Display Panel

The design of the control panel for this 1800 Watt induction cooktop makes this unit easy to operate. The controls from left to right on the display panel are:

  • Heat
  • Temperature
  • Timer
  • Plus/minus to set the desired temperature or wattage
  • On/Off

The display panel shows the mode (Temp or Heat), the temperature, and the time remaining if the Timer function is activated. The temperature can be displayed in either Celsius or Fahrenheit.

Housing and Dimensions

The stainless steel housing on this single burner induction cooktop from Waring is one of the features that sets it apart from many other portable induction cookers. The unit dimensions are 16"x13"x4".  The ceramic glass cooking surface is approximately 11"x11".

Easy-Touch Controls

This user-friendly cooktop has easy-touch controls used to adjust the heat, temperature, set a timer, and power the unit on and off with a single touch.

Temp/Power Modes

This unit is designed to use either the TEMP mode or the HEAT (power) mode.

The TEMP mode allows one to choose the temperature preset to use while cooking. The 12 preset temperature settings (displays can show either C or F) in Fahrenheit are: 120, 140, 160, 180, 210, 250, 280, 320, 380, 420, 460, and 500. Only the preset temperatures can be used.

The power range is 200-1800W. The 10 preset power settings (per Waring Telephone Customer Service) are: 200W, 350W, 500W, 650W, 800W, 1000W, 1200W, 1400W, 1600W, and 1800W. 

10-Hour Timer

The timer can be set up to 10 hrs. However, it is important to note that the unit will NOT automatically shut off. It will start to countdown when it reaches 59 seconds. When the time expires, the unit beeps four times, and the screen blinks. 


This Waring Induction Range is ETL (it is compliant with North American Safety standards) and NSF approved (met specific public health and safety standards set by NSF International.

The Waring WIH400 has an impressive complement of safety features.

After an extended time, the unit will shut off if there is an empty pan on top of the cooker. 

It will also shut off if there is no cookware on the cooktop or if the cooking vessel is not induction compatible.

If the cooktop overheats in the TEMP mode, the unit will shut off.

An error message will also be displayed if the unit's temperature is too hot, if the overheat protection sensor is activated or if the voltage is too high or too low.

Another useful feature that keeps the unit safe while plugged in is the small pan detection. This helps determine if there is something lightweight on the surface, causing the range to shut off, so it doesn’t cause a fire.

Final Thoughts

Whether you’ve never used an induction cooktop or if you’ve owned one for years, the Waring Commercial WIH400 Hi-Power Induction Burner gives a range of temperature and power settings as well as stainless steel housing and several safety features.  

Its small and compact design helps it to fit in any kitchen, regardless of size, and you’ll certainly appreciate having an additional burner at your disposal for personal or family meals.

Cookware to Use

Induction ready cookware must be used on this cooktop. Cast iron, enameled cast iron, steel, and magnetic stainless steel are examples of induction compatible materials.

The size of the glass cooking surface is 11" x 11".  The optimum size of the cooking vessel's base should be 4.75" to 10" in diameter.


The ceramic surface should be cleaned after each use. After the unit has cooled, wipe the surface with a damp cloth and dry with a soft cloth. Never use abrasive sponges or cleaners. White vinegar can be used to wipe away hard water spots. If you use vinegar, be sure to wipe the residue off with a damp cloth and dry with a soft cloth or paper towel.

Stainless steel can be cleaned with white vinegar or soap and water. Afterward, remove the residue with a damp cloth and wipe dry. Some people place a small amount of mineral or olive oil on a soft cloth and polish their stainless steel housing. When cleaning stainless steel, be sure to rub the cloth in the direction of the grain.


The Duxtop P961LS Commercial Portable Induction Cooktop is an alternative to the Waring WIH400. It also can be used in both commercial and residential kitchens and has stainless steel housing.

The Duxtop P961LS has additional power and temperature levels, a child lock, and a one-touch boil and keep warm settings. Here is a quick comparison table of the two models.
