The easiest way to find out who to call is to refer to your literature that came with your appliance. It will direct you to the closest agency and will list contacts and phone numbers. Calling your equipment dealer is another way if your literature is not available. As of late a lot of manufacturers will list these contacts on their web sites under support or agencies. Also check the appliance itself for tags or labels that will direct you.
Recovery is a term used to quantify the performance of an appliance.
It is usually applied to fryers. It is determined simply by measuring the time it takes for a fryer to raise the temperature from 275 degrees to 325 degrees. Most manufacturers publish standard recovery rates for their fryers. Some fryers equipped with modern electronics will automatically check this for you every time you start up. This can vary from oven to oven.
