Thermador pc48 burner wont ignite

Burners Do Not Start Hand on burners The Burners Do Not Start There are several solutions for this problem: The main gas supply may not be turned on. Make sure it is turned on. Check the power supply and make sure the unit is plugged in and the circuit breaker has not tripped. Make sure the burners are properly positioned. The igniters may be dirty. Carefully wipe the igniters with a cotton swab dampened with water after they have cooled down. Gently scrape the soil off with a toothpick. Avoid exposing the igniters to excessive water as a damp igniter may not light up. Remove any lint that may remain after cleaning. The ignition will be quicker if a cooking pan is on the grate. Ignite the gas at full and once alight, turn it down to around 50%. It should lock on within 6 seconds. Does the burner click when the burner knob is in the ON position? If yes, you may have a wiring issue at the outlet that the appliance is connected to. Turn off the main gas supply and contact a qualified electrician to fix this. Does the burner click when the burner knob is in the OFF position? If yes, check for the following: 1. Check to see if the burner cap is properly placed and the igniter is not wet or dirty. 2. Check to see if the regulator supplied with the unit is installed properly. The arrow on the regulator should be pointing to the appliance. Please call a professional installer

try cleaning the burner completely and make sure it is dry when done

Most gas range tops no longer have pilot lights but use an electronic ignition (sparker) to light the burner. Normally when you turn the burner on you should here a snapping or sparking sound, at which point the burner should ignite. Here is a link to the user manual for 36" - 5 burner Thermador rangetop...maybe this will help: http://dl.owneriq.net/a/ac64ae7b-1ed3-44a3-9235-e4dbd8fe4628.pdf

By the way, in the short term you could always use a match to light the burner. JUST BE VERY CAREFUL THE YOU HAVE THE MATCH LIT AND OVER THE DESIRED BURNER BEFORE YOU TURN KNOB TO START THE BURNER!!!!

I would say that pop was one of you igniters.  either that or the stove is not installed correctly and when it gets warm, thermal expansion makes the metal pop.  I would say that I would use caution and discontinue its use.  Most problems with these need to fixed professionally.

sounds like you have a bad switch. maybe on the large burner.. some of those switches can be replaced without the whole harness.

if its one of the center burners witch has the auto on off for extra low its the moduel under the handle
Potentiometer

Either the potentiors or the simmer control.
