The oven does not get to the temperature called for. I removed the temp sensor and tested it. I read here that it should read less than 1100 ohms at room temp, that they average 1084 ohms. Mine reads 1101. When placed in boiling water it rose to 1360 ohms.

Is this a significant difference? Does it sound like the sensor is bad or is the problem somewhere else?

Thanks

No.
Depends how much your oven temperature varies from set point.
Each degree of temperature is 2 ohms of resistance change.

I would say somewhere else.

Most units let you calibrate the oven temperature plus/minus 35 degrees.

Thanks. So if it's not the sensor itself but the control panel thinks that it's already 200 degrees within seconds of setting the temp, would that mean it's the control panel itself? Is that a pretty expensive part?
I also see a "harness, sensor" part in the control panel diagrams but it seems like that part is discontinued.

It shows the control board (item 2 in Section 2) and a control electric (Item 15 in Section 2) which I think is just the control relays and a power supply.

I could not find a wiring diagram for this unit so am not sure how the unit is wired.
If the sensor connects into the control board then that would be the one to change.

I would unplug the unit and the sensor and check the board for any sign of a bad connection, cold solder joint etc.
Check that the connecting pins are clean.
Check for a cold solder joint. They are often a duller gray or may have pin holes.
Wiggle the connector side on the board while looking at the solder side to see if the component leg moves in the solder.
If all OK then the board would be at the top of my list.
