3-way refrigerator on 2019 T@B 320-S is very difficult to light to run off gas

jtalarek

Sometimes my fridge will light off gas but usually it is near impossible and I finally give up.  Even when the fridge is already cold and I have pre-lit the stove to be sure the gas is flowing, I click the igniter repeatedly with no luck.  The problem times seem to be getting more frequent.  Any advise?

We had the same issue in our 2017 320-S. Make a preacher talk bad trying to get it lit. Once it was lit, it was fine or as fine as absorption refrigerators get.

Just recently went through few hours of troubleshooting the same issue on my 2017 320s

The sparker could be too far from the burner to create a spark, or the flame sensor has moved and is not directly over the flame. In either case you have to open the bottom side panel to get at the burner compartment and then remove the small panel covering the burner. There you will see the sparker and the flame sensor. With someone help you can watch what happens when the sparker is pressed to see if there is a spark, you can also light it manually to make sure there is gas flow. One other thing to try before doing this deep dive is to drop the front of the trailer, this will cause the flame to tilt toward the back of the burner and  the flame sensor, if it lights then this will confirm that the flame sensor is not in the right position. Good luck. In my case I had to reposition the flame sensor.

@jtalarek, see the document I posted in the link below regarding that refrigerator (I am assuming you have the same one as I have in my 2019 320 S.)  Maybe it will help you out.  Good luck!

A wealth of information!  Thank you so much

So I slowed down and followed all the steps - including being more precise about leveling side to side - and I got the fridge to light!  Thank you all so much!

What year is your Tab? (You might want to put that info in your sig line for future postings)

The level of the Tab won't matter so much with whether or not it lights, but does matter when it comes to being able to cool. 

Good pointers above, but my problem turned out to be a loose flame-sensing thermocouple. In ours, that connection is under the stove-top, but it may be different on yours, if a different model or year. I eventually secured the thermocouple nut with loctite.
