PF alarm appeared on display. Noticed clicking when cord was moved. Had arced for some time and melted original block. New part slightly different. Only has 3 lugs, old one had six. Stack using washers provided. Take note of colors before disassembly. Use caution while working through access opening. The edges are sharp. Only tools needed are phillips screwdriver, deep socket for lug nuts. Nut driver optional. Hope this is helpful.
Most of the job is simple fastener mechanics. Use a nut driver or Phillips screwdriver. Remove rear panel.
Pull out control knob. If it is stuck, wrap a small rag around the back of it and pull the rag steadily.
Carefully match marked terminals on the replacement switch with those on original. Switch terminals may not be in the same location. Replace wires one for one, one at a time.
Carefully select the correct knob filler for the switch post. Several are supplied. Proceed with logic and measure the shaft length and the filler length and type to match.
First of all I removed the top panel then removed the switch. I then took pictures of the switch & drew a sketch with all the info. Then I went to your web site, matched up the switch & ordered. When the switch arrived I went thru the above replacing the bad switch.
