Maria I ordered this part for my microwave model #KHHC2090SSS and switched out both bulbs above the stove top and still not working. Although, the cooktop fans still work and everything else, s.a. the display, etc. If the relay board needed to be replaced, would these other things still work? While installing the bulbs, possible to have touch them, but also possible could be a bad pair of bulbs or damaged. Trying to figure out if it's the bulbs, or the board. Your help is appreciated.
Answer Hello Maria. Test for power coming to the lamps. If there is none there, then the relay board 8206603 will need to be replaced for the lights to work on 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 Read More...
