ZET1PM1SS General Electric Wall Oven - Overview

Hi Patrick, Thank you for your question. The F9 error code is letting you know that the electronic control board has sensed an issue with the door lock. This may result from an issue with the electronic control board, a jammed door lock, an issue with the wires connected to the lock, or a malfunctioning lock switch. You will need to inspect these parts to see which one is causing the issue. To verify of the lock is working correctly, you will need to test it for continuity with a multimeter. Set your multimeter to Rx1 and ensure the switch is turned to the “clean" position. Using the probes, touch the terminals of the switch, this should produce a reading of zero or nearly zero. If your test results show that there is no continuity, you will need a replacement door lock switch. To verify if the issue is with the electronic control board, you will need to inspect it for signs of damage, wear, or scorching or burn marks. If it shows any of these signs, it will need to be replaced. We hope this helps! If you have any questions, please let us know.
