1. Turned off the 240V branch circuit to the cooktop.
2. Removed and inverted the cooktop.
3. Removed the bottom panel, used 1/4-inch nut driver to remove the sheet metal screws.
4. Confirmed the circuit was de-energized. Voltmeter set to AC, measure across the L1, L2 connections, should be 0 VAC or very close.
5. Make a diagram of the existing connections to the controls to be replaced, note all control markings (L1, L2, H1, H2, PL) as the replacement controls have connectors in different locations.
6. Remove the AC Mains plate, 2 sheet metal screws.
7. Make a diagram of the primary AC distribution blocks.
8. Remove the AC Mains input leads, Red and Black.
9. Remove the AC distribution to the controls from the primary AC distribution blocks. Needed to free up the control panel.
10. Remove the 4 sheet metal screws holding the control panel.
11. Rotate the control panel to access the screws holding the controls. Caution on the wires to the heating elements, watch for pinching.
12. Remove one control with the wires attached.
13. Install the replacement control. Secure the screws.
14. Transfer the wires, matching the connection marking (L1, L2, H1, H2, PL) exactly.
15. Do the same (12, 13, 14) with the next control.
16. Re-install the control panel. Check all wires for clearance.
17. Re-connect the control wiring to the AC primary distribution blocks.
18. Re-connect the AC mains wiring to the primary AC distribution blocks.
19. Re-install the AC mains plate.
20. Visually check all the connections. Shake out any debris.
21. Replace the bottom cover, installing all screws.
22. Remove the gasket strip from the mounting lip, clean the surface, install new gasket (weather stripping).
23. Re-mount the cook top.
24. Energize the 240VAC branch circuit.
25. Test the controls. Correct any errors.
26. Done! Go have some hot tea! (or a beer)
