SYMPTOM Localised 'scorch' marks on the oven cavity faceplate and/or the door sub-assembly
following normal operation.
Variation in the sealing gap between the door sub-assembly sealer plate and oven
cavity faceplate could lead to localised scorching. This phenomenon can be
aggravated by abnormal usage such as no-load operation.
Suggested repair methods are as follows: -
1. Stainless Steel Cavities
Providing the scorching is not of a severe nature: -
Rub the cavity faceplate down to remove marks. This can be achieved by
