When the MOTOR
rotates.
Check the MOTOR/Check any
interference on MOTOR rotation
①
Check CN73 -"9" Connector / Re-connect
②
Check the short/open for the SSR75 of Cover Ice Motor on Main PCB.
③
Check the resistance of parallel Connector CN73 -"9", CN70 -"11"
(Definitely plug out prior to repair)
Caution
1. When replacing the Cover Ice Motor, pull out the plug to avoid an electric shock.
2. Be careful! When disassemble the Cover Ice Motor, spring can jumped out and may cause personal injury.
3. Motor will rotate continuously when the Motor Switch is not sensed.
①
Main PCB - Check the wire OPEN/SHORT between the Cover Ice Motor Rotation sensing switches.
②
Check the Short of Cover Ice Motor Control Circuit SSR75 in the MAIN PCB.
③
Replace the MAIN PCB or the Dispenser Cover Motor.
