10-4 L-cord Heater (Refrigerator Room)
Function L-cord heater is the part for defrost. All heating wire is connected to only one line. So we can
decide part is defective or not when we check the resistance.
How to
Measure
Set a ohmmeter connect to The housing pins.
Measure the pins connected to Sheath Heater.
If the ohmmeter indicates (VxV)/P=R (V=voltage, P=Watt, R=Resistance) is on a good condition,
ex) watt=130W, voltage=120V R=(120x120)/130=111
Ω
Infinitive value implies sheath heater is disconnected.
