Interlocks (Door Latch Switches)

The interlocks are designed as follows:

Primary - Bottom switch operated by bottom latch pawl connected to line (L) leg.

To test the interlocks:

1.Disconnect power to the oven.

2.Open the control panel.

3.Discharge the capacitor.

4.Check continuity of COM and N.O.:

Door Closed - 0 Ω

Door Open - ∞ Ω

Monitor Switch

The monitor switch is located between the top and bottom interlocks. The monitor switch is operated indirectly by the bottom latch pawl.

To test the interlock system:

1.Disconnect power to the oven.

2.Open the control panel.

3.Discharge the capacitor.

4.Disconnect the monitor switch leads and test at the terminals:

Door Closed - ∞ Ω

Door Open - 0 Ω

5.Reconnect the switch wiring.

6.Test the circuit operation:

a.Connect temporary jumper across relay contacts and primary switch to simulate shorted switch contacts. Locate convenient connections in circuit to be certain COM and N.O. terminals are used.

b.Connect an ohmmeter (Low Scale) across the two line terminals of the appliance power cord. Continuity must show:

Door Closed - Some Ω

Door Open - 0 Ω

c.Remove the 20-Amp. fuse - the circuit must open (∞ Ω). If not, check the wiring of the monitor and interlock circuits.

7.After the test, remove temporary jumper leads from interlocks and relay. Reconnect monitor switch leads, replace fuse.

8.Replacement of any parts in monitor circuit requires repeating this entire test procedure.

The switch housing is not adjustable. It is fixed on the front cavity with two screws.

IMPORTANT - CHECK FOR MICROWAVE LEAKAGE AFTER REPLACING OR ADJUSTING DOOR, INTERLOCK SWITCHES OR BRACKETS.
