OPERATION AND SERVICE PROCEDURES
Electronic Range Control (ERC) (Models w/Two Piece Control)
RC231002 Rev. 3 40
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.
