Blodgett oven mark v 111 can cool down but not cooking

SOURCE: blodgett oven

if you only have 3 wires to the element it doesnt matter how there hooked up.

SOURCE: large yellow flame, not cooking food thoroughly

I think ill give it a try for you. The gas lines come in thru you cutoff valve then thru you gas valve and on to the burner. right before the burner you will see a bell shape fitting. The gas line is in the center of the fitting and there will be some opening around this fitting That fitting has dust clogging it up. This is where the gas mixes with the air Turn your oven off and blow this fitting out.
