I concur, but they sure aren't rheostats. If they were they'd dissipate
as much heat as the element itself when set for "half heat", and would
get hotter than hell themselves.
I'm remembering how they worked from many years ago. Back then they were
simple pulse width modulators based on thermostatic action mechanically
modified by the setting of the temperature control knob.
Do they still work on that principle guys?
Interesting. We still use old stoves, and have only very occasioanlly
replaced one of the controls.
But yes the older controls do click in and out when set to anything
other than maximum.
Agree; in the case of this OP replace the control.
Once or twice in some 50+ years have seen more sophisticated control
that incorporate a temperature sensor tube that feeds back the
temperature of the heating element to the control itself. Very rare
Not familiar with newer solid state/electronic controls but guess they
are similar to a heavy duty light dimmer-switch? Some form of triac
Better repost clarifying what you mean. It sounds as if one top burner
element (1) fails to heat when its unique control is switched on,
(2) heats when the other three controls (for three other burners) are
switched on. This seems dangerous.
That is true. The 1 and 2 settings are just for holding a little heat
in an already warm pot. It would take forever to actually raise the
heat on much with that setting but it is great if you are just keeping
dinner warm without burning the bottom of the pan.
These are also far from lab grade instruments and I doubt any of them
are the same at these low numbers.

If it bothers you, replace the control. They just plug in and they are
$10-15 at the appliance parts place.
This is really a pretty crude controller that simply uses a heated
bi-metal strip and a contact to select the duty cycle of the element.
