My more than 10-year old Thermador RDFS30QW Gas Stove recently had some problems with the burners/igniters. I have 2 xtra low buners on the left and 2 regular ones on right. The LR xtra low would not ignite at all and no gas out after I turned on the knob. The other three buners have diffult times to ignite. Some times, I am lucky to get it ignited, but most times I have to use my portable ignitor to ignite it. Some times, when I turned on the knob, the ignitor clicked once but failed to ignite. Some times, it didn’t click at all. Anybody has any idea?
I tried to take off the cook top, but couldn’t find how to do so. Do I have to take off the burner first? Anybody can share with me the service manual? Thanks a lot!
