Condensation in microwave / combi oven door and between the glass panels

Last updated 31/08/2021 10:05

Issue

  • Condensation / water / moisture gathers inside the appliance, inside the door and between the glass panels

Applies to

  • Microwave oven
  • Combination microwave oven

Resolution

The moisture leaves the microwave/compact oven through ventilation ducts, including the door.   This means that stains and condensation can form between the two glass panels in the door. The stains are caused by grease particles reacting with the cooling air.

1.   For models without a turntable, turn the dish midway through cooking, this is beneficial for even cooking and will release some of the vapour. This is particularly useful if the food has a long cooking time. 

2. Cover the food with pierced cling film or a loose-fitting plastic lid, this helps the cooking process, reduces splattering, speeds up cooking time and retains moisture in the food.   Moisture is released when food is heated up in an oven, especially in the case of frozen items. 

3. Moisture left in the cavity and behind the door glass is a normal part of the cooking process.  For best results, after use wipe with a clean dry cloth and leave the door ajar to further help the drying process. 

4. Moisture between the panes of glass, within the door can occur if the cavity has been exposed to a lot of water vapour, such as cooking for an extended period of time. The door can not be removed and panes of glass replaced. In most cases, this will evaporate. 

5. For safety reasons, the door cannot be detached, which means that it cannot be cleaned. Doors on microwaves and combination microwave ovens should only be removed by an authorised repair technician. 

6. In extreme cases, we recommend requesting a visit by a repair technician. Contact our team to book a repair.

Cause

  • Microwaves cook by agitating water molecules, thereby producing steam. Cooking this way is extremely healthy and safe but does produce water vapour. The process generates varying amounts of condensation, depending on the type of food heated up and the set temperature.
  • This is perfectly normal but may lead to a build-up of condensation inside the appliance.
