Thanks for the heads up! I don't know what LP is but I went back over there with the downloaded owners manual for the model of the fridge. They learned how to do the fridge burner lighting as I did. We had a thermostat in the fridge. It started at 70 and about 30 minutes later it had dropped to 50 degrees. The back panel behind the fridge on the outside looked like it hadn't been open in years. They said they would leave it on the gas overnight and I'm supposed to check it.
