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 27).
3. Pull the thermocouple from the pilot assembly
(Figure 31).
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 27). NOTE: The pilot
tube should be located at the top followed by the igniter
wire then the thermocouple.
