11. Pull up the microswitch bracket until is sits against the underside of the insulation (as far as it will travel).
12. Screw the interlock adjuster to begin closing the switch actuator.
13. As soon as the secondary door switch (SW2) closes, nip up the two flange head screws to 2.1Nm.
14. Tighten the interlock adjuster locking nut against the bracket using a 7mm spanner to 1Nm.
15. Remove the spacers, then open and close the appliance door a few times to validate the door switches operate in the
correct sequence.
16. Once the panels have been refitted, conduct a microwave leakage test.
