Test Procedure F0 - Loss of safety signal.

Twelve hour off

F9 - Motorized door lock error. FF - Door motor supervision problem. DOOR - Lock status is not sensed within 90 seconds of energizing door lock relay. Touch BAKE. Touch slew until an oven temperature greater than 500° shows on display. Immediately touch and hold BAKE until “00” appears in display, approximately 5 seconds. To decrease oven temperature (for a cooler oven), touch slew until negative numbers appear. Oven can be adjusted from -5 to -35 degrees lower. To avoid overadjusting oven move temperature -5 degrees each time. To increase oven temperature (for warmer oven), touch slew until positive numbers appear. Oven can be adjusted 5 to 35 degrees higher. To avoid overadjusting oven move temperature 5 degrees each time. Touch OVEN CANCEL. Temperature adjustment will be retained even through power failure. This is a safety feature that can be used to prevent children from accidentally programming the oven. It disables the electronic oven control. Touch and hold Bake and Cook Time for 10 seconds. “OFF” will display where the temperature normally appears.

Results Verify glass to adapter board connections, replace adapter board. Replace ERC. Check sensor wiring, sensor , and temperature limiter. Check sensor resistance and wiring. Check sensor resistance and wiring. Verify glass to adapter board connection, replace glass panel. Check latch switch. Check latch switch and door motor. Verify operation of door latch switches.

While increasing or decreasing oven temperature, this does not affect selfcleaning temperature.

To reactivate the control, touch and hold Bake and Cook Time for 10 seconds. Child lockout features must be reset after a power failure. Control will automatically cancel any cooking operation and remove all relay drives 12 hours after the last pad touch.
