Question about Pentair MiniMax 100 Aboveground 100,000 BTU Propane Gas Electronic Heater
Hi, I need to pull out the heat exchanger to see if it is cracked, can you give me the steps? Also, can such a crack be fixed by a welder? Thanks.

Yes I just had the same problem, the guy that I bought the house from told me to drain the pump and the filter,etc. But failed to mention there is three brass plugs on the side of the unit, so the heat exchanger cracked, but i took it to a general welding shop and they welded the crack up so that saved me a bunch of money That is all you have to do

start with pressure switch,likely out of adjustment or it could be faulty.if you're going attempt to adjust,press sw,you should be familar with using a multi-meter.improperly adj could result in ruining htr and possibly a fire hazard

Sounds like the controller is the problem. This is the circuit board that has the display and controls on it. You can swing that panel open and try tapping on the white plastic cover the controller is under that. This might get the fan relay to release but you will have to replace the controller it will stick again

This is a fan falure code. It can mean the fan has problems (not likley if the fan goes and isn't labored) You have a sensor in your exaust (probally not this if you don't get a good start) The culperet is probally in the negetive pressure sensor. This is a 2-3 inch disc with wires going to the controls and a rubber tube going to the fan. Pull the tube from the fan and make sure the fan fitting is clear (poke with a tooth pic) Be sure their are no kinks in the hose. If the heater is 4 years old the diaprahm could be bad in the pressure sensor. Check the other things first but this is probally your problem. Good luck, hope this helped.
