Frosty keg kegerator won't go above 10 degrees F.

[Leoniabrewing]

I have had the great northern frosty keg kegerator for several years. After moving the temp sensor initially to get colder beer it has been dead on balls accurate for many moons. All of a sudden "bam" frozen keg. It had a WPF 14B L-1 (made in china) thermostat. I couldn't find one anywhere so I replaced it with a WPF 20 with similar specs. I can't get this to go above 10 degrees. The coarse screw adjustments made no difference. I'm at a loss. BTW where are the coils? Are they concealed and if so how do I get to them to clean them. I hate to toss it because it was a gift and we've been through a lot (of kegs) together. All info is appreciated. Cheers!
