Bosch Range HES252U Oven not heating evenly

This heating element is the oven/dryer heater assembly that restores heat generation so your appliance can reach and maintain operating temperature. It replaces a failed or damaged element to recover normal heating performance. What it does

• Converts electrical power into heat for the appliance's cooking/drying cycle
• Commonly used when the appliance no longer reaches temperature or heats unevenly
• Works as the primary heating component that cycles on and off per the appliance's controls

• One heating element assembly

• Disconnect power (unplug or switch off circuit breaker) before starting any work
• Access typically requires removing an access panel or interior trim—follow your model's service instructions
• Handle terminals and ceramic/metal surfaces carefully; avoid bending or contaminating contact points
• Test for continuity with a multimeter after removal to verify failure before installing

The Sensor is an OEM part for Bosch ovens and ranges. It detects and monitors the actual interior temperature to maintain precise baking and roasting conditions.

Causes of a bad temperature sensor can include wear from prolonged heat exposure within the oven cavity. Physical damage, moisture intrusion or circuitry malfunctions may also lead to sensor failure over time.

Symptoms of a bad oven temperature sensor include:

• Inability to accurately read or achieve set target temperatures
• Fluctuations in readings displayed
• Cooking modes like bake and broil functioning abnormally

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

This heating element is the direct-replacement heater assembly that provides the heat source for compatible appliances, restoring proper heating so cycles reach the temperatures needed for effective drying or cleaning. What it does:

• Generates heat for the appliance's thermal system (air or water heating depending on model).
• Replaces a failed or damaged heater element to restore normal temperature rise.
• Common symptoms it may fix: no heat, weak/no drying or cleaning performance, or unusually long cycles.
• Works as part of the appliance's safety and temperature-control circuit (thermostats or sensors may also be involved).

• Always disconnect power (and water, if applicable) before replacing the element.
• Allow the appliance to cool fully and wear protective gloves; heating elements can have sharp edges.
• After installation, restore power and run a short test cycle to check for any error codes.
