Disassembly Procedures

!WARNING

To avoid the risk of electrical shock, personal injury, or death, disconnect power to oven and discharge the capacitors before following any disassembly procedure.

Adjusting Interlocks

The interlock monitor, primary, and secondary switches act as a final safety switch, protecting the operator from microwave energy. After adjusting the interlock switch assembly, verify wires are correctly connected.

For door fit and switch operation, switch bracket is adjustable.

1.Disconnect power to oven and remove outer case, (see "Outer Case" procedure).

2.Loosen switch bracket mounting screws.

3.Close oven door, move switch bracket toward rear of oven until door gap is less than 1/64–inch (0.5 mm).

4.Hold switch bracket securely for proper switch operation and door fit, retighten screws.

5.Open oven door slowly, watching the switches. Verify switches release in the following order.

Primary interlock switch

Secondary interlock switch

Interlock monitor switch

NOTE: Adjust the switch bracket until all switches operate in proper sequence.

6.Close the oven door slowly, watching the switches. Verify switches activate in the following order.

Interlock monitor switch

Secondary interlock switch

Primary interlock switch

7.When proper switch sequence has been achieved, tighten the switch bracket securely.

!CAUTION

A microwave leakage test must be performed anytime a door assembly is removed, replaced, disassembled, or adjustment of switch bracket is performed.

High Voltage Capacitor

High voltage capacitor should always be discharged by shorting a terminal to a chassis ground. The capacitor has a internal "shunt" resistor, but the mechanical discharge should always be performed to avoid personal injury.

Bottom Magnetron High Voltage Capacitor Removal

1.Disconnect power to oven and remove outer case, (see "Outer Case" procedure).

2.Discharge high voltage capacitor.

3.Remove and label wire leads from capacitor terminals.

4.Remove screw securing diode to ground.

5.Remove screw securing capacitor strap to the back panel, located on the back panel.

6.Slide capacitor out of capacitor strap and remove capacitor.

7.Replace capacitor and reverse procedure to reassemble.

NOTE: When replacing H.V. components, route H.V. wires at least 1/4" / 6 mm from all grounded surfaces to prevent arcing.

Top Magnetron High Voltage Capacitor Removal

1.Disconnect power to oven and remove outer case, (see "Outer Case" procedure).

2.Discharge high voltage capacitor.

3.Remove and label wire leads from capacitor terminals.

4.Remove screw securing diode to ground.

5.Remove screw securing top portion of capacitor strap to the top of the oven cavity.

6.Remove screw securing control panel to chassis.

7.Raise control panel upward and rotate to the side to gain access to capacitor bottom mounting screw.

8.Remove screw securing bottom portion of capacitor strap to the duct assembly.

9.Slide capacitor out of capacitor strap and remove capacitor.

10.Replace capacitor and reverse procedure to reassemble.
