I’ve finally figured it out why my heater, Pentair MiniMax NT, stopped working. It showed air pressure issue with blower motor running smoothly. I replaced the air switch and motor running cap; no luck. Finally, I decided to dig out the blower and took a look. Then I found out all of the fan blades inside the blower were gone rusted and completely shattered. It was somewhat mind blowing for me to see this as I never opened a gas heater before.
Now, the next question is should I drop in a new blower (~$500) or replace the whole gas heater with a new one (~$2500). The heater is quite old and I would not like to see if something else starts break down after fixing the blower.
I’m attaching a photo of the burner underneath the blower as shown below. There is obvious rust on the burner. Would you think this seems OK for another two years or this degree of rust is not acceptable and requires a replacement as well?
Thanks!
