4-2-14. If Cover Ice Route Motor(Geard Motor) is not working normally
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.
☞ Checking Mehod of Cover Ice Route Motor
(Make sure to work after Power Off)
the voltage of Resistance is variable
according to the input voltage.
CN70 -"5" (Red) ↔ CN73_1 -"3" (Blue)
** 0Ω: Short trouble / Ω∞: Open trouble
When the MOTOR
① Check CN73_1-"3" Connector / Re-connect
② Check the short/open for the SSR75 of Cover Ice Motor on Main PCB.
③ Check the voltage of Resistance of parallel Connector CN73 -"3",

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.
