I am having multiple issues with the oven.:confused:

First it had no top oven broiler output, everything else worked = replaced element

Then lower oven lamps quit, top still worked. Checked out transformer, found to be bad on one side = replaced transformer still no lamps in one oven.

Next top oven quit entirely. Replaced main board and it works again but with very dim display that eventually goes away completely while in use. Now no lamps at all, bulbs check fine.

Any ideas?

I have three Thermador appliances, all have or have had issues.
