Our Thermador RDF30QW range (Ser# 95120118) has three problems, and I'd like advice on what's easily repairable (and new part numbers if known). First, the right front burner no longer lights from its own control, but will light if I turn on a second burner at the same time. Second, the convection fan no longer runs on "Convect" mode - it's been starting up slowly until recently, but now not at all. Finally, like other posts, the digital display can't be seen anymore - it's been a problem for several years. Is part number AP2836528 the correct replacement? Is it still available?

Appreciate any help you can offer...

Does the red light to the left turn on when trying to light the r/f burner?

Yes = Spark Module
No = Spark Switch

Second, the convection fan no longer runs on "Convect" mode - it's been starting up slowly until recently, but now not at all.

This is, most likely, a bad fan. The only other thing I can think of is a bad wire connection at the fan or a bad connection on the ERC (Clock).

Finally, like other posts, the digital display can't be seen anymore - it's been a problem for several years. Is part number AP2836528 the correct replacement? Is it still available?

If there's a good 120vac at the ERC, it's bad. The part is no longer available, however, it can be rebuilt by CoreCentric Solutions. Their number is 866-737-2244. The Thermador number for the ERC is 486752, which is what CCS knows it as.


Good Luck,

Thanks for the info - it's quite helpful. But I did have a followup question. In your response to the problem with the r/f burner, you asked if the red light to the left came on - I'm lost. I can't find, and don't remember ever seeing, a red light indicating burner function. There's no such indicator on the ERC (even if it was visible), and I'm not sure where to look. If this is a braindead question, my apologies.

Sorry, I was thinking of an RDFS unit, which has the exlo feature. These units have red lights to remind customers that the burners are on.

On your unit, another way to check is by noticing if the other burners are sparking while the R/F is trying to spark.

If yes = spark module
If no = spark switch

You may also want to make sure the burner base is clean and in good shape. I've seen situations where a bad, dirty or poorly grounded base will prevent the spark from jumping across from the igniter.

Thanks, KC - I thought I was going mad (looking for the red light...) From your last post, I'm pretty sure it's the spark switch. As noted, the r/f igniter works perfectly if I turn on any other burner at the same time. The r/f by itself does not spark. If it is the switch, I'm having trouble finding a replacement in the APP.com website. I've entered Thermador, model RDF30QW, and then chosen the earlier serial number option. The schematic for gas manifold seems to be the one I'm looking for but it doesn't list "switch", only "valve" (and of course the r/f (orange) valve is "not available".) "Valve" doesn't seem right - am I looking at the wrong schematic?

what are the part numbers for the above spark module and spark switch?
for a RDSS30QB thermador range.
