OPERATION AND SERVICE PROCEDURES

TO AVOID THE RISK OF ELECTRICAL SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER BEFORE SERVICING, UNLESS TESTING REQUIRES IT.

Figure 65

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.)

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.
