Why Isn't My Oven's Convection Function Working Anymore?

Jul 28, 2023, 15:38pm

The oven reaches very high temperatures to heat and cook the food inside. It is designed to withstand this temperature change for a very long time.

It thus has several resistances allowing heating according to a type of cooking chosen beforehand: the resistance of sole, vault, grill and convection heat. A propeller that will turn to heat the interior of the oven as a whole and diffuse the heat.

The convection function may no longer work. It will then be necessary to check several elements likely to cause this breakdown.

The introduction of the convection function in ovens marked a significant advancement in home cooking technology. With a convection oven, you can cook food more evenly and reduce cooking times, thanks to a built-in fan that circulates hot air. However, like any other mechanical feature, the convection function might sometimes fail to work as expected. This article will shed light on why your oven’s convection function may not be working and what steps you can take to resolve the issue.

Why Isn't My Oven's Convection Function Working Anymore?

Understanding the Problem

Before we delve into the possible causes of a non-functioning convection function, it’s essential to recognize what constitutes ‘not working.’ If your oven’s fan isn’t spinning, the oven isn’t reaching the set temperature, or the cooking results are uneven, you may be experiencing a problem with the convection function.

Possible Causes and Solutions

1. Faulty Convection Fan

In convection ovens, the fan plays a vital role by circulating hot air for even cooking. If the fan isn’t spinning or makes unusual noises, it could be faulty or obstructed.

Solution: If the fan isn’t spinning, check for any obstructions. If it’s clear but still not working, it might be time for a replacement. In this case, it’s best to enlist the help of a professional appliance technician to handle the replacement safely.

2. Failed Fan Motor

The fan motor powers the convection fan. A failure in the fan motor could lead to the fan not spinning, thus disabling the convection function.

Solution: If the fan motor is defective, it will need to be replaced. Again, because this involves dealing with electrical components, it’s advisable to hire a professional to carry out the replacement.

3. Faulty Element

Convection ovens often have a separate heating element to assist with the convection function. If this element is faulty or burnt out, the oven might not heat properly during the convection cycle.

Solution: Check for visible signs of damage on the element. If it’s damaged or not glowing red when the oven is turned on, it’s likely faulty and will need to be replaced by a professional.

4. Incorrect Settings

Sometimes, the problem might be as simple as not using the correct settings. Each oven model has specific convection settings that need to be followed for optimal cooking results.

Solution: Ensure you’re using the correct settings as per your oven’s manual. If you’re not sure, check the user guide or consult with the manufacturer’s customer service.

5. Malfunctioning Thermostat or Temperature Sensor

A faulty thermostat or temperature sensor can affect the oven’s ability to reach and maintain the set temperature, which can impact the convection function.

Solution: You can check the accuracy of the thermostat with an oven thermometer. If there’s a significant discrepancy, you might need to replace or recalibrate the thermostat or temperature sensor. Again, a professional should handle this task.

Locate the resistor power supply trace. The wires can be connected to the electronic board or to the thermostat.

Select an ohmmeter or multimeter continuity function.

  • Without disconnecting the resistor, place one of the probes on the resistor terminals, and the other on its power terminals (on the electronic board or other element).
  • If you see OL or 1 , the connection is bad. It will have to be repaired.

In conclusion, while it can be frustrating when your oven’s convection function stops working, understanding the potential causes can help pinpoint the issue. By following the appropriate troubleshooting steps or enlisting professional help, you can restore your oven’s convection feature to its optimal performance. As always, safety should be your primary concern when dealing with appliances, so don’t hesitate to call in the experts when necessary.
