| Gas fridges should not be used while running on the road. The consequences of refuelling at a servo near where some other vehicle is beingness refuelled with gas there is e'er the problem of a small gas cloud when an inefficient refueller removes the connexion from his vehicle.The gas is heavier than air and will waft forth at depression level and you have a pilot lite on. Information technology will happen one day. Years ago when fridges were only ii way I used to travel with the gas on. These days too risky. Promise you get your fridge sorted out with the gas problem. Use prissy heavy wire direct from the battery ,a fuse and an Anderson plug and your fridge will be colder than running it on gas and you and others volition be much safer. Thanks. -- Edited by patrol03 on Tuesday 26th of September 2022 06:25:59 PM | |
| We have a Dometic 3 way fridge in our caravan bought new 5 years ago. It's a different model to yours but they're pretty much withal except for sizes. Ours has stopped working on gas twice & 240V one time over the 5 years. We got ours stock-still by a gas fitter in Yeppoon when we were upwardly north a few months ago, cost us $70 cash in hand. He cleared a blocked jet & re-aligned the flame which was out of alignment. Works very well now. He said that even just changing gas bottles can cause a blockage if a small particle gets loose in the system. On the 2 other occasions that it bankrupt down we had it repaired & serviced past a caravan refrigeration specialist in Melbourne. Nosotros could of bought a new fridge with the money they charged. Good luck with yours. Thank you Keith & Judy Don't accept life as well seriously, it never ends well. Trip Reports posted on feathersandphotos.com.au Get to Forums and so Trip Reports. � | |

Tony Bev wrote: That makes sense to us. Ours struggles when the temperature hits 30 degrees when its on gas. Fourth dimension to head for a caravan park, it�copes OK on 240V. Forgot to say that nosotros had an extraction fan fitted & sail runway fitted for 90% shade cloth over the side that the fridge is on. Ours is the Dometic 90L. The freezer section copes no matter what temperature it is but in the past the fridge section has failed us quite a few times & nosotros've had to ditch nutrient. The new measures have helped a flake.�� Cheers Keith & Judy Don't take life besides seriously, it never ends well.

| Re (My theory is that the thermostat has failed ) I do not know if the Thermo. controls the temp on 240Vac. We had problem with a dissimilar frig to yours when on Gas. Probably a grand child had played with the Thermo knob and you could turn it, just zippo would happen the shaft had been broken. Could be your trouble. Peter | |

| A bit of an update I had the gas side of the fridge serviced yesterday I volition presume that, "Cleaned out Gas lines", means, that there may have been something in the gas lines Since I last tried to use the fridge on gas, I have purchased a wireless thermometer, with three stations At the 17 hour mark, I noticed that the freezer, and fridge had started to warm up Just after the 24 hour reading, I went to meet what I could meet, which was zip I tried to meet if there was any 12 volt power to the "GAS VALVE", none on the correct side, but perhaps the rust of the positive connection was stopping the multi-meter probe from making a reading Still guessing that the "GAS VALVE" or what I would call the gas thermostat is the problem Afterward in a few days, I shall do the same test on 240 volt Hoping that one of the techies can give me a clue, and will appreciate whatever guidelines Tony It cost nothing to be polite | |

| I now surrender and throw the towel in, in regards to this refrigerator
The fridge works as it should until the ambience temperature gets above about xxx�C and from that point on, it is just non reliable I removed the fridge, very difficult every bit either the wood has swelled, or the fridge sides had buckled, since it was installed I have ordered a 12 volt upright fridge, with a climate class of T+, supposed to be good for 43�C I am not knocking this three fashion fridge, considering my brother has the same type, made in 2022, which appears to work OK, while mine was probably made in 2006 All I can say in layman speak, is that I could not observe any visible fault with any of the parts mentioned above Tony It cost nothing to be polite | |
| Here is the RM7401 set up. RM7401L stopped on gas just. Establish that if unit works ok on 230Vac/12Vdc then most controls and electrics are serviceable. My problem was rust in gas pipes that it blew rust thru the organization and blocked the jet in the gas burner jet. (When viewed/checked u can't see thru equally it a homo fabricated spiral formed ruby jet). If one uses autogas and then clean out gas lines every 6 months & LPG annually. Clean jets + gas burner with Alcohol (methylated spirits). Tried all to a higher place merely rust had got into ruby jet so last resort i put 1 small drop of Phosphoric Acid and instantly cleared the jet on burner and started to cool unit but not skillful enough for me on 38degC solar day at -3/+xix Freezer/Fridge. Next I installed 2 fans from Jaycar YX2570 on top of fins at peak of unit of measurement on correct side and 50degC thermostat and walla now at 36degC -x/+11 deg. Of import that thermostat on left side every bit coolest place from 40 - 60deg. Fan is 12Vdc at 80ma each 20cfm, 80x80x25mm and volition brand up an angled bracket to mount 2 fans and thermostat. Then happy at present and best 73s | |
| Sorry for the late reply, VK5TBC Whatsoever my problem was, it was not rust in the pipes, as I had removed the jet, and blew out the pipes with compressed air, prior to giving upwards and having a gas fridge service washed I had built a deflector plate between the top of fridge and top outlet/inspection grill, and was using three 80 mm ball begetting computer type fans I take removed my gas fridge, then I now no longer accept bug, to write home almost Thank you for your imput Tony It toll cipher to be polite | |
| As my final post on this particular thread I had fitted an EVERCOOL Platinum 110 Litre 12/24 Volt Fridge Information technology has lived up to its advertised promise of being a climate "T plus" rating of good for upwards to 46 C In January 2022 at Kimba SA, it was 43 C out side, and over 46 C inside the motorhome, and with the fridge ready at two C, the beer was cold The dominate is rapt with the refrigerator, as we never threw any food abroad In the spirit of EXplaining, and non Lament, hither is what I thought could be the downside of this refrigerator

Usual disclaimer
I am not a Gas Fitter, I do not play around with LPG, and I have non posted to offset a flame state of war
Can someone shed a bit of light on a Dometic RM 7401 three way fridge problem
History is around March (seven months ago), prior to crossing the Nullarbor from east to due west, I must have purchased a bad bottle of gas somewhere
The fridge stopped working on gas, and I noticed the flame on the gas stove became very low
Removing the gas regulator, when I returned home, I noticed a mustard coloured fluid inside one of the pigtails
Setting up a manometer using compressed air, the regulator was only giving less than 5 inches of water force per unit area
A new regulator and pigtails cured this trouble
Returning home this month from a second trip, September (so not hot weather), once once again the fridge failed on gas, while coming across the Nullarbor from east to west
It works on 240 VAC
It will hold its own on 12 VDC
Both the stove and gas hot water heater are working OK
The regulator does still have xi inches of h2o pressure
Using an inspection camera shows a blue flame, and a make clean boiler chimney
It is booked in for a service simply there was a ii week wait
My theory is that the thermostat has failed or is blocked enough to slow the flow of gas to the boiler
The picture below shows what I think is the gas thermostat, as it has the gas lines going in from the bottles, and out to the flame
I notice what looks like 2 insulated (I assume live) and 1 bare end (I assume is an earth) wires
Can someone shed a calorie-free, how the thermostat works, and how should I bank check the wires with my multimeter, and so that I can eliminate the switch/circuit board, which I volition not exist able to admission without removing the fridge, as they are situated on top of the refrigerator
Whatever assist/guidance will be appreciated
