How do I Repair a Maytag Range Model MER5770AAB With an F9 Error Fault Code?
- 1). Wait at least one hour after the oven has completed a self clean cycle to attempt to open the oven door, as the oven remains locked until the interior temperature has cooled sufficiently.
- 2). Press "Cancel" and wait a few minutes if the oven is cool and wait until at least one hour has elapsed since the completion of a self-clean cycle.
- 3). Open the oven door and check the door lock switch. Move the switch back and forth with your fingers to return the switch to the original position. Check for dirt or debris that may be causing the switch to stick or lock and clean as necessary.
- 4). Contact an authorized service technician if the problem is not resolved, as the door switch may need to be replaced.
