There was not much information on the internet about my model of Freezer.
So I left a post on APP's Repair Forum.
I got an answer from a Technician who suggested replacing the Control Board and the Thermistor.
I replaced the Control board only and the freezer is working fine.
I ordered the parts from APP and am 100% satisfied with my ordering experience.
The part was delivered ahead of promised time and was a perfect fit.
