Sewing machine repair. Including the board other shops send back.
We are an electronics bench, not a sewing machine mechanic, and we say so up front: timing, tension and the mechanical tune-up are somebody else's trade. What we take is the half that keeps getting refused. The machine that will not power on. The dead display. The pedal that does nothing. The motor that will not run. On a computerized machine, that is a board fault, and a board we repair instead of replacing.
Diagnosis $49 · free when you approve the repair, and free if it is not worth fixing · one itemized quote before any work starts · parts at cost on the quote
Why there is no price table: the honest answer · the shop's full pricing
Why a sewing machine is an electronics job
The trade treats these as mechanical machines. Most of them have not been mechanical for thirty years.
A modern machine is a computer
A computerized domestic, embroidery or serger machine carries a main board, a switching power supply, stepper motor drivers, a control panel or touchscreen, and a loom of ribbon cables and connectors between them. It is closer to a printer than to a treadle.
And the faults go where the heat is
Power supplies and motor drivers run hot and age out first: dried capacitors, a failed regulator, a cracked joint that opens when the machine warms up. That is why a machine can sew for twenty minutes and then die, or power on once and never again.
So a "dead" machine is usually a small part
A no-power fault is very often one failed component on the supply. A shop that swaps whole boards has to price the whole board and arrives at "not worth fixing." We replace the part, which is a different number entirely, and usually a much smaller one.
This is the same bench that recaps receivers, repairs game console boards and rebuilds power supplies, pointed at a machine nobody else wants to open. The electronics do not care what the machine sews.
What we fix
The electrical and board side of a sewing machine, serger or embroidery machine. Quoted after we look, because the fault sets the number, not the model.
Won't power on at all
Quoted after we lookThe most common thing people bring us. On a computerized machine this is usually the power supply or the main board; on an older machine it is often the pedal, the cord, the motor or an aged capacitor. The diagnosis finds out which.
Control and main boards
Component-level repairFailed regulators, dried capacitors, cracked joints, damaged traces, blown drivers. We repair the board instead of replacing it, which is what makes a machine other shops call dead into a normal job here.
Power supplies
Quoted after we lookInternal and external supplies, wall adapters and the regulator section on the board. The hottest parts of the machine and the first to fail, so they are the first thing we check on a no-power complaint.
Foot pedals & speed control
Quoted after we lookA pedal that does nothing, runs flat out, or only works at one angle is a control problem, not a motor problem. Cord, potentiometer or carbon pile, switch, and the connector at the machine end.
Motors & motor control
Quoted after we lookA motor that hums and will not turn, runs at one speed, loses power when warm, or smells hot. Brushes, windings, capacitors, the drive circuit, and the mechanical drag that overloads it.
Wiring, harnesses & connectors
Quoted after we lookIntermittent faults, a machine that works only when the cable is held a certain way, corroded or heat-damaged connectors, and ribbon cables with a broken conductor. Often the cheapest repair on this page.
Control panels & displays
Quoted after we lookDead LCD, flickering or blank segments, a keypad where half the buttons no longer respond, a touch panel that misses taps. Panel, ribbon and driver repair.
Lighting & the lamp circuit
Quoted after we lookLamps, LED retrofits and the supply feeding them. A shorted lamp circuit can take down more than the light, so it is worth fixing rather than ignoring.
Sergers & embroidery machines
Quoted after we lookSame electronics, more of it. Bring the machine, or just the board if you can remove it, and we will work on the bench.
Vintage & mechanical-era machines
Quoted after we lookOlder domestic machines are simple electrical devices: a motor, a capacitor, a pedal and a switch. When one of those is the fault it is a straightforward repair, and the parts are generic.

Machines a shop already gave up on
Quoted after we lookIf another shop told you the board is dead and the machine is not worth repairing, that is worth a second opinion before it goes in the bin. Sometimes they are right, and sometimes they simply do not repair boards.
Board repair, mailed in on its own
Quoted after we lookIf you can unplug the control board, you can box the board and ship it without the machine. Far cheaper to ship, and often all we need. We will tell you whether that is enough for your fault.

What we don't do
This matters more than the last section. We would rather send you to the right person than take a job we are wrong for.
Straight about the line
We are an electronics bench. There is a real sewing machine trade that does mechanical service, and it is not ours. Here is exactly where the line falls.
- We do not do mechanical tune-ups. Cleaning, oiling, and adjusting a machine to sew correctly is the mechanic's job. If that is all you need, ask us and we will point you at someone who does it well.
- We do not do timing, tension or stitch quality. A machine that skips stitches, birds-nests, or sews a bad seam is usually mechanical, and it is not what we are good at. We will say so.
- We do not do feed dogs, needle bar, presser foot or hook work. Same reason.
- We will not repair a board that is not the fault. The $49 diagnosis exists so we confirm the cause before quoting. If the electronics are fine and the problem is mechanical, you get that answer and a free diagnosis instead of an invoice.
- We do not guarantee a machine will then sew perfectly. We guarantee the electrical and board repair. If a machine arrives with an electronics fault and a mechanical fault stacked behind it, we fix our half and tell you plainly what is left.
If your fault is mechanical, the honest move is a sewing machine mechanic. If your machine will not power on, has a dead panel, or a shop called the board dead, that is exactly our call. Not sure which one you have? Ring the shop and describe it, or run the repair wizard for a first read before you box anything.
How it goes
Diagnosis first, then one itemized quote. You approve before anything starts.
The five steps
- 01Diagnose. $49, free when you approve the repair. We find the actual failing part, powered up and warm, not just cold on the bench, and we tell you whether it is really electrical.
- 02Itemized quote. One quote listing the repair and the parts at cost. You approve it before any work starts, and there is no hourly meter running.
- 03Repair. The board is repaired at component level where it can be: failed regulators, aged capacitors, cracked joints, damaged traces and dead drivers replaced with correct parts. Desoldered with proper tooling rather than pried out.
- 04Burn-in and test. The machine runs long enough for a marginal joint or a wrong part to fail here, on the bench, instead of in your hands next week. You get the test result.
- 05Home again. Picked up in Longmont or shipped back, packed for the trip. You can watch the whole thing from the tracking page.
Mail it in, from anywhere
A sewing machine is one of the few things people ship us that genuinely travels well.
Why the mail-in lane exists for this
Sewing machine repair is a trade in retreat: shops close, technicians retire, and the nearest one to you may be an hour away and booked out for weeks. The electronics side of the job does not need to be local. If you can find a box and some bubble wrap, you can use this bench.
- →Box the machine, or just the board if you can remove it. The board alone is far cheaper to ship and often all we need.
- →Return shipping is included up to 15 lbs packed; heavier tiers are a flat rate and quoted before we ship.
- →The day your box lands we email you, and the tracking page carries the status from there.
Sewing machine questions
The things people actually ask before they carry a machine in.
Straight answers
No, and that is on purpose. We are an electronics bench. Timing, tension, feed dogs, needle bar height and the mechanical tune-up are the work of a sewing machine mechanic, and we will tell you that straight rather than take a job we do not do well. What we take is the electrical and board side: the machine that will not power on, the dead display, the pedal that does nothing, the motor that will not run or runs at one speed.
Usually yes, and it is the most common thing people bring us. On a computerized machine a no-power fault is almost always the power supply or the main board, which is exactly what we repair. On an older machine it is often the pedal, the cord, the motor or a failed capacitor. Bring it in or mail it: the $49 diagnosis finds out which one you have, and it is free when you approve the repair.
Because the usual reason a shop says that about a computerized machine is the board, and most repair shops swap boards rather than repair them. A replacement board is often expensive enough that the shop is right to call the machine uneconomical. We repair the board at component level instead, which is a different and usually much smaller number. If it truly is not economical, the diagnosis is free and we will tell you that too.
The diagnosis is $49 and it is free when you approve the repair. After the diagnosis you get one itemized quote and you approve it before any work starts. We do not publish a sewing machine price table yet because the range across a vintage mechanical machine and a modern embroidery machine is enormous, and a made-up average would help nobody. The quote is the number, and parts are listed on it at cost.
Yes, on the electronics side. Sergers and embroidery machines are full of boards, sensors and motors, and those faults are squarely our work. Bring the machine or just the board if you can remove it.
Yes, and it is the reason this page exists nationally. A sewing machine travels well packed. Mail-in is welcome from anywhere in the U.S., return shipping is included up to 15 lbs packed, and the tracking page keeps you posted from the day the box lands.
Your quote carries the turnaround, and it is measured in days on the bench rather than weeks sitting in a queue. Mail-in adds shipping both ways; diagnosis starts the day the box arrives.
For electronics, usually. Capacitors, regulators, motor drives, connectors and common board parts are standard components, and vintage domestic machines are simple enough that the parts are generic. Where a part is genuinely unobtainable we tell you before you commit instead of after.
Wondering whether the machine is worth fixing at all? The fix-or-replace take on aging gear covers the math in plain language.
