Bosch Range Surface Element Switch / Energy Regulator / Infinite Switch 629049 – Superseded by 00629049

Bosch electric range surface-element control switch, also described as an energy regulator or infinite switch. It regulates electric surface-burner heat from low to high power levels.

Is This the Right Part?

Common Symptoms

• Surface burner does not heat
• Surface burner will not turn off
• Burner temperature is erratic or does not match the selected setting
• Burner fails to respond when the control knob is turned

Check Before Replacing

• With the appliance disconnected from power, verify that the control knob is firmly engaged with the switch shaft and is not cracked or slipping.
• Compare the affected burner’s behavior with another burner using a similar setting; differences can help identify whether the issue is localized, though they do not by themselves confirm a failed switch.
• Inspect the visible control area for heat damage, discoloration, or a loose knob; do not operate the appliance if wiring or insulation appears damaged.
• Confirm the appliance model and the switch markings/terminal arrangement before ordering or installing a replacement.
