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)
Measure the 2 pin connected to Fuse-M.
If the ohmmeter indicate below 0.1ohm
Fuse-M is good. If Fuse-M measures infinite
ohms, it is open and needs to be replaced.
How to
Measure
(Sensor)
Measure the 2 pin connected to Sensor.
If the ohmmeter indicate 11
(at room
temperature) It is normal.
Checking the resistance at other
temperatures, check the sensor resistance
chart.
