Generator Service
Generator Repair & Service That Keeps the Whole Rig Running
Every heater and pump on your rig runs on generator power — when it won’t hold load or trips breakers, the whole job stops. We diagnose, repair, and maintain the generator that keeps your proportioner alive.
What’s Included
Diagnostics, Repair & Maintenance for Rig Power
A generator that idles fine can still fail the moment the rig actually needs it. We test under real load, not just at startup.
Generator Diagnostics & Repair
A generator that trips breakers, won't hold a steady load, or shuts down under startup draw doesn't just lose power — it takes the proportioner's heaters and pumps down with it. We diagnose starting, charging, and control-panel faults so you know exactly what failed and why.
Load & Power-Output Testing
A generator can run fine at idle and still fail the moment your proportioner's heaters and pumps draw full load. We load-test under real working conditions, not just a no-load run, to catch problems that only show up when the rig is actually spraying.
Voltage & Breaker-Trip Troubleshooting
Voltage surges and drops are a common cause of nuisance breaker trips that look like a proportioner electrical fault but actually start at the generator. We trace voltage stability under load before assuming the problem is downstream.
Scheduled Maintenance to Prevent Field Failures
Oil changes, filter service, and electrical panel inspection on a set interval catch wear before it turns into a generator that won't start on a job site with nobody around to fix it.
Electrical Panel & Control Service
The panel that distributes generator power to the proportioner's heaters, pumps, and controls is a common failure point on its own — we service breakers, wiring, and control components, not just the generator engine itself.
Fast-Response Generator-Down Service
A dead generator shuts down the entire rig at once — there's no partial spraying without power. We treat generator-down calls as an emergency priority, not a standard queue item.
Who Needs This
Signs Your Generator Needs Attention
A generator problem rarely announces itself until the rig actually needs full power — catch it before it strands you.
- Your generator won't hold load once the proportioner's heaters and pumps kick in, even though it starts and idles fine.
- Breakers keep tripping and you suspect it's a voltage issue rather than an actual overload.
- The generator is due for scheduled service and you'd rather catch wear now than get stranded on a job.
- A generator failure has already shut your rig down and you need it running again today.

Typical turnaround on-site or in-hand
There’s no partial spraying without power — a generator failure is a whole-rig failure. Scheduled service and load testing catch the wear before it becomes a job-site breakdown.
No generator, no proportioner, no job.

Generator Service FAQ
Why does a generator problem shut down the whole rig?
The generator powers everything on a spray foam rig — the proportioner's primary heaters, the hose heat system, the pumps, and the controls. If the generator can't deliver stable power under load, none of those systems can run correctly, even if the proportioner itself is in perfect condition. A generator failure is effectively a whole-rig failure.
My generator runs fine until the proportioner turns on — what's happening?
This is a classic load-testing gap. A generator can idle and run small loads without issue but fail the moment heaters and pumps draw their full startup and running current. We test under actual working load, which is the only way to catch this kind of failure before it strands you on a job.
Can a generator issue cause proportioner electrical faults?
Yes — voltage surges, drops, and unstable output from a struggling generator can trip breakers and trigger fault codes on the proportioner that look like a proportioner electrical problem but actually originate at the power source. We check generator output stability before troubleshooting the proportioner's own electrical system.
How often should a rig's generator be serviced?
Cadence depends on hours run and duty cycle, but oil, filters, and an electrical panel check on a regular schedule — commonly at [seasonal or hours-based intervals specific to your unit] — catch wear before it becomes a field failure. See our preventive maintenance page for a fuller maintenance-interval framework.
Is generator service available on-site, or does it need to come to the shop?
Most generator diagnostics and repair — load testing, breaker troubleshooting, electrical panel service — can be handled on-site since the generator needs to be tested under your rig's actual working conditions anyway. Ship-in service is available for units needing a full teardown.
