A generator problem is an issue that can occur in both portable and standby generators, hindering their ability to provide backup power when needed. Some common generator problems include battery failure, overheating, fuel system issues, starter motor malfunction, and ATS failure. These issues can lead to costly repairs or even a complete generator failure if not properly addressed.
Understanding the most common generator issues and how to address them can save you costly repairs and potential downtime. Below are five common generator problems, along with practical, fact-based tips for resolving them safely and effectively.
5 Key Elements of a Generator Problem and Solution
1. Battery Failure
-
The Problem: Batteries can fail due to corrosion, age, or insufficient charge, leaving your generator unable to start.
-
The Fix:
-
Check battery voltage with a multimeter (healthy battery = 12.4–12.7 volts).
-
Clean corroded terminals.
-
Tighten any loose connections and consider replacing the battery if necessary.
-
2. Low Coolant or Overheating
-
The Problem: Low coolant or coolant leaks can cause the generator to overheat and shut down.
-
The Fix:
-
Top off coolant levels and inspect for leaks in hoses and the radiator.
-
Ensure the radiator is clean and free of obstructions to maintain proper airflow.
-
3. Fuel System Issues
-
The Problem: Stale fuel, clogged filters, or microbial growth in diesel generators can clog the fuel system.
-
The Fix:
-
Replace old fuel with fresh gasoline or diesel.
-
Add a fuel stabilizer if the generator will remain idle for an extended period.
-
Clean or replace fuel filters and inspect for air or water contamination.
-
4. Starter Motor Malfunction
-
The Problem: A faulty starter motor can prevent the generator from starting, often leading to only a clicking sound.
-
The Fix:
-
Ensure the battery is fully charged.
-
If the battery is fine but the generator doesn’t start, the starter motor might need to be inspected or replaced by a professional.
-
5. Automatic Transfer Switch (ATS) Failure
-
The Problem: The ATS fails to detect power outages or fail to send a signal to the generator to start.
-
The Fix:
-
Inspect the ATS for tripped breakers or blown fuses.
-
Check that power is properly reaching the ATS and, if needed, call a technician to test and repair the transfer switch.
