Basically, the thermostat itself still works, as far as we know. On our model, the part that comes inside the oven to check the oven temperature actually descends in the FRONT RIGHT side (as you face the range). And what happened is that one part--a more rigid copper (?) part that I assume reads the temperature--fell off of the wire that descends, which I assume connects to the thermostat.
So--perhaps you can suggest a way to re-connect these two pieces?
I have attached photos.....and I'd say that I am pretty handy with large-scale stuff (I have wired a whole house, for instance), but I have very little experience with appliances. So far.
