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?
