Question about Tappan TGF320 Gas Kitchen Range
Tappan 30-3457-00 range oven won't light. HSI measures 177 Ohms but when calling for ignition, there's no voltage across it. Electrical diagram shows a fuse block in series with the HSI. Where is the fuse block?
If that's not the problem, I suspect an open (electrically open) gas valve. It's not obvious to me how much of the oven I have to disassemble to get to the gas valve. How do I get to it?

the gas pressure regulator can whistle sometimes. turn up the radio. (just kidding) I have had some new units that did this and replaced the regulator and it still did it! I was working as factory authorized service tech and my factory techline said it was a gas pressure thing. I was thinking it was the valve rather than regulator but tech guys said no. I don't know about that response but thats what I got.

There is no way to light the oven manually. The gas valve will not open until the oven ignitor draws enough current. But replacing the ignitor will fix ya up.

SOURCE: oven controls
those failure codes usually mean the oven sensor is out of range or has an open circuit.
you can replace the sensor for about 50-75 bucks and that will allow the oven to heat properly again.
you wont need to do any reseting or clearing of the code, just fix the problem and that code will go away.

Either a weak ignitor or stuck valve. I tap on the valve with the plastic end of a screwdriver while it is glowing and if it lights the ignitor is weak. If not the valve is stuck and both should be replaced.
