
I am having the same problem. Fan turn on, heat come on, then a minute later it shuts off with the same error codes (on the panel and internally). I changed the flame sensor and the temp probe. I bypassed the air flow switch. Still have the same problem. Any new thoughts or ideas?gklein: did you ever resolve your Minimax NT fan issue? I am havingthe same problem today.
