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.
Set a ohmmeter connect to The 2 housing pin.
Measure the 2 pin connected to Sheath Heater.
If the ohmmeter indicate (V°øV)/Watt=R is good condition,
ex) when watt=350w, voltage=115v R=(115°ø115)/350=38Ω
But the ohmmeter indicate infinitely great
