Product review (5 stars): Easy fix for my TERRIBLE VIKING RANGE!
Easy to change on your own.  I saw that mine was cracked, looked on here for a new one and ordered it.  When it came in, we shut off the power, unscrewed the screw on the plate, gently pulled them out of the two little sockets that they ends slide into and replaced with the new one.  That would have cost plenty from a repairman.  First a visit to see what's wrong.  Then, they'd order the part, upcharging me, of course.  Then they'd return to replace it.  Big bucks.  We saved a ton doing it ourselves.

On another note, I'd NEVER buy a Viking range again.  We have had nothing but trouble with it from day one and that thing was big bucks. We paid 5 grand for it, thinking we'd have it forever and it's been trouble from the get-go. The Viking repair person even had to come out when it was first installed to fix a busted knob.  The burners have broken a couple of times and the oven has stopped working twice.  I'm telling you, don't purchase a Viking range if you're thinking of that.
