Replacing the Thermocouple
1.Remove the Burner Door Assembly as directed previously.
2.Remove the retainer clip from the back of the two piece wire connector and remove the two piece wire connector from the assembly (Figure 25).
3.Pull the thermocouple from the pilot assembly (Figure 29).
IMPORTANT: Be careful not to bend or alter the position of the pilot assembly components.
4.Push the new thermocouple through the holes in the pilot bracket. Insert the thermocouple tube into the holes provided in the pilot assembly until it clicks into place. Leave a small straight section entering and leaving the two piece wire connector section for easier removal/service.
5.Position the new thermocouple through the opening of the two piece wire connector (Figure 25). NOTE: The pilot tube should be located at the top followed by the igniter wire then the thermocouple.
