Does the Plastic Dome on NuWave Ovens Crack From Heat?

Megan Mattingly-Arthur

The NuWave Pro is a countertop oven manufactured by Hearthware, Inc. NuWave ovens combine infrared, convection and conduction technology for fast, even cooking. They also feature a clear plastic dome that allows you to watch the food as it cooks.

Although the dome is designed to withstand the oven's heat, improper care may weaken the plastic and cause it to crack. Learning how to correctly use, clean and store the dome helps prevent cracking and other damage.

Assembly and Dome Use

Assembling the oven components incorrectly or on an unstable surface puts unwanted stress on the dome. To assemble the NuWave, put the liner pan and cooking rack inside the oven base. The liner pan handles must be in the dropped down position for the dome to fit onto the base properly. Set the power head unit on top of the dome and turn the handles clockwise to lock it into place. When using the oven, lift the dome by the handles on the power head.


The manufacturer recommends washing the dome in warm, soapy water before the first use and after each subsequent use. Always wait for the dome to cool completely before cleaning it. You may wash the dome by hand or in the dishwasher. Don't use abrasive cleaners or the dishwasher's heated dry setting, both of which can damage the plastic. Allow the NuWave dome to air dry or dry it with a soft towel.


The NuWave comes with a wire dome holder that attaches to the oven base. You may put the dome and power head assembly on the holder when moving food in or out of the oven. However, the manufacturer cautions owners against storing the dome on the holder for long periods of time. To prevent damage to the dome, store the oven completely assembled.


If the plastic dome on the NuWave oven does crack, you can replace it. NuWave ovens come with a one-year limited warranty that covers the dome and other components against manufacturer defects. Contact NuWave customer support to see if you're eligible to receive a complimentary replacement. Even if the damage to the dome isn't covered under the terms of the warranty, you may order a replacement oven dome from the NuWave website.
