Power on OLED only when refrigerator door is open #33

Maybe just a NO plunger type switch when door is open in-line with OLED power or ground. Why? The OLED is starting to burn in pretty badly!

DO THIS: Use 120VAC relay connected to existing plunger switch/light circuit to act as a dry contact for OLED ground.
