Product review (4 stars): replaced control panel got better but always in e9 mode
Display went crazy, got e9 and e8 for shorted and open thermistor, temperature display all over the place, wouldn't run, replaced control panel got better but always in e9 mode, replaced thermistor, by soldering in, still e9. Resistance checked at thermistor, at plug underneath, and finally at pins on control panel. So I took this new  control  el circuit board out of housing and put in freezer door, runs perfect displays temp exactly as measured by thermometer in fridge. Plug connection underneath and between door and panel cleaned and coated in dielectric grease. If I put board in housing and Install in door I get wild temp reading and thermistor errors. I guess I'll have to make a protective cover and run without pretty plastic control housing. It's ugly but it works, carefully of exposed voltage on circuit board. I think longer pins would solve resistance issue between door connector and control panel
