Thanks to all who read this - I was the weak link in the chain as one of the relays was indeed "fried" & not working. I bypassed the relay (used the un-used one next to it there appears to be a few extras & everything appears to be working fine.... Best to all - I love this forum & its experts that "donate" their time...

Thanks for the reply - Regarding the CGFI breaker - if was not tripping with the test button on the breaker itself. Once I replaced the breaker at the subpanel, it is now working fine (i.e., will trip when pressed). The spa was purchased in 1999 and I don't believe (I can't locate) any interlock switch or anything resembling a magnetic interlock. I did close up all the panels with all screws once I finished and the behavior is the same. There is no heat. THe blowers, circulation pump etc - all work perfectly. Any additional feedback would be appreciated

Hi - I have enuf knowledge probably to be a little dangerous but really could use some help. After a brief winter shutdown of my HS Landmark (purged all water), it started up & heated up just fine...then the heater quit (everything else is fine). Below are the specifics - any advise would be welcomed (kidding aside, I'm handy with a volt meter and understand the basics): My 5-6 year old IQ 2000 (NOT IQ 2020) heater red LED is on, as is the LIM OK light. The remote light off as it is unplugged. When I opened the box the White hot wire was charred but still carrying a load (I replaced the flag connectors on all the heater wires). Voltages coming in from the panel & at the output of the relay are "normal" (i.e. black to ground 120, white to ground 120, black to white 220+). The contacts look a bit blackened but are energized. I get 9.3 ohms when testing my 7-8 year old no fault 6000 heater (using black & white wires). I replaced the 30 amp GFI breaker @ the sub panel as it was not tripping - but still no luck. Again - any help would be greatly appreciated! If I need new heater or control box then so be it - just want to make sure I have this diagnosed correctly before spending more $$$.
