Customer Questions and Answers for Potentiometer Kit by Bosch

Hello Hami. Turn the rear extra low burner knob to "HI" and check between POT2 & LINE 5 at the simmer controller 00497235. The voltage should be 1.5 VDC if the solenoid is on. Warning: POT1, POT2, and LINE 5 are carrying 120 VAC. Repeat the process for the front burner. The reading between POT1 and LINE 5 should be 1.5 VDC. If not, check voltage on solenoid 1 and solenoid 1 RET on the simmer controller. The voltage should be between 85 to 105 VDC. Repeat for Solenoid 2 and solenoid 2 RET on the simmer controller. If there is no voltage there replace the controller.

If the first test was good, and the 1.5 VDC was at both checks, you will turn the rear burner to "XLO" and check for 5 VDC between POT2 & LINE 5. Repeat for the front burner, but you will test from POT1 & LINE 5 for the front burner. If the voltage is good, does the solenoid operate 5 to 10 seconds and then off for 50 to 55 seconds. If not, you will need to replace the simmer controller. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
