Testing Procedures

!WARNING

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

Auto Latch Motor

Do not remove latch motor from latch assembly. If latch motor is defective, replace latch assembly.

1.Disconnect power.

2.Slide oven out from wall cutout approximately 6 inches to gain access to control panel screws.

3.Remove screws securing control panel to unit, and pull control panel out of unit to gain access to latch assembly.

4.Disconnect lead wires from latch motor.

5.Connect jumper cord leads to latch motor.

6.Connect jumper cord to 110 AC power source.

7.Replace if latch motor fails to operate.

8.Reverse procedure to reconnect.

Convection Fan Motor

1.Turn off power to oven.

2.Remove oven from wall cutout.

3.Remove access fan plate to gain access to convection fan motor.

4.Disconnect wires from motor terminal connectors.

5.Attach ohmmeter leads to terminal tabs on motor.

6.A resistance reading of 15-30 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.

Door Latch Assembly

Auto Latch Switches

Both unlock and lock door latch switches may be replaced.

1.Perform steps 1 through 3, from “Auto Latch Motor”.

2.Disconnect lead wires from door latch switch (unlock).

3.Set ohmmeter to the RX1 scale.

4.Attach meter leads to door latch switch (unlock).

5.Depress actuator arm. The meter should read continuity.

6.Reverse procedure to reconnect.

7.Use the same procedure to test the door latch switch (lock).
