Important Tips for Kenmore Models

  • Kenmore-specific support lists bake and broil element, sensor, control board, convection fan, and door seal as key parts for uneven heating issues.

Possible Causes

Faulty or damaged bake or broil heating element

How to Identify: Visual signs of damage (blisters, cracks or element not glowing red during operation; uneven heat patterns coincide with element location.

Part: Bake element, Broil element

Oven temperature sensor or thermostat miscalibration

How to Identify: Temperature readings using a separate oven thermometer differ significantly from set temperature; food is over/undercooked despite correct settings.

Part: Temperature sensor, oven thermostat

Poor air circulation or convection fan issues

How to Identify: Hot and cold spots throughout the cavity; convection mode doesn’t circulate air; fan doesn’t run or runs inconsistently.

Part: Convection fan/motor

Damaged or worn oven door seal

How to Identify: Heat escapes around door, longer cook times and inconsistent results; paper/dollar test shows loose seal.

Part: Oven door gasket/seal

Control board or sensor reading issues

How to Identify: Temperature regulation fluctuates unpredictably; sensor resistance readings out of spec.

Part: Oven control board
