This stupid thing is still icing up and we have replaced the heating element and the thermostat. I have resorted to defrosting it with a hairdryer every 2-3 weeks since I am tight on money (like most of us). It works great after that, and then starts humming and I know it’s time to do it again. Any ideas? It is only about 5 years old. I really appreciate it!
