There are a lot of small round metal objects with two leads attached. They appear to be sensors of some kind. Do you know what these might be?

It sounds like you are describing overtemp switches, also commonly used in clothes dryers, electric space heaters, ranges, etc...

Basically used anywhere you want the heating device turned off, in
the event a predetermined "critical" temperature has been reached.

Generally, they incorporate a bimetallic switch that will switch
OFF when their rated temperature has been reached, then switch
back ON whenever the temperature has dropped sufficiently again.
