You said no flame... Nothing

Could still be the board, or solenoid on gas valve?

First thing I do is link out the controls and take it from there.

How can't it be the PCB , is the pump not running either, is everything not wired off the small PCB
Is the pilot not manual as not electronic ignition.

I'm not saying it's the PCB, I was just querying last message. Take a test meter and trace where power is and isn't and eliminate as you go, like Graham said about linking out, you'll find that what ever needs linked out needs fix I ng lol

Pump is ok
