How Do You Troubleshoot a Generac Generator?

To troubleshoot a Generac generator, first identify the specific problem and symptoms associated with it. Common problems with a Generac generator include failure to start and lack of electrical power. Other problems include failure of the light indicator, failure of the exhaust and corrosion in the wire lines.

A Generac generator may fail to start up when the on/off switch is in the “off” position, the battery is defective, a low level of gas is in the fuel tank or when the spark plug is worn out. To resolve this, turn the on/off switch into the “on” position, replace the battery and the spark plug and fill the fuel tank. An incorrect fuel mix in the engine, presence of water in the fuel tank or a faulty intake valve can cause the engine to over-run. To rectify such issues, contact a Generic company technician.

A tripped circuit breaker can cause electrical power failure when the engine is running; replace the circuit breaker to stop the failure. Failure of the engine light caused by a defective start switch is resolved by replacing the faulty start switch. An oil fuel leak or a clogged vent can cause failure of the exhaust system to emit unwanted gases. For this issue, consult the manufacturer for a detailed description on where to look and don’t forget to clean the venting regularly. If rust and dirt particles have corroded the wire lines, clean the wire lines with an air pump.
