Customer Questions and Answers for Sensor by Whirlpool

Hello Glenn, This fault code indicates a humidity sensor failure. The manufacturer recommends following these steps: 1. Unplug microwave oven or disconnect power. 2. Connect a new humidity sensor to the electronic control (at P5). 3. Replace all parts and panels before operating. 4. Plug in microwave oven or reconnect power. 5. If no failure code appears when starting sensor function, unplug microwave oven or disconnect power. 6. Replace old humidity sensor. 7. Replace all parts and panels before operating. 8. Plug in microwave oven or reconnect power. 9. If failure code appears when starting sensor function, unplug microwave oven or disconnect power. 10. Replace electronic control. 11. Replace all parts and panels before operating. 12. Plug in microwave oven or reconnect power.

Tucker, It would be recommended to check the capacitor on the unit to make sure that it is good but this sounds like it would be a sensor issue.

Hello RFS. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron.

Hello Richard. It sounds like the fan motor is bad and will need to be replaced on the unit. The moisture should not affect the fan in the unit.

Hello Terry, This can be a connection issue between the touch pad WB06X10456 and the control WB27X10655, or simply a stuck key on the display. I'm sorry but this part WB06X10456 has been discontinued by the manufacturer and no satisfactory substitutions have been provided.

Aurora, To replace the sensor you will need to remove the cabinet from installation. Once removed you will need to remove the cabinet of the unit. On the top near the center of the unit is where the sensor will be located.

Hi Art. Is the keypad (no longer available) and the control board part # 8183726 accepting the commands properly? Are there any fault codes? Humidity Sensor: 1. Remove the 3-pin connector from PCBA (P2). NOTE: Do not remove the attached resistor which is used for internal resistance calibration.2. Measure resistance across pins 1 & 3 (ohmmeter scale: Rx1k):- Normal: 2.8k ohms (approx.) at 25°±10°C (77°±18°F) - Abnormal: Infinite3. Measure resistance across pins 2 & 3 (ohmmeter scale: Rx1k):- Normal: 2.8k ohms (approx.) at 25°±10°C (77°±18°F) - Abnormal: Infinite. Sensor part # 8206446. Thank You.

Hello Marlon. Based on the information you provided, it sounds like the door switches W10211974 are bad and will need to be replaced. You will need to test and see which ones are bad. NC to COM should read closed and NO to COM should read open. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
