In The Industry
Been there, done that a few times with these raypaks. I will say this isn't something that can be addressed online. Everything from are the labels in the inside beening burnt, to what poolman said, to the board etc. I always try to hot start the heater, sometimes from the rollout just to rule out the board. because frankly Raypak should come with a free pack of replacement boards. Because they go out so easy. Go with what your new guy says. Because this is an impossable guess from online with a Raypak.
