Customer Questions and Answers for Range Surface Element Switch by Whirlpool

Hello Paul, This is a contact in one of your infinite switches that is stuck. The easiest way to determine the failed switch is to turn the power off to the unit and remove the rear cover from the control panel. This exposes the infinite switch connections. Now, as long as you're sure the power is off, remove the four violet wires from the "P" terminals on each of the infinite switches. Make sure none of the wires can contact anything so you don't short anything and cause more issues. Re-connect the power to the unit. Now, one at a time, touch the violet wire to the "P" terminal on its' respective infinite switch. When the light comes back on, the switch that caused it is the bad switch. This is the easy way to test for the bad switch. You can also test for the issue with an ohm meter. This procedure is done with the power off during the test. You have to test from the "P" terminal to the "L1" terminal on each infinite switch. The test should read open, (no continuity). When you get a reading on one, it is bad. Be sure to test them all in case more than one switch has issues. This goes for both testing procedures.
