To crush the toughest ice into thin fine snowflakes, Shark Ninja introduced 4 new 1500-watt models with a powerful 2-horsepower motor. These models come with multiple cups, blades, and accessories for all blending, mixing, and chopping tasks.
Now, if you want to make the tastiest smoothies within minutes, first, you need to know how to work a Ninja blender 1500 watts. Plus, it’s important to learn what to do if the blender suddenly stops working.
So, here we will discuss how to blend anything with a 1500-watt Ninja blender and what steps you can take if anything goes wrong. Let’s dive right in.
How to Assemble and Operate A 1500-Watt Ninja Blender?
The four 1500-watt Ninja blender models share the same features, except for the accessories. So, the operating process is pretty much the same for all of them. Let’s consider the model BL772 and see how you can get it to work.

Assembly
Step 1: Unbox the blender and thoroughly clean all the parts, except for the base motor, of course.
Step 2: Select a dry and flat surface to assemble the blender. Refer to the owner’s manual to know more details about the components.
Step 3: Now, take the lower part of the 72 oz pitcher and make a proper alignment with the base motor. You’ll see a ‘lock’ sign on the base. Keep rotating the pitcher until it fits snugly just over or slightly right to the lock sign.
Step 4: Take the 6-blade assembly and carefully place it inside the pitcher on the driver’s gear. When done properly, the shaft will stand still and upright.
Operation
Step 1: Fill the pitcher up to the highest marking line with your preferred ingredients. Connect the power cord to an outlet and turn on the power button on the base. It should turn red when you do so.
Step 2: Place the lid on top of the pitcher and align the two arrow signs on the lid and the pitcher handle. You’ll hear a click when the lid is fitted properly.
Step 3: 1500-watt Ninja blenders feature 4-speed settings, including-
- 1 for mixing
- 2 for blending
- 3 for chopping solid ice
- Pulse for crushing and consistent blending
Select one as per your needs.
Step 4: Once you’re done, turn off the blender by pressing the power button.
1500-Watt Ninja Blender Stopped Working? — Here’s How to Fix It
A 1500-watt Ninja kitchen blender might malfunction for a bunch of reasons. Some basic reasons like faulty switches, jammed blades, wiring issues, etc., are easy to fix.

However, it becomes more difficult if there are any internal problems inside the motor or switchboard. But you don’t have to worry at all as you’ll get all the solutions right here! Let’s jump in.
Is the Power Button Light Not Turning Off?
A blinking or turned-on power button light is a common issue and might cause the blender to not function.
Causes:
- The wrong alignment of the blender components is the main reason the power light might not turn off.
- Damaged micro-switches can also cause this problem. Try different cups to check if the machine works. If it does, it’s a sign of worn-out micro-switches.
- Shark Ninja has infused a unique security system to prevent the overloading of the blender. If you have overloaded the machine, it will stop working, and the power light will be turned on.
Solutions:
- Make sure you have assembled all the parts correctly. Follow our detailed guide to ensure correct alignment.
- If the problem is with the micro switches, the only way to fix them is to get a replacement. Instead, you can ditch the particular non-functional cup and continue with the other ones.
- Avoid exceeding the maximum load limit while stuffing the pitcher. If you already have, turn off the machine for 15 minutes and thoroughly clean it before re-plugging it.
Has the Motor Stopped Working?
When the motor stops, the blades might also not rotate properly. Check the power button and electric outlets before approaching.
Causes:
- Improper fitting of the pitcher lid or the pitcher itself creates this problem, thanks to the Shark Ninja safety features.
- The motor is overheated
- Damaged power cord
Solutions:
- First, disassemble the blender components. Follow the owner’s manual to know the correct ways of placing the pitcher and blender lid. Make sure everything is snugly fitted.
- If the motor is overheated, stop the machine right away. Unplug it from the outlet. Wait 15 minutes or more to let it cool down.
- Check the power cord for twists or tangles. See if the casing is worn out or damaged. If so, get a new power cord, and the motor will work just fine.
Blender Base Is Leaking or Not Fitting?
Too often, many users have difficulty fitting the base to the surface and the pitcher to the base. Eventually, it might lead to the leaking of food and liquid.
Causes:
- The suction feet don’t fit if the surface isn’t smooth, like wood, tile, and unpolished finishes.
- If any chunk of food or dirt is stuck on the base, the pitcher won’t be attached properly.
Solutions:
- Clean and thoroughly dry the suction feet before placing them on a smooth surface. Don’t use the blender if the surface is unsafe and doesn’t offer a good fit.
- Clean the base area and snugly attach the pitcher to the base. If it doesn’t work, replace the rubber gasket to ensure a good seal.
Ninja Blender 1500 Watts Not Turning On – How to Repair?
When the internal components of the blender are damaged, it might not work at all. Here’s how to work the Ninja blender by doing proper repairs-

Servicing the Switchboard
Right beneath the base’s control panel is a switchboard with several multispeed switches. If any of these switches become damaged, the motor won’t work.
Here’s how you can check and fix it-
Step 1: First, you have to disassemble the blender’s base. Turn the base upside down and use a screwdriver and a screw gun to remove all the screws holding the base.
Step 2: After removing the base plate, you can easily locate the switchboard. Visually inspect all the switches and related wires. If the wire is torn apart or the switch has blackened, it needs replacement.
Step 3: You can use a multi-tester to check the switches and terminals. If there’s any loose or torn wire, replace it or use a proper seal to fix it. In case any of the switches are damaged, remove and replace it. Usually, these switches and wires are incredibly cheap, costing only $1 or $2.
Replace the Capacitor
This component is placed right in the middle of the board. If it’s swollen or damaged, it needs immediate replacement. And here’s how you can do it-
Step 1: Check how the capacitor Is attached to the board. Mostly, the two pins on the capacitor are glued to the board. You’ll need a soldering iron to take it off.
Step 2: Take the iron and find the capacitor pins on the flip side of the board. Slowly detach the capacitor without overheating the surrounding board parts. When you’re done, carefully pull the capacitor and remove it.
Step 3: Before ordering a replacement, ensure the voltage and capacitance rating of the new capacitor are identical to the old one. Check the old capacitor to know these ratings.
Step 4: Now, check the board beside the capacitor holes for negative and positive markings. Take the new capacitor and insert the negative pin into the negative hole and the positive pin into the positive hole. Use the soldering iron and glue to fit the capacitor. Once you’re done, trim the remaining pin with the proper tool.
