Conventional ovens work on an electric element for cooking or a gas burner. In this type of oven, heat radiates up and pushes cold air down which can lead to uneven cooking or baking. However, this type of oven is very common and usually inbuilt in kitchens or come as part of the kitchen range.

(b) Convection oven

Convection ovens cook food a bit differently. There’s a fan at the back that forces air circulation throughout the oven, cooking food more evenly. This also results in quicker and consumes less power..

MICROWAVE OVEN FREQUENT PROBLEMS WITH SOLUTIONS :

Most people may not do anything to maintain a microwave oven. Many will go for 20 years or more without any noticeable decline in performance. But with these appliances, we can’t predict anything as they may go out of service any time..

  • Sometimes the cord and plug may get physical damage due to heat, especially from a combination microwave/convection oven or from other heat producing appliances. If there is evidence of overheating at the outlet itself, the outlet (and possibly the plug as well) need be replaced.
  • Sometimes unusual sounds come from inside the oven. While these appliances are not exactly quiet, grinding, squealing, scraping, or other noises – especially if they were not there when the oven was new – may indicate the need for some more extensive maintenance like belt replacement or motor lubrication. For attending these problems you can contact us in near future.
