Official Bosch range parts

Most common Bosch electric range parts and Bosch dual fuel range parts that need replacing

1. Surface element switch. The surface element switch (also called a surface burner switch or infinite burner switch) is mounted on the control panel of an electric range or cooktop. It's an electrical switch that turns on and off the associated surface element and also controls the how much heat the element produces.
2. Thermal fuse. Many ovens have a bi-metal thermal fuse that protects the oven from overheating. The oven thermal fuse trips when the controls aren't working properly and the temperature in the oven gets too hot.
3. Relay control board. Some Bosch ranges have a relay control board that's separate from the timer and control board. The relay board has electrical relays (switches) that control voltage going to major loads such as the bake element or a surface element, based on signals from the control board.
4. Radiant surface element. The radiant surface element is mounted on the bottom of a ceramic glass cooktop and provides heat for that area of the cooktop. It's controlled by a surface element switch (also called a surface burner switch or infinite burner switch). The radiant surface element has a limit switch that shuts off the element to protect the ceramic glass cooktop from overheating.
5. Oven door light switch. The oven door light switch is a plunger switch on the frame of the oven above the opening to the oven. The oven door pushes the oven light switch plunger in when the door is closed to turn the light off. When the door is open, the plunger is released and the light is on.

How to fix your Bosch electric or dual fuel range when the broiler won't work

A broken broiler element or failed electronic oven control board could prevent the broiler from working in an electric range.

A broken oven temperature sensor probe also may prevent the broil element from heating or staying on in oven. When the oven temperature sensor probe fails, you'll likely see temperature control problems in the bake mode as well.

You can test the oven temperature sensor probe by unplugging the range and measuring sensor probe resistance using a multimeter. You should measure about 1,080 ohms of resistance through most probes at room temperature. Refer to the tech sheet for the probe's resistance specification for your range. You can likely find the tech sheet in the control console or taped to the back of the range. Replace the oven temperature sensor probe if you don't measure the correct resistance through the probe. If the probe is okay, then you may need to replace the electronic oven control board.
