Testing Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death; disconnect power to unit before servicing.

Oven Door Switch

Clean Safety/Light Switch (Power Off)

1.The switch has NO (normally open), NC (normally closed), and C (common) contacts.

2.Check the switch with an ohmmeter between C and NC with the plunger out. Continuity should exist. With the plunger in, no continuity.

3.Check the switch with an ohmmeter between C and NO with the plunger in. Continuity should exist. With the plunger out, no continuity.

CNC

NO

NOTE: When facing the range, the switch is on the left.

Oven High Limit/Fan Switch

Oven high limit is located on the rear of insulation retainer and connecting to the L2 side of electric supply, this switch is normally closed but will open if external temperature exceeds 260°F or 115°F, see chart below. Fan limit switch is located on the right side of insulation retainer.

1.Turn off power to range.

2.Remove oven from wall cutout.

3.Remove screws securing outer cabinet top shield to outer cabinet wrapper shield.

4.Disconnect wires from switch terminal connections.

5.Attach ohmmeter leads to switch terminals. At ambient room temperature (70°F.) continuity should be indicated.

Oven Temperature Sensor

The oven temperature sensor can be checked by using the "Quick Test Mode" covered in this section of manual or detail testing can be accomplished as follows.

The oven temperature sensor is mounted in the oven cavity and electrically connected to the ERC. Following is approximate resistance.

75°F—1082 ohms 350°F—1656 ohms 550°F—2056 ohms 880°F—2686 ohms

Sensor resistance can be checked by removing the sensor interconnect harness plug from the ERC and inserting ohmmeter leads into the harness connector plug. A resistance reading of approximately 1100 ohms should be indicated at ambient room temperature (75°F.). If a higher resistance is indicated then remove sensor from oven, disconnect sensor from harness at plug, and recheck sensor resistance to assure that the problem is in the sensor and not in the interconnect harness or due to a bad connection.

NOTE: Sensor resistance will increase if held in your hand.

Blower Motor

Fan may come on at any time to cool components down.

1.Turn off power to oven.

2.Remove oven from wall cutout.

3.Remove screws securing outer cabinet top shield to outer cabinet wrapper shield.

4.Disconnect wires from motor terminal connectors.

5.Attach ohmmeter leads to terminal tabs on motor.

6.A resistance of ohms should be indicated but may vary with each motor tested. This test is to check the motor winding for an open or shorted winding. If zero or infinite ohms is indicated, the motor winding has failed and the motor must be replaced.
