Generac error code 2098 is an error code that indicates that the generator's engine speed is too low. This can happen for a variety of reasons, but is typically caused by a problem with the generator's fuel system. When the engine speed is too low, the generator will not be able to produce enough power to run the equipment it is connected to. This can cause a variety of problems, including a loss of power to the equipment, an increase in noise from the equipment, and a decrease in the efficiency of the equipment.

1. Check the oil level and add oil if needed

If the oil level is low, the engine may not start or run properly. To check the oil level, follow these steps:

  1. Park the generator and turn off the engine.

  2. Remove the oil cap.

  3. Check the oil level with a level indicator. Add oil if needed.

  4. Replace the oil cap. If the engine does not start or run properly, the cause may be a broken or clogged oil filter. To check the oil filter, follow these steps:

  5. Park the generator and turn off the engine.

  6. Remove the oil filter.

  7. Inspect the filter for cracks, tears, or other damage. If the filter is damaged, replace it.

  8. Replace the oil filter.

2. Clean or replace the spark plugs

  1. Remove the negative battery cable.
  2. Remove the fuel tank.
  3. Remove the air cleaner assembly.
  4. Remove the spark plugs.
  5. Clean the electrodes and the threads of the plugs.
  6. Install the plugs.
  7. Replace the air cleaner assembly.
  8. Replace the fuel tank.
  9. Reconnect the negative battery cable.

3. Check the air filter and clean or replace it if needed

  1. Open the cover on the side of the engine to access the air filter.
  2. Locate the air filter cover screws and remove them.
  3. Lift the air filter cover and remove it.
  4. Locate the air filter and clean or replace it as needed.
  5. Reinstall the air filter cover screws.

4. Check the fuel level and add fuel if needed

  1. Press and hold the power button on the generator until the generator stops.
  2. Disconnect the fuel line from the generator.
  3. Check the fuel level. If the fuel level is low, add fuel until the fuel level is at the "Full" line on the fuel gauge.
  4. Reconnect the fuel line to the generator.
  5. Press and hold the power button on the generator until the generator starts.

Still not working? maybe try one of these options:

  1. Check for loose wires and tighten them if needed.
  2. Check for blockages in the exhaust system and remove them if needed.
  3. Call a qualified technician to service the generator.
