The relay module is the switching hub of your Bosch range — it receives signals from the control board and switches power to the burner elements, oven bake element, and broil element. When a relay fails or the module burns out, one or more cooking zones stop responding entirely, even though the controls appear to work normally. OEM part 12024418 is the factory-correct relay module, restoring full heating function across all zones.
⚠️ Symptoms — Is This Your Part?
- One or more burners not heating despite the control showing active
- Oven not reaching temperature or not heating at all
- Broil element not activating
- Burning smell or visible scorch marks on the relay module board
- Range trips the breaker when a specific burner or oven is selected
- Intermittent heating — element works sometimes but cuts out randomly

💡 Pro Tip — Inspect the Element Before Replacing the Relay:
A failed bake or broil element can cause the relay to arc and burn out — if you replace the relay module without also testing the element for continuity, a shorted element will destroy the new relay module. Always test the heating elements first with a multimeter before installing the new relay. If an element shows no continuity or a visible break, replace it at the same time to protect the new module.

⚙️ Installation Notes
- Skill Level: Intermediate — requires accessing the rear or bottom panel of the range
- First step: Disconnect power to the range at the breaker before starting — relay modules carry line voltage
- Photograph all wiring harness connections before disconnecting
- Remove the rear access panel or oven bottom to locate the relay module
- Disconnect all harnesses, remove mounting screws, and swap the module
- Reconnect all harnesses fully until they click — partial connections cause intermittent faults
- Restore power and test all burners and oven functions before reassembling
- Estimated time: 30–45 minutes
