Contactor Replacement
(KR1203 and KR1403 Grinders)

The newer 1203 and 1403 coffee grinders have a contactor on the base of the grinder that might need replacement after some time. 

1.     UNPLUG THE GRINDER.

2.     Place the grinder on its back on the table. Make sure the grinder is forward enough so that the cable is not crimped and can hang freely.

3.     Remove the 4 corner screws holding the base onto the grinder. Be sure to have a firm hold on the base so that it does not fall away from the machine.

4.     Gently pull the base away from the housing, making sure not to pull out any of the wires from the base terminals.

5.     Remove the 2 screws that are holding the contactor on the base.

6.     Using the same screws, place the new contactor in its place.

7.     Transfer one wire at a time from the old contactor to the new one, making sure that the wire goes to the same position on the new contactor.

8.     When all the wires are transferred, check and tighten all the screws.

9.     Check and make sure that no wires have pulled out from the terminal block on the base.

10.  Position the base on the housing and replace and tighten all 4 screws. Make sure that no wires are pinched between the base plate and the housing.

11.  Place the grinder upright on the table. Plug the power cord into the outlet and test the grinder.
