Portable Generator Repair in Wheaton & DuPage County
Find out why your portable generator won’t start or stay running before you need it for the next job. CAI Machine & Repair provides portable generator diagnostics, small-engine repair and maintenance for customers in Wheaton and throughout DuPage County.
Describe how the generator is failing
A generator that will not crank presents a different starting point from one that starts and then stalls. Include the model, fuel type, storage history and whether the problem occurs with or without equipment connected. Do not assume an engine repair alone will resolve an electrical-output complaint.
- No-start or hard-start conditions
- Surging, stalling and rough running
- Fuel-system and carburetor concerns
- Starter or other mechanical faults
- Maintenance and condition checks before returning to use
Portable equipment service with a clear scope
CAI’s generator work is part of its powered-equipment repair service. Text the identification label and symptoms so we can discuss the right next step. For a permanently installed standby system, transfer switch or building wiring issue, confirm the scope before booking; this page covers portable generator equipment service.
Arrange service before the next outage or project
Appointments, parts availability and the condition of the generator determine timing. Mobile diagnostics or pickup and delivery may be appropriate depending on the job. Share any deadline when you inquire so availability can be discussed before you rely on the equipment.

Before you book
Can you assess a generator that sat unused for a season?
Contact CAI with the make, model, storage history and symptoms. A condition assessment helps determine maintenance and repair needs before the generator returns to use.
What if the engine runs but the generator has no output?
Mention the output problem when you contact CAI. That symptom needs a different assessment from a no-start engine complaint, and the equipment and fault must be reviewed to confirm service scope.
