I have found the following description on my refrigator. Magic chef No frost Fifteen. MC-15CC No Frost 15cuft Refrig/Freezer Part Number: 162905 I see no other writing on it. It has an Ice Maker. What is happening the fan in the freezer carpment which is at the top is freezing up and the fan stops. I thaw it out with a hair dryer and it goes back to working but then it freezies up again. What should I do to fix it.
