When a facility backup generator fails, the problem can affect far more than the lights. Pumps, refrigeration, controls, and other essential systems depend on power that starts and carries the required load.
WB Engine Repair provides mobile industrial and facility backup generator repair across Utah. As a Cummins Onan Generator Authorized Dealer, we diagnose generator faults, explain the repair options, and work on installed systems at their operating site when conditions allow.

An engine may run normally without demand but overheat or shut down once the generator is carrying a load. Fuel supply, cooling performance, controls, and the generator’s operating conditions can all be relevant. We diagnose the cause before recommending repairs.
A running generator does not always mean power has reached the building. The concern may involve generator output, controls, transfer operation, or another part of the facility power system. Share any displayed alarms and describe what happened during the outage or test so we can assess the appropriate components.
Installed backup generators are often best assessed where they operate. Our mobile service allows us to inspect the system on site when access and working conditions permit. Before a visit, we discuss the generator’s location, access requirements, symptoms, and any planned testing that could affect facility operations.
What to Provide When You Call
Please have the generator model and serial number, fuel type, site address, displayed fault codes, and recent maintenance history ready if available. Tell us whether the generator failed during an outage, a scheduled exercise, or a test. Identify a facility contact who can discuss site access and operating restrictions.
Diagnosis, Repair Plan, and Operating Checks
We inspect the reported fault and explain the proposed repair and parts requirements. Timing depends on the diagnosis, equipment access, and parts availability. After repair, we discuss appropriate operating checks and whether testing under load would help confirm performance.

A load bank places controlled electrical demand on a generator so you can observe its performance beyond an unloaded startup. Testing can help reveal problems that appear only as demand increases, including changes in voltage, frequency, temperature, or engine operation.
WB Engine Repair offers mobile generator load bank testing for qualifying generators rated up to 200 kW. We can discuss whether load bank testing fits your generator and coordinate a testing window with the person responsible for facility operations.
WB Engine Repair brings more than 25 years of diesel mechanic experience and Cummins engine knowledge to generator work. We are a Cummins Onan Generator Authorized Dealer, supporting generator diagnosis, repair, and replacement discussions.
Most of our work is mobile, which can make on-site assessment practical for installed equipment. Our Kearns shop provides another option by appointment only when the generator and repair needs suit shop service.

The cost and timing of a backup generator repair depend on the fault, diagnostic work, parts, site access, and any testing required. We discuss the proposed work after assessing the equipment rather than assigning a flat price to an unknown failure.
Generator repair financing is available, subject to credit approval and current terms. If extensive damage or parts availability makes replacement worth considering, we can also discuss Cummins standby generator options. A replacement discussion does not mean every fault requires a new generator.
WB Engine Repair provides mobile generator repair throughout Utah, including Salt Lake County and rural facilities. We also travel to qualifying locations in Idaho and Wyoming; contact us to discuss availability for your site.
For a facility visit, provide the site entrance, generator location, access restrictions, and a contact who can coordinate testing or a planned interruption. Our shop is at 5176 Liberator Dr, Unit 106A, Kearns, UT 84118, and accepts visits by appointment only.

Share the generator model and serial number, fuel type, site address, fault messages, and a description of when the problem occurs. Maintenance records and site access details are also helpful.
That depends on the diagnosed fault, parts availability, site access, and post-repair checks. We can discuss current scheduling when you call and provide a clearer repair plan after the assessment.
Pricing depends on the diagnostic scope, travel, labor, parts, and testing required. Contact us with the equipment details and symptoms to begin a repair quote. Ask us about current financing terms if you would like to explore that option.
Yes. We offer mobile load bank testing for qualifying generators rated up to 200 kW. Testing applies controlled demand and records the generator's response. We’ll confirm suitability and discuss the testing plan for your facility.
Mobile assessment is often practical for an installed facility generator because it stays at its operating site. Shop service may suit other equipment or repair needs. Call before disconnecting or transporting a generator; the Kearns shop is by appointment only.
Tell WB Engine Repair where your generator is located, what happened, and which faults or warnings you have seen. We’ll discuss service availability and the next step toward a diagnosis and repair plan.
