DO NOT use a wire or pin when cleaning the burner jet
as damage can occur to the precision opening. This can
cause damage to the refrigerator or create a fire hazard.
10) Reinstall burner, being careful that the end of the
burner fits into the slot on the burner bracket. Check
to make sure slots are centered under the flue tube
and the thermocouple is positioned properly (tip of
thermocouple extends over two slots of burner).
