Briggs & Stratton Storm Responder 6250W Portable Generator MECH-GFCI Error Fix: GFCI Outlet Trips Repeatedly

Error code MECH-GFCI on the Briggs & Stratton Storm Responder 6250W Portable Generator means: GFCI Outlet Trips Repeatedly. The GFCI-protected outlets on the generator trip immediately or frequently during use. GFCI (Ground Fault Circuit Interrupter) outlets detect current leakage to ground and shut off power to prevent electrocution. Moisture in extension cords, damaged cord insulation, or faulty connected equipment can cause GFCI tripping. Using a long extension cord in wet conditions is a common cause. Check all cords for damage. Try connecting a known-good load directly to the generator to isolate the problem. The GFCI mechanism itself can fail — test by pressing the TEST button, then RESET. On newer generators, GFCI outlets are required by safety standards on all 120V receptacles.
