looking at an upgrade for the mrs. from our 1940s era 40" wide GE electric. My folks bought it used when they got married. About 5 years back we lost one burner altogether when the control failed and the heat sensing burner is basically an on off now without any heat sensing functionality, that failed ages ago when the capillary gave out, and both ovens now require me to custom rewire the elements as the porcelain plugs have lost their temper and current passing ability.
we're soldiering on, but I just converted the heat to propane and now have the option for a dual fuel and I'm thinking seriously about it.
looking at some older models that I might be able to afford on the used market and the first thing I do is check the pricing and availability for oven controls and burner ignition.
The oven control for this model seems to be of of an analog sort although it might be a digital control concealed by typical knob. Have not found a parts breakdown yet -- continue to wonder where those hide on this site. Thermador coughed up a breakdown for the cooktop parts but not the ovens.
But much discussion on the internet suggests the correct oven control for the larger of the 2 ovens is 486945 which has been discontinued although some repair techs have subbed a 487537 which does allow the oven to work although does not provide operation for the self-cleaning function. Later in those threads there is some suggestiong that the 487537 has been superceded by 622568. To complicate matters the thermador website allows you to put any of these numbers into your cart but when I checked with support they told me the 486945 is discontinued. Not sure they really know what they have and don't have.
Then found a recent thread where someone dispared of help but then found it at Sears online, not clear if he found an old original, or a crossfit with full functionality or a later equivalent.
I wonder given that there doesn't appear to be any digital involved if this is an analog or digital control and how robust it is. Even though it is a twist know I suppose it could have digital elements behind the knob which is always an issue from surges and it is difficult to employ sophisticated surge protection on a 50 amp load. (They ought to make the controls 110 and have a separate plug and then you could put them on the battery back-up side of UPS which has proven the best way to avoid spikes I've been able to find. but I digress.
If they are analog I would I imagine that there is less likelihood of a probelm. While I do see a few people on the net seeking them out, the analog oven controls for my 1949 GE are still working fine. Maybe they forgot how to make stuff that lasts, even on expensive ranges.
Any field experience with these controls and observations on their engineering would be much appreciated.
the smaller oven control is 487259. AGain it shows available at Thermador (but who knows) for much less ($125 compared to $500).
Final problem. The stovetop parts breakdown from Thermador shows electodes or sparkers on each burner but it doesn't show the ignition module or spark generator or whatever it is called. The online parts engine associated with the samauri offers those individual electrodes but no parts diagram I can find and no indication of other ignition parts. (It also, as an aside, doesn't list any oven controls - unsuprising if all available are not really direct replacements).
Any familiar with theory of ops for cooktop ignition and the correct module or style of ignition module? From what I can see this might be a 12 year old range. what is up with this lack of documentation and support? Are you just supposed to buy a new Thermador every 10 years?
