hi everyone, I am new to this forum and a pool novice. (please don't beat me up) I have a Pentair minimax CH 150. It is only a year old. The heater will fire up, run for a few minutes, then shut down, then refire. on and on. After talking with pool tech and trying different things( clean filter, run with no filter, to see if flow problem) didn't work. tried jumping pressure switch, this seemed to keep heater lit for a while, didnt shut down. I thought it was burning a little yellow so i shut off. So,,, pressure switch bad??part #472125 They want an $85 service call plus $85 an hour to fix plus parts. is this something i can do myself? or leave to the pros? If so, can anyone give advice and details on what to do? I see where adjusting the pressure switch should be left to the pros but can i simply change/swap out a new one? any help? thank you!!!!!!!!!!!!!

I have a 30k gal in ground pool with a heater. I never noticed this before, but I replaced the pump motor this year and I was keeping a closer eye on things. When I route the water thru the heater the pressure goes up a few lbs. Is this normal or do I have a partial blockage in the heater?
