I bought a house that came with a somewhat dated SPA that was inoperable at the time. The seller pretty much got everything working except the pool heater. Per the previous owner, I ordered a new updated Integrated Pilot Module Ignition Control Circuit from Amazon, specifically this one:
I hooked this one up and it would fire up the heater, uncontrollably. Specifically, when I hooked up the new board the heater would ignite itself and turn on full blast and there was no way to turn it off without disconnecting it, very dangerous. My friend in HVAC and a SPA guy we hired couldn't figure out how to set it up correctly. The SPA guy we hired recommended replacing with the same model circuit control board that was originally on the unit: s86a.
I received a unit from ebay, which looked good, and hooked it up this morning, but I'm having trouble trying to figure out how to ignite the pilot and start it. I tried turning the knob to ON and pushing it down, but did not hear any clicking indicating the pilot was being ignited, like it did when I hooked up the amazon one (the one that would self-ignite automatically).
I'm kind of stumped, so was looking for help. Here are some pictures of the heater:
Was hoping your knowledgeable folks could help out.
