Keith for Model Number GR470LXMC ceramic range whirlpool I cannot turn on the dual burner and think the infinite switch is bad. Before I order the switch, I would like to confirm. Can you give me the pinouts along with a way to check the switch?
Answer 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). Read More... Answered by AppliancePartsPros.com | Wednesday, February 5, 2014
