Motor diagnostic
Five-step diagnostic. About 60 percent resolve at brushes, capacitor, or interlock.
When a commercial food processor powers on but the motor won't run, the most common causes are a worn lid safety interlock ($180–$280), a failed start capacitor (a hum with no spin, $80–$180), and worn motor brushes ($120–$220) — together about 60% of motor calls resolve at this work. Our techs go cheapest-first: power supply, then interlock, then capacitor, then brushes, then the Hobart Buffalo Chopper drive coupling ($280–$440), and only then a full motor ($580–$880 Robot Coupe, $880–$1,400 Hobart). On a Buffalo Chopper chassis built for 20 years, even a year-12 motor still pencils as a repair. The interlock is a safety device — we replace it, never bypass it. The $120 commercial diagnostic is waived when you approve the repair.
Commercial food processor motor failures cluster around five mechanisms. (1) Power supply (~5 percent of calls). (2) Safety interlock wear year 5-8, $180-280. (3) Capacitor failure year 6-9, $80-180. (4) Motor brushes worn year 6-9, $120-220. (5) Drive coupling year 7-10, $280-440 (specific to Hobart Buffalo Chopper architecture). Full motor replacement year 12-15 Hobart premium ($880-1,400), year 8-11 Robot Coupe ($580-880).

FAQ
Robot Coupe powers on but motor won't run. Most common?
Safety interlock at lid (Robot Coupe requires lid fully closed for motor to run). Year 5-8 typical interlock wear, $180-280 replacement. Or capacitor failure ($80-180).
Hobart Buffalo Chopper drive coupling — what is it?
Buffalo Chopper has a drive coupling between motor and bowl-rotation mechanism. Year 7-10 typical wear, $280-440 replacement. Specific to Buffalo Chopper architecture — Robot Coupe doesn't have equivalent.
Motor brushes vs full motor replacement decision?
Brushes ($120-220) first; if motor still doesn't run after brush replacement, full motor ($580-1,400). Most calls resolve at brush replacement; full motor replacement is year 8-15 typical.
Lid safety interlock — Cal/OSHA matter?
Yes, Cal/OSHA + manufacturer safety design. Don't bypass interlock to keep equipment running. Replace failing interlock $180-280.
Year 12+ Hobart Buffalo Chopper with motor failure — repair?
Yes, usually justifies repair. Hobart Buffalo Chopper chassis is built for 20-year service life. Motor replacement $880-1,400 on year-12 unit (retail $4,500-8,500) is sound investment.
Robot Coupe year 9 motor failure — repair vs replace?
Borderline. Year-9 Robot Coupe with $580-880 motor replacement on $2,500-4,500 unit is sound investment if other components are fine; if multi-component failure, leans replace.
My commercial food processor hums but won't spin. Is it safe to leave on?
No — switch it off. A food processor that hums but won't spin is energizing the motor without it starting, the classic failed-start-capacitor symptom ($80-180 to replace). Leaving it powered in that locked state overheats the windings and can turn an inexpensive capacitor job into a $580-1,400 motor replacement. Before that, confirm the lid and bowl are fully seated, since a safety interlock that won't close keeps the motor from starting too. Power it down, and our techs will test the interlock, capacitor, and brushes in order. The $120 commercial diagnostic is waived when you approve the repair.
My food processor motor runs but the blade or bowl won't turn. What's wrong?
When the motor clearly runs but the blade or bowl doesn't turn, the drive connection between the motor and the cutting assembly has failed. On a Robot Coupe that's the drive coupling between the motor shaft and the blade spindle; on a Hobart Buffalo Chopper it's the drive coupling between the motor and the bowl-rotation mechanism (year 7-10, $280-440). The coupling is designed to wear or shear before the motor does, so a spinning motor with a still blade is usually a coupling, not a dead motor — which is the cheaper outcome. Our techs confirm the motor turns, then inspect and replace the coupling and check the spindle and bearings. The $120 commercial diagnostic is waived when you approve the repair.
