Cooker in home kitchen

With the COVID-19 (coronavirus) pandemic still ongoing and the UK government currently advising us to avoid unnecessary contact with other people, you may be hesitant to invite a tradesperson into your home right now. But if your oven has broken down, what choice do you have?

Well, actually, you may be able to resolve the problem yourself. There are plenty of useful resources available for self-isolating homeowners who want to fix their own cookers - for instance, a repairman living in the Algarve has recently been offering appliance repair advice via video chat, and naturally there are loads of 'how to fix it' blogs and YouTube videos on the World Wide Web.

And that's where we come in. Here at Cooker Spare Parts, we stock an enormous range of high-quality spares for gas, electric and dual fuel appliances, including:

  • Ovens

When preparing a family meal or showing off your culinary skills, the oven is one of the most frequently used appliances. Whether you have a gas or electric oven, we'll discuss what to do when you suffer from this issue.

Please note: we always recommend you use an electrical or gas-safe registered engineer to carry out repairs.

Signs You Have A Problem

Is your oven taking longer than it should to cook your meals? Have you been following all cooking instructions to the letter - selecting the right temperature and leaving your food in for exactly as long as you're told - only to find that, when you open the door, everything is still lukewarm and half-raw?

If so, the problem may be that your oven isn't getting hot enough. Just because you're turning the knob to 200°C, doesn't mean that the oven is actually reaching that temperature.

If you're constantly having to pop your dinner back in for another few minutes just to get it cooked properly, there's probably a problem with your appliance that needs to be addressed.

Common Causes

Now that you've discovered the first signs your oven is not heating up correctly, it's time to find the cause of the problem. Here is our recommended checklist for electric and gas ovens:

  1. Defective electric oven thermostat.
  2. Faulty electric oven element.
  3. Broken gas oven thermostat.
  4. Damaged gas oven burner or ignition electrode.

You'll Need

Once you've found the culprit, you'll need to find the correct replacement part. For this you'll need the following:

  • Model and serial number - this will be found on the data badge on the cooker/oven.
  • Owner's manual (optional).

Defective Electric Oven Thermostat

If you notice that your electric oven isn't heating up to the correct temperature and food comes out under-cooked, this many be caused by a defective electric oven thermostat.

Thermostats measure the temperature inside the oven cavity, switching the electric element on and off to maintain the desired temperature.

The Fix

Firstly, check that the temperature sensor isn't touching the oven walls, as this will affect the accuracy of the internal temperature readings. If it is, reposition so it isn't touching the wall and see if this helps.

If you're still suffering with the same issue, you'll most likely need to replace the whole thermostat. Luckily these are inexpensive parts that are around £10-£30.

Faulty Electric Oven Element

Is your oven not heating up at all, no matter which temperature you select? For fan ovens specifically, you may notice that cold air is being blown into the oven cavity. This is a sign that your electric oven element is faulty.

Electric oven elements are the part that generates heat and often glows red when it is switched on. If you find that your element is deformed, bulging or blown, it is time to find a replacement.

The Fix

There is an easy solution to this problem, you'll need to replace the complete element. Fortunately, these are around £8-£30.

Broken Gas Thermostat

Similar to electric appliances, gas ovens also have thermostats that maintain a constant oven temperature by adjusting the size of the flame on the burner accordingly.

If your food is always under-cooked, you may need a replacement thermostat.

The Fix

Before purchasing a replacement thermostat, make sure you check that the temperature sensor isn't touching the inside oven wall. Simply adjust the position and test to see if this has fixed the problem.

Still not working properly? Then you'll need to replace the entire gas thermostat. Thankfully we supply a wide range of parts that start from just £25.

Simply give our team a call on 02920 452 510, or email us on with your appliance model and serial number. Alternatively, input your details into the search bar above.

Damaged Gas Oven Burner or Ignition Electrode

For the more serious issue of your gas oven not heating up at all, you may have a damaged oven burner or ignition electrode.

When you set a temperature on the oven, you should hear clicks followed by the sound of gas igniting.

The Fix

If you don't hear the gas igniting and the clicking stops, you'll probably need to replace the ignition electrode. Luckily these are just £5-£20.

Should the issue continue, you may have a damaged oven burner. This can be a complex problem, so we would recommend you find a gas-safe registered engineer to take a look at your appliance.

SAFETY FIRST! Before attempting any electric oven repairs, be sure to switch off and unplug the appliance. Never work on an electrical appliance that is still connected to the mains. If in doubt, don't risk damaging your oven and/or harming yourself - call in a professional.

Oven element

Problem: The oven is not heating up because the element (the bit that actually gets hot when you switch the oven on) isn't working.
Solution: This electric oven repair is fairly common, to fix it order a new oven element for your appliance and use this to replace the faulty element.


Problem: Your oven's thermostat - which measures the heat inside the oven and switches off the element once the desired temperate has been reached - is not working properly. As a result, your oven is not getting hot enough, getting too hot, or failing to heat up at all.
Solution: Purchase a replacement thermostat for your electric oven and replace the one that isn't working.

Terminal block

Problem: Your appliance is plugged in and switched on at the wall, but no electricity is reaching the oven and it won't turn on at all.
Solution: You may need to replace your cooker's terminal block so that electricity can reach the appliance itself.

Oven fan

Problem: The fan inside your electric fan oven is not functioning properly. As a result, your food is cooking unevenly (this happens because the heat is not being distributed evenly around the oven by the fan).
Solution: Buy a new oven fan assembly and replace the faulty parts as necessary.

Oven door seal

Problem: Your oven is losing heat because the rubber door seal is broken or missing. As a result, the oven takes longer to heat up and uses more energy than necessary.
Solution: Order a new oven door seal and fit to the door.

Bottom Oven Not Working

It's great having a cooker with two ovens: not only does it give you more space for big dinners, it also allows you to cook at two different temperatures simultaneously. If your top oven has a grill function, you can even grill one thing while oven baking another!

Of course, the downside of having another oven is having another thing that can break down. Sometimes the entire appliance will malfunction, putting both of your ovens out of action, but it's more common for just one of them to fail - not so totally disastrous, but still very frustrating when it happens.

Today, we'd like to focus on the bottom oven; if yours has stopped working, you may find the solution you seek below.

From here on out, we'll specifically be referring to ELECTRIC ovens. If your GAS oven has broken down, please see our previous troubleshooting post - My Gas Oven Won't Light.

Common Causes

There isn't just one reason your bottom oven might stop working, but luckily this checklist will let you check for the most common faults.

  • Power supply
  • Electric oven element or thermostat

Please note: we always recommend you use a qualified electrical engineer to diagnose and perform the repair to your appliance.

What You'll Need

Once you've found the defective cooker part, you'll need the following to find the correct replacement for your appliance.

  • Model and serial number - this information will be found on a data badge on the appliance.
  • Owner's manual (optional).

For further assistance, feel free to call our team on 02920 452 510, email us on, or use the search bar above with your model and serial number.

What to Do

Unfortunately there isn't a simple one answer fix to why your bottom oven may have stopped working. However, there are a few quick checks you can do to ensure a smooth repair.

Plugged In

Make sure it's plugged in. First of all, ensure that the appliance is plugged in properly and switched on at the wall.

Power Supply

Find out if any electricity is actually reaching the appliance. If the cooker isn't doing anything at all - if the clock is off, the lights aren't coming on, and neither the hobs nor the ovens are warming up.

The most likely problem is that no power is actually reaching the appliance.

Assuming that everything is plugged in and switched on, this is probably due to a faulty power supply - it might be that the plug itself is damaged, or that the cable is defective.

Alternatively, you may find that there's a loose connection at the rear of your cooker.

Buy Electrical Fittings

Electric Oven Element or Thermostat

Replace the broken part. If you've performed the three checks listed above and found everything to be A-OK, it's probable that one or more of the parts in your bottom oven need to be replaced. 

The most likely culprit is the oven element - that is, the part of the oven that actually heats up - but simply replacing this may not be enough to ensure that the problem doesn't happen again.

You need to ask why the oven element failed in the first place; for example, it could be that your thermostat broke, and your oven element overheated and failed as a result of this.

Zanussi Replacement Elements

If your Zanussi cooker is no longer heating up, it may be because you need to replace the oven element. Fortunately, this task is nowhere near as difficult as you might expect, and even if you've never attempted to repair a cooker before, you're probably more than capable of getting it done. Read on for expert advice from the Cooker Spare Parts team - your trusty Zanussi appliance will be up and running again before you know it!

How to Order a Zanussi Oven Element:

It's very easy to find and purchase the right element for your Zanussi oven here at Cooker Spare parts, but first, you'll need to find out your cooker's model number (e.g. ZOB551X). This information can be found on the data badge, which is usually located behind the oven door on Zanussi appliances.

Once you've written down the model number, head over to the Cooker Spare Parts homepage, enter your manufacturer and model number, and click 'Search Parts'. We will then show you a full list of the parts that are compatible with your cooker.

Alternatively, if you already know exactly which element you need, you can head straight to our Zanussi oven elements page and simply select the one you wish to purchase. Either way, our secure and straightforward online checkout system will allow you to place your order in just a few clicks.

How to Install Your New Zanussi Oven Element:

Once your new element has arrived, replacing your broken element is a fairly simple task. The exact method may vary depending on which Zanussi cooker you own, but here's a rough guide on how to replace your Zanussi oven element:

  • Ensure that your cooker is switched off at the wall.

  • Open the oven door, remove the shelves, and take off the panel at the back of the oven to access the space where the element is housed. You may need to unscrew the panel with a screwdriver before you can remove it.

  • The broken element should be held in with screws, so pick up your screwdriver again and take these out so that you can remove it.

  • You will also need to gently pull the wires out of the broken element - be sure to take a photo beforehand in case you forget which wire goes where!

  • Take your new element and connect the wires that you just removed from the old one (refer to the photograph you took if you can't remember where each one goes).

  • Screw the element back into place, then screw the back panel on and put your oven shelves back in.

  • Dispose of the broken element (preferably by recycling it).
