This has to be the easiest one yet.
I striped a perfectly good fridge to make this! I removed the inside door liner to make more room. In the bottom you see a Hovabator style thermostat, low RPM PC fan and a heat pad. This is where the problem lies, the pad is not getting hot enough. I have to find something else.
This is adjuster and an idicator light. When the light is on the heat is on. When it's off the heat's off.

Thanks for looking,
