There are several reasons why an oven does not heat up. To properly diagnose the cause of the failure and find the appropriate solution, proceed step-by-step and perform a series of tests first at the power supply and then at the oven itself.
Test the oven power
When an oven is not heating up, first make sure it is not a power problem. For this, simply try to turn on the lamp inside the oven (if it has this function).
Check the oven resistances
If the light comes on, select a heating mode for the oven (here in a rotating heat) and allow it to warm up for a few minutes.
Then turn off the oven and put your hand inside to check that it is heating well.
It is imperative to test all the proposed cooking methods: hearth heat, grill, natural convection, etc. A little time should be allowed between each test, as the oven must have cooled to be able to know the exact cause of the failure.
Check the hearth and vault resistances if the oven does not heat up in natural convection.
Heat of sole
Replace the hearth heater (located at the bottom) if the oven is not heating in hearth heat.
Replace the vault heater (top) if the oven is not heating up.
Replace the circular resistance (in the oven) if the oven is not heating in rotating heat.
Check the operation of the propeller
If the resistors are in good condition, it must be checked that the propeller of the oven is well screwed. To do this, locate the location of the screws of the bottom plate and undo.
To reach the propeller, remove the bottom plate from the oven.
The propeller must turn freely. To function normally, it must be well secured. There must be no game.
When this check is complete and the propeller is turning properly on its axis, replace the plate.
Screw in the bottom plate of the oven using a suitable screwdriver.
Test the oven motor
It remains now to test the motor and the oven fan.
