For cooking appliances, wall ovens offer the most options.
The features can seem endless, from unique controls and convection systems to steam integration and smart functionality.
But what happens when your high-tech, expensive oven fails right before a major holiday?
Repair is a huge problem in this industry, even for basic washers. Service will be the most challenging for wall ovens.
In this article, you’ll learn which wall ovens are the most reliable, based on over 33,000 service calls logged by our department just last year.
Let’s get started.

Let’s face it: figuring out which brands are truly reliable isn’t easy.
Consumer Reports is one option, but their tests are done in a lab (not a bad idea).
They also rely on surveys (a very bad idea) to determine reliability.
Most other information you find? Likely a guess - because 98% of appliance dealers don’t offer service, and even fewer employ more than a handful of techs.
Here’s what you need to know:
Key takeaway: Look for reliable brands and reliable service. Don’t forget to Google reviews on service in your area.
Our 40 service technicians handle an average of 8–10 calls per day.
We calculate appliance reliability by dividing the number of products we serviced by the number of products we sold over a 12-month period.
Each service visit is recorded as a service call.
Some people have asked for a longer reliability history. Honestly, I’d like that too.
However, we provide free service during the first year, so we assume most customers will use us during that time.
Beyond the first year, it’s difficult to track accurately - especially as homes are sold and ownership changes.
You can expect some variation in repair trends from year to year.
This year seems more ominous.
The increase in repair needs may be due to supply chain expansion and working with various parts manufacturers. Only time will tell if this is the case.
The following service rates are calculated from over 1,000 products sold and serviced within a 12-month period, with a minimum of 40 units sold per brand.
These rates reflect how often each brand required service during the first year of ownership, giving you a clear picture of reliability.
Wall Oven Service Rates by Brand: 2025 Reliability Data
| Service Rates | |
| Gaggenau | 0% |
| Café Appliances | 3.4% |
| Miele | 5.3% |
| Bosch | 6.5% |
| LG Studio | 10.4% |
| Monogram | 11.1% |
| Thermador | 13.3% |
| GE Profile | 16.3% |
| Grand Total | 9.5% |
Now, let’s look at the top-performing brands to understand what sets them apart and how their features might match your cooking style.
Previous Service Rate: 2.1%
Gaggenau consistently ranks in the top three for built-in wall ovens.
It's French-made and German-engineered, but more importantly, we didn’t service a single Gaggenau wall oven in 2024.
That’s pretty impressive.
Previous Service Rate: 4.7%
I thought this was interesting. Café is way more reliable than the lower, yet similar GE Profile.
It's the same company.
Most Café ovens purchased at Yale are French door wall ovens. A side-swing or French door wall oven allows for easier access to food.
Unlike in a traditional fold-down door, you don't have to lift heavy items over the door.
The display is full color and lets you know the ideal internal temperature
Café wall ovens are unique because they are available in stainless, black, or white and have six handles.
Plus, if you’re wondering how your food looks while it’s cooking, Café's wall ovens have a built-in camera.
GE is one of the last companies to have a service department, although it recently changed its name to Bodewell.
So, a Café wall oven is a great consideration if you buy from a store without service.
You probably will because 95% of the stores do not have service departments.
Previous Service Rate: 3.9%
Miele is an excellent wall oven.
It’s highly reliable because Miele manufactures almost all its parts, including controls, in their single German factory.
Most other manufacturers outsource many of their parts and assemble the units elsewhere.
That’s why you often see similar clocks on different ranges when shopping at your local appliance store.
Note: Miele is currently in the process of building a factory for ovens in the US.
As for features. everyone talks about smart technology, but “smart” doesn’t always mean easy - or even useful.
Miele wall ovens are different. Their technology is designed with simplicity and functionality in mind.
For example, the MasterChef controls are some of the easiest to use in any wall oven. Just input the food and how you want it cooked, and the oven automatically sets the recommended time and temperature.
Want to make sourdough bread or cook lamb to medium-well? Simply press a button and let the oven handle the rest.
Miele also offers a steam assist feature with up to three bursts of steam. The benefits of steam are many:
Lastly, like Café Appliances, there’s a built-in camera. You can monitor your dish from the Miele app on your phone without opening the oven door and losing heat.
Previous Service Rate: 11.6%
Bosch has long been known for its reliability across almost every cooking category.
Their ovens have kept the same product design over the years, with a contemporary look that fits flush in your kitchen.
They offer plenty of space with 9.2 cubic feet of cooking capacity and a True Convection system.
Full-extension racks make it easy to load and unload heavy dishes like roasts and casseroles.
These ovens offer 12 specialized cooking modes, a temperature probe, and a fast preheat function to save time.
Plus, automatic convection conversion and pre-programmed settings take the guesswork out of meal prep.
Previous Service Rate: 4.4%
LG Studio appliances are incredibly popular because they offer excellent features at a lower price point.
Unlike Bosch, the LG Studio wall oven is a completely new design.
This double oven provides 9.4 cubic feet of cooking space, features convection cooking and 14 cooking modes, and is priced at $2,499.
This is significantly less than the $4,000-$8,000 range of comparable models.
It even includes an InstaView door: tap it twice to see inside or darken the glass.
One great option is their double wall oven with a speed oven on top and a steam oven on the bottom.
A speed oven combines a microwave and convection oven, allowing you to cook faster without the rubbery texture associated with microwaves.
The steam oven is user-friendly, although it doesn’t offer the advanced controls found in Miele ovens. Then again, LG Studio is about $5,000 less expensive.
LG Studio wall ovens are known for their reliability and functionality, as LG manufactures more of its own parts than any other major appliance brand.
However, LG’s customer service has been less reliable in the past, though they now have their own service department to address issues.
Wall ovens need repair about 9.5% of the time within the first year, which is the same as the average of 9% for appliances overall.
Interestingly, I would have expected wall ovens to need far more service than the average appliance.
Many wall ovens are sold as double ovens, meaning a higher likelihood of servicing two units instead of just one, compared to a dishwasher or cooktop.
Additionally, wall ovens tend to have more installation and education issues than other appliances, which can contribute to service needs.
Here are the top three issues customers experience with wall ovens, based on service data:
Knowing these common problems can help you anticipate potential repair needs, but how long should you expect a wall oven to last before replacement becomes necessary?
The life expectancy of wall ovens is often overstated by manufacturers, with some claiming up to 20 years without substantiated evidence.
According to the American Servicers Association, the average appliance will last 6-10 years.
Wall ovens, however, tend to fall on the higher end of this range. Unlike ranges, for example, they don't rely on ignitors or elements, which are prone to wear and tear.
But what happens when repairs are needed?
Knowing when to repair or replace your wall oven can save you time and money.
If your wall oven is experiencing issues, here’s a simple rule to help decide between repair and replacement.
Our service manager recommends replacing your wall oven if repair costs exceed 30–35% of the oven's original price.
You should also consider the installation cost, which will be between $250 and $500, depending on whether you need to cut the cabinet and/or change the power.
Wall ovens have always been challenging to repair, and with advanced controls, they’ve become even more complicated. That's why finding a reliable service company is paramount.
As technology is becoming more complex, service needs are increasing, and reliable support is harder to find.
If you add up all the service rates for cooktops, refrigerators, dishwashers, and wall ovens, you will need service on at least one appliance within two to three years.
Service has to be part of your buying process. Check reviews of every warranty service agent.
Smart features like Alexa compatibility are cool, but ultimately, having a working wall oven when you need it most - like before Thanksgiving - is far more important.
