DOOR LATCH ASSEMBLY

Description

The purpose of the door latch is to lock the oven door during the self-clean cycle. The door latch assembly consists of a solenoid and a switch.

The latch assembly prevents the oven door from being opened during the self-clean cycle, when the oven temperature is above 600˚F.

The door latch solenoid operates on a 120-volt dc pulse from the oven control. When the door is in the unlocked position, the solenoid plunger is extended. When the latch sensing switch is open, the control senses that the door is un- locked. When the latch sensing switch closes, the oven control senses that the door is locked. The latch sensing switch, mounted on the solenoid bracket, is in the N.O. (normally- open) position. During the self-clean cycle, the oven control sends a 120-volt dc pulse to the solenoid windings, which pulls the plunger in, and moves the latch actuator rod to lock the oven door. The movement of the rod also activates the latch sensing switch and closes it. When the self-clean cycle is over, and the oven temperature reaches approximately 600˚, the oven control sends a 120-volt dc pulse to the solenoid, the plunger is pushed out, the latch actuator rod releases the door and un- locks it, and the sensing switch opens. There are no adjustments for the latch.

Test Procedure

WARNING

Electrical Shock Hazard

Disconnect from electrical supply before ser- vicing unit.

Failure to do so could result in death or electrical shock.

Door Latch Solenoid

TERMINALS

SOLENOID

 

To test the solenoid windings, perform the following steps:

1.Use an ohmmeter and set the range switch to R x 1.

2.With no power applied, remove the wire from either solenoid terminal.

3.Touch the leads of the ohmmeter to the

terminals of the solenoid. You should ob- tain a reading of between 45 and 65.

If the reading is not within the range shown, the solenoid is defective and should be re- placed.

Latch Sensing Switch

NCTERMINALS

NO

COM

SWITCH

To test the latch sensing switch, perform the following steps:

1.With no power applied, touch the ohmme- ter leads to the two switch terminals. The

meter should indicate an open circuit (in- finity ).

2.Close the switch and the ohmmeter should indicate 0 (short circuit).

If the above results are not obtained, the switch is defective and should be replaced.
