Bimetals; Single Element Infinite Switches (Rf, Rr, Lr) - Whirlpool Polara GR556LRK Service Manual

Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
BIMETALS (N.C.)
Refer to page 4-33 for the procedure for servic-
ing the bimetals.
1. Unplug the refrigerated range or discon-
nect the power.
2. Set the ohmmeter to the R x 1 scale.
3. Touch the ohmmeter leads to the bimetal
connector pins. The meter should indicate
a closed circuit (0 Ω). If the reading indi-
cates an open (infinite) circuit, replace the

bimetals.

IMPORTANT:The bimetal marked (F36-18F)
must be mounted below the other bimetal. The
bimetals will be replaced as an assembly.
