This is a brand new range and the elements do not
Ranges/Ovens use 220-240 Volts of power instead of 110-120 for most appliances. This is because you are converting electricity to heat. And in that process, you waste a lot! Resistance is what causes the heat to build, the more resistance to the flow of electricity, the more heat is generated. I am thinking that you are not receiving the correct wattage and or amperage to this appliance. Could be a bad cord, a bad connection inside the stove, or only a small amount of voltage coming to the plug. You would need an electrician to determine if you have 220-240 volts and at least 40 amps at the outlet where the stove plugs into. Volts are the flow of electricity, and Amps are the strength, or pressure. Without the both, you have very dim lights, slow running electric motors, and inoperable appliances. If there is indeed 220-240 Volts and 30-40 Amps at the outlet where the stove plugs in, then there are problems with the wiring inside the stove, or the elements themselves. Possibly, but unlikely, it could be the control panel, but you state it's fairly new. Hmmmm, sounds like low voltage, low amperage, and time to investigate both the outlet and the stove. You need an electrician, or someone really familar with electrical. This is important. This is not a mild shock, and a tingle up the arm, if they don't know what they are about, the amperage and voltage could be deadly. Not for the untrained. Have them check the outlet for the stove, and then the stove itself. Simple checks, and you should find it very easily. And, if the outlet checks out okay, then I would return the stove to the seller, and demand a replacement, since you say it's NEW. It's gotta warranty. Let the store take care of it's problem. You got cooking to do! Hope this helps. And PLEASE, Be SAFE. Don't attempt to check this outlet if you are not qualified and expierenced with electrical matters. It can be deadly, and permanent. Like going from holding your garden hose and washing your car, to trying to control a 2" fire hose from a fire truck pushing 600 gallons of water a minute. Thats just an example, but the theory is similar. Lots more volume and lots more pressure! Only this pressure and volume can ruin the rest of your life. Be Safe. Be Aware. And Happy Cooking Soon!
