Steps:

  1. Turn each surface knob to verify whether only one burner or all burners fail to heat.
  2. If all elements stay cold, suspect a supply issue rather than an individual component.
  3. Wear rubber lined gloves before handling live power circuits.
  4. Partially unplug the range cord, place meter probes on each flat prong and the neutral to verify 120 V per leg and 240 V across both hots.
  5. If probe contact is poor, unplug the cord fully and measure inside the receptacle instead.
  6. Reset the range breaker fully off and on if either 120 V leg is missing.
  7. Contact a licensed electrician if proper voltage cannot be restored at the receptacle.
  8. Slide the stove out and locate the terminal block where the cord enters the chassis.
  9. Look for scorched insulation, loose lugs, or melted plastic on the block and incoming wires.
  10. Replace the terminal block if any damage is present before continuing tests.
  11. Measure 120 V from each hot to neutral and 240 V across both hots at the block to confirm supply integrity.
  12. Unplug the range and remove the quarter-inch hex screws securing the rear cover to expose the infinite switches.
  13. Keep the screws in a safe container so reassembly is easier.
  14. Match each control knob to its corresponding switch cluster on the back of the panel.
  15. Robert Shaw single-burner switches use terminals marked L1 L2 H1 H2 P1 while Ego multi-zone switches use number pairs such as 2-2A and 4-4A.
  16. Photograph every wire orientation before disturbing the connections.
  17. Grip each spade connector with needle-nose pliers and pull them from L1 L2 H1 H2 P1.
  18. Attach meter leads to L1 and H1 or to L2 and H2 and set the meter to continuity or resistance.
  19. Rotate the burner knob; a closed circuit should appear on any active heat setting.
  20. A persistent open reading identifies the infinite switch as defective.
  21. Leave the outgoing element wires disconnected and place meter leads on H1 and H2.
  22. A resistance between 10 Ω and 70 Ω confirms that the element circuit is intact.
  23. An OL or very high resistance reading indicates an open element or broken wiring.
  24. Remove wires from an Ego dual or triple switch and locate matched pairs such as 2-2A and 4-4A using the printed schematic.
  25. Clip the meter to a matched pair and turn the knob to the corresponding ring size; continuity should appear for each active coil.
  26. No continuity on any coil pair points to a failed switch.
  27. Connect the meter to the matched outgoing wires for each coil and measure resistance.
  28. Values outside 10–80 Ω or an open loop indicate a damaged burner element.
  29. Physically trace the colored wires to ensure you are probing the correct pair.
  30. Pull the control knob forward to remove it from the shaft.
  31. Undo the two Phillips screws and withdraw the faulty switch from the panel.
  32. Transfer each wire to the identical-labeled terminal on the replacement switch.
  33. Reinstall the switch, tighten the screws, and press the knob back onto the shaft.
  34. Remove the three Phillips screws along the top lip of the oven cavity and slide the cooktop forward.
  35. Pivot the glass upward and support it with two sturdy 1×4 or 2×4 boards.
  36. Handle the glass carefully; it is heavy and can break if dropped.
  37. Remove the single hex screw on each side of the metal cross-bracket that supports the elements.
  38. Lower the bracket with the burners onto the range chassis so the wiring is accessible.
  39. Inspect each heating coil for cracks, scorching, or displaced ribbon.
  40. Check every spade terminal for heat damage or corrosion.
  41. Spot-test continuity from each male spade to the nichrome ribbon; an open reading confirms failure.
  42. Depress the spring clips with needle-nose pliers and lift the element free of the bracket.
  43. Photograph clip positions and size markings for reassembly accuracy.
  44. Position the old clip set on the new element in the identical labeled holes and tighten the screws snugly.
  45. Flip the element over and push each clip until it snaps fully into the support bracket.
  46. Match each wire to the identical letter or number on the new element using the photo for reference.
  47. If a lead is too short, crimp the supplied splice and cover it with the insulation sleeve to prevent shorts.
  48. Plug the range in and momentarily energize the new burner to confirm both ring sizes glow evenly.
  49. Disconnect power and allow the element to cool completely before final assembly.
  50. Lift the burner assembly back into position and align bracket holes with chassis holes.
  51. Install the hex screws, then lower the glass top and engage the rear locating tabs.
  52. Reinstall the three oven-lip screws to lock the top in place.
  53. Slide the range back to its original position and verify all burners cycle on and off correctly.
  54. Adjust any bracket alignment if an element sits off-center beneath the glass.
