Controller displays E19, generator shuts down with high exhaust temperature warning

Safety first: Turn controller to OFF, open the generator AC breaker, and allow the exhaust system to cool completely before touching it.

• Inspect exhaust outlet: Ensure the exhaust termination is not blocked by snow, ice, vegetation, or animal nests. Clear any obstructions.
• Check muffler and piping: Look for crushed sections of exhaust pipe, severe rust, or signs of internal collapse in the muffler.
• Verify clearances: Confirm that the generator is installed with proper clearance from walls and structures so exhaust can dissipate.
• Inspect exhaust temperature sensor: Locate the sensor on or near the exhaust manifold. Check wiring and connector for heat damage or disconnection.
• Replace sensor if faulty: If wiring is intact but E19 recurs with normal exhaust flow, replace the exhaust temperature sensor.

Do not operate the generator with a restricted exhaust; this can cause carbon monoxide buildup and engine damage.
