What Does Error ERR6 Mean?

The Whirlpool Microwave ERR6 indicates an abnormal weight sensor reading, often causing the microwave to stop cooking or fail to start when the weight sensing function is active. This error may also come with unusual buzzing or humming sounds and typically persists even after power cycling. The issue may stem from a faulty or miscalibrated weight sensor, wiring problems, or an incorrect interpretation of sensor data by the controller.

Common Symptoms:

  • Microwave displays ERR6 on the control panel
  • Microwave stops cooking or refuses to start when weight sensing function is active
  • Error persists after normal power cycling

Possible Causes

  • Faulty or miscalibrated weight sensor (medium)
  • Wiring issue between the weight sensor and appliance controller (medium)
  • Controller (appliance manager) not interpreting sensor data correctly (medium)

How to Fix Error ERR6

DIY Fix Perform basic reset and check connections

  1. Unplug the microwave from power for at least one minute.
  2. Plug the microwave back in and see if the ERR6 code clears.
  3. Ensure that the unit is placed on a level surface and the weight sensor area (if visible) is not obstructed.

Technician Only Inspect and repair/replace weight sensor and related wiring

  1. Disconnect power and remove the microwave’s outer cover following manufacturer safety procedures.
  2. Visually inspect the weight sensor and associated wiring harness for damage or loose connections.
  3. Test the sensor’s output with appropriate diagnostic equipment to verify abnormal readings.
  4. Replace a defective weight sensor or repair damaged wiring.
  5. If sensor and wiring are intact, test the appliance manager/control board input for correct interpretation of sensor data.

Parts needed: Weight sensor module, Sensor wiring harness, Control board (if needed after sensor testing)

🛑 When to Call a Pro:
  • If the error persists after basic resets and checking visible connectors
  • If you are not trained to safely inspect internal components or handle electronics
  • If multiple error codes appear simultaneously
