Gint for Model Number PRG366 Thermador My range top originally sparked randomly at all times of the day and night, especially when the oven was on. I replaced the spark module and the left rear ignitor. While it appears the random sparking at odd times is gone, a hot oven still starts the sparking on the range top. The sparking usually stops after about 15 seconds, but occasionally I need to cycle the circuit breaker to turn off the sparking. Where else do I need to look? What else might need to be replaced?
Answer Hi Gint. It sounds like you have the positive wire and the negative wire reversed on the spark module when you reinstalled it. Check the module with a magnifying glass for a positive mark and a negative (-) mark. The white goes on the negative terminal (or neutral), the black wire goes to the positive. If this is OK, then the same goes with the house outlet. The outlet terminals can be reversed and not polarity correct. The narrower terminal will be the black wire attached to the brass screw. The white wire should be attached to the silver color screw (neutral at the wide female terminal). This should stop the sparking. Let us know how we can assist. you further. Thank You. Read More...
