Gas side of fridge out

[campigloo]

Hi y'all. Hoping someone has an idea. My brain hurts.
I have a Dometic 2652 fridge. It no longer works in the gas mode. I've cleaned the burner, cleaned the contacts on the gas solenoid, replaced the igniter and replaced the control panel. I now have voltage every where I know it's supposed to be, but still nothing even trying to happen.
Anything short of take it to the shop would be appreciated. The shop is my next step.
Thanks!

I had a similar problem several years back. I actually went for quite a long time with no gas operation. I finally dug into the thing again and tested the fuses (2). Low and behold one of the fuses looked just fine however upon testing there was no continuity through the fuse. I replaced the 25 cent fuse and the fridge lit up immediately on LPG.

Moral of the story. Everything is not necessarily as it appears!

That is really strange.........:H


Fuses in 2-way Absorption Fridges (3A-5A)
*AC fuse for the AC electric heat element circuit
*DC fuse(s) for the DC circuit which includes propane system AND the fridge control circuit.
IF DC fuse not functioning (blown/bad contacts etc) then NO Fridge operation

No LP function is not due to a DC fuse issue. DC fuse issue means nothing works----no panel lights, no AC/LP---nothing

(3-way......30A DC fuse for DC Electric Heater Element)

No spark..

Then issue is back at circuit board or with spark electrode (positioning, gap, high tension wire contacts)

IF spark electrode is NOT getting DC Voltage then neither will the gas valve solenoid.

Thanks Charlie but it does have a good supply.

Is it getting Gas???

I assume the tanks are full and that the stove works but, could the supply line to the fridges gas have gotten kinked, blocked, somehow?

I know this is highly unlikely but, I thought I would mention it.

No. new igniter and still no spark

Thanks

the valve doesn't get soaked....just the orifice


Getting spark?

Does it swap to GAS..fridge in AUTO mode and you unplug AC ??

Does it go to GAS in manual mode?

Does the spark electrode produce a strong spark?

When it sparks do you feel gas valve solenoid click/buzz/vibrate OR have you checked for DC Voltage at solenoid while electrode is sparking?
(Gas valve only gets DC Voltage during sparking event for 6-8 seconds)


Does Main Flame light off at all?

Have you cleaned gas valve orifice.......unscrew/soak in alcohol then blow with air?
