1."working" is non descript. What needs to be known is, when you thought it was working what was the actual temp inside and in the freezer.
2. The USUAL cause of your type complaint and assuming the refer WAS getting below 36 degrees in the bottom, OFF LEVEL operation. Your complaint is classic OFF LEVEL operation. Works when level and when off level to spec fails to cool.
3. Burping is done by people that have no clue as to how refers operate and what an actual blockage is. Burping in some cases will restore some cooling(but NOT full cooling) but will fail again within a few weeks if the unit is indeed blocked. Doug

Forgot, your model may have rear 12 volt cooling fans(most 1292's did) and if so also would be a cause of intermittent cooling if the fans did not operate as designed. Also, is this refer in a slide room?

Actual temp inside the freezer was 31.

We are level.

Refer is not in a slide.

As I stated in item 1. YOUR REFER IS NOT OPERATING ANYWHERE CLOSE TO SPEC. Freezer should ALWAYS be below 10 degrees. 31 degrees is not even close. Doug

A few people say to turn the fridge upside-down to 'burp' the cooling unit.
This assumes the refrigerant has not leaked out.

Propane Lights off..stays lit------BUT NO cooling effect

Electric doesn't get hot
(Check that the 120V AC Outlet cord plugs into actually works.......then check the 5A Fuse on control board---it is the glass fuse. Have to unplug AC Power cord AND DC leads to remove cover)
IF the 5A Fuse is blown then element could be bad----BOTH have to work for electric to function)

Cooling unit could be BAD

Unplug electric heater element LEADS from control board
Plug them directly into the 120V AC Outlet.......run fridge this way for minimum of 12 hours. This method will force cool fridge IF cooling unit is functional.

If fridge does NOT cool down......cooling unit blocked/obstructed---replace

Think you will find cooling unit BAD

Assuming the flame is good I think there is something wrong with the absorption process which is not really serviceable.

As for checking the flame is good... I can't help except to say it is time to take it to a pro you can trust.

Possibly the service manual would have more info.

Does the burner light the propane? When fridge stops working is the propane lit?
