Question and Answers

Q:

How to switch dryer door hinge on a Whirlpool Duet Model # WED9400SW1? Door was reversed upon installation, would like it reverted back to "normal".

A:

I added the door swing reversal instructions in the image I added below. It should not take but 30 minutes and all you need is a Philips screwdriver and small flat blade screwdriver. NO additional parts are needed.

Q:

My Whirlpool Duet Dryer model WED9400SW1 stops after several minutes and displays error code F22. Does anyone know how to repair this?

A:

Thank you for your question and I understand your concern.

The "F22" fault code flashes if the outlet thermistor is open or if it has an open outlet thermistor circuit between the thermistor and control board. If the outlet thermistor tests Okay and the wiring connecting the outlet thermistor to the control board is Okay; then the electronic control is faulty. You will need to disconnect the power cord from the power source and then remove the lower access panel. You will need an Ohm meter to test resistance of the outlet thermistor. I added an image below with the instructions and the resistance specification of the outlet thermistor. The part number of the outlet thermistor is #8577274. If you find it faulty; it can be ordered at SearsPartsDirect .

I added a YouTube video showing how to access and replace the outlet thermistor.

Check the things I have covered here and if I may be of further assistance as more details become available, please reply to this post.

Ronny: I would use an Ohm meter and check the thermistor for resistance and then check both wire leads from end to end for continuity with the Ohm meter.

Ronny: The "F22" indicates a open outlet thermistor or open thermistor circuit. I assume you installed part #W10256719 for the control board and part # 8577274 for the thermistor. I would leave the thermistor connected and then disconnected the P14 connector from the control board and measure the resistance across the two red wires. At room temperature of 80 degrees the thermistor should measure approximately 8.5-10.5 Ohms.

Ronnie: Yes, leave the thermistor connected and then go up to the control board located under the top on the side panel and disconnect the harness with the two red wires (thermistor connection). Measure the resistance across the two red wires and it should measure the same as if you were measuring directly across the thermistor. I added the wiring diagram below and I circled the connection that will need to be disconnected before measuring across the two red wires. Be sure to disconnect the power cord from the power source before taking the top off and disconnecting the connector.
