  • Control Board: Regulates power to the oven elements, initiates self-cleaning, and displays time and temperature settings.
  • Temperature Sensor: Monitors the oven’s internal temperature.
  • Broil Element: Located at the top and primarily used for browning food.
  • Bake Element: Located at the bottom and responsible for most of the cooking heat.
  • Convection Fan (in convection ovens): Circulates air around the oven for even cooking.


Temperature Regulation:

  • The temperature sensor, a thermistor, plays a crucial role. The control board sends an electrical current through it to measure the oven’s temperature based on resistance.
  • If the sensor’s resistance deviates from expected values, the control board might misread the temperature, causing the oven to either overheat or underheat.

Error Detection:

The control board can detect issues with the oven and will display error codes to indicate potential problems. These codes guide users on where the problem might lie but don’t pinpoint the exact malfunctioning component.

Reasons Electic Ovne won’t Turn On

Insufficient Voltage:

Electric ranges typically require 240 volts of alternating current, split between two legs, each carrying 120 volts. If one leg is interrupted due to a tripped breaker or blown fuse, the oven might not power on.

Faulty Electrical Outlet:

If the electrical outlet doesn’t provide the necessary voltage (usually between 210 and 240 volts), the oven might not function.

Burnt or Loose Wire Connection:

The bake or broil power supply wires can burn out near the heat source, resulting in visible damage. If these wires are damaged or have a loose connection, the oven might not operate.

Blown Thermal Fuse:

Some oven models have a thermal fuse that can blow if the oven becomes excessively hot. This would shut off the power to the oven. A blown fuse won’t have electrical continuity and will need replacement.

Defective Thermostat or Sensor:

The oven temperature is regulated by either a thermostat with a sensing bulb or an electronic control board paired with an oven sensor. If these components malfunction, the oven may not maintain the right temperature or might not turn on at all. For instance, if the sensor doesn’t display approximately 1,100 ohms of resistance at room temperature, it might be faulty and require replacement.

Malfunctioning Oven Control Board:

If all other components are functional, the issue might lie with the oven control board. While this board isn’t easily testable, visible signs of burning or a shorted-out component can indicate a malfunction.

Troubleshooting Electric Oven Not Heating

Step 1: Test Both Settings: Check both the bake and broil settings. If either doesn’t work, it’s likely due to a faulty element.

Step 2: Check Both Elements: If neither the bake nor the broil settings are heating, but the cooktop is functioning, it indicates the oven is still receiving power. The problem could stem from the thermal fuse, the temperature sensor, or the control board.

Step 3: Understand the Oven’s Mechanism: The heating element warms up due to electrical resistance when electricity passes through it. The control board supplies 120 volts to the heating elements and, based on input from the temperature sensor, will cycle these elements on and off to maintain the set temperature.

Step 4: Temperature Sensor: A faulty temperature sensor can prevent the oven from heating. For Whirlpool models, a sensor malfunction might result in an F3E0 or F3E1 error code. For Frigidaire and General Electric models, you might see an F3 or F4 error code. Consult the oven’s manual if you’re unsure about any error codes.

Step 5: Control Board: A malfunctioning control board might not supply power to the heating elements. Inspect the board for any visible damage or burnt areas. Ensure all wire connectors are firmly in place.

Step 6: Thermal Fuse: Some oven models feature a thermal fuse or a high-limit switch that cuts power to the oven if it overheats. The thermal fuse, generally located near the bake or broil element terminals, can be tested for continuity using a multimeter. If it doesn’t register a reading between 0 and 1 ohm, it needs replacement.

Step 7: Testing the Oven Sensor:

  • Find the oven sensor, usually positioned near the broil element.
  • Disconnect its wires and measure its resistance using a multimeter. At room temperature, the resistance should be around 1100 ohms. If the resistance falls outside the 1000 to 1200 ohm range, replace the sensor.

Troubleshooting Oven Display Not Working

Step 1: Check Basic Functions: Test all oven functions: the bake, broil settings, and each stove element. If nothing operates, it might be a power supply issue. Refer to linked resources for no-power scenarios.

Step 2: Ensure Adequate Power Supply: Stove elements run on separate circuits and aren’t influenced by the control board. If they function, it indicates your range is receiving the full 240 volts of power.

Step 3: Attempt a Power Reset: Following power outages, try resetting the oven. Switch off the breaker, wait five minutes, and turn it back on. This can sometimes reset the control board.

Step 4: Check the Clock Display: The clock might simply be disabled. Pressing the clock button for about five seconds typically activates the display. For exact steps, refer to your oven’s manual.

Step 5: Inspect Thermal Fuse: Some ovens have a thermal fuse that trips if the oven overheats. Depending on its connection, a blown fuse can affect heating elements, the control board, or the display. Use a multimeter to check the fuse for continuity. If the multimeter doesn’t display a reading between 0 and 1 ohm, the fuse should be replaced.

Step 6: Check Wiring to Control Board: Inspect wires leading to the control board, starting from the terminal block. Look for burnt or frayed wires and replace or repair them as needed. Test each wire for continuity from the terminal block to the control board. Damaged wires should be repaired or replaced.

Step 7:Examine the Control Board:

  • Visually inspect the control board for burnt or blackened spots, which could indicate a failed component.
  • Ensure all wire connectors are secure.
  • If the board appears damaged, especially after a power surge, consider replacing it. If unsure, it’s advisable to consult a professional.

Step 8: Reassemble and Test: After checking and making necessary replacements, reassemble any opened sections, plug the oven back in, restore power, and test the oven.

Troubleshooting Oven Not Baking Evenly

Step 1: Assess Basic Functionality: Test all oven functions, including the bake, broil settings, and stove elements. If the entire oven doesn’t function, the issue could be with the power supply.

Step 2: Understand Oven Heating Mechanisms:

  • Electric ovens use heating elements that generate heat due to electrical resistance.
  • The control board, post-preheating, monitors the oven’s temperature sensor and cycles the heating elements on and off to maintain the set temperature.
  • The broil setting mainly browns food from the top, while the bake setting uses both elements, mainly heating from below.

Step 3: Recognize Natural Oven Variances:

  • Ovens may have areas with slight temperature differences due to how air dissipates heat.
  • Pan size, type, and rack spacing can impact the air temperature around the food.
  • In convection ovens, a fan circulates air. If this fan malfunctions, baking can become uneven.

Step 4: Check for Element Issues:

  • A faulty heating element can lead to uneven baking.
  • Use a multimeter to test the element for continuity. If there’s a break or if it’s shorting to the oven’s frame, the element should be replaced.

Step 5: Inspect the Thermal Fuse or Limit Switch: Some ovens use a thermal fuse or a high limit switch that cuts power if temperatures rise too high. Using a multimeter, check for continuity. If the fuse or limit switch lacks continuity, it should be replaced.

Step 6: Examine the Control Board: A visual inspection can reveal burnt or blackened spots, indicating a malfunction. Ensure wire connectors are securely attached. If you suspect damage, especially after a power surge, consider replacing the board or consulting a professional.

Troubleshooting Oven Overheating

Step 1: Understand the Oven Heating Mechanism:

  • Electric ovens work by passing electricity through heating elements. The resistance in the element material produces heat.
  • After the oven preheats, the control board uses the temperature sensor to cycle the elements on and off, maintaining the desired cooking temperature.

Step 2: Identify the Heating Settings:

  • The broil setting primarily uses the broil element to brown food from the top.
  • The bake setting uses both the broil and bake elements, with the primary heat coming from the bake element below.

Step 3: Air Circulation and Heating Variance:

  • Ovens can have natural cool and hot spots due to how air dissipates heat.
  • The size and type of pan, as well as rack spacing, can influence the air temperature around the food.
  • In convection ovens, a blower fan circulates air. If the fan isn’t functioning, the oven might not heat evenly.

Step 4: Diagnose Possible Causes of Overheating:

Faulty Heating Element: If an element is malfunctioning, it might cause the oven to overheat. Use a multimeter to test the element for continuity. If it’s faulty or shorting to the oven’s frame, it needs replacement.

Defective Temperature Sensor: If the oven’s temperature sensor is malfunctioning, it might not provide the correct feedback to the control board, leading to overheating. You should check if the sensor is functioning correctly.

Thermal Fuse or Limit Switch: Some ovens use a thermal fuse or a high-limit switch that cuts power when the oven overheats. If these components are faulty, they might not cut off the power, leading to overheating. Test them for continuity using a multimeter.

Control Board Issues: A malfunctioning control board might not regulate the oven’s temperature properly. Look for signs of damage, charred or blackened spots on the board. Ensure all wire connectors are secure. If in doubt, consider getting the control board inspected or replaced.
