How to Fix / Troubleshooting
Safety: Unplug the ice maker before accessing the control compartment.
- Power reset: Disconnect power for at least 5 minutes to allow the control to fully discharge. Restore power and see if the error clears.
- Inspect control board: Access the control board (often behind the lower front panel or rear service panel). Look for burnt components, bulging capacitors, or signs of moisture damage.
- Check harness connections: Reseat all connectors to the control board and user interface. Ensure locking tabs are engaged and no pins are bent.
- Verify proper voltage: With power on (use caution), confirm correct line voltage is present at the board input using a multimeter. If voltage is unstable, correct the supply issue.
- Replace control board if needed: If E7 returns after reset and wiring checks, replace the main control board with the correct Whirlpool OEM part.
