Davev for Model Number WMH53520ASO When attempting to heat my microwave is making a clicking noise behind the control panel for about 2 seconds and shuts off. I've heard this is usually a problem with the door switches but may be a controller board. Please indicate your thoughts on this? Are the two pronged door switches at the top & bottom interchangeable? What does the additional 3 pronged switch on my top position handle functionally? Thanks, Dave
Answer Davev, The 3 switches would be the primary at the top and the secondary at the bottom which will be the same. The middle switch will be the monitor switch. The switches would not cause a clicking noise. This issue would most likely be a faulty control board. Read More... Answered by AppliancePartsPros.com | Friday, May 12, 2017
