THERMAL CUTOFF

Refer to page 4-2 for the procedure for servic-
ing a thermal cutoff.
1. Unplug the refrigerated range or discon-
nect the power.
2. Set the ohmmeter to the R x 1 scale.
3. For the thermal cutoff (N.O.) with the
narrow (3/16") terminals, touch the ohm-
meter test leads to the terminals. The
meter should indicate an open circuit (in-
finite).
4. For the thermal cutoff (N.C.) with the
