The other day, my son heard a cracking sound when he opened the oven door, and it wouldn’t close properly anymore. It seems that the oven door hinges spring wasn’t working to hold the weight of the door and when closed, the door would sit ajar.
On further inspection, the pin that would connect to the springs was broken, so there was no choice except to remove the door from the oven so that I could have a better look at the problem. Fortunately the manual showed how to remove the door, which in this case was very easy, lift it, and then pull outwards while tilting back towards the oven. If the springs were working, we would have to normally open the door, then engage the hinge latch which would allow the door hinge to stay in the open position for the door to be removed.
I found that the part number was GN166667 and after a quick check on eBay found a supplier that had a pair of these original hinges for around AU$64 after an eBay discount was applied. If I order this from the spare parts warehouse, I would be paying AU$55 plus delivery for each hinge, so I ordered from eBay and saved a bit of money.
On my Kleenmaid oven door, there are two screws that hold the inner door from the outer glass door. Also around the top and sides of the inner door is a sealant that has also deteriorated. I found by at Bunnings, a Sika 300g Black Sikaseal Appliance Sealant for AU$14.78 that has a high temperature resistance, up to 250°C which appears to be the right sealant for the job.
Next step was scraping off as much of the old sealant as I could – a razor blade would have been handy, but who has one of these nowadays with electric shavers.
A few days after I had ordered the hinges, they arrived. The hinges are held to the inner door by three screws, two on the base, and one screw that is at the top of the hinge, only accessible when the inner door has been separated from the outer door.
The inner door, by the way had two sheets of glass – one that is facing the inside of the oven. This means that the door assembly has three sheets of glass, so good insulation of preventing the heat from radiating through the door.
Here is a picture of the two hinges after removing from the door. The top one should not be able to stay like that since the spring should be pulling back, except of course it is broken. From recollection, a while ago, the door didn’t seem to be closing properly which could mean that one hinge had already failed at that time. Also I didn’t find any broken bits of the pin, so no idea how it broke unless it had just kept wearing away, due to the door being opened and eventually there was not much left of it. The oven is 12 years old – and I have worked on this in the past, with various electrical issues, but this was the first mechanical issue.
After the replacement hinges were installed, I then applied the sealant – it was difficult to squeeze the trigger and move the tip at the same time, to get the sealant into a good straight line with the correct thickness. Of course, if I did this over and over again, like the appliance repairers do, I could then do a good job each time, but for my first, I did an adequate job. Once the sealant was on, the inner door was mounted and screwed up.
I did have a bit of sealant squeeze out, so used a cloth to wipe around the edge of the inner door, and got most of the excess sealant off and cleaned up well enough. The sealant generally takes 24 hours to cure, so it was left in the garage to do this (also the sealant smells, and wife doesn’t take kindly to stinky things in the kitchen).
The next day, I wipe the door over, since the garage is dusty – then needed to extend the hinges and lock them in the open position. I used an adjustable spanner, to hold the tip of the hinge, then cranked it open – then moved the latch, and released the hinge. Both hinges were done eventually. I did slip with the spanner a couple of times, without breaking my fingers, but one was a little sore afterwards.
This picture shows the door removal and installation process – showing the movable lock that I call the latch.
Then it was a matter of getting the hinges into the slots in the oven frame, then letting it settle downwards and latch, then open the door fully, release the latches then the door can close – actually they closed very well – looked better than new, no gaps at all.
Now I have most of a tube of appliance sealant left over, who needs some? By the way, if I got an appliance repairer to do this job, I wouldn’t need the sealant since they would have it, but it would cost AU$250 for the callout, and then plus parts and whatever additional labour is needed – so likely to be around AU$400 or so, but this has cost me AU$75 to do it myself. There it is – another repair done, and the wife is happy!
