Generator shuts down and displays E14 shortly after starting.

Safety first: Turn OFF the generator, disconnect battery negative, and allow the exhaust system to cool completely. Exhaust components can cause severe burns.

• Inspect exhaust outlet: Check that the exhaust pipe and muffler outlet are not blocked by nests, debris, or snow/ice. Clear any obstructions.
• Check air intake: Ensure louvers and intake grilles are clear. Replace a dirty air filter element with a Yamaha-approved filter.
• Verify load level: Confirm that the connected load does not exceed the generator's rated kW. Overloading can cause high exhaust temperatures.
• Inspect exhaust temperature sensor: Locate the sensor on the exhaust manifold or pipe. Check wiring and connector for heat damage. Replace the sensor if it tests out of specification.
• Reset and test: Clear E14 and run the generator under normal load while monitoring for recurrence.
