Maytag Range Error Code F9-6

F9-6 means the control board does not see a signal from the lower door lock switch. This fault occurs during or at the start of a self-clean cycle when the control commands the lower door to lock and receives no confirmation that the lock engaged. The problem is typically in the door lock assembly, its switch, or the wiring harness connecting it to the control.

Start by unplugging the range and inspecting the wire harness running to the lower door lock assembly. Look for loose connectors, pinched wires, or visible damage. If the harness is intact, test the lock switch for continuity with a multimeter. A switch that does not show continuity when the lock is engaged needs replacement. If the switch and harness both pass, test the lock motor for proper operation. Replace whichever component fails testing.

Clearing the code by cycling power will remove the displayed error, but the fault will return the next time the control attempts to engage the lower door lock. The underlying issue with the lock switch, harness, or lock assembly must be diagnosed and repaired for the error to stay clear. Do not use clearing the code as a workaround while continuing to attempt self-clean cycles.

Normal baking and broiling functions are generally not affected by F9-6 because the door lock is only required during self-cleaning. However, you will not be able to run a self-clean cycle until the fault is resolved. Do not attempt to bypass or override the door lock circuit, as the self-clean cycle reaches temperatures above 800 degrees Fahrenheit and requires a secured door.

A replacement lower door lock assembly typically costs between $40 and $120 depending on the specific model, and the repair is accessible for a confident DIYer with basic hand tools and a multimeter. If you hire a technician, expect an additional $100 to $200 in labor depending on your area. Checking and reseating the wire harness connectors costs nothing beyond your time and should always be the first step before purchasing parts.
