I am working on a couple of year old BLODGETT pizza ovens, first one I fixed no issue. Second one has this issue.
Gas goes from pilot valve assembly down to a safety on/off switch/valve down to a thermostat type valve. This is the one you set your temp. On the good oven if you turn valve to on and the thermostat valve is all the way down it does not light until you set temp. The broken one is at full fire all the time as soon as you turn on. Seems like no control.
My question is this valve has a temp sensing bulb and the t-stat valve. are they seperate pieces or they come as one.
