Common Problems with Generators
Lawn mowers experience a range of issues over time, especially with regular seasonal use. Understanding these problems helps identify when repair is needed.
Generator will not start
The engine may not crank, may crank without firing, or may start for one second and immediately die. Common causes include stale fuel, clogged carburetor jets, a weak battery, bad spark plug, low oil sensor issues, starter failure, or blocked fuel lines.
Starts then shuts off
The engine may run for a few seconds, a few minutes, or only while the choke is partly engaged. This can happen when the carburetor is dirty, the fuel filter is restricted, the fuel pump is weak, the oil level is low, or the generator is overheating or sensing an overload.
Generator runs rough
A rough running generator may surge, shake, sputter, backfire, or struggle when a load is added. This is often caused by poor fuel quality, dirty carburetor passages, weak spark, restricted air flow, or old maintenance parts, especially after long storage.
Runs but produces no power
The engine sounds fine, but the outlets are dead or the voltage is unstable. Possible causes include tripped breakers, voltage regulator failure, alternator problems, rotor or stator issues, damaged outlets, wiring faults, bad brushes, or transfer switch trouble.
RV generator problems
RV generators sit for long periods, run in enclosed compartments, and depend on the RV battery and fuel system. Onan and Cummins Onan units commonly develop hard starting, stalling, rough running, low power output, and clogged carburetors when not exercised regularly.
Standby and leak concerns
A standby generator may fail to start, fail an exercise cycle, show a control error, or fail to transfer power because of battery failure, transfer switch issues, or fuel supply concerns. Fuel and oil leaks from cracked lines, loose clamps, or worn gaskets should be checked quickly.
Causes of These Problems
Generator problems usually develop for a reason. Many are caused by storage, fuel condition, Cheyenne weather exposure, heavy use, or skipped maintenance.
Stale or contaminated fuel
Many generators sit unused for long periods. Gasoline degrades and leaves deposits inside the fuel system that clog carburetors, fuel lines, filters, and jets. The generator may refuse to start, surge, stall, or run only with the choke engaged.
Dirty carburetor
The carburetor controls the air and fuel mixture. When small passages become restricted, the generator may run lean, stall, surge, or fail to start. Cleaning or repair can often restore performance if no other internal damage exists.
Weak battery
Standby and RV generators rely on a battery to start. Cheyenne cold starts and weather exposure make weak battery problems more noticeable, causing slow cranking, clicking sounds, control panel errors, or complete failure to start.
Low oil shutdown
Many generators include low oil protection. If the oil level is too low, the generator may stop running or refuse to start. Sometimes the sensor itself malfunctions and shuts the unit down even when oil appears correct.
Overload and electrical failure
Too many connected appliances can trip breakers, bog the engine down, overheat components, or produce low voltage. Even if the engine runs well, the alternator, stator, rotor, voltage regulator, control board, or transfer switch can fail.
Weather, storage, and missed maintenance
Cold starts, dust, wind, moisture, and long storage affect fuel quality, batteries, wiring, and filters. Skipped oil changes, dirty filters, and worn spark plugs make the unit harder to start and more likely to fail under load.
Our Repair Process
Our generator repair process is designed to be clear, practical, and convenient for Cheyenne customers, focused on finding the real cause of the problem.
On site inspection
We inspect the generator at your location, checking the fuel system, oil level, battery, wiring, controls, filters, and outlets, plus signs of leaks, loose connections, blocked air flow, corrosion, old fuel, and improper storage.
Diagnosis
We test spark, fuel flow, carburetor function, battery strength, starter operation, voltage output, breaker function, and transfer switch response. Many generator symptoms overlap, so testing prevents guesswork and unnecessary parts.
Repair and testing
Repairs may include carburetor cleaning, spark plug replacement, filter replacement, fuel system repair, battery service, starter repair, wiring checks, and leak repair. The generator is then tested to confirm it starts, runs smoothly, and produces usable power.
