Generac generators have earned trust worldwide for their reliability. However, like all machines, they might sometimes face issues. Knowledge of these problems and their solutions ensures that your generator remains in peak condition. In this guide, we’ll delve into common error codes for Air Cooled Generac generators and how to address them.
1. Overcrank 1100: A Common Fuel Issue
Cause: The primary culprit is often insufficient fuel or fuel delivery complications. Fluctuations in temperature can cause Maxitrol regulators to produce excessive gas pressure, obstructing fuel flow. Additionally, if an outdoor regulator has the wrong brass vent cap, it can get blocked, disrupting proper fuel venting or even accumulating water that can freeze. Refer to the provided images to differentiate between the incorrect brass vent and the correct blue plastic vent. Notably, these regulators, even with the right vent caps, frequently pose problems with air-cooled generators and warrant replacement.
Fix: It’s advisable to consult a professional to replace the Maxitrol regulator. For immediate relief, reset the generator, activate the manual mode, or release extra gas. Regularly check your air filter’s cleanliness and ensure the choke is operational.
2. Charger Missing AC: Generator Shutdown Alerts
Cause: During power outages, turning off the generator for tasks like checking the oil can trigger this warning.
Fix: Always remove the generator’s fuse when turning it off to conserve fuel see our other article about this process. Otherwise, the battery might drain. If this warning appears under different conditions, consult an expert for an inspection.
3. 1505 RPM Sensor Error: Battery or Starter Issues
Cause: This error often points to a faulty battery or starter. A blank screen on attempting to start indicates a battery problem.
Fix: Update the generator’s controller firmware with the help of a certified technician. Before considering a starter replacement, always check and, if necessary, update the firmware.
4. 2800 Auxiliary Shutdown: Accidental Switch Engagement
Error Code 2800 Auxiliary Shutdown Switch locations on Rear Outside and Inside of Generac Air Cooled backup generators
Cause: Accidentally pressing one of two auxiliary shutdown switches often triggers this error.
Fix: Identify the pressed switch, reset it, then sequentially press the off, enter, and auto buttons. A green light should appear, confirming the error’s clearance.
5. 1400 High Temperature: Overheating Concerns
Cause: Overheating in extremely hot conditions can trigger this warning.
Fix: Ensure the generator has proper ventilation and remains free from obstructions. Keep the louvers clean and avoid operating the generator with its top hatch open, unless briefly for diagnostic testing.
6. Alarm 1300 Low Oil Pressure: Oil Level & Pressure Woes
Cause: Either the generator has a low oil level or faces more serious problems.
Fix: Check the oil level first. If the problem persists, consult a certified Generac technician to inspect the oil pressure sensor and the generator’s overall oil pressure.
7. 2100 Overload: Handling Overburdened Generators
Cause: Overburdening due to increased load or a malfunctioning load shedding device can result in this error.
Fix: During power outages, minimize heavy loads. Turn off larger breakers in your panel and gradually reintroduce loads to determine the root cause.
