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:

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.
