The Miele KM326G cook top has 5 burners: 2 small simmer burners, 2 normal sized burners, and 1 large Wok burner. The 2 simmer burners still work good as new. The 2 mid sized burners do not work at all - no gas flows to them. The large Wok burner does have some gas flow, but on the highest setting is produces a flame like it used to on the lowest setting. All 3 of these problem burners were working two weeks ago. Cooked dinner one night, the next night, no gas, no flame. No cleaning of any kind was done in between. Thanks!

The electrical portion of the switch is bad, you need to replace it.

LPG to natural, natural is bigger than LPG injector exmaple LPG 50=natural 69-
LPG 78=natural 91
LPG 85=natural 115
LPG95=natural 130
PLG 62=natural 85

Hello Leighvz,
The rings around the burners should be cleaned periodically. Each one has a series of holes to let the gas come out and have to be set back perfectly or else you will continually have this problem. You can clean with regular dish soap an water and a sponge or rag.
Also, If you put a pot or pan on the burner and it is too large it will cut off oxygen to the burner causing your clicking. The clicking only occurs when the oxygen supply is not enough. Hope this helps

Hi JHMcdona

Most likely the electrode for the right burner is defective. As well as the switch may also be defective (is shorted because of pressing hard on it trying to make it work!!). Change the electrode and igniter switch of the right front burner.

Regards

I had a similar problem and discovered that the control knob had fried itself, most likely due to liquid penetration down the shaft of the control knob and into the control knob electronics. Inside is a printed circuit board with resistor, diode and a rheostat. The surface of the board was charred beyond repair.
To trouble shoot the problem, open the cook top and hook the burner in question to one of the known good control knobs. If it ignites, then it is the control knob electronics. If it doesn’t, then there is something wrong with the igniter.
Note: The 2-zone Wok Burner had a different control knob that the other burners.
To open the cook top, do NOT loosen any of the Phillips screws on the sides. Here are the instructions from the user manual:
Disassembly
Shut off gas supply, disconnect the manifold pipe, disconnect the electrical power. Remove pan supports, burner heads and burner rings. Remove control knobs.
In the event that the hob is built in, undo the bracket clamps underneath the work surface. Lift the hob on to the work surface. Unscrew the venturis on the high-speed and super high-speed burners using a 20 mm wrench. Lift and remove the burner rings and burner base plates. Disconnect the wires from the ignition plugs. Keep the wire from dropping into the undertray by inserting it in one of the slots in the burner supports.
Remove the three screws securing the dual ring wok burner. Remove the wok burner base plate. Lift the ceramic tray from the hob.
Note: Each regulator shaft is equipped with a black ring. This ring may cling to the rubber seal in the ceramic tray. Check and remove the rings from the rubber seals.

Lowly what the potentior does is turn on the burner control system. When you turn on a normal burner you are opening a gas valve and closing a switch to generate a spark. Thus gas flow to the burner and spark. On the extra low simmer burner there is a electric solenoid between the burner head and the gas valve. this has to open as well for gas to flow. What the potentior does is signal the simmer control what level of flame you are requesting and telling the spark module to generate a spark. Once you go to the exlow setting the potentior tells the simmer control what level of heat and will cycle the flame on and off. So when the burner knob was between low and extra low, the flame would cycle on and off. You have to seperate the top section of the cooktop from the burner box to change the potentior for it sits on top of the gas valve for that burner.

lowly is it the left burners that won't lite? I only ask as depending on the model some of the Thermador cook tops had simmer control burners. This is a 3 part system on the burners. 1 a simmer control, 2 electric solenoid, 3 potentiors. When you turn on the burner the potentior tells the simmer control to send power to the gas solenoid. At the same time the unit will spark. If your unit has extra low on the left 2 burners then you have this system. The usual problem in the potentior. Hope this helps.

Either the potentiors or the simmer control.

Most likely you got water (or some other liquid) into the control knobs. Unplug, go to bed and try it again in the morning. If you continue to futz with it, you run the chance of burning out the electronics in the control knob, like I did. :(

Most of the time when I come out for a service call with this problem, it is usually because the burner cap is not seated properly on the base. Look at the burner and make sure there are no uneven gaps. Most of the time you will have to rotate the burner cap till a notch or pin "seats" into place. Most burner caps just sit on the bases, and so they get knocked off or moved when the cooktop is cleaned or installed. Hope this helps!
