5. Insert the meat probe into the far-left socket port #1 on the unit and the other end into ice water. (FIG. 7)
6. On the screen, verify P1 meat probe reading.
   • A. It should be between 34-38 degrees for a correct reading.
   • B. Any temperature above or below that range, contact factory 800-222-4393 option 3.
7. Repeat steps 5 and 6 for the 3 remaining probe sockets.
8. Once faulty probe sockets have been identified and confirmed, turn the unit off.

15. Follow the wires back to the control board, taking close notes of where and how they are connected. (FIG 5)
16. Remove wires from the control board. (FIG 6)
17. Locate the new probe socket and wire to the control board the same way the previous one was.
18. Mount probe socket to unit using screws removed in step 12.
19. Silicone around the probe socket to ensure it is fully sealed so no cavity vapors can get into the control area.
20. Repeat steps 11-19 for any other faulty probe sockets identified in step 6.
21. Once all faulty probe sockets have been replaced, plug the unit back in.
22. Repeat steps 1-7 and confirm all probe sockets now read within the correct range.
