I own a 1996 Holiday Rambler Vacationer SE, Class A motorhome. This is my first RV and I've been fixing any issues (LOTS OF ISSUES! -.-) by myself to save money. I was having an issue with my water heater (before I fixed anything) where I would switch the switch on and it would be in lockout mode and I'd have to switch it on and off for like 40 minutes before it'd kick on. Sometimes it'd stay on, sometimes it wouldn't. Sometimes it would reheat properly, sometimes it wouldn't. Sometimes I just couldn't get it out of lockout and I'd have to try the next day.
Fast forward. I want to fix this thing. I bought all new parts on Amazon. This included, new control board, new eco and thermo, and new thermal cutoff. I replaced everything and finally got to the wiring where I was confused. The connector was different then the one I had on before but I was assured this control panel would work with my model, the G6A-8E. After TONS of trial and error switching the cables in different spots (probably not the best idea, I know) I finally found a wire sequence where the igniter would start sparking and the lockout light would stay off. (I looked in the manual for the wiring sequence. The one it showed didn't work. I looked everywhere online, couldn't find anything and the sequence of wiring before I switched out the board didn't work either). After buttoning everything up and a very long day I went inside and held my breath as I pressed the switch.
BOOM! IGNITION! FLAWLESSLY!
I can't tell you how happy I was, let alone my wife. I took a super hot amazing shower. As soon as the hot water in the tank dropped I heard it kick back on, beautifully. My wife took a shower; kicked right back on. Dishes were next; kicked right on. I thought this was the end of the hot water fiasco. Another challenge triumphed. Wellllllllllllllll, I was wrong.
The next night my wife went to switch on the water heater so we could do dishes. Then came the dreaded, "Juuuuuuusssssstinnn........... The water heater isn't turning on". I always assume she messes something up so I go and check but low and behold; not working. I go outside do my normal checks, wires, connections, etc. I have her try it a couple of times and I realize the igniter is still sparking but I don't hear propane spraying at all. The other strange thing is the lockout light didn't come on (which makes me wonder if my wiring sequence is still wrong). I've tried all sorts of things, checked everything I could on the internet, check my manual, but I can not figure this out. I'm hoping it is the stupid wiring sequence but I am just confused why it worked flawless just for the next day it not to work at all. I have propane and the stove tops have been working fine. This is my last resort before calling a tech, which I don't want to do.
