11-2 Sheath Heater
Function Sheath heater is a part for defrost. All heating wire is connected to only one line. To check if
the part is defective, 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 (V°øV)/Watt=R is good condition,
ex) when watt=350w, voltage=115v R=(115°ø115)/350=38
Ω
But if the ohm meter indicate infinity the Sheath heater is bad.
