I live in a student housing cooperative and we have a Montague Grizzly commercial gas range that the co-op picked up from a used restaurant supply store. It is a really nice stove, but the oven likes to go out all the time.
I’d like some advice on this. We’ve had a guy come and look at it and he tried to fix it but it still doesn’t work. He replaced the valve that controls the flow of gas to the pilot and the gas ring. We replaced the thermocouple, it still doesn’t work. I’ve tried adjusting the flame level and it doesn’t seem to fix the problem.
What I would like is help on this. I’ve educated myself a bit on the workings of the oven, mostly by watching it and reading a little bit on how gas stoves tend to work. From what I’ve observed I see that the oven turns off because the valve letting the gas in closes. It only seems to happen when the pilot light isn’t touching the thermocouple. Sometimes the flame coming from the pilot light shrinks, ussually when the gas ring has been lit for a while. So I can see that this is what causes the gas to shut off, but I can’t figure out why the pilot flame slackens. Does anyone have an idea?
There seems to be a thermostat that regulates the level of the flames in the gas ring, Is this the thermocouple that also regulates the pilot light? If the flames in the gas ring are are reduced will the pilot be reduced as well?
I see from my questions that I could probably do with so more information on the structure of this oven. If someone could explain or provide me a way to find schematics on Commercial ranges that would probably help.
