Make and model of refer?
Most have to have 12 volts DC to operate.
What mode do you try to run it on, Gas, 120 or?
Won't run on 120 volts unless setup with inverter or some method of providing 120 volts AC.

If when traveling if you don't have 12v to the fridge you won't have spark to ignite propane (you do have propane turned on don't you). It may take a while to clear air from line. You should hear it spark every 1-2 seconds till lit or it gives up. If no spark check 12v panel to make sure fuse is good.

Do you have a 12 volt battery and if you do, does it hold a charge.
Without a charged battery you will not have brakes if you lose connection with your tow vehicle.
Your battery also is the igniter for your fridge without a charged battery you cannot use your fridge on gas.

Ok the RV type fridges. though in theory And I've seen absorption cooling units that were pure GAS no electricity at all other than the safeties and those... well they do not apply)

RV types use 12 volt to control operation and to ignite the propane. So if you do not have 12 volt (Battery power) in the trailer no joy.

Now how it works on gas.. When the Thermostat calls for COOL the control board opens the gas valve (A 12 volt device) and starts making 12DC into about a kilovolt AC (1000V) to generate sparks to ignite the gas.. After a period it looks to see if a thermocouple is generating a small voltage/current (IS HOT) and if so it keeps the gas flowing till the T-Stat says "I'm cold enough" .

Possible issues
No 12 volt
Propane off / out of (The instructions say turn it off when driving)
IF it works on propane when plugged with one exception the following do not apply

Spark gap too big (Very slight possibility it's "Just a tad" too big and the difference between battery and converter voltage is thus important. Very very low probability of this.

Spark gap way too big (Won't work on gas PERIOD)
Clogged gas jet
Bad gas valve
Bad thermocouple
Bad Control board

And the ever popular "Other issue".

One moving only.. IN some cases the design of the outer compartment causes the flame to blow out when moving. I've heard of it only never seen it in 12 years full time


Home was where I park it. but alas the.

I do not know what type fridge it is but it does have a freezer also in it that works good when still ( not moving )

While travelling, the 120V is not in play unless you run your generator while driving, so let's focus on the propane operation.

The fridge does not care if it's moving or not, so if it works on gas while parked, it should work while driving.

As mentioned above, the gas valve does need 12V to stay open. You said you cannot connect the 12V from the truck (why?) but as long as your battery is charged, that should be fine - do other 12V items work? Lights, etc?

There may be a fuse for the fridge 12v - either in the fuse panel or on the fridge board - but again, this should be ok if it works while parked & not plugged in.

The only other difference I can think of while driving is the wind - maybe the pilot/flame is getting blown out? Are you missing any covers/shields around the burner area or fridge access panel?

Maybe taping a piece of cardboard inside the access panel to block most (not all!) of the vents will reduce turbulence inside the access area?

That's all I can think of at the moment. Good luck!

yes I do have 12v battery inside the camper and IT will stay or have a good charge on the battery .. so I guess the only thing I can see that must be the wind ,, I only see a spark to light the gas // IF there is a pilot light I can not find one ..

Thanks to all for the help
