Wednesday evening in Boston, and rain’s tapping against my window. I’m ready for a quick walk to clear my head after work. I step onto my FUNMILY treadmill, press start, and get nothing but silence. My FUNMILY treadmill not working felt like a small betrayal, it worked perfectly fine yesterday. If you’re standing there right now, staring at buttons that won’t respond, feeling confused and maybe a little annoyed, I’ve been exactly where you are.

The Day My FUNMILY Treadmill Decided To Take a Break
It was Wednesday evening. Rain outside. My floor still a little dusty.
I hit “Start.” The treadmill gave me silence.
I pressed again. Harder this time. Still nothing.
I laughed. Then sighed. Then sat on the edge like it might answer me.
Real life. Slight frustration. But still calm.
Stood there wondering if I’d somehow offended it. Sounds silly now.
Why Your FUNMILY Treadmill Might Not Be Working
Before we start troubleshooting, take a breath.
Most issues are simple. Really simple.
Your treadmill probably isn’t broken. It just needs attention.
Let’s look at what usually causes problems.
Power Issues (The First Thing To Check, Always)
Start here every single time.
- Plug straight into the wall – Skip power strips if possible
- Check the rear power switch – Make sure it’s fully ON
- Look for loose connections – Push plugs in firmly on both ends
- Check for frayed cables – Look along the entire cord
- Burnt smell? – Unplug immediately and stop
My first “dead treadmill” scare was just a loose plug. Pushed it in. Problem solved. Felt relieved and silly at the same time.
Safety Key Missing or Loose
That little magnetic key matters more than you think.
FUNMILY won’t start without it properly attached. Not even a tiny bit.
- Take the key completely off
- Wipe the contact area clean with a dry cloth
- Push it back firmly until you hear a click
- Try starting again
I once spent 15 minutes troubleshooting before realizing the safety key was crooked. One firm push fixed everything instantly.
Tripped Circuit or Voltage Drop
Older homes plus treadmills equal popped breakers.
Treadmills pull more power than most appliances.
- Walk to your breaker box
- Look for switches that are halfway flipped
- Turn it fully off, then back on
- Try plugging into a different wall outlet
Avoid extension cords and cheap power strips. They can cause voltage drops.
My apartment’s breaker tripped twice before I learned to use a dedicated outlet. Haven’t had issues since.
When the Console Turns On, But The Belt Won’t Move
Okay. Lights work. Screen glows. You press start and… the belt doesn’t move.
Common problem. Usually simple fix.
Belt Alignment and Tension Problems
Your belt might need help.
- Drifting left or right – Needs rear screw adjustment
- Feels sticky or jerks – Probably needs lubrication
- Makes squeaking sounds – Definitely needs lube
Use silicone lubricant made for treadmills. Not cooking oil. Please.
I tried vegetable oil once because I was impatient. Bad decision. Made everything sticky and weird. Don’t be me.
Motor Struggling Under Load
Motors show warning signs when they’re unhappy.
- Buzzing or whining noises – Not the normal hum
- Belt stops suddenly – Motor overheating or struggling
- Slight plastic smell – Electronics getting warm
If it smells like warm electronics… step off like a ninja. Slowly.
I ignored a grinding noise for three days once. Ended up replacing a drive belt. Expensive lesson about paying attention to warning signs.

Console, Buttons, and Random Tech Glitches
Sometimes the problem isn’t mechanical at all.
It’s the computer brain acting weird for no good reason.
Frozen Console
Screen’s lit but nothing responds? Been there.
- Unplug the entire treadmill
- Wait 60 to 90 seconds minimum
- Plug back in
- Power on and test again
Check gently for loose console wires too. Don’t yank anything. Just look.
Mine had a partially disconnected wire once. Pushed it back in. Fixed instantly.
Wrong Mode or Paused Program
This sounds obvious. But it happens.
- Make sure it isn’t paused
- Switch to manual mode and try again
- Reset speed back to zero
- Restart from scratch
I once pressed pause by accident and didn’t realize for 10 minutes. Just stood there pressing buttons. Felt ridiculous when I figured it out.
Simple Fixes You Can Safely Try First
Before calling anyone, try these basic steps.
They’re easy. Safe. And solve most problems.
- Unplug everything – Wait a full minute. Plug back in.
- Re-seat the safety key – Take it off. Put it firmly back.
- Wipe dust away – Clean around vents and buttons.
- Lubricate the belt – If it feels dry or squeaks.
- Tighten loose screws – Check frame and handrails.
These steps feel productive. Still completely safe.
I do these checks every couple weeks now. Takes five minutes. Prevents bigger headaches later.
Things You Should NOT Touch (Even If You’re Curious)
DIY has limits. Learn from my mistakes.
Some things you should absolutely leave alone.
Don’t Open the Motor Housing
Just don’t. Trust me.
- Shock risk – Even unplugged, parts can hold charge
- Easy to fry boards – One wrong touch destroys circuits
- Goodbye warranty – Companies void coverage if you’ve been inside
I almost opened mine once. My neighbor who fixes electronics stopped me. Said it wasn’t worth the risk or the warranty loss.
Don’t Bypass Safety Sensors
Never disable safety systems.
- Don’t tape the key permanently – That prevents face-plants
- Don’t “bridge” wires – Extremely dangerous
- Don’t jump circuits – Seriously, don’t
Those sensors protect your bones. And your ego when you trip.
Safety features exist because someone learned a painful lesson. Don’t repeat their experience.
When It’s Time To Call FUNMILY Support or a Technician
Sometimes you need professional help. That’s completely okay.
Really.
- Smoke, sparks, or burning smell – Stop immediately
- Repeated shutdowns mid-walk – Happens every time
- Error codes you can’t clear – Keeps showing messages
- Still dead after trying everything – You’ve done the basics
- Under warranty? – Definitely contact FUNMILY support
Take photos of error screens. Record weird sounds on your phone.
Writing “soft buzzing from the motor area” helps techs diagnose faster than saying “it sounds broken.”
I called support once. They were patient. Asked good questions. Walked me through detailed checks. Sent a free replacement part since I was under warranty.
Final Thoughts, Be Patient, Don’t Force It
Most FUNMILY treadmill issues are fixable.
Loose connections. Dirty contacts. Software glitches. Dry belts.
Sometimes you just need a reset. Or a cup of tea while you wait.
If you’re unsure about something, let the pros handle the inside stuff.
I once spent an hour troubleshooting in frustrated circles. Got annoyed. Made dinner. Came back with fresh eyes.
Tried one more time. It worked. No idea what changed. Maybe it just needed the break as much as I did.
Final Recommendation
Here’s what I’d tell my past self when my FUNMILY treadmill first stopped working:
Start with the boring obvious stuff. Check power. Check safety key. Reset the breaker.
If the console’s frozen, unplug for a full minute. This fixed mine three different times.
If the belt won’t move, check if it needs lubrication. Listen for grinding or buzzing.
Don’t open the motor area. Don’t mess with wiring. Also, Don’t force parts that feel stuck.
And if something smells burnt? Stop everything immediately. Call support or a tech.
My FUNMILY works great now. I check it weekly. Quick wipe down. Belt lube monthly. Tighten screws when I notice wobble.
Takes about 10 minutes per month. Prevents way bigger problems.
Your treadmill probably isn’t dead. It probably just needs one simple fix.
Try the steps above. Stay patient. And remember that warranties and repair professionals exist for good reasons.
You’ll be walking again soon. Promise.
FAQs
A FUNMILY treadmill not working often means no power. Check the wall outlet, power cord, fuse, and make sure the safety key is fully inserted.
This usually points to the safety key or a sensor issue. A loose walking belt can also stop the motor from engaging.
Sudden stops often happen from belt friction or motor overload. Poor belt lubrication or extra weight can trigger auto shutdown.
Yes, a loose belt can slip and stop movement. Proper belt tension helps the motor run smooth and steady.
Noise without movement often means belt slip. Worn rollers or motor strain are also common causes.
A reset can clear small errors. Unplug the treadmill for five minutes, then plug it back in and test it again.
If basic checks fail, service is needed. Motor, control board, or sensor faults usually require professional repair.
