Selector Valve Motor/Encoder Replacement

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Procedure

1. Remove power to fryer and move to allow access to left side panel.

2. Remove left side panel and filter pan.

   

3. Remove 2 screws holding in control assembly of fryer and rotate down.

4. Unclip harness for selector valve encoder and remove any wire ties holding this harness.

5. Pull through electrical enclosure.

   

6. Remove 2 screws holding in harness, remove grommet from cable and keep parts for later assembly.

7. Unclip harnesses for selector valve motor and filter pan switch, set aside.

8. Remove 3X button cap screw from the valve body and encoder and set aside.

9. Remove old motor / encoder assembly from fryer and discard.

10. Remove coupler and set aside.

    

11. Align spool so that the spool alignment indicator points towards the home port and the home port is full open, if not already.

    

12. Place coupler back onto spool ensuring the male tang of the coupler engages the spool and is centered.

13. Use some grease on the male tang.

14. Place new motor / encoder assembly on to the spool valve ensuring the motor tang engages the female tang of the coupler.

15. Fully seat the assembly to the spool and align screw holes. May need to exert force to get the screw holes to align by compressing O-ring on spool valve.

16. Apply blue Loctite to the cap screws and reinstall, torque to 34 in-lbs.

17. Clip the new motor wire harness, filter pan switch and new encoder cable back to their original locations and secure.

18. Motor wire pair should be twisted approximately 2 twists per inch.

19. Re-install the rear bracket of the selector valve to the frame.

20. Test selector valve operation using tech mode or in filter mode.

21. Upon successful results, return fryer to service.
