Oven light housing

Disconnect connector and test

Verify bulb is properly installed.

 

 

 

 

resistance of terminals

Indicates continuity with bulb installed.

 

 

 

 

Measure voltage at oven light:

120 VAC, refer to wiring diagram for

 

 

 

 

 

terminal identification. If no voltage is

 

 

 

 

 

present at light, check wiring/switches.

 

 

 

Door plunger switch

Remove switch from unit and measure

 

 

 

 

 

the following points:

 

 

 

 

 

C NO

Plunger in continuity, Plunger out infinite.

 

 

 

Autolatch assembly

Disconnect wires and test for

See wiring diagram for schematic layout.

 

 

 

with switch

continuity per wiring diagram.

Access assembly by removing left side

 

 

 

 

 

panel.

 

 

 

 

Refer to Parts Manual for correct

 

 

 

 

 

autolatch switch associated with the

 

 

 

 

 

correct manufacturing number.

Disconnect wiring and check for

 

 

 

 

 

continuity in LITE position

Continuity in LITE position.

 

 

 

Spark ignition

Test for resistance of spark lead

Continuity

 

 

 

electrode

 

 

 

 

 

 

Test ignitor to chassis

No continuity from ignitor to chassis.

5 K btu

 

 

Top surface burner

Verify gas is supplied

Check for obstructions in burner ports.

9.2 K btu

 

 

 

 

16 K btu

Check polarity and ground

See wiring diagram

 

 

 

 

 

 

 

Temperature sensor

Measure resistances

Approximately 1100 at room

 

 

 

 

 

temperature 75°F.

 

 

 

Bake burner

Verify gas is supplied.

Set for Natural Gas from the factory

 

 

 

 

Orifice adjusted for Natural or LP

Adjust as necessary.

 

 

 

 

Check for obstructions or

 

 

 

 

 

contamination in ports

Replace if punctured or torn.

 

 

 

Broil burner

Verify gas is supplied.

Set for Natural Gas from the factory

 

 

 

 

Orifice adjusted for Natural or LP

Adjust as necessary.

 

 

 

 

Check for obstructions or

 

 

 

 

 

contamination in ports

Replace if punctured or torn.

 

 

 

Ignitor

Test for voltage at terminals

120 VAC

 

 

 

 

Test for the amount of amperage in the

 

 

 

 

 

circuit

3.2 3.6 Amps If not replace.

 

 

 

 

(Ignitor may glow but not have

 

 

 

 

 

sufficient amperage to open valve).
