Common GenTrax Generator Issues & Quick Fixes

GenTrax generators are a reliable choice for caravanning, camping, and backup power. Like any engine-driven appliance, they may occasionally experience issues. This guide covers the most common GenTrax generator problems and the quick fixes you can try before seeking professional help.

1. Generator Won’t Start

Possible Causes:

• Low or no fuel

• Choke not engaged (for cold starts)

• Old or stale fuel

• Spark plug issues

• Low oil level (safety cut-off engaged)

Quick Fixes:

• Check fuel tank is filled with clean, fresh unleaded petrol.

• For cold starts, engage the choke before pulling the starter cord.

• Replace fuel if it’s older than 30 days.

• Inspect and clean spark plug; replace if worn or damaged.

• Check oil level—GenTrax generators have a low-oil sensor that prevents starting if oil is low.

2. Generator Starts but Cuts Out

Possible Causes:

• Overloaded output (too many appliances connected)

• Fuel blockage or dirty carburettor

• Clogged air filter

• Low oil level triggering shut-off

Quick Fixes:

• Reduce the load by unplugging some appliances.

• Check and clean air filter.

• Inspect fuel line for blockages; clean carburettor if necessary.

• Refill engine oil if low.

3. No Power Output

Possible Causes:

• Circuit breaker tripped

• Overloaded or faulty appliance connected

• Internal alternator issue

Quick Fixes:

• Reset the generator’s circuit breaker and try again.

• Disconnect all devices, then reconnect one at a time.

• If no output after reset, seek professional servicing.

4. Generator Runs Rough or Surges

Possible Causes:

• Old or contaminated fuel

• Carburettor jets blocked

• Dirty spark plug

• Low-quality fuel

Quick Fixes:

• Drain and replace with fresh fuel.

• Clean carburettor and jets.

• Clean or replace spark plug.

• Always use fresh, high-quality unleaded petrol.

5. Generator is Too Noisy

Possible Causes:

• Loose bolts or panels

• Poor placement (hard surfaces amplify vibration)

• Exhaust system issue

Quick Fixes:

• Tighten all exterior bolts and screws.

• Place generator on a rubber mat or grassy surface to reduce vibration noise.

• Check exhaust and muffler for leaks.

6. Overheating Issues

Possible Causes:

• Blocked air vents

• Overloaded generator

• High ambient temperatures

Quick Fixes:

• Ensure the generator is in a well-ventilated area (never indoors).

• Reduce load to within rated capacity.

• Clean vents and remove any obstructions.

Maintenance Tips to Prevent Problems

• Run the generator at least once a month to keep fuel fresh and parts lubricated.

• Change engine oil every 20–50 hours of use, depending on conditions.

• Replace spark plugs and clean the air filter regularly.

• Use a fuel stabiliser if storing the generator for extended periods.

Key Takeaways

• Most GenTrax generator issues can be solved with simple checks: fuel, oil, spark plug, and load management.

• Preventative maintenance is the best way to avoid costly repairs.

• Always use fresh fuel and keep your generator clean and ventilated.
