"How

There are many parts to your cooker, each with a different role to play, but your oven thermostat is one of the most important parts of all. Found in both gas and electric cookers, the thermostat is an electro-mechanical switch that's in charge of regulating the temperature of your oven - but how does a thermostat actually work?

How does a thermostat work?

An oven thermostat regulates the temperature inside an oven. The thermostat's temperature-sensitive probe measures the oven's warmth, switching the heat on and off as necessary to maintain the correct temperature.

While all thermostats fulfil more or less the same function, different appliances sometimes use different types of thermostat. How your oven thermostat works will likely depend on when your cooker was made.

How older thermostats work

In older ovens, the thermostat is connected to a long copper tube that extends into the main body of your oven. This copper tube reads the temperature of your oven by heating up and relaying this heat back to your thermostat. Once the tube has heated to the set temperature, your thermostat will cut off the the heat source. When the temperature in your oven starts to drop, the thermostat will reactivate your oven burner/element, heating up the oven once again. This cycle continues to repeat over and over again whilst your oven is in use, ensuring that the temperature stays constant.

How newer thermostats work

More modern thermostats are attached to a long probe that extends into your oven. The thermostat is wired to a control board that controls your cooker's components, including the oven's heat source (whether that's a gas burner or an electrical heating element). When the probe senses that your oven has reached the designated temperature, it'll send a signal to the thermostat, which then tells your circuit board to turn off the heating supply. If the probe senses that your oven's temperature has dropped, it'll send another signal to your control panel to ignite the heating source once again.

Need a new oven thermostat?

If you find that your oven's thermostat is not functioning properly, you should not hesitate to replace it, as it may be causing your meals to come out over- or under-cooked. Whatever age your cooker is, we're confident that you'll find a compatible replacement thermostat here at Cooker Spare Parts.

If you've purchased a new oven thermostat and you're unsure of how to fit to your new cooker, you may find this step-by-step guide helpful.

Oven Temperature Setting
 
Have you noticed that your electric oven isn't getting as hot as you need it to be? Is your food under-cooked even after the full recommended cooking period has elapsed? Does every meal you make 'needs a few more minutes' than expected?
 
If so, the root of the problem may be your oven's thermostat. If your oven thermostat is not reaching the set temperature it may be time to replace it, here's some information so you can work out if that is what is wrong: 
 

What does an oven thermostat do?

 
You can think of the thermostat as the supervisor of your electric oven.
 
On its own, the oven element (i.e. the part of your cooker that actually heats up) doesn't know how hot to get - it just starts heating up when you turn the appliance on. The thermostat's job is to know what temperature you've asked for, measure the heat in the oven, and tell the element to switch off once the required temperature has been reached.
 
Of course, when the element stops heating up, the oven will gradually begin to cool, and so the thermostat is also responsible for recognising when the temperature drops - at which point it will wake up the element again.
 

What can go wrong with the oven thermostat?

 
If the thermostat stops working entirely, then in theory the element will just continue to heat up indefinitely, getting hotter and hotter until it burns itself out.
 
However, if you're experiencing the issues we mentioned earlier - thermostat not reaching the set temperature, food taking too long to cook - it's likely that your thermostat has a rather different problem. A thermostat that is improperly calibrated may misread the temperature in the oven, deducing that it is warmer (or cooler) than it actually is.
 
Here's how that plays out in practice:
  • You set the oven to 220°C.

  • The oven element starts heating up.

  • Before the temperature in the oven reaches 220°C, the faulty thermostat mistakenly gets a 220°C reading and tells the oven element to switch off.

  • Your cooker tells you that it's finished preheating, so you pop your food in...

  • ...only to find at the end of the cooking period that your meal is only half-cooked because the actual temperature in the oven was lower than the temperature you set.

Can I fix this problem?

 
Depending on the type of cooker you own, If your oven thermostat is not reaching the set temperature it may be possible for you to recalibrate your oven thermostat by measuring the actual temperature in your oven manually (using an oven thermometer) and adjusting the thermostat as needed.

How to Replace Your Oven Thermostat

Your oven thermostat is very important; it is responsible for ensuring that your oven heats up to the set temperature and that it remains regulated at all times. That's why it's important to know how to replace your oven thermostat if you find it is no longer working.

If your cooker is overheating or isn't heating up sufficiently there could possibly be a problem with your thermostat. This is when you should look to purchase a replacement.

Here are the signs to look out for to confirm you need to replace your oven thermostat:

  • Temperature inside oven cavity seems to be far too hot

Now that you've purchased your oven thermostat, the next step is replacing it - but if you're not a cooker expert, this can be difficult. This is where Cooker Spare Parts comes in to help! Below, is an easy to follow step-by-step guide that will instruct you through the process of how to replace your oven thermostat.
 

Step-by-Step How to Replace Your Oven Thermostat

  1. Safety first! Please ensure that your cooker is switched off at the mains before you begin to replace your oven thermostat. 
  2. Next, locate the thermostat that is currently fitted to your cooker. The control of your oven thermostat is situated behind your control knob, and the capillary tube is situated at the top of your oven cavity.

  3. To get to the back of your cooker if you have a built-in oven, you'll need to remove it from its cavity. To do this, remove the fitting screws - located on the rim of your oven - and unplug the cables. Then you can lift it out of the cavity.

  4. The next step in how to replace your oven thermostat is to remove the oven door. To do this, move the latch on your hinge to the open position; close the door up, and then lift it out.

  5. Unclip the capillary tube. Now that you can access the inside of your oven, you can now remove the thermostat's capillary tube which is situated at the top, and back of your oven. To remove it, simply un-clip it, move it around and let it hang in your oven.

  6. Next, remove your back and top oven panels. These may be held together by Torx screws, so it may require you to have a Torx set.

  7. Remove the capillary tube. Now that you have access to the back of your oven, you'll be able to see the wire feeding from the top and around your oven, and into the oven cavity. Pull the capillary tube out of the oven cavity.

  8. Now, you need to remove the fixing bracket that is keeping the wire of the thermostat in place. This again requires Torx screws. 

  9.  It's now time to remove the control of your thermostat. Before removing anything, we strongly recommend you take note of how the wires fitted; so when you come to rewire your new thermostat, you can do it in the same way. 

  10. Take a photo of how it is wired. Once you have taken note of how it's wired, you can remove the clips and the control knob.

  11. Remove the screws that are holding the thermostat control in place. Then you can simply remove the thermostat from the control panel.

  12. Finally, to replace your oven thermostat, just do the opposite of what you have just done - fix it to your control panel; rewire it; feed the wire through and fit the capillary tube back into the oven cavity, and fix everything back together.

If you have a Hotpoint electric cooker and you're experiencing problems with the heating, the cause of your problem may be the thermostat. Thermostats are responsible for regulating the temperature in your cooker; when your oven element has reached the temperature you've specified, the thermostat will step in and tell the element to stop increasing the heat but if you're facing problems with your thermostat  your element will just continue warming up. 
This will cause your oven to overheat, burning your meals and possibly damaging the element itself. For this reason, it's vitally important to replace your thermostat as soon as possible if it's beginning to become faulty.
