I've had a True TDD2 beer fridge for 8 years (2 doors, 2 taps). The dial settings inside run from 0 to 9. I've always had it set at 5. It started freezing stuff inside recently. It runs a lot. Coil fins are not clogged. I've always kept a thermometer inside and it would read from 34-46 degrees. It was recently reading 22 degrees. I dropped the dial down to a 2+ and it's still reading about 26 degrees 24 hours later. Do I call a repairman or is there something I could do on my own?
