7-2. Sheath Heater
Function Sheath heater is a part for defrost. All heating wire is connected to only one line. So we can
decide part is defect or not when we check the resistance.
How to
Measure
Set a ohmmeter connect to The 2 housing pin.
Measure the 2 pin connected to Sheath Heater.
If the ohmmeter indicate (VXV)/Watt=R is good condition,
ex) when watt=350w, voltage=115v R=(115X115)/350=38 ‰
But the ohmmeter indicate infinitely great
