I have a guy who spent $$$ and time waiting for his oven control to be rebuilt back in October. I'm wanting to save him some money. Now he calls and complains that one of his left side burner controls has a spot in it where the gas turns off, but extra low works properly. I've repaired this issue in the past by replacing the potentiometer. Repair Clinic comes up with these two choices:

http://www.repaircli...lNumber=RDDS30V

and

http://www.repaircli...lNumber=RDDS30V

Partdirect comes up with the 497235

Both simmer modules look the same but the pots look different.

Under the product notes on one of my vendors' site, it says the 497234 kit comes with a 422748 pot and the 497235 comes with the 422749 both available on R/C

Does anyone have more experience with Thermador to solve this riddle?

1. Why are they telling me I have to buy a simmer module?

2. Which potentiometer is correct?

Tread carefully, this system has been around for 20-30 years.  As it was explained to me by Thermador (after I let smoke out of a new pot sw) The original vendor who made those is no more.  The new vendor has changed something (conspiracy?) requiring you to replace kit which includes both pot sws and new simmer control.

 

Over the years I have replaced hundreds of the pot sws, but no more unless it's a new unit with current control system.  If your unit calls for the kit that's what you'r going to need or you to will be sending smoke signals to.  The first one I tried just changing the pot sw worked great... for about 10 seconds and then the smoke came out.

There's a service bulletin out that explains the new and old potentiometers and the new simmer controllers that are needed to work with them.  Uploaded to the Pot Luck Supper here ==> http://appliantology...rvice-bulletin/

:thanks: You guys Rock!

I ended up needing the 497235. That bulletin came with the part. I needed it beforehand though because I am not one who likes doing things just cause somebody "say so". :wink:
