Hello, My Maytag upright freezer just stopped working completely. Clean power source. The interior light works but all temperature is lost. No compressor noise+ totally silent. Any ideas appreciated.

Where is the defrost timer located? We think the thermostat is working fine but cannot find the defrost timer. The parts diagrams are not showing where. Thanks, Bruce

Latest Questions

This is not triggering the defrost cycle frequently enough. Is there a way to wire up this part so that it runs continuously - not just when the compressor is on? I would like it to trigger once every 12 hours of elapsed time.

We just bought these dual Whirlpool Side-by-Sides to replace older units that were starting to have issues. Unfortunately the new units ice up after a couple of weeks. If I manually advance the 3-81329 defrost timer then everything is great. My theory is that Whirlpool is being to optimistic (waiting too long to defrost) to keep the energy efficiency high. And this is causing the ice buildup - especially with our very humid climate in Seattle. We also read that this timer only counts the time the compressor runs - not elapsed time. Not sure if this is true or not. In any case, we would like to replace this 12-hour timer with say an equivalent 8-hour timer or least a timer that is more aggressive about running the defrost cycle. Any recommendations?
