The Waring Commercial WIH400 Induction Cooktop can be used in a commercial business or residential kitchen. This 120Volt,1800Watt cooktop has a stainless steel housing and a nice size ceramic-glass cooking zone. This NSF and ETL-approved commercial induction cooktop is robust and easy to use.

Waring WIH400 Features

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.

This unit uses either the TEMP or 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. 

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. The unit beeps four times when the time expires, and the screen blinks.

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.
  • The unit will shut off if the cooktop overheats in the TEMP mode.
  • An error message will also be displayed if the unit's temperature is too hot, the overheat protection sensor is activated, or 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 something is lightweight on the surface, causing the range to shut off so it doesn’t cause a fire.
  • What We Like About the Waring Commercial WIH400?

    The Waring Commercial WIH400 Induction Cooktop is a portable cooktop that can prepare foods from different cuisines in a residential or commercial kitchen. Food can be prepared using temperature or heat (power) mode.

    It is safe and energy-efficient, offers exhaust and flame-free, with just a few buttons, and has a 10-hour timer.

    Since there is minimal heat around the cooking surface, no heat is created in the cooking area. This is a bonus in the summertime since the kitchen won't get hot while you are cooking. The unit cools quickly after you have turned it off.

    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. In addition, The 11"x11" Schott(R) ceramic glass cooking surface is a big plus.

    The Waring WIH400 display panel has the basic functions which make food preparation simple. The timer and heat settings can be adjusted by increasing and decreasing buttons throughout the cooking process.

    The various heating levels allow you to use many cooking methods. You can steam, sear, saute, fry, boil, or simmer. Be sure to have your ingredients ready as the unit heats up quickly.

    When using the temperature mode, you can select the temperature to be displayed in either Celsius or Fahrenheit.

    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. Many of the cheaper units are not ETL, or NSF approved.

    What is Not Ideal

    The Waring WIH400 comes with a one-year warranty, while many Duxtop units have a two-year warranty.

    This unit does not have a settings lock. This increases the chances of the settings being changed accidentally.

    As previously mentioned, the unit does not automatically shut off when time has expired.

    The cord is four feet long; a five-foot cord would be helpful.

    How to Use the Waring WIH400


    After plugging the unit into a 120V/15amp electrical outlet, place the induction ready cookware (base diameter must be 4.75” to 10”) on the glass/ceramic cooking surface and press the ON/OFF button.

    Tip: If the cookware is not induction suitable, four dashes (----) will appear along with the word “STANDBY.”


    Select a cooking mode by pressing either the HEAT or TEMP button.

    To adjust the wattage or temperature, press the + and – buttons. In the TEMP mode, you can select either Celsius or Fahrenheit.

    Timer Function

    Once you have selected the HEAT or TEMP mode, the timer can be set. Press the TIMER button and use the + or – buttons to adjust the time from one minute to ten hours to set your desired cooking time.

    When the time has been counted down to “0”, the unit will beep four times, and the screen will blink.

    The timer will not automatically shut off once time has expired.

    Final Tasks

    When you are finished cooking, remove the pan from the cooking surface. Then press the ON/OFF button. The fan will continue to run for a minute or so until the cooktop cools down.

    Wait for the fan to stop running and for the unit to be either warm or cool before starting the cleaning process.

    The glass/ceramic plate can be cleaned with a damp cloth and a mild soapy solution. Do not use cold water on a hot cooking surface. For more details, please read our article on cleaning an induction cooktop.
