10. COMPONENT TESTING INFORMATION

10-1 Defrost Controller Assembly
Function - Controller assembly is consist of 2 kinds of part those are fuse-m and sensor. we can
decide part is defect or not when we check the resistance.
- Fuse-m can cut off the source when defrost heater operate the unusual high temperature.
- Sensor give temperature information to Micom
How to

(Fuse-M)
How to
Measure
(Sensor)
Standard
(1) to (2)
(1) to (2)
Fuse-M (at all temperature)
Test Point Ressult
(1) to (2) 0 ~ 0.1Ω
Set a ohmmeter to the 2 housing pin.
Measure the 2 pin connected to Fuse-M.
If the ohmmeter indicate below 0.1ohm
fuse-m is a good condition, But infinitely
great ohm Fuse-M is disconnection
Set a ohmmeter to The 2housing pin.
Measure the 2 pin connected to Sensor.
If the ohmmeter indicate 11㏀ (at room
temperature) Sensor is not a defect.
When check the ohm at other temperature
Check the sensor manual.
