Honeywell Gas Valve

Post by Nashman01 » Fri Dec 25, 2015 11:04 am

This morning my hot water boiler burners only had about a 20% blue flame. Boiler water temperature was down to 100F.
I observed that the control knob on the gas regulator was 1/2 way between on and pilot. I rotated it to the on position and the burners came full on and the water temperature went back to normal (190F). My question is how did it rotate our of the on position all by it self ? Is the unit defective and should it be replaced. I replaced the thermocouple about 4 months ago in the summer. Or, did I not get it in a good solid on position?

I wouldn't worry why the gas valve wasn't in the ON position. However, I would periodically check it to make sure it stays in the ON position. If you find the ON/PILOT/OFF knob has moved, post back here for exorcism instructions.
