OPERATION AND SERVICE PROCEDURES

Electronic Range Control (ERC) (Models w/Two Piece Control)

ERC FAILURE CODES AND WARNINGS

The Electronic Range Control is capable of detecting certain failures within the ERC, the oven temperature sensor and the self-clean latch switch.

The failure codes and warnings which may appear on the display include F1 through F8, "DOOR", or "LOCK". A brief description of the failure codes and warnings is listed below:

F1 - Indicates a failed component in the E.R.C.

F2 - Sensor resistance too high. Check sensor resistance, wire harness, and connections.

F3 - Open wire lead in sensor harness, bad harness/ sensor connection or sensor resistance too high.

F4 - Sensor resistance too low (below 500 ohms). Check for a short in sensor wire harness and check sensor resistance.

F5 - Indicates a failed component in the ERC.

F6 - Indicates a failed component in the ERC or due to fluctuations in 60 Hz power source.

F7 - Indicates a shorted or sticking contact in one or more of the function control switches. Make sure the function buttons are not binding on the control panel glass - reposition the ERC and/or glass. Make sure the function buttons spring outward after being de- pressed.

F8 - Indicates a failed component in the ERC.

F9 - Door Latch Supervisory (Door latched):

Sounds alarm and resets control to non-cook mode if the door latch supervisory logic fails for a sample period of 2 seconds (while the door is latched). Unlatching the door (if not locked) and Cancel Key may reset the display code and audible. If the door is locked (temp > 500°F) power must be removed until the oven door can be unlatched.

"LOCK" LIGHT ON - If "LOCK" appears in the display when the oven is not set in clean mode, the oven sensor resistance is too high. Check sensor resistance, wire harness, and connections.

"DOOR" APPEARS IN DISPLAY IN BAKE/BROIL MODE

-This is an indication of a defective latch switch or shorted wire lead from the ERC pin J1-10 to ground, or door is latched.

"DOOR" APPEARS IN DISPLAY DURING CLEAN MODE

-This is an indication of a defective latch switch or an open wire lead, from the ERC pin J1 - 10 to ground, or that the door latch has not been closed as required to initiate the clean cycle.

ELECTRONIC RANGE CONTROL TEMPERATURE CALIBRATION

The ERC incorporates ± 35°F. calibration capabilities. Follow the procedures below to calibrate the ERC.

1.Press and release the "BAKE TEMP." function but- ton.

2.Rotate the "TIME/TEMP. SET" knob clockwise until a temperature between 500° - 550° is displayed. Quickly, before the ERC initiates the bake function, press and hold the "BAKE TEMP" function button. After ap- proximately four (4) seconds, the display will show "00" or the offset temperature that was previously programmed into the ERC.

3.Rotate the "TIME/TEMP. SET" knob to show the desired offset temperature in the display (up to ± 35°F. in 5° increments, "+" to set oven temperature higher and "-" to reduce oven temperature. NOTE: An accurate temperature test should be performed before calibrating the ERC.

4.Press the "CLOCK" function button to enter the offset temperature into the ERC. The calibration adjust- ment will remain programmed into the ERC even if power is removed from the ERC or range. NOTE: Self-clean temperatures are not affected by this calibration.

If oven temperature testing reveals that a calibration in excess of ±35°F. is required, the oven temperature sensor, sensor wire harness, and wire harness/sensor connections must be checked before replacing the ERC. A resistive connection within the sensor har- ness will affect oven temperature.
