If the indicator light does not come on and you don’t hear a low humming noise as the door is being locked, it’s likely the oven’s touchpad is faulty and will need to be replaced.

Bosch Range/Stove/Oven Door Lock Motor and Switch Assembly

During the oven’s self-cleaning cycle, the door lock switch activates the door lock motor to prevent the oven door from being opened. If the door lock motor and switch assembly is defective, the oven door will not unlock once the self-cleaning cycle is complete. On most ovens, you can open the oven door by removing certain screws or panels. Check your owner’s manual for further instructions.

Bosch Range/Stove/Oven Temperature Control Thermostat

The oven thermostat sends voltage to the heating circuit and regulates the temperature of the oven during the self-cleaning cycle. It is possible for the oven thermostat to function properly for baking and broiling but not for cleaning. Due to its complexity, the oven thermostat is difficult to test. If you suspect the oven thermostat is at fault, replace it.

Bosch Range/Stove/Oven Door Latch

For your safety, the self-clean cycle will not begin unless the oven door is locked. If the door latch is broken and unable to allow the door to be locked, the self-clean cycle will not begin. Inspect the latch for damage. You can also use a multimeter to test the latch assembly’s microswitch, if applicable, to determine if the switch has appropriate electrical continuity. If the latch is damaged or the microswitch tests negative for continuity, the door latch should be replaced.

Bosch Oven Faulty Heating Elements

Bosch Oven Major Issues

Bosch Oven Faulty Heating Elements

A Bosch oven not heating properly not means you have a dilemma to resolve, and most likely on an empty stomach. Fortunately, we can solve both problems ASAP with our Bosch oven troubleshooting guide. From a lack of power to a blown thermal fuse, we’ll pinpoint your Bosch oven heating problems.

HOW TO TROUBLESHOOT A BOSCH OVEN NOT HEATING PROPERLY

Whether it’s insufficient heat, unevenly cooked food, or no heat at all, a Bosch oven not heating properly feels like a worst-case scenario. However, many heating issues can have a simple and straightforward solution when you know where to begin. Our guide gives you the starting points you need to execute a fast fix.

#1 – No Power To Bosch Oven

When asking, “Why won’t my Bosch oven heat up?” sometimes the answer lies with your power source and not the oven. If your Bosch oven isn’t receiving power, it won’t be able to provide heat. Here’s how to check your power sources to make sure your oven has adequate electricity:

  • Make sure your oven is properly plugged in.
  • Refrain from using an extension cord with your oven, as most cords can’t safely transmit the electricity an oven requires.
  • Check your circuit breaker for blown fuses or tripped breakers, especially if you experience a power outage.

#2 – Bosch Oven Clock Reset

After a power outage the clock on your oven will revert to its factory setting and flash “00:00.” Your Bosch oven will not operate until you reset the clock’s time and “00:00” is no longer flashing.

#3 – Bosch Oven Not Calibrated Correctly

If you’re dealing with long cooking times, undercooked food, or food that’s not cooked evenly, it’s possible the oven thermostat needs recalibrating. Recalibrating your oven can better enable the temperature setting to match the oven’s internal temperature and facilitates more accurate cooking times.

Most ovens can be recalibrated in increments of 35°F at a time via your control panel. Check your owner’s manual for the exact calibration steps for your model oven. If recalibrating doesn’t fix your Bosch oven not heating up, there’s a small chance your oven thermostat is faulty and requires replacement.

#4 – Blown Oven Thermal Fuse

The thermal fuse on your Bosch oven is a protective feature that prevents the oven from overheating. The thermal fuse will blow if the oven gets too hot, cutting power to the oven and forcing it to cool down.

An oven’s thermal fuse can blow when exposed to the high temperatures of a self-cleaning cycle. To prevent this occurrence, the best way to clean an oven avoids the self-cleaning feature altogether. A thermal fuse can also blow if the fuse is faulty. In either case, if multimeter testing reveals a lack of continuity, the fuse must be replaced.

#5 – Oven Component Malfunction

If these troubleshooting tips still leave you with a Bosch oven not heating properly or that leaves food unevenly cooked, it’s possible a broken part is to blame. These components can leave you with heating problems when they malfunction:

  • Heating elements: The heating elements at the top and bottom of an electric oven work together to create even heating, while the top element also broils food. If one of these elements breaks or malfunctions your oven won’t heat up properly or not heat up at all. Heating element malfunctions are diagnosable by a lack of continuity. You may also notice visible damage or a lack of red glow in the heating element.
  • Convection motor: Convection ovens use a fan to circulate heat throughout the oven’s interior, resulting in more even heating and faster cooking. If the motor that powers the fan malfunctions, the fan won’t operate and the oven’s air won’t circulate, resulting in improper heating.

In either instance, these components cannot be repaired and require replacement. We recommend professional service for these complex repairs.

Bosch Oven Temperature Inconsistencies

Bosch Oven Major Issues

Bosch Oven Temperature Inconsistencies

Bosch Range/Stove/Oven Bake Element

When the bake element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the heating element has burned out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has burned out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.

Bosch Range/Stove/Oven Control Board

An oven’s control board will often be used to send voltage to the bake and broil elements or the igniters to heat the oven to the designated temperature. When a temperature sensor senses that the oven has reached the appropriate temperature, the control board should shut off the voltage to the heating circuit. If the control board is defective, the voltage may be shut off too early or not at all, resulting in an inaccurate oven temperature. You should test the temperature sensor and other components first before considering replacing the control board. If you confirm the other components are working properly, you can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance’s wiring diagram.

Oven calibration needed

The first thing to consider is that oven temperature will fluctuate throughout the cooking process. This is normal. To verify oven temperature, it is best to use a digital thermometer with the wire lead end touching a cast iron skillet to keep the temperature reading even. You can use a dial thermometer, but they are slow to react and are not as accurate as a digital one. Heat the oven to 350 degrees Fahrenheit. Let the oven cycle on and off for at least 20 minutes. Check the temperature. If the oven temperature is over or under by 35 degrees Fahrenheit the oven thermostat, oven sensor, or oven control (depending on the model), is likely bad. If the temperature is within 35 degrees above or below the set temperature, it can likely be recalibrated succcessfully. Refer to your owner’s manual.

Bosch Range/Stove/Oven Igniter

The igniter draws electrical current through the gas valve to open it. As the igniter weakens over time, it takes longer to open the gas valve. As a result, the oven temperature will drop too low before the burner reignites. The oven temperature should not drop more than 40 degrees Fahrenheit before the igniter relights the burner.

Bosch Range/Stove/Oven Broil Element

The broil element may have burned out. When the broil element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the element has burned out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.

Bosch Range/Stove/Oven Main Control Board

A range’s main control board will often be used to send voltage to the bake and broil elements or the igniters to heat the oven to the designated temperature. When a temperature sensor senses that the oven has reached the appropriate temperature, the control board should shut off the voltage to the heating circuit. If the control board is defective, the voltage may be shut off too early or not at all, resulting in an inaccurate oven temperature. You should test the temperature sensor and other components first before considering replacing the control board. If you confirm the other components are working properly, you can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance’s wiring diagram.

Bosch Range/Stove/Oven Temperature Control Thermostat

The temperature control thermostat monitors the temperature inside the oven and cycles on the heat when the oven temperature gets too low. If the temperature control thermostat is not calibrated correctly, it won’t cycle on the heat at the proper time. As a result, the oven temperature might be too high or too low. Due to its complexity, the thermostat is very difficult to test.

Bosch Range/Stove/Oven Temperature Sensor

The oven sensor works in conjunction with the oven control board to regulate the temperature. The sensor regulates the oven temperature by varying its resistance to electrical current as the oven temperature varies. As the oven temperature rises, the oven sensor creates greater resistance. If the sensor gives the wrong amount of resistance, the oven may not bake evenly. On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner’s manual for instructions on how to recalibrate the oven control.

Bosch Range/Stove/Oven Oven Control Board

The oven control board works in conjunction with the oven sensor to regulate the temperature. The sensor regulates the oven temperature by varying its resistance to electrical current as the oven temperature varies. As the oven temperature rises, the oven sensor creates greater resistance. If the sensor gives the wrong amount of resistance, the oven may not bake evenly. Or if the oven control board does not read the sensor resistance correctly, the oven temperature may be inaccurate. On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner’s manual for instructions on how to recalibrate the oven control.

Bosch Range/Stove/Oven Convection Element

In a convection oven, the convection element works with the other heating elements to heat the air circulating inside the oven. If the convection element is burned out, the oven won’t heat evenly. To determine if the convection element is burned out, use a multimeter to test the element for continuity. If the convection element does not have continuity, replace it.

Bosch Range/Stove/Oven Convection Motor

In a convection oven, the convection motor drives the convection fan to circulate the air inside the oven. If the convection fan isn’t circulating the air, the oven won’t bake evenly. Try turning the convection fan blade by hand. If the blade is hard to turn, this may indicate that the motor bearings are worn. If the motor bearings are worn, you will have to replace the convection motor. To determine if the motor is defective, use a multimeter to test it for continuity. If the motor does not have continuity, replace it.
