Hi Thanks for the information. You have this heater here Pentair MasterTemp 460736 Parts Diagram we would suggest replacing with this MasterTemp Control Board Key #15 and this Membrane Pad Replacement Key #18 You could try just replacing Key #15 and if that doesn’t do the trick then also replace key #18.
Replaced control board #15 didn’t solve the problem and it was expensive. Waiting on membrane pad to arrive. My gut tells me that something else may be the problem but not sure.
I don’t want to pour a ton of money into something that isn’t going to work. Any ideas?
Doesn’t seem to respond to any button pushes on the keypad. Used to hear it ignite when I pressed a button, but now I hear nothing.
The LCD screen lights up and when I press the yellow button on the back of the control panel seems like it goes through a process where pool on and spa on lights light up and the LCD is on, but nothing further ever happens.
