Customer Questions and Answers for Start Switch by Whirlpool

Hello Audra, First put the ohm meter on the lowest setting where a horseshoe symbol appears. Touch the leads together to see what no resistance looks like and to ensure the meter is working properly. Now, with power disconnected from the unit, place one meter lead on one terminal and the other meter lead on the other terminal. It should read open at this point, just like not touching anything with the meter leads. The3 meter should read like touching the leads directly together when the button is depressed.

Hello Bo, This sounds like an issue with the centriugal switch i the motor assembly 279827.

Hello Mary. The motor is bad and will need to be replaced on the unit. The switch on the motor is bad.

Hello Keith. It could be a bad start switch. However, if the motor hummed before it started, you may have an issue with a bad motor and it finally went out in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Rich, You will want to check the door switch to make sure that it is not broken and make sure that it has continuity when closed. If this checks ok then test the thermal fuse on the blower housing for continuity. If there is no continuity then it will need to be replaced and check the venting from the blower wheel to the outside of the home to make sure that there is continuity.
