The ignitor may still be defective even though conti-
nuity is indicated and it glows when the oven is set for
bake, broil, or clean function. A more exact test can
be made to measure the ignitor current with the oven
operating. An ammeter should be inserted in series
with one (1) lead of the ignitor or an amprobe can be
attached to the lead to check the amount of current
flowing through the ignitor circuit. With the oven
turned on and the ignitor glowing red, a current
reading of approximately 3.2 - 3.6 amps should be
indicated. The ignitor can also be removed and
bench tested, using the current test method and an
AC jumper or test cord connected to the ignitor leads.
ELECTRIC GAS VALVE
The bake and broil dual gas valve supplies the gas flow to
the bake or broil burners. The valve contains bi-metalic
arms attached to the valve seats and are wound with a
small electric heater coil. When a current range of
approximately 3.2 - 3.6 amps flows through the bake or
broil circuit, the bi-metalic arm is heated causing it to flex
or bend, allowing gas to flow to the burner where it is ignited
by the burner ignitor. The gas valve is located behind the
storage drawer.
ELECTRIC GAS VALVE TEST WITH VOLT/OHM
METER
1. Disconnect electricity. (Disconnect plug or power
cord.)
2. Remove the two (2) wire terminals from Point A for
testing "BAKE" portion of gas valve or Point B for
testing "BROIL" portion of gas valve.
3. Set volt/ohmmeter on the RX1 ohms scale (zero (0)
the meter).
4. Attach a meter lead to each of the terminal studs on
the portion of the valve to be tested.
TO AVOID THE RISK OF ELECTRICAL SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER
BEFORE SERVICING, UNLESS TESTING REQUIRES IT.
5. If the meter does not show an "OPEN" circuit, the gas
valve is operative.
6. Reattach the two (2) wire terminals removed from
Point A or Point B on the gas valve.

SELECTOR SWITCH
The selector switch is a two (2) position switch used for
"MANUAL" or "AUTOMATIC" bake operation. The selec-
tor switch contacts can be checked for continuity by using
a continuity tester or an ohmmeter set to the low ohms
range and following the selector switch contact chart.
Power to the oven must be turned off and the selector
switch wiring removed when checking the contacts for
continuity. Access to the selector switch contacts can be
made by removing the control panel. NOTE: The selector
switch is not found on models with the ERC.
