Removed the two screws that hold the back glass in place. Rotated old bulb out of it's lamp fixture and replaced it with the new bulb. Replaced glass and reinstalled the screws. The hardest part was finding the bulb ... a very unique 18W flourescent. I wasted a couple of hours trying to locate it locally at my regular suppliers. The order at PatsSelect was easy and direct and the bulb was on my doorstep 3 days later .. an exact fit. Thanks guys.
I live in a small town in South East Colorado. We have just a Walmart and Sears and a few smaller hardware stores. I checked all of them to try to find this 25 1/2 inch Fluorescent Light Bulb, and nobody carried one. I would have had to drive 70 miles to find one. The Service of Partselect was wonderful and the bulb showed up in just 4 days. I was lost without this light. I have bought a few other items for my older appliances in the past from Partselect. com and was very happy with the service and how easy the web page is to navigate. .
Using a flat-head screw driver, I removed the 1 screw from the small "door" on the back, upper right corner. Once the screw was removed, it allowed the door plate to "pop" open; exposing the old bulb. I removed the old bulb; replaced it with the new one. DONE!
