Preventing Generac Fault Codes

To prevent Generac fault codes, it is important to perform regular maintenance and operate the generator properly.

Regular Maintenance

Performing regular maintenance on your Generac generator can help prevent fault codes from occurring.

Here are some maintenance tasks to consider:

  • Oil and filter changes: Regular oil and filter changes are essential to keeping your generator running smoothly. Refer to your owner’s manual or this helpful guide for recommended intervals and oil types.
  • Air filter replacement: A dirty air filter can reduce your generator’s performance and cause it to overheat. Replace the air filter according to the manufacturer’s recommendations.
  • Spark plug replacement: Worn or dirty spark plugs can cause your generator to misfire or fail to start. Replace the spark plugs according to the manufacturer’s recommendations.
  • Fuel system maintenance: Keep your fuel system clean and free of debris by using fresh fuel and adding a fuel stabilizer. Check the fuel filter and fuel lines for signs of wear or damage.

Performing these maintenance tasks regularly can help keep your Generac generator running smoothly and prevent fault codes from occurring.

Proper Operation

Proper operation of your Generac generator can also help prevent fault codes from occurring. Here are some tips to keep in mind:

  • Start the generator regularly: Starting your generator regularly (even if you don’t need it) can help keep it in good working order. This can also help prevent issues with stale fuel. You can also decides to set up the exercise timer if you are using a Generac standby generator.
  • Don’t overload the generator. Overloading your generator can cause it to overheat and trigger a fault code. Make sure you know the wattage requirements of the appliances you’re powering and don’t exceed the generator’s capacity.
  • Don’t run the generator in an enclosed space. Running your generator in an enclosed space (such as a garage or basement) can cause carbon monoxide poisoning. Always operate your generator outdoors in a well-ventilated area.
