  • Disconnect power at the breaker before servicing
  • Access the switch from the control panel/backguard per your model
  • Move wires from the old switch to the new one, one at a time, matching terminal positions/labels

Hello Gary, The most likely cause of this would be the infinite switch. If it is for the left rear element, you will need WP9761048.

Hello Keith, To test the infinite switch for a dual burner, follow these instructions: 1. Disconnect the electrical power to the range. 2. Set the ohmmeter to the R X 1 scale. 3. Turn the dual element infinite switch to the “single” position. 4. Touch the ohmmeter test leads to the following terminals. The meter should indicate continuity (0 O): a) P1 - 4. b) P1 - S2. c) P2 - 2. 5. Touch the ohmmeter test leads to terminals P1 and 4a. The meter should indicate an open circuit (infinite). 6. Turn the dual element infinite switch to the “dual” position. 7. Touch the ohmmeter test leads to the following terminals. The meter should indicate continuity (0 O): a) P1 - 4. b) P1 - 4a. c) P1 - S2. d) P2 - 2. To test the left front (LF) dual element and limiter: a) Disconnect the wires from the dual element terminals. b) Disconnect the wires from limiter terminals 1A and 1B. c) Touch the ohmmeter test leads to the 800W element terminals (orange/white wire). The meter should indicate 50 O ±10%. d) Touch the ohmmeter test leads to the 1600W element terminals (orange/black wire). The meter should indicate 38 O ±10%. e) Touch the ohmmeter test leads to limiter terminals 1A & 2A. The meter should indicate continuity (0 O). f) Touch the ohmmeter test leads to limiter terminals 1B & 2B. With the temperature below 150°F, the meter should indicate an open circuit (infinite). With the temperature above 150°F, the meter should indicate continuity (0 O).

Anne for Model Number IRE82300 Inglis

Hi, I have an Inglis smooth top range & the DUAL heating element is staying on high, I took a picture of the switch for this element and it is solid blue with the following written on it 9761048, P1 top right, P2 S2, bottom right. The reason I question if this is the right part for my stove is because in the video your switch is white with a piece of visible metal that looks just like the other 3 remaining burner switches on my stove. My dual burner temp control switch is a solid blue box with no visible metal. Do you sell a temp control switch that will work for my stove. Thank You MODEL # IRE82300 INGLIS
