CONVENTIONAL vs. CONVECTION – oven comparison


If you are in the market for a new oven, there are two types that you can choose from conventional or convection. Consider the pros and cons before investing your money. Knowing and assessing the differences between the two will help you make the right choice that will work best for your needs and budget.

Heat Source

So what’s the difference (CONVENTIONAL vs. CONVECTION) ? Technically, all ovens cook by convection, where the hot interior air does the cooking. Standard or conventional ovens use natural convection and radiant heat to cook food. The burners heat the air inside the oven and transfer the heat to the surface of the food. With convection ovens, an insulating layer of air that is cooler than the overall interior of the oven surrounds the food. Convection ovens have an additional heating element and an extra motorized fan, which blows heated air throughout, diminishing the cooler air next to the food. A convection oven has upper, lower and back heating sources.

Internal Temperature

Regulating the internal temperature is easier with convection ovens because the fan circulates the hot air continuously. The third heating element located near or around the fan in the back of the oven heats the air to a uniform temperature before it enters the oven cavity. The balanced heat circulation prevents hot spots. Conventional ovens tend to have hot spots. Food on the bottom rack tends to overcook or burn because it is close to the heat source. In similar fashion, placing food near the top of the oven often overcooks it because it is close to the upper heat element. Furthermore, the rising heat tends to accumulate at the top. Placing food near the center of the oven will yield better cooking results.

Cooking Time

Foods cook much faster in convection ovens. Convection cooking speeds up the chemical reactions of food during cooking. Baked goods release steam quicker, roasted meats render fats sooner and sugars in vegetables caramelize faster. A convection oven cooks food 25 percent faster than a conventional oven.

Cooking Quality

Convection ovens cook food more evenly compared to conventional ovens. Meats cook faster with more juice retained inside. Convection ovens cook meats with deeper flavors, crispier edges and are tenderer inside. In some cases, cooking with conventional ovens can result in drier meats, with a burnt outer part and not cooked well inside. Convection ovens can cook different foods evenly in different pans on different racks at the same time without transferring tastes, while conventional ovens cannot.


Conventional ovens come in two types — range and deck. A range oven, also known as the general-purpose oven, is a part of a cooking system. It usually has a stove on top and an oven at the bottom. Some models may come with an incorporated microwave or convection oven at the center. A range oven may use electric or gas heat source. Deck ovens save space. They can be freestanding or built-in. Deck ovens may use electric or gas heat source. You can choose from single, double or triple deck ovens. Convection ovens may come in a range or deck along conventional ovens to allow cooking preferences. There are also portable or countertop convection ovens that you can buy if you have a conventional oven but would like to use a convection oven to cook small amounts of food.


Most convection ovens are pricier than conventional ovens; however, consumers find they quickly recoup the higher initial cost from the energy savings achieved with faster cooking time.

The problem with any remodel is that within a few years it may have already gone out of style. This is especially true in kitchens, where the newest fashion trends seem to come and go on a whim. One minute wood paneling is the hottest stuff on the market and then a few years later it looks dated and out of place. But in many kitchens, it’s actually the household appliances that age quickest. Remember when pea-green and avocado were hip and chic. Remember when the biggest refrigerator or microwave meant the best quality of product. Trends always change over time, so when remodeling a kitchen the best design philosophy is to stay as neutral as possible. And installing state-of-the-art stainless steel appliances is the smartest way to stay stylish and to keep it that way.

The Stainless Steel Solution
In today’s modern kitchen, stainless steel appliances are treasured investments. If you own them, you’re proud of them. If you don’t have them, you want them. Why? Well, they’re sleek and simple, yet still look tough and durable. Also, their elegance can come in any shape or size. From can openers to stoves, microwaves to refrigerators, this material can be found on any kitchen utensil. Plus, just turn on the TV and you’ll see a million shows where professional cooks attempt to turn everybody into a gourmet chef. Therefore, many homeowners want to imitate the look of these shows as well. Stainless steel appliances help to replicate the look of real restaurant kitchens, giving an authority to any amateur cook by making the room itself feel luxurious and special. And unlike other trends, this is doesn’t look to be a fad. Since they’ve always been considered high-end products, they’ve always been in style and this fact won’t change anytime soon.

The New Neutral
Though stainless steel appliances add a more contemporary, industrial appearance to a home, they can also blend in with any pre-existing décor. White surfaces were once thought to be the ultimate neutralizer: since it’s actually the absence of color, everything else can match it. However, the same can be said for metal: its naturally reflective material allows it to echo the look of any surrounding material. It’s the best of both worlds. Due to their shine, they can really pop; but they can also fade into the background. Even if you don’t like the “industrial” look and prefer wooden cabinets, linoleum floors, and Formica countertops, metallic veneers can still fit in with any personal design choice.

Metallic Maladies
But like any other design choice, these products aren’t perfect. Here are some things to consider while making your decision.
Excessive Expense: They’re popular but not cheap, sometimes costing up to twice as much as standard models.
More Matching: Yes, they can fit it to any pre-existing décor, but they can’t stand alone. It looks strange to have a metal stove next to a black, plastic dishwasher. It’s always a good idea to match your machines. So when you buy one, you may have to buy more.
Tough but Tender: Though durable, they can be damaged. Scratches are always a problem but can be eventually be filled in with special products. Dents can also occur, though sometimes this can add to their authenticity.
Maintenance: They can easily smudge and fingerprint. So you’ll need to constantly clean them with hot, soapy water and occasionally apply a special polish to keep them shiny and looking new.

  1. Ask your friends for a referral. The very best way to find an Appliance Repair Service is by “Referral”. When someone you know recommends a company they were completely happy with(which includes service, price, professionalism, etc.)then you already know you’re getting a good company. Just be sure you trust this person’s opinion!
  2. Look for license and insurance. The ad you’re looking at should say “Licensed & Insured” and should have the company’s state license.
  3. Check to make sure their license number is valid and their insurance is current.
  4. Check the length of time the company has been in business at the same location, under the same name. A company with a long local history is a better bet than a recent startup with no history in the area.
  5. Look to see that they are in the major business internet directories.(,, google maps, yahoo local, etc.)
  6. Be aware that companies who spend a lot of money on advertising have to get that money from somewhere... usually in the higher fees they charge you.
  7. Weigh the benefits of the personal attention you will receive from a family-owned business vs the unknown technician a larger company will send. A local person has a reputation to uphold locally. A representative of a large national chain however, may or may not be concerned about giving you the best deals or service.
  8. Ask the name of the technician they are sending and ask to speak to him/her. It’s ok to ask them how long they’ve been repairing appliances and see if they will talk to you about your problem. If they are honest, they will discuss your problem with you. If you explain the symptoms you are experiencing with your appliance, they should be able to give you some possibilities of what type of repairs you may need. If they won’t talk to you about it, you should consider that a red flag.
  9. Ask a specific question. For example: “Hello, I have a Kenmore gas dryer that was working fine until today. It still runs fine but there is no heat at all. If all I needed was a new igniter replaced, which is part number 279311, how much would the total repair cost me? I understand that you may find other things wrong and the estimate you give me over the phone could change, but all I’m asking is how much would it cost me if all you had to do was replace the 279311 igniter?” If they won’t answer that question, it should be a red flag to you.

Is your oven not baking?

  • Bad bake ignitor. You can’t tell it’s bad by looking at it–you must measure amperage. Just because it glows orange, doesn’t mean it’s good. On round ignitors, look for a current draw of 2.6 to 2.8 amps. On flat ignitors, look for 3.2 to 3.6 amps. Insufficient current draw will not allow the gas valve to open. If unsure how to test, check this tech sheet.
  • Bad valve. If ignitor checks out OK, remove power from oven, pull the two wires off the valve and ohm test. Should read two to five ohms. If open, replace valve.
  • Pilot is out. Try reigniting pilot. If it goes out again, check 1) gas supply (out of gas, crimped line, etc.), 2) pilot orifice clogged or dirty.
  • Pilot flame not wrapping around thermocouple. Reposition the thermocouple bulb so the pilot flame wraps around it.
  • If pilot is spark ignited and you’re not getting spark to the pilot, replace the spark electrode, spark module, and the ignition wire. These parts are inexpensive enough that it’s not worth the trouble to just replace one, replace the entire ignition system as long as you’re in there.
  • If your broiler is not working check the above steps with the broiler instead of the oven

Is your oven not self-cleaning?

  • Self clean latch bent or misaligned. Inspect for proper alignment to make sure that latch is contacting the latch switch.
  • Defective Self clean latch switch. Run continuity check.
  • Bad function selector switch. Run continuity check on switch.

Is your gas oven not getting hot enough?

  • Sluggish ignitor. A good ignitor will fire the oven in less than three minutes. If it takes longer than this, the ignitor is starting to go. Measure ignitor current draw as described above. As the ignitor gets sluggish, it takes longer for it to fire the burner as the oven cycles on and off while the in use thus lowering operating temperature.
  • Oven door gasket ripped or torn.

Is your oven door stuck closed?

  • Defective ERC. Check for error code in display. If error code given, check against manufacturer’s code explanations in owner’s manual or tech data sheet inside oven control panel.
  • Misaligned self clean latch. Disassemble oven to manually free latch and realign or replace as needed.


What do you know about heating appliances?

Heating appliances convert electrical energy into heat, which is used to toast bread, warm coffee, dry hair, or perform other helpful tasks. This heat is developed by passing current through a special wire called an element. Since the element makes it difficult for electricity to pass through it, some of its energy turns into heat. The electricity uses so much of its energy to overcome the resistance of a toaster element, for instance, that it glows bright red, thus toasting the bread.

Common heating appliances covered in this article include toasters, toaster ovens, drip coffee makers, and percolator coffee makers. Heating appliances that work on the same principles include clothing irons; electric fry pans, woks, griddles, and waffle irons; convection ovens; deep fryers; slow cookers; food dehydrators; rice cookers; steam cookers; indoor grills; espresso and cappuccino machines; iced tea makers; and popcorn poppers. Once you’ve learned how to troubleshoot and repair the most popular heating appliances, it will be easy to repair any of them.
