Here's one for ya,

Thermador range, model described above about 10 - 11 years old.  2 burners are xtra low, 2 are standard.  LF xtra low would not ignite, followed Thermador service book, traced it to igniter brain after checking all the book said and then some.  Got a new one, put it in and voila, burner works fine, lights everytime.  Great, right?  Well if you use 1 of either the LR or RF the igniter clicks continuously, just like it did after I troubleshot it orginally.  The key here is it did not do this until I troubleshot the darn thing.  Reading all I could here, suggests a ground issue or dirty igniters.  Everything looks good (at least to me), but the clicking continues if using one of the mentioned burners.  Otherwise new brain has solved all ignition issues.  Could the new brain be faulty, probably not is my thought.  Need ideas.  Naturally no service that's anygood for this unit.

Thanks for any help,

Mike

The LR and RF burner do light after clicking; however, if I only light the RF burner, the clicking continues also vice versa, if I light the LR burner only, the clicking continues.  The igniter brain clicks all 4 burners at once.

Thanks again,

Mike

Does the clicking stop once the burner is lit ?


 

I'm searching for the Thermador service manual....

If the LR and RF burners are lit together clicking stops, do not have the issue with the other 2 burners.  That's why I'm thinking it's something stupid.  If I use the LR or the RF burner without the other lit, the sparking/clicking keeps on clicking.

Thanks for your help,

Mike

I looked at the service manual.

Do you have the (2) grounding screws (tight) and the one connector screw installed ?

Are you sure you don't have the ignitor wires crossed for those two burners?

If this is possible, I'm sure it would cause the problem your having, since all click at the same time when any burner is turned on it lights ok, but doesn't sense a flame because the ignitor that is looking for flame is on the burner that isn't lite, (unless of course you light both burners).

I have the 2 ground screws tight as I specifically checked them.  Not sure what you mean by the connector screw, any hints will be appreciated.  I have the service manual, but haven't found the connector screw. 

Have I crossed the 2 wires, hmmm???, anything is possible, I can switch and see what happens.  I thought that the wires basically only reached to their respective burners, but I will check as I have nothing to lose, everything to gain.

Thanks for you help,

Mike

Willie,

You got it!  I had the 2 wires crossed, even though I had checked that earlier on the schematic.  Not sure why I didn't see it.  Anyhow, the old Thermador now works like a charm.  No more bleeping clicking. 

This Thermador's a nice unit, best oven I've ever used, and the xtra low burners are nice; however, as we all know here, it's no more reliable than any other brand.  Overall, mine hasn't been bad and thankfully I got a Thermador guy out at their place in Calif to send me a service manual some years back.

I owe you a big beer.

Mike
