Bosch Cooktop is producing a burning smell

When your Bosch cooktop has a burning smell, stop using it until you identify the source, especially if the odor is electrical or comes with smoke, sparking, or a hot control panel. The most likely cause is a failing control board, main control board, or oven control board. These boards use relays to send voltage to the surface element circuits, and a damaged relay can overheat or stop regulating power correctly. Next, check the surface element switch, which sends power to the surface element coil and may burn internally when defective. A failed surface element board is also possible, particularly when two or more burners stop working or produce an electrical burning smell at the same time. If only one burner is affected, inspect the element for continuity, then examine the element receptacle and wire kit for burned contacts, melted insulation, or damaged element prongs. Replace both the receptacle and element if the prongs are burned. This Bosch cooktop troubleshooting guide can help with a range burning smell or stove burning smell. Enter your model number to find the exact replacement part for your Bosch cooktop.

01 - Bosch Range/Stove/Oven Control Board

The control board has relays that send voltage to the surface element circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.

04 - Bosch Range/Stove/Oven Surface Element Switch

The surface element switch sends voltage to the surface element coil. If the switch is defective, the surface element will not work. If there is another element of the same size on the stove, try switching the elements. If the surface element still doesn’t work, the surface element switch is likely defective. The surface element switch cannot be tested or repaired—if you suspect the switch is defective, replace it.

Highly Likely

05 - Bosch Range/Stove/Oven Surface Element Board

The surface element board has relays that regulate the power supply to the burners. If one or more of the relays fails, the surface element won’t work. If two or more burners fail at the same time, this indicates that the surface element board is likely at fault. If only one surface element won’t work, use a multimeter to test the element for continuity. If the surface element has continuity, the surface element board might be defective.

Highly Likely

06 - Bosch Range/Stove/Oven Element Receptacle and Wire Kit

The surface element plugs onto a receptacle. Over time, the contacts in the receptacle can burn out. If the receptacle contacts burn out, the surface element will not receive power. To determine if the element receptacle has failed, inspect the receptacle contacts. If the contacts are visibly burnt or damaged, replace the element receptacle. In addition, examine the element prongs for signs of burning. If the prongs are burnt, replace both the element and element receptacle.
