There are a number of faults that can a Zanussi oven might stop heating up properly.
The most common causes of this issue include:
- Broken fan oven element or fan motor
- Faulty thermostat
- Clock or timer not set
- Tripped fuse board
- Issues with the power connection
If you’re having issues with the heating element of your Zanussi fan oven, you don’t need to run out and immediately buy a replacement!
The first thing you should do is identify the reason why your oven is no longer heating up so you can repair the faulty components and fix the problem in one job.
This guide will cover the most common reasons why Zanussi fan ovens fail to heat.

Broken Heating Element
Multiple oven elements inside a Zanussi cooker are responsible for heating the inner compartment of the appliance.
If just one of these is faulty, it can disrupt the heating mechanism of the oven.
You can identify whether a faulty element is the root cause of your issue by looking at the following things:
- The oven clock and timer are set properly (whether you did this manually or automatically).
- The oven’s light turns on when you start cooking and remains on until the oven has reached the desired temperature.
- The oven fan motor is working adequately, and you can hear it spinning.
If all of the above seems okay, it’s likely that one of the elements inside your Zanussi appliance (whether it’s the fan oven element or the grill element) is faulty or broken.
Checking the Condition of Your Zanussi Oven Elements
To check the condition of the oven elements, you’ll need to follow these steps:
- Open the oven door to access the inner compartment
- Find the two electrical connectors
- Connect a multimeter that is set to a low resistance to each electrical connector
- Measure and note down the reading on the multimeter
The reading should be anywhere between 20 and 100 ohms. If you get no reading at all, it indicates that the connection is dead, and the elements aren’t working properly. You’ll need to repair faulty elements or replace them altogether.
Replacing a faulty heating element in any Zanussi oven model is a relatively simple task. It shouldn’t take too long, and you may be able to do it yourself without any struggles.
If you’ve checked the oven elements and they’re all healthy, but your oven still isn’t heating adequately, the issue could lie with the thermostat.
First, check that the temperature indicator light is working.
Checking the Temperature Indicator Light
You’ll find the temperature indicator light or thermostat light on the control panel of your appliance, and it will turn on when you switch your oven on to begin cooking. The light will go dark when the cooker reaches the selected temperature.
If the temperature indicator light doesn’t come on at all, it’s a sign of a faulty thermostat. In this case, you’ll need to replace the thermostat inside your Zanussi oven to restore its function.
Clock or Timer Not Set Correctly
Surprisingly, something as simple as the clock on your Zanussi oven not being set properly can disrupt the appliance’s function.
If you’ve recently had a power cut in your home, you’ll need to reset the clock in order for your appliance to work efficiently.
Luckily, resetting the clock on your oven is quick and easy. You can find instructions on how to do this in the manufacturer’s user manual.
Clock Not Working Properly
If you try resetting the clock in your oven but the time won’t adjust, or if the display isn’t visible at all, this can also cause your oven to failt to heat. The timer can switch off if the fuse board has blown or the electrical circuit is loose.
You’ll need to identify whether the issue is with the clock, the display screen, or the electrical wiring inside your appliance to fix the problem.
You should always disconnect the live, neutral, and earth electrical wires before looking at the electrical supply or replacing faulty circuits to reduce the risk of electric shock.
