I have Pentair Maxmini400 that is about 15 years old. It function ok but occasionally produces "explosion" type sound ( most likely build up of gas). It is natural gas heater. It continues to cycle and heat water but every 5-7th cycle it "explodes". The pool company I use told me that my control panel went bad because signal ( voltage) to the gas valve sometimes doesn't get there ( meaning voltage is lower than normal sent from control panel). Since unit of old they suggested to replace it since they don't know for sure ( I guess nothing is guaranteed in this world) that it will fix the problem and unit is old.
I found control panel for like $150 on Amazon for my pool... Should I try to repair or replace it?
If replace, would you suggest I pay for company to buy andinstall ( 3 year warranty by Pentair) vs I buy and they install ( 1 year warranty from Pentair then).
Thank you again.
