WARNING
ERC Voltage Tests
1. Turn off power to the range. Partially remove ERC
from control panel.
2. To verify input voltage for vacuum fluorescent display,
insert AC voltmeter leads into pins J1–1 and J1–2,
and turn power on. A voltage reading of
approximately 3.2 VAC should be indicated. If no
voltage is indicated, check for loose connections,
open wire(s), and relay/power supply circuit board
output voltage at pins J1–7 and J1–8 on relay board.
3. To verify input voltage that the ERC uses to drive
bake/broil relays, insert AC voltmeter leads into pins
J1–3 and J1–4. A voltage reading of approximately
20.3 VAC should be indicated. If no voltage or a low
voltage reading is indicated, check for loose
connections, open wire(s), and relay/power supply
circuit board output voltage at pins J1–5 and J1–6 on
relay board.
4. To verify bake relay drive voltage, insert DC voltmeter
leads into pins J1–5 and J1–9, and program ERC for
a bake operation.
When ERC initiates the bake operation, a voltage
reading of approximately 24 VDC should be
indicated. If no voltage is indicated, check for input
supply voltage at pins J1–3 and J1–4 (step 3).
To verify broil relay drive voltage, insert DC voltmeter
leads into pins J1–5 and J1–8, and program ERC for
a broil operation. When ERC initiates broil operation,
a voltage reading of approximately 24 VDC should be
indicated. If no voltage is indicated, check for input
supply voltage at pins J1–3 and J1–4 (step 3).

To avoid possible electrical shock, personal injury, or death,
disconnect power and turn off gas supply before servicing,
unless testing requires it.
ERC Failure Codes and Warnings
Electronic range control is capable of detecting certain
failures within the ERC, oven temperature sensor, and
self-clean latch switch. Failure codes and warnings which
may appear on the display include F1 through F8, "door"
or "lock". A brief description of the failure codes or
warnings is listed below.
F1 - Indicates a failed component in the ERC.
F2 - Sensor resistance too high. Check sensor resistance,
wire harness and connections.
F3 - Open wire lead in sensor harness, failed 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. Verify the function
buttons are not binding on the control panel—reposi-
tion the ERC. Verify function buttons spring outward
after being depressed.
F8 - Indicates a failed component in the ERC.
"Lock" Light On—If "lock" appears in the display when
oven is not set in clean mode, 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 failed latch switch or shorted wire lead
from the ERC pin J1–10 to ground, or door latch is set to
clean or locked position.
"Door" appears in display—In clean mode, this is an
indication of a failed latch switch or an open wire lead
from the ERC pin J1–10 to ground, or door latch has not
been closed as required to initiate clean cycle.
Touch Tone Deletion
With touch tone activated, a "beep" is audible whenever
any one of 8 push pads are depressed on ERC.
To delete the touch tone "beep" depress and hold the
CANCEL push pad for five (5) seconds.
To restore the touch tone "beep" depress and hold the
CANCEL push pad for five (5) seconds.
