Bosch Range/Stove/Oven Circuit Board & Timer Parts

Bosch Range Control Board & Oven Timer Parts

The control board (also called an ERC or electronic range control) is the brain behind every heating cycle and safety interlock on your Bosch range. When it fails, you'll notice error codes on the display, unresponsive buttons, incorrect oven temperatures, or the range won't start at all. Bosch 500 and 800 series models are particularly common in kitchens where precision matters — and their control boards reflect that factory-certified engineering.

Finding the exact OEM board for your Bosch model is critical. Aftermarket or cross-brand boards won't communicate with your range's sensor network. Use your model number to confirm the correct circuit board assembly, and you'll restore full oven and cooktop function. Bosch Range Stove Oven Circuit Board Timer Parts covers everything from the main ERC to display panels and relay modules.

• No display or unresponsive buttons: Control board has lost communication; test power to the board first
• Error codes (E01, E09, E15, E24, E25): Sensor or heating element circuit failure; error code + model number pinpoints the exact part
• Oven won't heat or heats to wrong temperature: Board not signaling the bake or broil element; or temperature sensor is failing
• Range won't start or stops mid-cycle: Safety interlock or timer circuit on the board has tripped or failed
• Cooktop burner won't ignite or one burner is dead: Surface element relay or ignition circuit on the board is open

Bosch Range Control Board Questions & Answers

How do I know if my Bosch range control board has failed?

A failed Bosch control board often shows itself as a dead display, unresponsive touch controls, or cryptic error codes like E01 (shorted sensor) or E15 (open sensor circuit). You might also see the oven heating wildly out of control, or refusing to heat altogether. Sometimes the range will start a cycle and then stop unexpectedly. If you've tested power to the board and the display is still dark, or buttons don't respond when pressed, the ERC is the most likely culprit. Bosch boards are model-specific — enter your exact model number into Repair Clinic's lookup to get the right replacement.

What's the difference between Bosch 300, 500, and 800 series control boards?

Bosch 300 series ranges use simpler mechanical or basic electronic controls, while 500 and 800 series boards are far more sophisticated — they run convection timing, self-clean cycles, and sensor diagnostics. An 800 series board is not compatible with a 300 series range, even if the physical connector looks similar. The software and relay configuration are different. This is why model number verification is absolutely essential: a $50 control board for a 300 series will not work in an 800 series, and vice versa. Always enter your full model number to confirm compatibility.

Can I replace a Bosch range control board myself?

Yes — removing and replacing the ERC is straightforward for most Bosch ranges. You'll disconnect the wire harness (usually 2 to 4 connectors) and unscrew the board mounting bracket. No special tools required. However, the board must be the exact OEM replacement for your model, and you may need to access the control panel from the front or back of the range depending on the design. If you're unsure about opening up your range, a technician can confirm the board failure and install it in under an hour. The real cost is the part itself — OEM Bosch boards run $150 to $350 depending on the series.

Why does my Bosch range keep showing error codes even after I clear them?

Recurring error codes mean the underlying sensor or circuit problem hasn't been fixed — the board is working correctly by alerting you to the fault. For example, an E09 code often points to an open bake element circuit or a failed temperature sensor, not a board failure. Before replacing the control board, use the error code + your model number to check whether a heating element, thermistor, or wiring harness is the real culprit. If you've confirmed all sensors and elements are intact, then the board itself has a failed relay or circuit and needs replacement. Repair Clinic's lookup will guide you to the right diagnostic path.

Bosch Range/Stove/Oven Model Number: Where to Look

On Bosch ranges, stoves, and ovens, check the oven door frame, the side of the open door, or behind the storage drawer for the model and serial number label. Keep the complete model number handy, including any letters, numbers, or slash marks, since similar Bosch units can use different parts. Enter it in the model number search to pull up the parts matched to your unit across the full range, stove, or oven catalog. This filters out parts that do not fit your appliance and helps you select the correct replacement with less cross-checking. It is the quickest way to be sure the part fits before you order.
