Fridge on propane

[noleakman]

I have a Norcold 1200 When you are on propane and the fridge gets cold enough will the burner you can hear go out and when it needs to be colder it comes back on!Some times I can hear mine some time not! The fridge runs about 33 degrees!

YEP.......

Thermister is the sensing bulb for thermostat. It senses fin temp which is 10*F colder than food section.

Thermostat turns propane & electric element ON/OFF as needed to maintain temp set point.

Bad thermister OR one that has fallen down will cause continuous operation.......frozen stuff in food section of fridge

Sounds perfectly normal to me.

I have had three or four 1200 Norcold refrigerators over the years in various motorhomes. I could hear the flame when it was on in all of them. It may be a small flame, but you can hear it plainly inside the motorhome at the refrigerator if you concentrate and listen for it.

I hear it outside coming from the vent!

Well if you hear it ...

That is a very small burner,, IT should not be loud enough to hear.

The burner will turn off when the fridge is at temp then come on again on temp rise. If it was on all the time it will get too cold.

It seemed like the burner ran all the time in the past!

So what's the problem?
