Do you need to replace an oven timer?

All ovens and cookers come with a part called a timer, which allows programming the appliance. More precisely, the timer of an oven works like a kind of alarm clock. It displays the time and also allows you to control and set the cooking time.

Timers usually have four different operating modes. 

In “semi-automatic” mode, the startup is done manually while the end part is pre-program.

For “fully automatic” operation, both the start and the end are pre-program. In other words, the start time and the cooking time are set in advance.

For “manual” operation, you must control the cooking time yourself by switching the oven on and off manually.

Finally, there is position “0”, in which the oven is not turn on, regardless of the switch or thermostat position.

Nowadays you will find almost only electronic timers with a digital display? An IC chip controls these clocks. The IC chips are also known as a control board or as a power board. 

It regulates the power supply of the heating elements depending on the selected program. Sometimes the timer needs to be replaced to ensure proper operation of the oven. 

The following problems indicate that the timer must be changed:

  • The timer flashes
  • Timer does not light anymore
  • The clock on the timer doesn’t display time
  • It is no longer possible to program a baking/cooking process or pyrolysis
