Questions & Answers

For Whirlpool Door Switch (Refrigerator Light) (Part Number: OEM18027972)

1 Answer

Sharon, The most common issue for your complaint description is, something has overflowed the bin and wrapped around the power screw and jammed the motor. That leaves the ram in a partially engaged position and you can't open the door. There are several "hidden" switches that could be the cause, as well, but you will need to remove the compactor and remove the top panel to access most of them. We'll be sending you some information that should be helpful.

Hello Don. This is the only door switch listed for your model. While it is a little different than the original, it should be a functional equivalent. It is likely one of the three terminals would simply just not be used. If you order this part and have any trouble with the installation, you can visit the repair forum we have on our website and the techs there would be able to walk you through most any issue. I will include a link in this message to the forum. I hope this info helps. http://forum.appliancepartspros.com
