I still have the non-GFCI CB installed, and it hasn't tripped - so it's inconclusive at the moment if the ignitor was causing the GFCI trip or not - I'll have to swap back to see if it trips. Right now I'm at a better spot than I was last week - so thank you for that. (y)

Hey Allen - removed the bottom bolt. No water came out, but the end of the bolt does have corrosion on the tip - not sure if this is normal for a 5 year old heater or not. That being said, I slowly started replacing things. I removed the Stack Flu sensor because it was easy to get at. It...

It's a Craftsmans 82141 that I've had for years. I can't find anything that says "True RMS", so I'm assuming it is not a True RMS meter. It's like this one...

Thanks AJW - yes, I've read the article - multiple times in fact. What I cannot understand from the article is what actually detects the flame? I understand that the Fenwal box is the microprocessor, but since it's detecting 0 VDC across the FC+ and FC- pins., according to the article it leads...

So I got a brand new replacement Fenwal box - swapped it out, and I'm at the same spot. Heater fires for a second or two, and then turns off. Does this 3x, and then the Fenwal box reports "Ignition lockout". I have already done the grounding suggestion done in...

Yes, I just observed this. I think before I was waiting until it said "Service Heater", and then looking into the Fenwal box - at that point the diagnostic Fenwal LED has gone out. If you watch the ignition real time, after the 3rd time lighting, the diagnostic LED inside the Fenwal box...

So I swapped out the GFCI breaker for a non-GFCI. I think that there's a flame sensing issue, because the blower starts up, the heater lights, and then after about 1-2 seconds, ignition goes out, but the blower continues to run. This process of lighting / going out happens 3x, and then the...

So the thermal regulator seems to have helped with the cycling. What's odd is that the old thermal regulator that I pulled seemed to function as well when running it under hot tap water. There was a small foreign piece of plastic on the end of the thermal regulator (round, white, about the...

So the Thermal Regulator is on it's way - should be here tomorrow. In the mean time, I did have a chance to witness it trip the breaker this afternoon. Here's what happened: 1.) I turned up the heat on the IntelliCenter while standing by the heater - the heater had been off since Wednesday...

Thanks! Thermal regulator on it's way - I'll report back.

Took the VS to 2800, which is about 63 GPM according to the FloVis - the burner is still cycling every 30 seconds. When I initially start the heater, it runs longer (like maybe 90 seconds - 2 minutes), and then all subsequent cycles are 30 seconds on, 30 seconds off.

Thanks Allen - fine with separating the two. I'll replace the breaker and see what happens. As for the heating issue, the "Service Heater" light has not been on since yesterday morning just after I reset the tripped breaker. Right now it's cycling where the burner fires for 30 seconds (and...
