Customer Questions and Answers for Infinite Control Switch by Whirlpool

Hello Quentin, This is normally caused by an infinite switch but can be caused by a failing limiter on a surface element. You can find out which elements circuit is causing the issue by removing the wires from all of the "P" terminals on the infinite switches. Make sure they cannot contact anything and power the unit back up. One at a time, touch the wires to the "P" terminals they were removed from. When the circuit causing the issue has the wire reconnected, the light will come on. You will either need to replace that infinite switch or the corresponding surface element. You can check the infinite switch with a resistance meter with the power to the unit OFF by testing from "P" to L1. With the switch in the off position, it should read open. With the switch turned on it should read 0 resistance.

Moose2red, If the element is going off and staying off then you would want to test the infinite switch to see if there is power still going to the element and if the switch is cycling. If it is not then the switch will be faulty and if it is cycling power then the element would be the issue.

Ralph, With just the oven not working on any setting then this will most likely be caused by a faulty thermostat WP9762215. If nothing on the range is working then start at the power supply checking for 240 Vac, then to the terminal block because you are likely dropping voltage.

Justin, The switch for the left front large element would be WP3148953.

Robin, The part number for the 8" infinite switch is WP3148953.

Ralph, NO, the WP3148953 switch is not the dual elements switch. The correct part to order for the model number you supplied is WPW10434452 / WPW10434452 (Per Factory This Is A Dual Element Infinite Switch) . The part is in stock and available at this time. Thanks,

David, The most likely cause for the unit to have a surface light staying on would be one of the infinite switches have failed.

Hello Andrewq, I'm sorry but the manufacturer has not provided us with this information.

Fran, First check or replace the oven temperature sensor WPW10181986. The sensor can loose it's calibration at higher temperatures and after years of usage and produce low and erratic oven temperatures.

Bob, This unit does not incorporate infinite switches but has user interface board part number 316445603KIT. You will want to check the inner burner to make sure that the burner is not bad.
