If you are an owner of an oven that uses convection heating, you may already know that it uses a fan that circulates the hot air around the tub during the cooking process. In fact, convection ovens are popular with homeowners because they can provide even heating to multiple dishes at one time.
However, the fan will eventually fail due to overuse or lack of maintenance. When that happens, it will have different and have potentially disastrous results on your dishes. So, if the fan in your oven is no longer working properly or it is blowing cold air rather than hot air, then it is malfunctioning. However, to make the right repair, you need to be able to troubleshoot the faulty part.
Faulty Heating Element
The fan in convection ovens is usually installed by its own heating element. Therefore, a faulty heating element is the easiest problem to diagnose. So, when you notice the fan in your oven is blowing cold air, your heating element might have some issues.
Another important part to check is the convection element which is located at the top of the oven tub, but it is usually located at the back wall of some models. Since this part is located in an awkward spot, you will need to remove your oven door first because that could get in the way. You will also need to unlock the latches at the bottom corners before pulling them up and out.
After you have removed the panel, you should now be able to see the heating element. If there are visible damage on the element like bubbling or burning on the coil, it could mean that the part is already damaged inside its casing. You can further test it by using a multimeter to see if it is really faulty.
To check if the faulty part is the motor of your convection oven, you will need to remove the top panel first, where you can visually inspect the fan. If the part is full of dirt, it may be obstructing the normal flow of air, or it could even stop the fan from turning.
To reach the main motor of your oven, you will need to remove the back panel on the outside behind where the fan is located. If the fan is not obstructed or dirty, then the motor might be malfunctioning.
Overall, we recommend that you contact a reliable and licensed oven repair specialist since they have the equipment and expertise to diagnose and repair your oven. Also, the repair cost will be based on the part that needs to be repaired or replaced by the technician.
