7-1. Defrost Controller Assembly
7. COMPONENT TESTING INFORMATION
- 44 -
(1) to (2)
(1) to (2)
- 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
Function
How to
Measure
(Fuse-M)
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
How to
Measure
(Sensor)
Standard
Set a ohmmeter to The
2housing pin.
Measure the 2 pin
connected to Sensor.
If the ohmmeter indicate 11kΩ
(at room temperature)
Sensor is not a defect.
When check the ohm at other
temperature Check
the sensor manual.
