KBCC-125R Motor Control 115V (3/4 or 1 HP)
There are two tests that can be performed separately to test the motor control: Main Speed Pot Test and Direction Switch Test. But first, check to ensure that all the fuses on both the machine and the motor control are good before proceeding. These two tests can also be used determine if the main speed pot and/or the direction switch is at fault. For either test, the customer will need to create a short jumper wire approximately 6 inches long to use to jumper two terminals together. Be sure to power off the machine and unplug from power source. When running these tests, remove all label materials and rolls from the machine. You should also check to make sure that the ice cube relays (K1, K2 and K3) are secure in their sockets and operating properly.
Main Speed Pot Test
- Power off machine and unplug from power source.
- Unhook wires P1, P2, P3. (Important: Make sure the wires you are removing do not touch ground or each other).
- Place jumper wire between P2 and P3.
- Plug machine back into power source, and turn power switch on.
- USE CAUTION (Because the machine could run at full speed): Press start button and the machine should run at full speed. (NOTE: Main speed pot will not function during this test) If the machine does not run full speed, then it is a bad motor control, replace motor control. Side Note: If the machine did run at full speed, this could mean that the main speed pot is bad, replace main speed pot.
- Power down the machine and unplug from power source. Remove jumper wire & re-attach wire 67 to P1; wire 73 to P2; wire 69 to P3.
Direction Switch Test
- Power off machine and unplug from power source.
- Unhook wires S1, S2, S3 located at bottom right of motor control. (Important: Make sure the wires you are removing do not touch ground or each other).
- Place jumper wire between S1 and S2.
- Plug machine back into power source, and USE CAUTION because the machine should start as soon as you turn power switch on. If the machine did not start as soon as you turned the power switch on, then it could be a bad motor control but make sure to check the K1 relay to see if it is working properly, if it is then replace motor control. Side Note: If the machine did run as soon as you turned the power switch on, this could also mean that the direction switch is bad, replace direction switch.
- To test for the opposite direction. Power down the machine and unplug from power source. Remove jumper wire from S1 and hook it to S3 (this will cause the machine run in the opposite direction).
- Plug machine back into power source, and USE CAUTION because the machine should start in the opposite direction as soon as you turn power switch on.
- Power down the machine and unplug from power source. Remove jumper wire & re-attach wire 78 to S1; wire 75 to S2; wire 77 to S3.
