Suburban SRSA3LBBE oven goes out

Clean around the pilot and burner area first.

Well, it sure seems like yours does have a thermocouple for some purpose in that case.

I might try watching it while manipulating the control knob to see if I could catch it in the act of misbehaving; maybe that would give some clue as to what's going on. I kind of doubt it's the thermocouple, assuming it's being used as a safety for the pilot, since I would expect it to be heated more when the main burner is burning rather than less. I would tend to expect trouble with it to mainfest itself more in the pilot not being able to be lit or not staying lit when sitting and the main burner isn't yet on. I'm by no means an appliance expert, however.

Does it even have a thermocouple for the pilot? Not all ovens do. One common design has a teeny pilot that grows when the thermostatic valve calls for heat, and heats up a bulb for a safety valve that allows the gas to flow to the main burner. When the temperature is reached, the thermostatic valve shuts off the gas to the burner and the extra gas for the pilot and it dwindles back down to a tiny pilot (and the safety valve closes again once its bulb cools off).

I would guess that the pilot burner needs cleaning or adjusting. It sounds like it's getting blown out in the process of the main burner shutting down. Perhaps there's supposed to be a baffle or something that's out of place or has crud in the way or or something.

The parts list includes a thermocouple. That's where I got the idea it might be the problem.
