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.
