      If your Generac Power Systems Lighting Equipment cranks but doesn't start, check the fuel level in the tank and verify the fuel pump operation. Inspect the air filter for any blockages. Also, ensure that the PAS (Programmable Automatic Start) is disengaged.

    Why does my Generac Power Systems MAGNUM MLT6SM have a high coolant temperature shutdown?
    • C
      Craig HughesAug 16, 2025
      A high coolant temperature shutdown in your Generac Power Systems Lighting Equipment can occur due to several reasons. The coolant level might be low, so add coolant if needed, after allowing the engine to cool. There could be a blockage in the radiator; inspect the radiator shroud and ducting, and remove any foreign matter. Another cause may be leakage in coolant hoses, the engine block, or the water pump; inspect for visible leaks and verify the tension of the water pump serpentine drive belt. Other potential causes are a faulty thermostat or water pump failure, which require contacting a GMP ASD to replace, or an incorrect coolant mix/frozen radiator; thaw the radiator and flush the coolant system with the correct coolant mixture.

    How to fix low oil pressure shutdown on Generac Power Systems Lighting Equipment?
    • J
      Joshua Wolfe MDAug 26, 2025
      A low oil pressure shutdown on your Generac Power Systems Lighting Equipment may be due to a low oil level. Verify the oil level on the dipstick and add oil if needed. It could also be caused by oil leaking from the engine, so inspect the engine for leaks. A third cause may be oil pressure switch failure. In that case, refer to the OEM engine operator’s manual to identify corrective action.
