The Simmer Control is an OEM component specifically designed for Bosch ranges. It regulates gas flow to provide the lowest possible flame setting needed for delicate cooking tasks. Precise control allows for uniform, attentive simmering.

Symptoms of a bad simmer control include inconsistent or unadjustable flame heights on low settings. Cracks, damage, or wear of internal mechanisms over time can also cause unstable flame control.

Causes of bad simmer control can be normal wear and tear issues like dirt buildup impeding mechanisms. Accidental impact or overheating leading to cracks are other causes for replacement.

Symptoms of a bad simmer control include:

  • Flames that surge or fluctuate below the lowest settings   
  • Inability to adjust the flame down sufficiently low
  • Burners that shut off or cause overflow flooding on low-heat  

This OEM Bosch part is also compatible with Thermador and some Kenmore ranges. Replace for dependable, Fine-tuned low-heat performance.

James C. for Model Number PDR484GGZS/07

When I turn on my griddle, I get no ignition or gas. We have tried the following parts with no success. AP28333971, a gas tap, AP3782867 a Thermostat-griddle, and a part I have not received, AP3782975 a potentiometer . I can't locate this part and could use your help in locating it. They also recommended an AP45359679 if the last part doesn't work. I would appreciate it if you can think of any other part that might be causing the problem Since I purchased over $200.00 in parts, and had to return them for credit. Thanks for your help

Hello Jim, Part number 00645446 is an available part and even shows in stock. This is the redesigned version of the potentiometer. It is the part you will have to order for the "start switch" for this model. The AP3782975 will not work in this application as per the parts cross from Thermador.

Mark for Model Number SGSX456

Customer reports that unit start "sparking" all by it's self at varying times of the day and night but very intermitantly otherwise when being used works fine. Turing power to unit OFF then ON again solves the problem---untill the next time. Both potentiometers have been replaced and no spark switches are "shorted". It must be either the Control Module or the Spark Module--but which one? If I try what you suggest and that does not solve the problem can I return the part? Thanks, Mark

Hello Mark. Check and make sure there is no moisture in the unit. If there is moisture there, it will cause the unit to spark like that. If there is no moisture there, you will need to replace the control unit 00645446 on the unit. Also, make sure none of the switches are bad on the unit or have any moisture in them.

Hi Gra. Your spark switch that is on the burner valve shaft may be shorted. Its job is to send the voltage to the ignition module as you are calling for ignition. Part # 00189008. You can also temporarily unhook one side of the sw. wires and tape it with elect. tape to test to see if this is the issue or possibly the control unit part # 00645446. Thank You.
