Oven no longer heats - troubleshooting


First, you have the creeping feeling that the frozen pizza takes a perceived eternity until it's done. The Sunday roast is rather chewy than crispy and you can still keep your hand in the oven even after extensive heating. The oven does not heat up properly. Maybe it's just a small thing that's fixed quickly.

Determine small errors

Some reasons for a poor heating of the stove you can already see with the naked eye. The oven often can not heat properly because the heating elements are dirty. Therefore, the oven should always be cleaned thoroughly as a first measure. This includes a check of the door hinges. If the door no longer closes completely, the heat can escape and the stove can no longer hold the heat inside. Then you can heat up the oven and check if the error is still present.

  • Basic cleaning of the oven
  • Check heating elements for stuck dirt
  • Check hinges for contamination
  • Clean the gasket around the door

Check seals

Also on the gasket around the door, some dirt may have settled, preventing the door from closing properly. Over time, however, the seal itself may be damaged or even missing. This damage should be corrected before you check the function of the stove again. Bear in mind that a gasket has also been placed around the pane of glass, which may become damaged over time.

Replace lighting

It may sound weird, but a faulty oven light can drain the energy. The oven can not heat up properly either. The cover of the lamp should also be intact. Likewise, you should search the glass of the door for rough cracks, because here too the heat can escape senseless.

Tips & Tricks

But you should not go to the electrical parts of the oven. You must not connect or disconnect the oven, nor repair the electrical system in the oven. This may only be a certified electrician. Independent electricians with small craft companies usually charge far less for the repair of the furnace than you fear.
