Don S Hummelstown , PA August 21, 2023 The freezer and refrigerator not cool enough. Observed freezer coils were totally iced up. Observed the defrost heater was broken. Looked kind of like a burned out lightbulb. Replaced the defrost heater. Also replaced the temp sensor just in case. Freezer and fridge have been working great since. Temp is under control again. Was able to decrease it from the coldest setting now that it's working properly. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
