First plumbing now electrical. For those readers keeping score, this is the same new Suburban water heater that I had plumbing issues with (Post "Water heater won't fill") but resolved thanks to help from GS Forum experts.
But now the WH won't light. Here are the details:
I installed a new Suburban WH (gas only), hit the WH switch and heard the burner light. The tank was empty so I turned it off immediately. After going through the plumbing issues detailed earlier, I got the tank filled, hit the reset button on the face of the WH, toggled the WH switch and the "pilot out" light went on. I cycled the switch a few times (per the manual) and this light went off, but no ignition.
I got down and checked the three wires you have to connect to the WH for installation (red, blue and yellow). I used crimp connectors - which I'm not crazy about, although the coach is full of them - but thought maybe one was loose. So I gave each a couple tugs. I also read about cheap controller boards failing (burned component) so I opened the controller board enclosure, checked the board, the multi-wire connector and the high voltage wire to the ignitor. Everything was good so I screwed it back to the wall.
I guess I'd left the WH switch ON because about 10 seconds later the burner lit. Woohoo!
Assuming the crimp connectors were indeed the problem, I turned off the WH switch and decided to go outside and solder those connections (can't reach wires from the inside). Before I did this I wanted to hear the burner light again, so I turned the WH switch back on - no joy.
I went ahead and soldered the connections anyway and tried the WH switch (after hitting the reset button again) - nothing. But I didn't get the "pilot out" light either.
I've also checked the DC fuses several times - nothing blown.
At this point I'm out of ideas. Does anyone have a suggestion?
What am I missing?
Thanks a lot.
