How To Replace The Oven Door Glass

The inner door glass of this Ariston oven was glued in place at the factory. Unfortunately it had become partially unstuck and needed gluing back in place. To do this you nee a silicon glue which can withstand the 300ºC temperature of the oven and remain flexible to absorb the expansion and contraction of the metal door frame. I couldn't find this in my local hardware store so once again I had to buy online. Luckily there are various options available. I bought 3 tubes of glue from www.ovendoorglue.co.uk which came with a handy scraper and plastic gloves to protect your skin from the silicon glue.

We now remove the partially unstuck inner door glass from the door frame and thoroughly clean both parts with KH7 de-greaser. We scrape off the left over glue and any burnt on grease using a razor blade scraper before cleaning both parts again with the de-greaser.

Once both parts are thoroughly clean and grease-free we clean the glass and the metal where we are going to glue it to with alcohol. Lastly we wipe the surfaces which are going to be glued with the wipes provided with the glue. It is essential that both parts are absolutely clean and grease free otherwise the glue wont stick properly.

Te next step is to prepare ourselves to glue the glass back in place. We put newspaper on the kitchen table to protect it and the oven door on top. We then put the glass in place and use small strips of masking tape to mark where the glass goes. The strips of tape are both a guide for when we put the silicon glue on the frame and subsequently allow us to locate the glass correctly without having to move it and smear the glue around. We also do a dry run with the cam clamps to check that we are 100% ready before adding glue - this avoids nasty surprises when the glue is applied.

Apply a continuous bead of glue around the perimeter of the metal frame using the strips of masking tape as a guide.

NOTE: There is a 2mm lip around the edge of the metal frame. This means that it is essential that the bead of glue is deep enough to ensure that it comes into contact with the glass all the way round. We used 3 tubes of silicon glue.

Now we position the glass in the door and clamp it gently in place with 2 cam clamps (using plywood to spread the load evenly across the glass). It is important that you don't clamp it too tightly, the idea is to hold the glass in place as the glue dries, not to create "glue squeeze-out" or heaven forbid damage the glass!

We leave the glue to dry for 48 hours before un-clamping. Once the clamps are off we remove the strips of tape and check that the glass is glued in place correctly.
