My technician changed two infinite switches on a radiant cooktop.

The part that was changed is 700855K. Issue is that the two right side burners, after connection, control each other’s heat level. Burners turn on independently and the issue with heat control is only applicable if both burners are operating simultaneously.

Could you provide guidance on proper wiring instructions for these switches? My thought is that the technician did the wiring incorrectly. The old switch for reference is part# 203147. The confusion lies in a difference for terminal markings between the old switch (203147) and new switch (700855K).

I’m the owner, but not a technician. Please let me know if there is a bulletin or supporting document for the issue.

Thank you,
Greg Bahry

What have you tried so far?

Original complaint was the burners stopped working. That has been resolved by replacing the infinite switches.

I have provided the service manual with your wiring diagram in section 5-57. I also provided a parts breakdown to be sure you have the correct parts.

  • Based on the parts diagram, I see two parts numbers represented for the infinite switch, 703247 and 700855. We had used 700855 for both right side burners. From what I see, we should change one to 703247, is that correct?
  • I see the issue now. This is a series 6, which calls for 703247 for all 6 switches.
  • I’m glad the diagram helped.
