Parts information:

GWN30T pilot not staying lit or not lighting problem is commonly caused by a bad thermocouple or faulty ODS Pilot assembly. It is more cost effective to replace the ODS pilot with the new style part # 120630-01 ODS which also comes with the new style thermocouple and electrode.

When replacing the thermocouple only, you must remove the thermocouple from the pilot bracket and compare it to the chart before ordering to verify correct replacement.
NOTE: The common thermocouple used on the GWN30T heater was the 110186-01 and was held into the bracket with a hair pin style clip.

SEE PICTURE FOR THERMOCOUPLE CHART before ordering thermocouple

When replacing gas valves you must verify the model number on your gas valve sticker and match it to the model you are ordering, if they don't match contact us for assistance before ordering. You will also need to remove the min rate screw (gas mixture screw) from the old gas valve to be used in the new valve for the correct gas flow rate.
