Oven Door Glass Break

Do you need your oven door repaired or replaced?

Stove Doctor is here to help!

The glass used in oven doors is made from a special heat resistant toughened or tempered glass but unfortunately on a regular basis we at Stove Doctor receive calls in regards to oven glass doors "exploding" or "shattering". 

Normally when this occurs people get a real fright as when the glass does fail it often does so with a bang and can be a somewhat a dramatic experience as the glass can be thrown over the floor in front of the oven. Yes it is somewhat scary and dangerous but the oven shouldn’t be replaced as a repair is a lot more affordable.

There can be a number of reasons and normally there is no adequate explanation as the evidence lies in a thousand tiny pieces. Over the years we have heard many explanations from the manufacturers.

  • Damp cloth – If placed on the oven door handle it can create a temperature differential as the glass expands with the heat. This makes the one small area cooler and in turn causing it to shatter.
  • Abrasions - attempted removal of the glass with scrapers or grit being picked up in cleaning cloths can cause abrasion of the glass which will create a weak point in the glass.
  • Flaw in the glass manufacture - Minor flaws on the surface allow stress to concentrate so the glass may break from an imperfection.  The lack of resistance to a break means the crack can grow until it is obvious.
  • Bumps – If the glass is bumped, especially the oven door handle, it can cause the glass to crack immediately or at a later time all depending on the amount of damage caused by the handle.

It is also vital that the oven is checked for other faults as thermostat failures can often lead to the problem, faulty door hinges or even a faulty door seal. Basically anything that can allow the temperature to become unstable will cause the glass to explode.

There are several layers of glass used on oven doors, but almost all will have two glass panels, one outer door and one inner door. In pyroletic or self-cleaning ovens there will be at least three oven glass panels as an additional one is required between the normal two so as the outer panel stay within the Australian / New Zealand Standards for external temperature during the cleaning cycle.

In most cases the oven door glass is glued into place using high heat resistant bonding glue which on occasions can fail over time. If the glue does fail it is a relatively simple repair process but one that should be done right away as further door damage can occur if left unrepaired.

If you need a new glass panel please ensure you have the model number handy as each glass panel is unique to a particular brand and model.
