5 Common Causes That Will Make A Neff Oven Not To Heat Up

Before you pick up the phone to call a repairer, it’s worth taking a closer look at some of the common causes that could be behind your oven’s malfunction. From a faulty heating element to a broken thermostat, let’s have a look at the five common causes that will make a Neff oven not heat up.

  1. Damage to heating element
  2. Issues with the fan
  3. Faulty thermostat
  4. Fault seal on the oven door
  5. Faulty igniter

Damage to The Heating Element 

An element correctly functioning will appear bright red. If damaged, it will stay dark grey, the same color when cool. Most experts do not advise trying to handle this repair alone. Instead, it is advisable to call the professionals to ensure no additional damage occurs to your Neff oven. 

How To Fix

However, if you want to have a look at the problem yourself, below are the steps you’ll need to follow:

  1. Locate the heating element in the oven.
  2. Turn the oven on.
  3. Without touching, see if the element turns bright red.
  4. Monitor the temperature inside the oven.
  5. Purchase the right replacement part.
  6. Install (or hire someone to install) the new heating element.

Issues with The Fan

Neff ovens use a special kind of technology that is not found in any other oven available today. This technology pulls air from the oven through a powerful stainless-steel fan. It then circulates the hot air around the oven, cooking food more evenly and quickly than traditional ovens.

This helps you save time and energy since minimal preheating is needed. However, if you start to notice issues with the fan, it could be a sign that there is a problem with your Neff oven, and it will need fixing.

How To Fix

  1. Locate the fan
  2. Inspect electrical connections
  3. Ensure there is power coming to the oven to turn the fan on
  4. Replace the fan if needed.

Faulty Thermostat 

If the problem is the thermostat, the fan will still turn on; however, there will be no heat. The purpose of the safety thermostat is to ensure your oven does not overheat. If the temperature gets too high, it automatically turns the oven off. 

Additionally, if the thermostat is faulty, you will need to replace it to ensure your oven is functioning properly.

How To Fix

  1. Locate the thermostat
  2. Purchase a new thermostat for the make and model of your Neff oven.
  3. Remove the screws holding it in place.
  4. Replace with the new thermostat.
  5. Test the oven to ensure it heats up again.

Faulty Seal on the Oven Door 

On the oven door, there is a rubber seal inside that keeps heat in while foods are cooking. Over time, the rubber may become dry and cracked, resulting in the heat not staying in the oven and the temperature falling significantly. In fact, the oven may not even reach the desired temperature at all. A faulty seal may also cause the oven to become extremely hot on the outside, which can be potentially dangerous.

To fix a faulty seal on your oven door, you will need to follow these steps:

How to Fix It

  1. Inspect the door seal carefully for cracks, missing pieces, or dryness (all these issues can cause heat to escape your oven)
  2. Remove the old rubber seal.
  3. Replace it with an oven-safe adhesive.

Important Note: Avoid using the oven until the adhesive has fully cured when replacing the rubber seal. 

Faulty Igniter

The igniter is responsible for igniting the gas in a gas oven. If it’s faulty, your oven won’t heat up properly or may not even heat up at all. A faulty igniter may also cause the oven to produce a gas smell, which can be very dangerous.

To fix a faulty igniter on your oven, you will need to follow these steps:

How to Fix It

  1. Turn off the gas supply to your oven
  2. Remove the oven racks and the bottom panel to access the igniter
  3. Disconnect the wires from the faulty igniter
  4. Remove the screws holding the igniter in place and take it out
  5. Replace the faulty igniter with a new one and secure it with screws
  6. Reconnect the wires to the new igniter
  7. Carefully put back the bottom panel and oven racks

Turn the gas supply back on and test the oven to ensure it heats up properly.
