The NordicTrack C990 treadmill reviews all land in the same place. It is a sturdy, fairly quiet folding treadmill for walkers and light joggers, with a 3.0 CHP motor, a 20" x 60" deck, and iFit support. It is also discontinued, and its console feels dated. Buying one used makes sense at the right price and after a proper inspection. Paying full price for a new one does not.
The C990 is a home treadmill from NordicTrack’s older C Series. It sold new for under $1,000 and borrowed features from pricier machines, including a 7-inch touchscreen, 32 built-in programs, adjustable deck cushioning, and a 12% incline. Most buyers today are not asking whether it was good when it launched. They want to know whether it still holds up and what to check before spending money.
We review treadmills at Big Guy Treadmill Review with heavier and larger-framed users in mind, so we care about frame strength, motor quality, and honest weight ratings. This article pulls together what testers and owners report about the C990’s features, build, and problems. It also shows how to judge a new or used unit.
Why the C990 still gets so much attention
The C990 still draws searches because it packed features usually found on more expensive treadmills into a budget price. Testers called it the best build quality in its class at launch, and the used market now makes it cheaper still. It remains a reasonable entry point for someone easing into regular exercise at home.
What the C990 offers on paper
Specs matter more than marketing here, and published figures do not always agree. Use the table as a starting point, then confirm details on the machine itself.
| Spec | Published figure |
|---|---|
| Motor | 3.0 CHP |
| Running surface | 20" x 60" (one tester measured 19.75" wide) |
| Speed | Up to 12 mph |
| Incline | 0 to 12%, adjusts in 0.5 steps, no decline |
| Cushioning | FlexSelect, adjustable deck firmness |
| Console | 7-inch touchscreen with Wi-Fi, iFit capable |
| Programs | 32 built in, plus iFit |
| Weight capacity | 300 lb or 325 lb, depending on the source |
| Size in use | 78.3" L x 35.75" W x 56.4" H |
| Size folded | 35.75" W x 43" L x 70" H |
| Warranty | Lifetime frame and motor, 3-year parts, 1-year labor |
Weight capacity is the figure that disagrees most, and some listings also call the console an LED display. Owners describe a touchscreen. If you weigh over 250 lb, read the rating label on the machine before you commit.
The C990 is a good-value machine on paper, but verify the weight rating and console on the exact unit you plan to buy.
Who the C990 fits best
Walkers and light joggers get the most from this treadmill. The 3.0 CHP motor handles steady jogging smoothly, and an owner who sprinted at 8 mph found it felt solid. It is a sensible pick if you are rebuilding fitness or want a quiet machine for daily walks.
It fits less well if you run often or run long. Testers suggest a bigger motor for frequent runners. Taller users should also be careful, since a 5’7" tester found the short handrails and fan position awkward. The reviews on this model are clear that it is a mid-pack home machine, not a heavy-duty runner’s treadmill.
What reviews say about performance and build quality
Across NordicTrack C990 treadmill reviews, the same strengths come up. The deck feels stable, the motor runs smoothly through speed and incline changes, and the entertainment features beat most treadmills at this price. The weak spots are cushioning for longer runs and the single fan.
Deck, cushioning, and stability
An owner reported that the machine felt solid underfoot at sprint speeds, though she had to shim the rear wheel because her basement floor was uneven. A treadmill that rocks will feel worse than any spec sheet suggests, so level it first.
FlexSelect cushioning uses six shocks under the deck. A half turn on each one switches the deck between a softer feel and a firmer, roadlike feel. It helps, but it has limits. One tester with a prior injury found the deck uncomfortable after 20 minutes of jogging. If your joints are sensitive, plan for a more cushioned machine or keep your runs short.
Motor, noise, and cooling
The 3.0 CHP motor is quiet for its class and changes incline and speed without strain. One test with a 44 dB room measured the treadmill with its fan running at three speeds:
- 1 mph: 54 dB
- 6 mph: 63 dB
- 12 mph: 71 dB
The fan is a weak point. There is only one, and it only cools you well on the top two of its five settings. Its position is fixed, so you get the best breeze standing near the console.
Console, iFit, and entertainment
The touchscreen is responsive and connects over Wi-Fi. It runs 32 built-in programs covering heart rate, calorie burn, intensity, incline, and speed. With an iFit subscription, a coach guides the workout and changes your speed and incline for you. One owner called that the main reason she bought the machine.
You do not need iFit to use the treadmill. Dual speakers are louder and clearer than most budget rivals, and an audio jack, tablet holder, and accessory tray are included. New units shipped with a year of iFit, but that does not apply to a used machine.
The C990 earns its reputation on stability, quiet power, and entertainment, not on cushioning or cooling.
Common problems with the NordicTrack C990
The most common complaints about the NordicTrack C990 are console limits and a few design quirks, not breakdowns. None of them are dealbreakers, but you should know them before you buy.
Console and connectivity limits
Bluetooth is limited. An owner could not play music through the speakers over Bluetooth, and the audio jack was the only way to do it. She also could not connect the iFit app to the console. The touchscreen controls everything, so you cannot start the belt until you pick a workout. You also have to stop, rate, and exit to the main screen before switching. Owners also call the interface less than intuitive at first.
Deck, rails, and folding quirks
The belt sits slightly higher than on most treadmills and flares upward at the edges. The side rails slant inward, so a foot that wanders onto them can catch the belt. That is a real concern for anyone with a wider stance. The machine does not decline either, and none of its competitors at this price do.
Folding is easy with the shock-assisted EasyLift design, but the release latch sits under the deck and is awkward to reach. On concrete or other hard floors, the four wheels can let the machine roll away while you fold it. A mat under the treadmill solves that.
Reliability and warranty
The warranty covers the frame and motor for life, parts for three years, and labor for one year. Reviewers called the parts coverage short next to some other NordicTrack models. Consumer Reports put the C990 through a durability test simulating about half a year of use and saw only minor wear.
A used unit is another story. The last C990 models date to around 2018, so any machine you find is well past its parts coverage. Assume the warranty does not transfer unless the seller proves otherwise.
Expect annoyances more than failures, and price a used C990 as if the warranty is gone.
How to decide if a C990 is worth buying new or used
A used C990 is worth buying when it passes a hands-on inspection and sells well below its original price. A new one is only worth it if you find fresh stock with a solid return policy. Either way, check the NordicTrack C990 treadmill reviews against the specific unit in front of you.
Is buying new still an option?
Not really. NordicTrack no longer sells the C990, and the closest current line is the T Series. Some third-party listings may still show new stock, so confirm the seller, the return window, and whether assembly and delivery are included. Early buyers paid for delivery to the room and often paid extra for professional assembly. A treadmill this size takes about 1.5 hours to build with a pro.
A used inspection checklist
Take this list with you when you see a used machine:
- Check the label for the model number and weight rating.
- Walk the belt at low speed, then run it at a higher speed. Listen for squeaks, grinding, or slipping.
- Run the incline from 0 to 12% and back, watching for hesitation.
- Test the touchscreen across every corner and confirm it connects to Wi-Fi.
- Ask the seller to sign out of any iFit account before you leave.
- Fold and unfold the deck, then check that the belt stays centered.
- Look at the deck and belt for worn patches or fraying.
- Confirm the power cord and plug are undamaged.
What a fair used price looks like
One Canadian listing asked CAD $350 for a used C990, which shows where asking prices can sit. As a rule of thumb, pay well under half of the original price. Then add moving and setup costs. A machine this heavy often needs two people and a vehicle to move.
A used C990 is a bargain only when it is cheap enough to cover the cost of a belt, a mat, and a bad surprise.
What to buy instead of the C990
If you cannot find a clean C990 at a good price, buy a current machine instead of gambling on an old one. The closest NordicTrack replacement is the T Series, and heavier or more serious runners should look at stronger machines.
Closest NordicTrack replacements
The T Series is the comparable current line, with the 6.5 as the least expensive and the 8.5 one step up. Reviewers also recommend the NordicTrack Commercial 1750 treadmill as a step up. It has a stronger motor, a touchscreen, and automatic incline and decline. Our treadmill shopping guide walks through budget, space, folding, and motor quality in detail.
When to step up or shop the field
If you run regularly or need high weight capacity, skip the budget tier. The 3G Cardio Elite Runner X is our highest rated treadmill at 95/100, with a commercial-grade build. If you just want a short list, see our treadmill award winners, including the Best Under $1,000 pick.
A discontinued bargain is still a gamble, so compare it against what you can buy new today.
The verdict on the C990
The C990 is a good treadmill for walking and light jogging. It is stable, quiet, and well equipped for its era. Its limits are a dated console, modest cushioning, a single fan, and no warranty to lean on if you buy used. Buy it only if it passes a hands-on check and the price is low.
