OPERATION AND SERVICE PROCEDURES

either timer switch contacts 1 to 2 or 3 to 4. Press "SET" button twice (Auto Program) and rotate "SET" knob for approximately ten (10) to fifteen (15) sec- onds. Meter needle should swing to zero (0) ohms (continuity) indicating a closed switch. Repeat the procedure after transferring the test leads to the other switch contacts. Allow countdown to complete, the alarm should sound, and the meter indicate open contacts. NOTE: A slight "click" can be heard whenever the relay switches open or close.

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

BAKE AND BROIL IGNITORS

The bake and broil ignitors are mounted to the bake and broil burners and ignite the gas flowing into the burner. During a broil or manual bake operation, current flows through the ignitor, gas valve, selector switch, and thermo- stat to neutral. As the ignitor starts heating up and glowing, its internal resistance decreases allowing more current to flow through the bake or broil circuit. When the circuit current reaches approximately 3.2 - 3.6 amps, the bi-metal arm in the gas valve flexes, opening the valve, allowing gas to flow to the burner where it is ignited by the glowing ignitor. The ignitors will glow anytime the bake or broil burners are in operation and cycle on and off with the thermostat cycling contacts.

The operation of the OVEN/BROILER "ELECTRIC IGNI- TOR" can be checked by using a VOLT/OHMMETER as follows: NOTE: This check must be made while the ignitor is at ambient room temperature.

1.Disconnect electricity.

2.Set the volt/ohmmeter on the RX1K ohms scale. (Zero the meter.)

3.Remove ignitor from burner.

4.Remove ignitor lead wire nuts and disconnect ignitor leads from range wiring.

5.Connect ohmmeter leads to ignitor wire leads.

6.If the meter indicates continuity (a low resistance reading), the ignitor is operative. NOTE: The cold resistance measurement can vary several hundred ohms. However, this test is for continuity without a dead short (zero ohms).
