If it hasn't been used recently the gas can dissipate from the lines. Our stove is above the fridge so I light a burner on the stove to make sure the gas is flowing, turn it of and then the fridge lights easier.

Ours was very difficult to get going the few times it was used on gas ,then gave in completely.Had to take the van to a Dometic service place. You will find them if you google. Took a while for him to find the problem, got new part & so far ok.Service man said there had been quite a few with the same problem.

G'day Nick,
My mate recently could not get his 3 way fridge to light so called me over after much swearing! I read the instruction book & it said that the thermostat setting for when you are using 240V had to be set to Zero if you switch to gas.
Did this & bingo away it went. He was really annoyed because by the time he called me over he had the fridge pulled out & the access panel on the van removed so he had to put it all back together again while I went back to camp & enjoyed a beer while having a laugh at his expense!

Not sure of the fringe brand but yours might be the same. Also make sure you purge any air out the line as well.
Cheers
Stu

Those absorbsion type fridges take about 12 hrs at least to start cooling. I have a portable 3 way fridge & it takes forever to get cool in comparison with my Engel compressor fridge.
Maybe wait till morning & it should be ok. They are pretty good once they get going, just take a while.

Sounds like you had air in the gas line. I let the gas run for about 20 seconds before pushing the piezo ignition & my pipe has a much shorter run than a van gas pipe. If you push the igniter straight away as you have found you try forever getting it to light.

had same problem with my fridge. Found the igniter switch was faulty would work if I hit it and not if I just turned it on normally. Replacement switch from Jaycar Electronics $3.50 and now works every time.

After you have tried all of the other suggestions and after many "tries" if it still does not light ensure the end of the bypass valve which sits in the gas flame has not come loose.sometimes it has a small bracket attached to it with one screw.If this screw comes loose the bulb can vibrate out of position... therefore the mercury in the bulb will not shift and as soon as you let go of the bypass knob the flame will go out. Readjust the position of the bulb so that it sits in the middle of the flame.Then try lighting again.
After all this if the fridge still does not work you will need to take the burner from below the boiler.You will see a small nut on the gas supply tube...carefully undo it and take out the jet.Soak the jet in metho for about 12 hours.After this period blow the jet out with air (DO NOT USE A PRICKER) and try lighting again.
If it still does not light it could be a gas thermostat malfunction.Take fridge to an authorised repairer.
Good Luck
