Our water oven is only 2 years elderly. The pilot light keep going out. This weekend we changed the thermo couple but it still goes out. Does anyone know what else it could be?????
Answers:    Presuming you own all the Mfg. covers installed, look at correlating outages next to wind at consistent directions and speeds. What type of Cap is on the vent? Might try a different one to prevent a draft from being pushed subsidise down the stack.
Also reveiw the combustion air intake. In an sheltered area, here should be an intake vent to supply combustion air.
Using a smoke source ( incense stick, cigarette, etc), I would view how the air moves to the part.
I had similar problem merely on particular twist direction times and placed an "elbow" on my combustion air intake to switch the airflow in the utility room. Did the trick for me.
Is in attendance a draft getting to it somehow? Ours would do that every so often when the entwine changed and it was from the vault door.
