Since you are in SW Michigan, you are not far from Shipshewana, Indiana. Give Glenn Miller a call at National Refrigeration at 260-768-7059. You will not be disappointed. He will troubleshoot your fridge and fix it and he doesn't charge an arm and a leg. He's an Amish man, very honest, etc. He bought the business from Leon Hershberger and has relocated on SR120 north of Shipshewana about 1 1/4 miles. It's on a curve, new building. . . you can't miss it.
Address is 6755 W SR 120, Shipshewana.
He's troubleshooted mine a few weeks ago. Spent 45 minutes on it and didn't charge me. He couldn't fix it, but it wasn't the fridge. . . it was an electrical problem at the outlet. A friend in the campground (an electrical engineer) fixed it. That same friend had to run over to Shipshewana the next week and have Glenn change out the cooling unit in his fridge for $1100. Running great now, but his boiler had ruptured.
He will fix you up for sure.
