Error codes and troubleshooting

Code	Meaning	What to do	Manual page
RED light blinks	The generator shut off because carbon monoxide is accumulating around it. The red light on the side panel badge blinks to show this CO shut-off.	Follow all safety instructions and relocate the generator to an open area outside, far away from windows, doors and vents.	22
YELLOW light blinks	The generator shut off because of a CO PROTECT system fault. The yellow light on the side panel badge blinks to show the fault.	Start the generator to confirm the yellow light blinks when it shuts off. If CO PROTECT keeps faulting and shutting off, contact an Independent Authorized Service Dealer (IASD). Call service if it persists.	22

FAQ

How long does the Generac iQ5200 run on a tank?

The maker rates it at 9 hours at 50 % load (about 1,950 W) on a 3.2-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.

Can the Generac iQ5200 start a sump pump or well pump?

Starting surge matters more than running watts: this unit is rated 5200 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
