Overview
The Generac A0000267819 is the genuine carbon monoxide (CO) sensing module, version 2.5, used on Generac portable generators equipped with CO-sensing shutdown. The module monitors CO around the generator and signals the unit to shut down if levels build up, so a failed module can leave the generator unable to start or run. Generac catalogs it as MODULE CO PORTGEN V2.5.
Key features
- Genuine Generac OEM part, sold under Generac's own number A0000267819

Frequently asked questions
What does the A0000267819 module do?
It is the CO-sensing unit on Generac portable generators. It detects carbon monoxide building up around the generator and tells the unit to shut down.
Does it fit every Generac portable with CO shutdown?
No. It fits units that use the V2.5 module, not every portable with a CO sensor. Send us your model and serial number and we'll confirm the right part.
Does A0000267819 replace 10000036511?
Yes, it replaces module 10000036511, but that swap also needs adapter harness A0000641868, which is sold separately.
What is the difference between A0000267819 and A0000509466?
Both are version 2.5 CO modules. A0000509466 is the EFI version; A0000267819 is the standard portable-generator version. Check your parts list or ask us which one your unit uses.
Is this a genuine Generac part?
Yes. A0000267819 is Generac's own OEM part number, and it is a new genuine Generac module.
Where do I find my generator's model and serial number?
They are on the data label on the generator. Send both to us so we can match the correct CO module and any adapter you need.
