INSPECTION
• Check the thermo-switch closing or opening temperatures by
testing it at the bench as shown in the figure. Connect the
thermo-switch to a circuit tester and place it in the oil contained
in a pan, which is placed on a stove.
• Heat the oil to raise its temperature slowly, and read the col-
umn thermometer when the switch closes or opens.
