Tim for Model Number SGCS304RS I have a Thermador model #SGCS304RS cook-top, and the front right burner sparks but no flame. I turn the burner on the indicator light comes on but I don't hear the solenoid click, also the dial turns a lot further than the other three do. This item is in a rental property so i'm wondering if someone forced it to far, could it need a new valve maybe? Is there a contact inside the valve that sends a signal to solenoid?
Answer Tim, you will want to test the potentiometer and the solenoid for DC voltage. If you turn the gas off before it enters the unit, then gain access to the inside of the appliance. With the switch placed on high, you will want to test for 110VDC at the solenoid by placing the black lead of a multimeter on the wiring going to the control and the red lead on the opposite wiring connection of the solenoid. If there is 110VDC, then you have a bad solenoid. If there is not 110VDC, then you can place the red lead at the connection of the controller labled line-5v and testing for 4VDC. If you do not have 4VDC, then you have a bad potentiometer, if you do have the voltage, then you have a bad controller. Read More... Answered by AppliancePartsPros.com | Wednesday, February 6, 2019
