I have a 36" Thermador
Exactly what part you replaced.And was there any difference in the problem after and before replacing the part.
as per the problem the possible faulty parts can be Damaged igniter or faulty safety
1. The thermostat control.
2. The igniter.
3. The automatic valve (also called
the safety valve).
The thermostat, igniter, and safety valve
are wired in a series circuit.
• When the thermostat knob is turned to a
selected setting, electrical contacts in the
thermostat close applying power to the
series ignition circuit.
• With power applied, the ignitor begins to
heat. Electrical resistance in the ignitor
will decrease as the temperature of the
• Electrical current in the series circuit
increases in proportion to the drop in
• The igniter limits the electrical
current in the circuit to 3.3 to 3.6 amps.
The surface temperature of the ignitor will
be between 1800° and 2500°F.
• When electrical current has reached the
proper amperage, the automatic safety
valve will open, releasing main burner
• The ignitor stays energized while the
burner is lit. Once the selected
temperature is reached, the thermostat
contacts will open and remove power from
the ignition circuit. The automatic safety
valve will close after a few seconds, and
the burner flame will go out.
----------And the burner will relight when temp-reaches down from selected.But if the safety gas valve does not open then it will not relight, or if the igniter is weak then it will not relight.The gas pressure is low then it will not let the cook top to relight.When you turn the selector off and turn on,the whole system works as it gets a flow of current.But its not working automatically as it should.Also other possibility can be selector switch/know itself.----------
This possibilities are to be checked.Keep updated.Thanks.Helpmech.
