Anyone out there have an intermittent problem with their refrigerator? Mine will work and then not do so good. It never stops working but the refrig section will get up to 50 degrees at times and maybe down to 42 degrees over night. It will do this for a few days and then work more normally i.e. 40 degrees and creap up to as much as 44 degrees during the hot day. Outside temp runs from 75 degrees in the morning to 100 by afternoon. I made an appointment to take it in for service and over a weeks time it ran better than ever (38 degrees to 40 degrees)! I get out on a trip as I am now, and for 4 days it got up to as much as 50 degrees in the frig section and only to 44 degrees over night. Now, all the sudden - and I have done nothing different, this morning it is 38 degrees in the frig section. What's going on? The freezer stays at 18 to 20 degrees all the time. We have been in the same location for 5 days now, hooked up to electric. The frig works even worse on gas.
