Understanding the Toro S-120 Electric Snow Thrower
The Toro S-120, also known by its model number 38000, is a corded electric, single-stage snow thrower. Unlike its gas-powered cousins, it requires no fuel, oil changes, or complex engine maintenance. Its power comes directly from a wall outlet via an extension cord, making it a straightforward tool for specific jobs.
Its simplicity is its greatest strength, but it also means that when a problem occurs, owners are often unsure where to begin. Most failures can be traced back to a few key areas: the power supply, the safety mechanisms, or the mechanical components. Knowing the basic specifications can help in diagnosing any issues.

The Most Common Problem: Power and Safety Switch Issues
By far, the most frequent reason a Toro S-120 won’t start is an interruption in the power delivery system. This includes everything from the wall outlet to the machine’s internal switch. Always unplug the snow thrower from the extension cord before performing any inspection or maintenance.
Start with the most obvious culprits. Ensure the outlet you are using is functional by testing it with another device. Inspect your extension cord for any cuts, frays, or damage to the prongs. A damaged cord is not only a common point of failure but also a significant safety hazard that must be replaced immediately.
The Safety Key: A Frequent Point of Confusion
A very common issue that stops new and old users alike is the safety key system. The Toro S-120 is equipped with a small plastic key that must be inserted for the machine to operate. This is a safety feature to prevent accidental starting. If this key is missing, loose, or not seated correctly, the machine will be completely unresponsive.
Many owners who acquire this machine second-hand are not even aware the key exists or where it goes. The key slot is typically located in the handle assembly. If the key is lost, a replacement is necessary, but in a pinch, users have reported success by fashioning a substitute from a piece of plastic of a similar diameter to engage the internal switch.
Troubleshooting a Dead Toro S-120: A Step-by-Step Guide
If you’ve confirmed your outlet and extension cord are working and the safety key is properly inserted, it’s time to dig a little deeper. The next logical points of failure are the power plug on the unit itself and the on/off switch in the handle.
These components can wear out or develop poor connections over time. A multimeter is an invaluable tool for safely checking electrical continuity.
Step 1: Inspect the Machine’s Power Plug
The male plug on the snow thrower, where the extension cord connects, can become corroded or charred over time. This creates a poor connection that prevents electricity from powering the motor. Unplug the machine and carefully inspect the metal prongs. If you see significant corrosion or black, burnt marks, this is likely your problem. Cleaning the prongs with a wire brush may offer a temporary fix, but replacing the wiring harness is the correct long-term solution.
Step 2: Check the Handle Switch for Continuity
The switch inside the handle, activated when you squeeze the control bar, is another common failure point. Over years of use, the internal contacts can wear out. With the machine unplugged, you can often test this switch with a multimeter. You would need to access the switch inside the handle housing and check for continuity when the switch is activated. If the switch fails this test, it will need to be replaced.
Mechanical Failures: When It Has Power But Won’t Work
Sometimes the issue isn’t electrical. You might plug in the S-120 and hear the motor hum, but the paddles don’t spin or they turn with no power. This points to a mechanical problem, most likely with the drive belt.
The motor turns a pulley that is connected to the auger (paddles) via a drive belt. If this belt is broken, stretched, or has slipped off the pulleys, the motor will run but won’t be able to transfer power to clear snow. Gaining access to the belt housing will allow you to inspect the belt’s condition. A worn or broken belt is a straightforward replacement that can restore full functionality to the machine.
The Importance of the Scraper Blade and Paddles
Even if the machine runs perfectly, its performance can degrade significantly if the wear parts are not maintained. Worn paddles and a damaged scraper blade will dramatically reduce snow clearing ability. The scraper blade is a nylon strip at the bottom of the housing that helps lift snow off the pavement to be thrown.
As it wears down, the machine will leave a layer of snow behind. Likewise, the rubber paddles are responsible for grabbing the snow and propelling it out of the chute. When they become worn and lose their sharp edge, they can no longer effectively engage with the snow. Both the scraper and the paddles are designed to be replaced and are essential for keeping the S-120 performing at its best.
Long-Term Care and Off-Season Storage
Proper storage is critical for ensuring your Toro S-120 is ready for the first snowfall of the season. After the last use of the winter, wipe the machine down to remove any salt or dirt. Store it in a clean, dry place like a garage or shed.
Pay special attention to the extension cord. Avoid leaving it exposed to the elements. Storing the cord indoors with the snow thrower will prevent it from becoming brittle and damaged. Following these simple steps will not only solve most common problems but also significantly extend the life of this handy electric snow thrower.
