11. COMPONENT TESTING INFORMATION
11-1 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
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)
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.
Standard
Sensor (at room temperature)
