Shattered Lamona Oven Glass

I have written about the oven glass for Lamona and Beko cookers that explodes spontaneously before. Here is a brief reminder of the problem:

In a late 2010 it came to my attention that a significant number of oven glasses for Lamona (Howden) and Beko cookers have been replaced by customers. Sales of that particular spare part increased sharply towards the end of 2010 and through 2011. I have conducted a survey amongst customers as well as looked into the design of the oven door glass itself.

Two major things stand out:

  • unusual fitting of the oven glass itself (it’s attached by a single screw on each of the sides);
  • and secondly the vast majority of customers said that they cleaned the oven glass just before the glass shattered;

Many of the engineers I have talked to focused on the first point: the attachment of the glass. It seemed like there was a major design flaw: The screws that hold the glass on each side must put an enormous amount of pressure on the glass during the cooking cycle (thermal expanding and shrinking).  The manufacturer rejected that as the reason and claimed that design of the oven was not at the source of the countless oven inner glass explosions.

A recent follow up on the case and statements taken from customers who have replaced oven glass and complained to the manufacturer suggest that the problem rests in the heat-proof-layer of the glass and that its being removed (or damaged) when cleaning the oven. This would be in line with the survey I have conducted amongst people who were affected by the problem, as a majority of them did mention that oven glass was cleaned just prior the incident. It seems like the manufacture’s answer to the problem may be to leave your oven door dirty…?

    Finally they acknowledge the problem. Any chance for free replacement?
