How Does an Oven Thermostat Work?

There are two main systems that control your oven temperature

  1. is the conventional type with a capillary tube attached which will be used in conjunction with a selector switch.
  2. The other is a pcb (printed circuit board) which uses an Ntc sensor in the oven to control the temperature via relays.

This tutorial will show you how to replace a cooker oven thermostat. the video will explain the 4 main types of electric oven, it will be the same principal for single or double ovens, they are the same on built-in cookers or free standing

Before doing any work on the appliance, disconnect it from the electric supply!

 

when looking to buy a new thermostat it is best practice to use your full model number of the id plate or the number written on the thermostat itself 

What is an Ntc sensor:

NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting devices. ... NTC oven sensors are typically used in a range from 50°C to 300°C.

What is an Oven Thermostat?

the thermostat is connected to a long, hollow copper tube that extends into the body of the oven. This tube senses the temperature of the oven by heating up and relaying that heat back to the thermostat. When the thermostat is informed that the oven has reached the desired temperature setting, it shuts off the heat source. When the temperature in the oven cools, the thermostat triggers the heat source, allowing the oven to reheat.

Typical types include makes like
