Possible Causes

Faulty internal load or current sensor, Corrupted control software, Sensor wiring issue, Incorrect calibration data

How to Fix / Troubleshooting

Safety first: Disconnect power before internal inspection.

  • Step 1 – Verify manual modes: Confirm that manual time and power level cooking work correctly. If only auto functions are affected, the issue is likely with sensing or software.
  • Step 2 – Reset control: Unplug the microwave for 10 minutes to reset the control board. Restore power and test auto functions again.
  • Step 3 – Avoid overloading: Ensure you are using appropriate cookware and food quantities as specified in the manual for sensor and auto-defrost programs.
  • Step 4 – Professional service: If E19 persists, a technician may need to update or replace the control board and verify any internal sensors used for load detection.
