Can not find part number for heating element replacement. Ser # MU3915952.
Answer Diane, I believe your model should read WGD6400SW1. This is a gas dryer and does not use a heating element. Please contact us at your earliest convenience for further troubleshooting assistance. Thanks.
How do you test a heater coil?
Answer Hello Rufus. The heater 279837 should read closed for continuity. 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
