Fridge lights and goes of after 5seconds

[jerryz]

My Dometic Fridge has had a Full service in October,,

New ignigter unit
New gas valve
New Burner and new Thermocouple ,,,
Full flue clean etc



was working fine then and 2 weeks week when I tested the van

Now its switching on for 5-10seconds then going out , last night it did stay on for 4hours after 19 attempts to start it but today its not starting again
gas comes for 5-10s ignites and then goes out .... I am now at a loss of what do do next , No EHC

i have tried every trick clean the ignigter and jet again ...???????

You’ve also posted that your Truma has stopped working. Do you have an electrical problem? Is your leisure battery charged? Has a fuse blown somewhere? Very strange that heating and fridge have stopped.

New Burner and new Thermocouple ,,,

I'll change my original diagnosis then

I have to say that I'm with StillGoing in that I don't believe in coincidences so for the Truma to have failed at the same time does make me want to start the investigation by looking at anything they have in common.

Lesiure battery is showing 12.93v , Solar is also charging ,, all Fuses checked ok visually and using multimeter ,, all cables are secure and so are connectors ,,, Truma has no lights on at all ,, first problem was fan stopped distributing warm air .

Fridge still lights up gas by goes off after a few seconds ,, circuits are not linked either ???

Everything else is working ...

Im probably going to have to cut this trip short and go home ,, this is 3rd time this year i have had problems with this kit ,
Im seriously thinking of giving up on this MH game as I am losing faith in all this equipment ,, I have not stinted in repairs and new parts to ensure reliability .And thats before I factor in cost and wasted time . My trust in MH service people is also now not very good ,, im having to solve issues they are supposed to have fixed ,,

If the solar is charging you are probably not getting an accurate reading on the leisure battery.

Switched off solar battery isolated shows12.7v. But the fridge has also now lost 12v feed ???Oh Please!. All fuses are ok lights and cooker oven all ok

I can feel your frustration. All I can suggest is isolating the solar, switch off EHU and follow the wiring from the leisure battery to the fridge with your multimeter to find out where the voltage drops. Then repeat with the Truma.

With both your fridge and your truma having problems. The common theme is gas supply. Have you checked your regulator?

Try lighting 2--4 hobs and seeing if they all stay lit or slowly or not so slowly die?
