e.Tumbler (Basket) Junction Box Disconnect

Remove the four (4) bolts that hold on the lower left side panel, then remove the panel. Next, remove the safety panel by removing the six (6) bolts on the bottom of the panel where the tumbler (basket) section and the base meet. Reach into the feed through hole in the base of the tumbler (basket) section, where there will be two (2) cables there. Pull both cables through the hole into the tumbler (basket) section. The cable with the connector on the end is for the tumbler (basket) junction box, the other cable is for the left drum motor. Leave that cable in the tumbler (basket) section (it will be covered in Section f below [Left Drum Motor]). Check keying between the plug and tumbler (basket) junction box. Insert plug into connector on the junction box and engage locking clasps. Leave the lower left side panel and the safety panel off the machine until left drum motor is reconnected (refer to Section f below [Left Drum Motor]).

f.Left Drum Motor

There are two (2) different ways that the left drum motor is connected with or without the motor disconnected junction box. The junction box is used when the connections to the left motor are made on the back side of the motor, nearest to the tumbler (basket). When connecting the motor, bring the left drum motor cable (refer to Section e above [Tumbler [Basket] Junction Box Disconnect]) and mechanically connect it to the junction box on the motor or the external junction box with the lock nut. There will be four (4) wires in the cable, match them with the PVC electrical tape. There should be one

(1) green wire remaining, which is used for the ground connection. Replace the screws that go on the cover of the junction box. Bolt the safety panel back in place using the six (6) bolts removed in Section e above (Tumbler [Basket] Junction Box Disconnect), then bolt the lower left side panel back in to place using the four (4) bolts also removed in Section e above (Tumbler [Basket] Junction Box Disconnect).
