Sub-Zero Wolf Induction Cooktop Problems: 7 Common Issues (Must Know)

Sub-Zero Induction cooktops will make your life easier by allowing you to cook your food faster and more efficiently than ever before.

However, at times, your Sub-Zero induction cooktop can run into issues that can limit its functionality.

But there’s nothing to worry about, as you may be able to solve these issues by reading below.

Sub-Zero Induction Cooktop Not Turning On

A working induction cooktop should turn on with a simple button press.

Sub-Zero induction cooktop not turning on is most likely due to child lock mode being activated, problems with the power supply, or problems with the control board or coils beneath the glass.

To resolve the problem, read the solutions provided below.

Possible solution(s):

  • The first step is to check Sub-Zero induction cooktop “child lock” mode is not turned on. Unsure how to turn it off, check out the following link. 
  • Next step is to ensure there’s a constant supply of power to the cooktop. To do so, check if the power socket works and the cord is not damaged. 
  • Can you see any power lights or LEDs lit on the cooktop to see if the power is getting there? If there aren’t any, a fuse inside the cooktop may have blown, possibly due to a malfunction.

Plug it out Turn the appliance over, take off any electronics covers, turn on a bright light, and carefully inspect any wiring or circuit boards for blackened (charcoal) marks. It has failed if there are any, and the item that failed could be the blackened part or any other.

  • If the lights are on but the burners are not heating up, there could be a problem with the copper coils under the glass, which when they come into contact with the cookware, produce an electric current and heat.

You must take off the cooktop’s glass surface to check the condition of your burner. Typically, to do this, clamping brackets must be removed along with the mounting screws. You can lift the glass top once these components are out of the way. Place it aside on a stable, flat surface. Check out the wiring and copper coils now.

Are the copper coils showing signs of damage, such as clear scorch marks? If so, you’ll have to swap them out. Fortunately, ordering replacement parts online is simple.

The new models can simply be attached after the wire harnesses and spring clips holding the coils in place have been removed. Additionally, since replacement parts might not come with spring clips, you might need to reuse and reattach them.

If the Sub-Zero induction still won’t turn on, it is advised to contact a certified professional.

Be careful not to void any warranties before you begin to open up your induction cooktop.

Sub-Zero Induction Cooktop Not Heating Up Enough

If your Sub-Zero induction cooktop turns on but fails to warm up and cook your food properly, you may be facing incompatible cookware or an incorrect heating temperature. 

Follow the solutions below to understand what’s wrong with your appliance and how to fix it.

Possible solution(s):

  • A common reason behind this issue is incompatible cookware. If you use cookware that isn’t magnetic, the appliance will not be able to heat your food.
  • Incorrect positioning can also result in low heating. Try to place your pan in the dedicated area for heating marked on the cooktop.
  • If your cooktop fails to work even after following the solutions above, there may be an internal issue that requires a professional to be fixed.
  • Make sure the “child lock” mode on the Sub-Zero induction cooktop is not activated. If you’re not sure how to turn it off, click this link.

Sub-Zero Induction Cooktop Making Noise

If your Sub-Zero Induction Cooktop is making humming, hissing, or buzzing noises, the source is most likely not the induction cooktop but rather your cookware.

Compared to multi-ply stainless steel pans and pots, heavy cast iron skillets and Dutch ovens are less likely to make noise.

Slight noise is acceptable for appliances such as an induction cooktop.

However, if your Sub-Zero induction cooktop is making loud noises, it shouldn’t be ignored as it can indicate an internal fault.

Follow the solutions below to fix the issue.

Possible solution(s):

  • To keep things, cool inside, induction cooktops have a fan installed. If the cooktop starts to make noise, it’s likely due to debris between the fan blades or a faulty motor. Hire a professional to fix the fans.
  • Uneven cookware can also result in noise, as the magnetic field can make it vibrate if you notice your cookware vibrating or moving while cooking, replace it with a pan with an even surface.

Sub-Zero Induction Cooktop Lights Flashing

Typically, LEDs flashing on the control board of an induction cooktop aren’t a serious issue.

However, if they continue to flash, then there may be something wrong.

Here are some solutions to fix the problem.

Possible solution(s):

  • One of the possible reasons for the flashing of lights is that you simply left your cooktop on after using it. Turn off the cooktop and check if the lights are still flashing.
  • If the solution above does not work, try shutting off the cooktop from the main power switch and turning it back on.

If the Sub-Zero induction light still flashes, contact a certified professional to take a look.

Sub-Zero Induction Cooktop Control Panel Not Responding

If you try to turn on your cooktop through its control panel or change its modes, and the control panel appears to be unresponsive, you are likely to be faced with a faulty control board. 

Here are some solutions to this problem.

Possible solution(s):

  • If you’re lucky, the control panel may be unresponsive simply due to being locked. Locate the lock button on the cooktop and press it for about 10 seconds to unlock the panel.
  • If the lock button fix doesn’t work, you will need to replace the control board as it has issues with its hardwiring.

Sub-Zero Induction Cooktop Overheating

Sub-Zero Induction cooktop overheating is likely to be caused by incorrect temperature settings or incorrect cookware being used. 

If your food comes out to be burnt and you don’t recall placing it on the cooktop for a longer than usual period, it’s likely there’s something wrong with your cookware.

Lightweight cookware has a tendency to heat up more quickly than usual, increasing the chance of food burning.

The solutions mentioned below will help you in fixing the issue.

Possible solution(s):

  • First off, check your cookware. If you are using cookware that’s lightweight, getting your food burnt is an easy possibility.
  • If you are using the recommended cookware, make sure you are following the temperature guidelines as well.

Sub-Zero Induction Cooktop Keeps Turning Off

Sub-Zero induction cooktop burners turn off or power down by themselves to prevent overheating, which is caused by excessive use.

Possible Solution/s:


  • If the cooktop is installed above an oven, it may shut down if both appliances are heavily used. Allow the oven to cool before testing the cooktop operation.
  • If the cooktop functions properly after cooling, it is performing its intended function of protecting components from excessive heat.

Cookware Not Touching Surface

  • Induction Cooktops detect when cookware is removed and automatically turn off. Make certain that the cookware remains in contact with the cooking surface.

If these steps do not resolve the issue, contact your local service center

Sub-Zero Induction Keeps Tripping 

If your Sub-Zero induction cooktop keeps tripping, the problem is most likely a faulty cable between the tripper and the socket.

Replace the cable yourself or have an electrician do it for you.

Everything should be fine. If the cable is fine, the problem is with the induction cooktop; perhaps the main cable connecting the cooktop is faulty.

Sub-Zero Induction Cooktop Glasses Damaged

Sub-Zero induction cooktop glasses scratched or cracked will need to be replaced.

An induction cooktop that has been cracked or shattered cannot be repaired. It needs to be replaced.

Possible solution(s):

  • The first step in replacing the cooktop is to turn off the breaker outside that supplies power to the cooktop. Then, in the cabinet beneath the cooktop, follow the flex power cord to the wall. Remove the cover plate from the wall-mounted box.
  • Disconnect the wires from the wall wires. Next, check the bottom of the cooktop for any clamps that hold the cooktop to the countertop.
  • If there is one, remove it. Then simply lift the cooktop off the counter. Simply reverse the steps to install the new one.
