Caution: Conduct this test with the
refrigerator unplugged. Test the mold heater for resistance using
a multitester.
Set the multitester to the ohms setting X1. Place one probe into
the hole labeled "H" and the other probe into the hole
labeled "L". The multitester should read in the range
of 60 to 90 ohms.
If you get a significantly different reading, such as zero or
infinity, then the mold heater is bad and needs to be replaced.
