IM-50BAA-LM
This appliance uses a lever-actuated microswitch to control the ice level in the storage
bin. No adjustment is required.
To check, follow the steps below.
1) Remove the front panel and then move the control switch to the "OFF" position.
2) Unplug the appliance.
3) Remove the control box cover. Clear any ice away from BC.
4) Check BC wire harness connections.
5) Disconnect BC wire harness connector from CB CN3 connector.
6) Check for continuity across the wires of BC wire harness connector. When the actuator
paddle is vertical, BC microswitch contact is open. When the actuator paddle is pushed
(tilted) in the moving direction, BC microswitch contact closes.
7) Check that the actuator paddle is not sticking. Clean if necessary. See "II.D.2. Bin
Control Cleaning." If BC microswitch contact still does not open/close, replace BC.
8) Reconnect BC wire harness connector to CB CN3 connector, and plug in the appliance.
Then, move the control switch on the control box to the "ICE" position.
9) The icemaker starts operation after 30 seconds. Press and hold (tilt) the actuator
paddle in the moving direction for 10 seconds. The icemaker should shut down. If it
does not, replace CB.
