The old lady is choosing to believe a “guardian angel” repaired her furnace. Last Winter, hours (and dollars) spent in an effort to get furnace to work.  I had to rely on the “heat strip” for heat and it was less satisfactory and more expensive (electricity). Recently, almost one-thousand dollars for new, large propane tank, and one-hundred-twenty gallons of propane. Before severely cold weather, I wanted to “test” the furnace–in case I need to contact repairmen. It appears to be working fine, Praise the Lord!! ~~ Furthermore, the RV refrigerator is “working”–but not extremely cold. An angel repair?? Perhaps the extreme heat took a toll on the refrigerator like it took a toll on the old lady??
