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 ... Read more 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.
