My Lamona oven continues to give me grief. After replacing the Inner Door Glass which seems to continually self-destruct, I went to heat up my dinner and now my oven doesn’t heat up! A quick search on the internet reveals a likely suspect for my newest problem, it seems it’s not so uncommon to have to replace the Oven Element. Or, at least, this does seem to be the most likely cause according to us DIY’ers who would rather fix than replace.
Apparently, a lot of Oven Elements can be replaced without removing the oven itself, most but not all. As yet I am not sure if mine is one of these ovens. Also, some suggest a good way to know if the element is faulty is that the Oven Lamp will come on but there will be no heat from the oven. It seems this is the best and cheapest place to begin as this is what my oven is doing and without wanting to spend money on expensive engineers, this will be my first step on my next oven repair.
Lamona Inner Oven Door Glass
It’s now been a few months since following up on the ever present problem of the spontaneously exploding Lamona Inner Oven Door Glass. There are quite a few of us who are the unlucky ones where half way through your Sunday roast cooking there is a sudden explosion in your oven, only to find that along with your roast chicken and potatoes that you have about a million pieces of glass that have also peppered your favourite meal. Feeling frustrated doesn’t really sum up how most people feel.
I’ve searched the web and it seems that it is mostly a select range of Lamona ovens where this happens. I’ve noticed through my research that this particular door glass is fitted to various different brand cookers like Beko, Belling, Diplomat, Flavel and so on. From reading your comments though it seems that Lamona ovens are the ones that are mostly affected. One has to wonder why? Were these the only ovens where the door glass if fitted by what appears to be 2 screws (one ether side) which seems to be the butt of the problem and are all the other ones OK?
It’s also been suggested that cleaning the inner door removes a heat resistant coating. Surely this can’t be true? A heat resistant coating that you can clean off seems like an absurd excuse for a self-exploding door glass. Also, I am sure that all of us who never cleaned the glass and then it also exploded would disagree that this is the answer to the question.
Also, there are other various models of Lamona ovens which have a Lamona Inner Door Glass like model numbers HJA3212, HJA3220 and HJA3320 which seem to be exempt for suddenly self-destructing, of course this particular door glass is specific to these models only and seem to only need replacing when the wife gets a little over enthusiastic with the cleaning and drops it.
I look forward to reading what you all have to say, please keep the comments coming as we are all interested.
We all get used to our freezers and go about our lives without thinking much of the days when a freezer was a luxury not a necessity. We only realise how important it is when it fails.
I had a look into most common problems occurring with our freezers and without any surprise to me it is freezer baskets, flaps and covers that are being treated poorly and fail quite often. Unfortunately at the top of the list are freezer flaps and freezer covers. These get damaged quite often and it is not uncommon for an engineer to see duct tape holding broken pieces and cracked flaps together inside your fridge or freezer.
Why do the freezer flaps and covers break?
It’s our fault. We try to squeeze too many items inside the drawers and our children seem to love to swing off them. At first it looks like we succeeded fitting all our food inside, however what we don’t realise is that food expands as soon as it starts to freeze. Ice crystals are slightly larger than the water which they were built from, therefore the frozen food will take much more room (especially those foods rich of water such as meat, fish and vegetables). Unfortunately these natural forces are gigantic. Freezing water can easily damage such strong materials like asphalt, pipes or concrete, therefore a plastic freezer flap will stand no chance with this force of nature and simply break.
Smashing a freezer door onto freezer flap or cover is second most common reason for flaps to break. We live our lives in hurry and often forget to close the freezer flap or leave freezer basket pulled out slightly. When the door smashes the flap or cover it simply breaks.
Freezer flap or cover?
A typical freezer will have both: flap and covers
- Top (fast freeze) flap. In most cases this is a fixed compartment with drop down or lift up flap.
- Freezer draw cover. The cover that is fixed to the front of the freezer drawer. This usually can be found on lower freezer baskets.
All freezer flaps and covers come in variety of sizes with different fitting pins so it is very important to look for one specific for your freezer model. It is not uncommon that two different freezer flaps will look alike however the dimensions and fittings will be different. Please bear in mind that flaps and covers although look very similar have different fittings. Your freezer most likely will have one flap (on the top) and one or many draw covers.
Lamona (Howden) Freezer Flaps
If you have Lamona fridge freezer you will need to check your model number in order to find correct flap or cover. Typical Lamona model number begins with HJA followed by 4 digit code. Please make sure you take model number from the appliance itself not the corresponding manual as these are often printed for several models. Few examples below:
I have written about the exploding inner oven glass for Lamona ovens many times before. This is quick follow up on my enquiry in to the matter:
Recently Howdens (supplier of Lamona appliances) started to tell affected customers that the reason behind the breaking glass is the way the customer treats the oven. Apparently cleaning the oven with some heavy-duty cleaners may remove the heatproof layer from the inner door glass – at least that’s what Howdens has been telling some of its customers.
I didn’t buy that and continued with my private investigation. I have managed to gather following facts.
- The inner oven glass we talk about is manufactured by Beko and fits around 160 oven models of various makes: Beko, Belling, Flavel, Lamona and others.
- The same glass fits only 11* models of Lamona (Howden) models. That’s about 6.8% of all ovens that the glass has been fitted to.
- From the survey conducted amongst customers whom ordered replacement inner glasses approximately 98% where those who had Lamona ovens (we have asked for a model number and 98% of them begun with HJA, which is Lamona code).
It seems that the very same glass explodes in only 6.8% of these particular ovens. In other words: mere 6.8% of ovens are responsible of 98% of accidents. Coincidence? Not a chance.
It seems like it’s easier (definitely cheaper) to blame customers for a glass that explodes spontaneously rather than take the full responsibility for the faulty design. But which one is it? I guess the right question to ask is what causes 98% of accidents in mere 6.8% ovens. Why other makes are not affected?
The simplest answer is the design of the oven itself.
The Devil is in the Design:
Lamona (Howden) 11* models.
Inner door glass is fitted by two screws on each side. The problem with this fitting has been described in here>>
Beko 106* models.
Inner door glass is hold by a frame and locked by locking mechanism on upper side of the door.
It seems that different fitting used by Beko solves the problem of exploding oven glass.
Should you need to replace your oven glass (guess you are one of unlucky Lamona Howden customers) please contact manufacturer first. If your oven is less than 12 months old you should be able to get free replacement under your warranty. Don’t let them tell you that it’s your fault. We have heard from many customers whom complained that Howdens would try to blame you for the fault. Let them know that you are aware of this common problem and they probably will eventually replace the glass for you for free.
Unfortunately if your oven is more than 12 months old you will have to take care of replacing glass by yourself. Please take a special care when fitting the glass in particular not to screw the glass to tight as it may contribute to future glass failure.

A grill pan is a type of oven pan (usually with a raised wire grill grid), used for cooking under the grill element of the cooker. Grill pans come in variety of shapes and sizes and are not an integrated part of the oven (this means that original part can easily be replaced or subsidised by compatible or universal part).
Above we present the standard Lamona Grill Pan to fit the following Lamona cookers: HJA3240, HJA3400, HJA3700, HJA4610, HJA3242, HJA3650, HJA4600, HJA4620, HJA3300, HJA3660
It is a standard metal tray that measures approximately: 395mm x 340mm. The grill pan does not come with the grid and handle, as these are listed as separate parts. In order to gather the complete assembly you will need following items:
For those who would rather not spend a small fortune in order to replace whole set I would recommend a universal grill pan assembly. This product consists of pan, wire grid and a handle. Approximate measurements are 380mm x 280mm so it will easily fit Lamona and various other brands ovens. It’s an effective and most definitely cheaper way of replacing the Grill Pan.
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…?
I have written about the Lamona (Howden) inner door glass once before. It seems like the problem of the inner door glass shattering is greater than I originally thought, therefore I have decided to investigate the matter thoroughly.
My research proves that the reason behind the shattered glass is a design flaw. It seems to me like the two fitting screws on each side of the glass put enormous pressure on the glass during cooking. During the cooking cycle heat of up 250C force the glass and screws to expand and then shrink back again to it’s original size when the oven cools down. However glass and metal don’t expand and shrink in the same way (this is down to the physic properties known as Thermal Expansion). The process creates huge forces (Mechanics: Stress) between glass and screws. Unfortunately glass is not as “flexible” as metal screws, therefore when the stress reaches a critical point glass simply explodes in order to release accumulated energy.
I have conducted a survey amongst customers who had their Lamona oven glass shatter, and here are some key facts:
1. The average lifespan of the oven glass seems to be about 9-12 months
2. It appears that there are more chances that your oven glass will explode if you tamper with the fixing, i.e. you unscrew the glass in order to clean it and then screw it back again.
Lamona appliances are made by numerous manufacturers therefore the same glass is not used in all Lamona ovens. Here’s the list of affected models that we know of:
HJA3200, HJA3242, HJA3310, HJA4600, HJA3202, HJA3300, HJA3313, HJA4610, HJA3240, HJA3303, HJA3650
