Excalibur 3926TB Food Dehydrator

Update: Excalibur finally responded and said the light bulb wasn't under warranty (which I expected, even though it lasted for only a few seconds). What I wanted to know was how to access the light bulb to change it out. They said I would have to disassemble the dehydrator to access it and by doing that I would void the warranty. What in the world???!!! Overall I like the dehydrator. However, after the 2nd use, the light bulb either burner but or the switch doesn't work. I had only turned it on to inspect the produce, then right back off. I reached out to Excalibur and they needed a list of items from me - just short of my first born child. A 10 second minimum video has to be included. I provided all this information. Wanted to know what bulb and how to access it. SILENCE!!! Now I know this is a small thing, but this is a clear indication of what would happen if the problem were larger and it made my dehydrator useless. Perhaps I will get a Corsi if this one dies. Let me add, that the first one I ordered arrived with the glass falling out of the doors. I returned it to Amazon for a replacement. I know ow someone above in the comments said the racks were plastic. They are NOT plastic, they are metal.
