April 2013 Good Sam Highways magazine
This issue has an article titled " Cleaning & Servicing an RV Absorption Refrigerator " starting on page 24.
It's a good helpful article that is well written as I think most articles in this magazine are. Having said that, this article fails to discuss that, to some of us anyway, mysterious Thermosistor or refrigerator temperature control.
This issue also has some electrical discussions articles also.
