Review on Supco Universal UET120 120V Electronic Refrigerator Defrost Timer Control by Janet Battle

Easy to set up and install Schedule a 30 minute defrost cycle every 12 hours. pressed the button to ensure that the defrost heater is on. Press again to return to compressor run mode and the compressor will run. everything worked fine for 3 days, the compressor turned on and off normally. Then after 3 days I noticed the fridge and freezer were heating up, turned the thermostat down and back to the 38 degree setting, the timer clicked either way past that point, but the compressor wasn't working so I installed that old mechanical again and it works fine now. Apparently the compressor/fan contacts in the electronic timer have failed?
