How To Fix An Oven With Little Or No Heat When Baking

The appliances we use in our kitchen are an important part of a modern kitchen, and it’s hard to imagine a life without these devices. Today, most homeowners have a stove, oven, refrigerator, and range in their kitchen. They use these appliances to cook and store their dishes. However, like any other residential appliances, these appliances can also malfunction. Repairing these machines is not easy, as they require high voltage checks. If your range is not working, it is best to get a range repairman to rectify the problem. However, there are some problems that you can troubleshoot without professional help. To troubleshoot the problem, you must be able to identify the problem part and replace it with a genuine spare.

One of the problems you are likely to face with your oven is that it produces little or no heat when baking. To fix this issue, you must have a basic understanding of how the oven functions and details the parts that are likely to cause this problem. In this article, we provide you with useful hints that help in identifying the problem part.

Bake Element

If the oven is producing little or no heat, the first part you must check is the bake element. The bake element is typically located at the bottom of the appliance. The oven uses both broil and bake element to complete the baking cycle. Even though both broil and bake elements are used for baking, the majority of heat is produced by the bake element.

When there is a problem with the bake element, the oven may not provide heat or take longer to reach the desired temperature. Also, the food may burn on the top when the bake element is damaged. To check if the bake element is defective, you must do a visual inspection of the part. If the element is separated or blistered, it means that it is damaged and must be replaced.

If you don’t notice any signs of damage, you must turn on the bake function for a few minutes and turn it off. If the element does not show any evidence of heating, it indicates that the element is defective. To check the condition of the bake element, disconnect the power supply to the machine. You must then remove the back panel and check the wires that connect to the element. If the wires are corroded, you must replace the cables. If there is a loose contact, you must take steps to ensure the wires are connected securely. You must then check the condition of the element. If there are no visual signs of damage, you must check the condition using a multi-meter. If the element is burned or damaged, it will not have any continuity, and it must be replaced.

If there is no problem in the element, you must check the condition of the bake circuit. Since this involves live voltage checks, it must be done by an oven repair service technician. Some of the components that must be tested include fuses, thermostat, and few other electronic controls.

Oven Control Thermostat

The oven control thermostat is a part of the main control board of the machine, and it controls both the bake and the broil element. The thermostat is a temperature controlled switch that has contacts which supply power to the bake and broil element. If the thermostat is damaged, it will produce too much, too little, or no heat at all.

If you notice that bake element is cold or is too hot even when baking cycle is turned on for a few minutes, it indicates that thermostat may be at fault. Before you check the thermostat, make sure you check all other components that are likely to cause this problem. Some controls of the thermostat can be calibrated up to 52 degrees Fahrenheit; however, you will need a thermometer to carry out this task.

The temperature adjustment screws are located on the back of the thermostat. However, if the back of the part is sealed, it indicates that temperature cannot be manually calibrated. Before performing any test or calibrating the thermostat, make sure you remove the power supply to the home appliance. If the bake or broil element does not receive any power, you must check the appropriate contacts of the thermostat for continuity using multi-meter.

Temperature Sensor

The temperature sensor helps in maintaining the temperature inside the oven. When the desired temperature is reached, the sensor signals the electronic controls to turn off the power supply to the broil and bake element. If there is a problem with the sensor, it will produce little or no heat. The sensor can be found near the broil element.

At times, the appliance may display a fault code when the sensor is malfunctioning. If you notice an error code, you can use a multimeter to check the resistance of the part. Before you test the resistance, make sure you disconnect the power supply to the machine.

Electronic Control Board

The electronic control board is an important part of the oven, as it controls all the essential functions of the appliance. The board not only operates the broil and the bake elements, but other parts that control the temperature inside the machine. If there is no power to the elements, you must check the electronic control board to verify if there is power at the appropriate relays. Since this is a live voltage check, it must be performed by oven repair technician. If there is erratic or no output voltage, then you must replace the electronic control board.

Fuses

Most modern ovens have an internal fuse that will blow up when there is a component or wiring problem. If you notice a blown fuse in the machine, it means that a component has shorted and the problem must be rectified. Ovens that have fuses will have a diagram that indicates the part that affect a particular fuse. If the fuse is blown, you must check the diagram to find out the part you must replace. When replacing the fuse, make sure you don’t change the rating of the fuse.

If these steps don’t help, it is best to get help from a household appliance repair company. These companies have several microwave technicians that will visit your home to repair and service the appliance.
