I have a thermador professional rangetop that I just bought used. on installation, the two left burners have no gas and no spark, the other four burners and griddle
all work, tho the flame is uniformly low on all of them. They will boil water or fry an egg, but it takes much too long to do each task due to the low flame
JA: How long has this been going on? And how severe is the problem?
Customer: I have only had it hooked up 2 days. No idea of prior history as i bought it six month ago when starting renovation. To boil 2 inches of water on any of the burners might take twice as long as expected
JA: Do you plan on doing the work yourself?
Customer: Probably. I've already disassembled the burner heads, cleaned the igniter connectors, examined the simmer controller etc.
JA: Anything else we should know to help you best?
Customer: not that I can think of, except the simmer controller has been superceded by a new model. If I have to swap that, I have to swap the potentiometers too. I believe but am not sure that my two non-functioning burners have XLO
