How to Fix Whirlpool Refrigerator Error Er SC
Problem: The refrigerator temperature sensor is shorted out. The fridge doesn’t know the temperature and may freeze food. Replace the sensor inside the fridge compartment.

How to Fix Er SC Error
1. - UNPLUG refrigerator from electrical power. Pull unit away from wall for rear access.
  - Remove lower rear access panel to expose compressor compartment.
  - Locate start capacitor (cylindrical component mounted on compressor relay).
  - Discharge capacitor safely: short terminals with insulated screwdriver held by non-conductive handle.
  - Disconnect wires from capacitor terminals. Note wire positions (typically HERM, RUN, COMMON).
  - Test capacitor with multimeter in capacitance mode. Reading must match microfarad (µF) rating printed on capacitor casing (±6%).
  - If capacitor reads low, zero, or open, replace using OEM part W
  - Connect new capacitor wires to correct terminals. Secure capacitor in mounting bracket.
  - Reinstall access panel. Restore power. Listen for compressor startup within 60 seconds and verify cooling in both compartments after 2 hours.
