I am knee deep into troubleshooting this no heat issue and I'm now stuck and need some advise.
The RP2100 isn't heating anymore and I've done some debugging and here is where I'm at:
I smell no gas (first tell tell sign why I don't have hot water)
I hear no thud or commotion from the gas valve at all
I hear no zapping sound from the igniter
I have a green power light
I have no alarms
I've turned the gas on and off at the inlet
I've powered down and turned the gas off on the gas valve (everything turns easy)
I've checked the burners, not rusted, I've checked the pilot igniter and cleaned around it.
I've powered it down and removed all the connectors and reseated them
I've removed the PC Board and reseated all those connectors as well.
When I reset the system a red light comes on for a second then I get the green power light, red light clears, everything indicator is good... the spa is on, the heat light is on, the panel in the house lets me change the temp, just still no spark, no flame and no heat.
What-else can you guys suggest, thinking at this point I am pretty much at swapping boards but I'm open to any ideas before I spent money
-thanks in advance.
