INSTRUCTIONS

1. Disconnect power or unplug microwave.

2. Remove the grill.

3. Remove control panel.

4. Locate cavity thermostat (see Figure 1), and remove the
thermostat mounting screw. (Be careful not to lose
screw.)

5. Using screw removed, mount SURGE RESISTOR and

THERMOSTAT. See Figure 1.

6. Remove tape backing on relay. See Figure 2.

7. With screw provided in kit, mount the relay into hole
