Care & maintenance
Reformer troubleshooting guide
The short answer
Most reformer problems trace to four causes: debris on the rails, worn carriage wheels, loose frame hardware, or fatigued springs. Working through those four in order resolves the large majority of complaints without needing a technician.
Diagnose with the springs off
Detach all springs and push the carriage slowly through its full travel, listening and feeling. Spring noise masks everything else, and removing it makes the actual fault obvious.
A gritty feel throughout means debris. A tick at the same point each stroke means a wheel. A rattle only under load means loose hardware.
| Symptom | Most likely cause | Fix |
|---|---|---|
| Gritty feel throughout travel | Debris on rails | Clean rails thoroughly |
| Tick at same point each stroke | Flat spot on a wheel | Replace wheel set |
| Rattle only under load | Loose frame bolts | Check and snug all bolts |
| Hard knock on return | Compressed carriage stoppers | Replace stoppers |
| Resistance feels lighter than before | Fatigued springs | Measure free length; replace set |
| Carriage pulls to one side | Uneven rope length or wheel wear | Reset ropes; check wheels |
| Squeak under load | Dry pulley bearing | Spin-test pulleys; replace if rough |
Start with the free fixes
Clean the rails and check every bolt before buying anything. Between them they resolve most reported problems, and both cost nothing.
Only after those two should you start replacing parts, because a new wheel on a dirty rail behaves exactly like the old one.
When it is not the machine
A carriage that feels different is sometimes an uneven floor rather than a fault. Check the levelling feet and confirm all four are in contact — a machine rocking on three feet feels loose in a way that resembles worn wheels.
Equally, a machine moved to a new room can feel different simply because the floor is more or less compliant.
When to call a technician
Frame damage, a racked frame that measures out of square, or a scored rail. All three are structural, none are DIY repairs, and continuing to use the machine makes them worse.
Everything else on the list above is within reach of anyone with basic tools and half an hour.
Frequently asked questions
- Why does my reformer carriage feel rough?
- Usually debris on the rails. Clean them thoroughly first — it resolves this more often than any other single action and costs nothing.
- Why does my reformer rattle?
- Loose frame bolts, particularly in the first year as the frame settles. Check and snug every bolt before investigating anything else.
- Why does the carriage pull to one side?
- Uneven rope length or uneven wheel wear. Reset both ropes to matching length by measurement, then spin-test each wheel.
- When should I call a technician?
- For frame damage, a frame that measures out of square, or a scored rail. Those are structural and get worse with continued use.
