Is it normal if water drips from the bottom of the door during normal cooking operations?

Cause of water dripping from the oven:

This is  normally caused by condensation within the oven cavity.Condensation is a perfectly natural phenomenon of any cooking process and is not indicative of a faulty oven and does not cause any hazard.

Factors leading to it:

The degree of condensation is governed by various factors but the main ones are:

● The type of food being cooked.

● The power output of the microwave oven.

● The size and shape of the oven cavity.

Rectification:

The size of the cavity in relation to the oven's output is also a contributory factor of condensation.Condensation can normally be kept to minimum by covering the food ( with microwaveble cling film) wherever practicable.Alternatively,we recommend the cavity be wiped immediately after each time to avoid rust formation.
