Hello,

You need a new display kit. The display kit has a new clock relay board and the white harness to the clock. The repair is straight forward.

Hello, welcome to Fixya. To answer your question "Is there a cheaper fix?" In a word...maybe. **Turn off the breaker before attempting any service suggested here please** The first thing to look into is to check the harness which comes from the main relay board to the display head, they can become unsecured from the display or the main relay board/control and that will affect the display in a negative way, i.e. faded or no display illuminated. You may or may not be surprised how much those things vibrate under normal use with the cooling/convection fan running etc. and over time the harness becomes unsecured. Check "J1" on display head as well as "J1" on relay board of the display power harness and insure they are secure in place, wiggle them a bit to see if the display illuminates when turning the power back on. If that doesn`t yield any positive result`s you`ll need a new display head kit part # 492067, it comes w/harness and main relay board ( see image below ) and it is typically about $250 or so, but I haven`t had to purchase one in 4-5 yrs. I`ve checked repairclinic.com and their site says it is discontinued, but if it turns out you need one I may have one in my garage. ( I used to have my own appliance business, hence I still have some "new old stock". we can communicate via email if need be ) Let me know what you find and how it goes with the harness check, I`ll watch for your reply on your post here. I`ll cross my fingers for you it`s just a loose harness. Hopefully this was helpful to move you forward and shed some insight on what to look for at least. Good luck macmarkus :)

local part whare house can sell you a "dim clock" kit for your machine i believe it contains a new display board as well new wire harness

I just found out my baking oven doesn't work and I hear the fan for the convection roast, but no heat. I had the appliance man out and he said that I need a relay board! Big bucks and they don't make this model anymore. Moreover, the microwave and warming drawer work fine. This is ridiculous!

You have to slide the oven partially out of the wall and there is a metal cover panel on top...remove it and you will be able to access the wiring panels, etc.

Have 2 Thermador ovens, SMW272 and SC302. Both have display failure. Just repaired one with replacement display. It did not require a new control unit or harness. Have not opened up second unit yet as display is still dimly/slightly visible.

Called Thermador and received no offer of replacement parts or service. Numerous other web reports of similar failures. My neighbor has 2 dead ovens also unfixed because of outrageous repair estimates ($600 each). Do not recommend this brand.

Full kit including display, control, and harness ordered on Ebay for $170.
