will a bad solenoid in a thermador range stop it from sparking?
Answer Cathy, No, not really. If a burner igniter won't spark, you'll need to check the potentiometer 422748, or simmer control 422882 if the issue is with one of the simmer burners. It may also be an issue in the spark module 486771 if the issue is a "standard" burner.
Left front burner sparks, but no gas. The left rear sparks, gas and lights.
I am assuming it is the gas valve and potentiometer, but if this unit as a solenoid, how to get to it.?
Answer Bob, It's not the solenoid valve, were it the issue, the rear burner would not ignite or burn, were it the potentiometer or spark module, there would be no spark at the front burner. That pretty much leaves it to a faulty gas valve 415499 or clogged burner orifice 415498.
