Yes, that model has a sensor for one element which works in conjunction with the switch for that particular unit. The switch for it will not operate properly without a functioning sensor in place.
If needed the sensor is still available (although expensive) however the switch has been discontinued but I did find one new-old stock one up for auction on eBay (see the following links). It might be the last one in existence?

If fiddling with the switch's buttons allowed the element to sometimes work, that
might point more to a possible problem in the switch itself than in its sensor or the temperature dial switch.
BTW. I believe the sensor should measure in the area of 17.5 ohms resistance which will change depending on the temperature it is sensing at the time.
