Fix Error Code 1902 On Generac

To fix Generac error code 1902 you can verify voltage output, check fuel supply, and verify gas pressure.

1. Verify Voltage Output

Checking the voltage output is a crucial diagnostic step to identify if low voltage is the cause of Error Code 1902 on your Generac generator.

  • Turn off the generator and ensure it is not operating.
  • Set your digital multimeter to AC or DC voltage as required.
  • Connect the multimeter probes to the corresponding generator output ports.
  • Read the voltage measurement and compare it to the expected output.
  • If the voltage is below the rated output, it may indicate an issue with the generator’s voltage regulator or another component that requires attention.

2. Check Fuel Supply

Low fuel supply can lead to insufficient power generation, triggering Error Code 1902. Ensuring an adequate fuel supply is crucial for the generator to produce the required voltage consistently.

  • Check the fuel level in the generator’s tank.
  • If the fuel level is low, refill the tank with the appropriate fuel.
  • Restart the generator and monitor for the error code.

3. Verify Gas Pressure

In cases where the generator is powered by natural gas, low gas pressure can result in inadequate power generation, leading to Error Code 1902. Verifying and adjusting the gas pressure can help resolve this issue.

  • Use a gas pressure gauge to measure the gas pressure supplied to the generator.
  • If the gas pressure is below the required level, consult a qualified technician to adjust the gas supply accordingly.
  • Restart the generator and check for the error code.
