Cooker or Oven Not Heating Up

If you are finding your cooker is not getting hot you have come to the right place for help and support. Learn how to repair and fix your oven with our step-by-step guides and helpful videos.

We will tell you the possible reason for why your oven is not working, and what specific parts could be the cause of the problem. All your burning questions can soon be answered!

Cause 1

Clock Not Set

Recently been plunged into darkness? It’s bad enough having to change the time on your oven clock twice a year, but if you’ve had a power cut it will probably need setting again.

A clock that’s not set can cause your whole oven to stop working - crazy, but true. This is a very easy fix though, so it’s the first thing to check if you’re having oven problems.

Just dig out your manual or download a PDF version of it right here on our site to find out how to set the time on your make and model of oven.

With our help, you will hopefully soon be back to being able to create your delicious meals again!

Cause 2


If the clock is set correctly, the element is fine and there’s still no heat from your oven (in other words, if you went to check on your pizza and the melted cheesy goodness you had your heart set on is still frozen) there could be an issue with the thermostat.

You need to first of all check to see if the temperature indicator light is working:

  • This is the small light on the front of your oven that remains lit until your oven reaches the desired temperature.
  • If this light does not illuminate at all this may be a sign of a faulty thermostat and sign of a replacement.

With the help of eSpares, you can replace the thermostat to get your problem sorted.

Cause 3

Thermal Cut Out

It appears that you have come to this article because it is safe to assume that you have been faced with a faulty cooker or oven.

If you have checked to see that your appliances' clock is set correctly, the element is working, but there is still no heat in the oven!

A microwave meal could be on the cards if you can’t get to the bottom of this dilemma. Taking to the internet to find the culprit may be the only cost-effective solution to your woes.

If everything seems to be fine then it is time to test the thermal cut out, this little device automatically cuts your oven off if it gets too warm - so to avoid overheating. 

Here’s how to see if it’s faulty:

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Identify the two connections where electricity enters and exits the thermal cut out component.
  • Grab your multimeter again and switch it to a low resistance setting (you can see here for instruction on How To Use A Multimeter)
  • Measure across the connections. There should be the same amount of resistance there like you’d read if the two-meter probes were touched together.
  • Getting a different reading? We’re sorry to say then that your thermal cut out has failed - and needs replacing.

It is not all bad news though...the good news is that you can soon get a replacement right here on the eSpares site!

Cause 4

Terminal Block

Another part that can cause an oven to breakdown is the terminal block. The symptoms that suggest an issue with the terminal block include:

  • A clock that’s not displaying.
  • Areas of the cooker that aren’t working.

If the terminal block is to blame, you’ll find your culprit at the back of the appliance where there may be a number of circuits connected by links from the main power connection.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • If any link or connector is loose it can result in heat and damage.
  • Look for signs of charring or loose connections.

If you do find damage there is no need for you to panic about it, as eSpares could soon help you get the problem sorted.

If you require a replacement, see our range of oven spares where we have an excellent selection of terminal blocks

Cause 5

Clock Not Working

Time is of the essence and if your oven clock is not working that's not going to help you to create your tasty meals at dinner time!

If there is no power on any of the cooker’s circuits:

  • Check the fuse board and power supply before suspecting a problem with the cooker itself.

If the clock is still not working or is showing a hand symbol meaning you can’t set it properly, then this means that unfortunately it has failed and will need replacing.

This, however, is not the end of the world - you can soon get a replacement clock from the eSpares website, as we offer an extensive range of cooker related spares.

Not only that, you can also see our helpful guide below on how to fit a new timer, so you can soon get the tick-tock back in your clock!

Cause 6

Heating Element

Another common cause of oven woes is a faulty element. If the below statements are true, you can suspect the element as the reason your oven is stone cold dead.

  • Your oven clock is working and set to manual not automatic.
  • The light on the front - that remains on until the oven reaches the adequate temperature.
  • You can hear the oven fan working as usual.

If everything seems fine, then look to your element as the cause of the issue.

You’ll need a multimeter to test it. If we have already confused you with what a multimeter is and how to use it, look no further and click here for our handy multimeter guide.

To check your oven heating element:

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Identify the two connections where the electricity flows through the part.
  • Use a multimeter on a low resistance setting and pop one probe on each of the connections.
  • Measure the reading; there should typically be a resistance between 20 and 100 ohms.
  • If there is no connection, then the element receives an F as it has failed the test - and it will need replacing.

It is not all bad news though, as we can help you out. You can find your replacement heater element today from our extensive range of oven spares on the eSpares website.
