7-1. 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

Fuse-M (at all temperature)
Test Point Ressult
(1) to (2)
0 ~0.1 ‰
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 11k‰
(at room temperature)
Sensor is not a defect.
When check the ohm at other
temperature Check
the sensor manual.
