Who should not use an elliptical?
People who should not use an elliptical include anyone with uncontrolled medical conditions, significant balance or movement-control problems, or anyone who feels pain or dizziness while exercising. For the Nordictrack NEL07940 elliptical machine, follow the safety limits and precautions in the NEL07940 owner's manual.
Who should avoid using an elliptical (or get medical clearance first)
We recommend a physician consult before starting, especially if any of these apply:
- You are over age 35 and have not been exercising regularly.
- You have a pre-existing health problem (heart, blood pressure, joint, or neurological conditions).
- You experience pain, dizziness, faintness, or unusual shortness of breath during exercise.
- You have balance issues or difficulty controlling movement (higher fall risk when mounting and dismounting).
- You exceed the equipment user weight limit; the NEL07940 is rated for 250 lb maximum user weight.
Safety reminders specific to the Nordictrack NEL07940
The manual highlights several points that matter for injury prevention:
- Hold the handlebars or handgrip pulse sensor when mounting, dismounting, and using the machine.
- Keep your back straight while exercising; do not arch your back.
- Stop immediately and cool down if you feel pain or dizziness.
- Wait for the pedals to come to a complete stop before stepping off; this model does not have a free wheel.
Quick decision guide
| Situation | What we recommend |
|---|---|
| New to exercise, age 35+ | Get medical clearance; start with short, low-resistance sessions |
| Knee/hip/back pain during use | Stop; adjust stride posture and resistance, then consult a clinician if pain persists |
| Balance concerns | Use extra support, consider a lower-risk cardio option, or have supervision |
| Over 250 lb | Do not use; choose equipment rated for your weight |
Why it matters
Ellipticals are low-impact, but they still require coordinated stepping and stable posture. If balance is limited or symptoms like dizziness occur, the risk of falls and overuse injuries increases, especially during mounting and dismounting.

Why is my NordicTrack elliptical not working?
If your Nordictrack NEL07940 (CX 925) elliptical is not working, the most common causes are low console batteries, a loose wiring connection to the console, or a safety-related condition where the machine is not stable or parts are loose. Start with the battery and connection checks in the NEL07940 owner's manual.
Quick checks we recommend first
- Confirm the console powers on; if the display is dim or resets, replace the console batteries (low batteries cause most console issues).
- Inspect and tighten visible fasteners; the manual recommends tightening parts regularly and replacing worn parts immediately.
- Check that the machine is level and not rocking; adjust the rear leveling feet as needed.
- Let the pedals come to a complete stop before stepping off; this model does not have a free wheel.
- If you recently moved it, recheck connections and hardware after relocation.
Console power and display problems
Most “dead” or unstable console symptoms trace back to batteries.
| Symptom | Likely cause | What to do |
|---|---|---|
| Display is blank | Batteries installed incorrectly or dead | Replace batteries; verify polarity and contacts |
| Display is dim | Low batteries | Replace batteries |
| Fan use resets console | Low batteries | Replace batteries |
| Buttons respond inconsistently | Battery/contact issue or loose harness | Replace batteries; reseat connections |
Mechanical issues that can feel like “not working”
If the console works but the motion feels wrong (binding, squeaking, or uneven pedal travel), focus on the drive and pivot points.
- Lubricate moving joints sparingly with black & decker exercise equipment lubricating grease 104838 if you have dry, noisy pivots.
- If you hear grinding or feel rough rotation at the crank area, a worn bearing is a common cause.
- If the pedals move but slip or feel inconsistent under load, inspect the belt and pulleys for wear.
Why it matters
A “not working” elliptical is often a simple power issue (batteries or connections), but ignoring looseness, rocking, or worn bearings can accelerate wear on the drive system and make the machine unsafe to use.

Can an elliptical be fixed?
Yes, a Nordictrack NEL07940 (CX925 elliptical machine) can usually be fixed. Most problems come from normal wear, loose hardware, low console batteries, or lack of lubrication; with basic troubleshooting and the right replacement parts, you can restore smooth, safe operation.
What we fix most often (and what to check first)
- Rocks or feels unstable: level the machine using the rear leveling feet.
- Console issues (dim display, resets): replace the console batteries; many console problems trace back to low batteries.
- Noisy, rough, or stiff pedal motion: inspect for worn bushings or bearings and check for dry pivot points.
- Resistance problems: verify wiring connections and inspect the resistance drive components.
- Loose or wobbly arms/pedals: tighten fasteners and inspect for worn hardware.
Quick DIY repair plan for NEL07940
- Unplug or remove batteries before working around moving parts or wiring.
- Tighten and inspect hardware; the manual recommends regularly tightening parts and replacing worn parts immediately.
- Level the frame if it rocks.
- Address friction points with the correct lubricant and inspect wear items.
- Test the console and sensors after reassembly.
Common symptoms and likely fixes
| Symptom | Most common cause | Typical fix |
|---|---|---|
| Console resets or display is dim | Low batteries | Replace batteries; retest |
| Elliptical rocks | Uneven floor or feet out of adjustment | Adjust leveling feet |
| Squeaks/clicks while pedaling | Dry pivots, worn bushing/bearing | Lubricate; replace worn parts |
| Resistance does not change | Loose connection or failed resistance component | Check wiring; replace failed part |
Parts that often help
- Use exercise-equipment grease on pivot points where the manual allows lubrication: black & decker exercise equipment lubricating grease 104838
- If you have grinding or side-to-side play at rotating joints, inspect wear items such as: reebok elliptical crank bearing 139703
Why it matters
Fixing an elliptical is not just about comfort. A rocking frame, worn bearings, or loose fasteners can accelerate wear on the flywheel and drive system, and it can create a safety risk because the pedals keep moving until the flywheel stops.
For model-specific maintenance steps, leveling instructions, and console troubleshooting, follow the NEL07940 owner's manual.
