Modern refrigerators (post-2010) often replace the start relay, overload, and defrost timer with a and an inverter driver . The schematic changes significantly: Start at the Line After a preset compressor runtime (e
If the compressor does not run but the interior light works: Power travels from "C" to "N
The hot wire hits the thermostat. If the cabinet is warm, the thermostat contacts close. Power travels from "C" to "N.O." (Normally Open) terminal.
The primary goal of a refrigerator's electrical system is to manage the refrigeration cycle. By regulating power to specific components at specific times, the circuit ensures your food stays cold while preventing ice buildup on the internal coils. Core Components of a Refrigerator Circuit
If your refrigerator stops working, checking the circuit diagram allows you to:
