I don't normally do commercial stuff, but a buddy of mines oven at his restaurant is acting up.
He had a grease fire in the oven and ever since then it won't heat past about 350.
I thought it would be the thermostat control, but the oven burner stays on. It never gets hot enough for the tstat to turn it off.
I cleaned the burner and the orifice going into it. they were both clean.
Is it possible that the heat somehow screwed up the gas valve so that it is not letting enough gas in?
The oven burner flame looks small to me. They said it used to get up to 450 really quick, now it takes and hour to get to 350.
