After reading so many threads on refrigerator
problems and off the wall answers, I'm trying to be polite here, I thought I would post the two most important steps.
If your refrigerator
basically works but does not cool enough or the flame goes out then read on.
The fact you can see a small flame only means the unit is basically working.
(1) Has the yearly maintenance been done? That includes cleaning the jet and burner.
(2) The fact that all other appliances seem to be working correctly is not a good indication.
Here's why. Your water heater, stove and furnace
all have secondary regulators built into them that further lowers the propane
pressure, so they won't exhibit any problems.
But your Dometic refrigerator does not have a secondary regulator built in and depends entirely on the main propane regulator to supply proper pressure.
So step two is to check or have checked the pressure of the propane
system. Regulators in my experience seem to lower the pressure as they age. If your trailer is older it may be time for a new regulator and hoses. Casita
on line parts has the regulator, two short hoses to the tank and the 36" hose for $60 a very reasonable price. They most likely will work for most other trailers too. Here's the link.
If this post helps only one person it's been worth the time my time.
