THE BIMETAL SWITCHES

There are two bimetal switches on the electric range. The switches operate as follows:

•Ambient Bimetal Switch (N.C.)

(Inset #1) —This switch is located un- der the left side of the control console. It opens the L1 circuit to the electronic control board if the console temperature reaches 96˚C/205˚F.

•Cooling Fan Bimetal Switch (N.O.) (Inset #2) —This switch is located un- der the right side of the control console. It turns the cooling fan on if the console temperature reaches 70˚C/158˚F.
