Water heater igniter not working

[JKChic]

I have a 2002 Tioga which I bought in April. Everything was working fine when I got it. Took it on a trip to the sequoias in May/June this year. All was well. Now my hot water heater will not "tick" in order to get the water heater lit. Is this the igniter perhaps?

If so, is it an easy fix? What part do I get?

Thank you!!

Which BRAND/Model would be very helpful

From pictures looks like an Atwood..probably 6 gallon

Being a 2002 model the propane has its' own set of t-stats (outside compartment)

DC Voltage comes from module to 'T-stat' via Brown wire thru a 'thermal fuse' (clear tube device)
If it has blown NO DC goes anywhere
(You can remove it and hook brown wire directly to t-stat and see if propane works. IF it does.....get new thermal fuse. They are a one-shot fuse...and clean combustion/exhaust chamber cause you have had a blowback---flame out of chamber)

If thermal fuse is good......then DC goes to T-stat then from T-stat to module
From module to ECO (energy cut off---hi temp t-stat) on RED wire
From ECO on red to gas valve solenoids

No spark electrode firing.click, click, click
Sounds like thermal fuse is bad OR contacts on T-stat loose/dirty.
DC has to get from module to/thru t-stat before spark electrode can get DC Voltage

Not sure if this helps but its an Atwood G6A-8E model.

Wiring diagram for your model





Follow suggestions in my other post.

Find where the DC stops.....then correct issue
Main DC fuse from DC Dist Panel
On/OFF switch
Thermal fuse
T-stat
ECO
Gas valve
Etc

Follow the DC

Thank you Old-Biscuit. I really appreciate your help! I will try my best to figure this out!

I have the same model and I just had to fix mine. Same symptoms , it was the electronic board module. Why they go bad is unknown to me, one minute its great and next day it won't work. Check that the ground wire under the cover is good. Barring that, the part number has changed 4 times. I ended up buying the Atwood generic module board with electrode part #91363. Not cheap on amazon it was just over 100.00 or so.
Good luck.
