• Generac RV Generators FAQ

Q: Where can I purchase parts?

A: Parts can be purchased through our online store with fast free shipping.

Q: Where can I find a Generac RV service dealer in the U.S. or Canada?

A: To locate a dealer near you call our Automated Service Dealer Locator at 888-GENERAC (U.S. locations only) .

Q: How do I obtain the maintenance items that I'll need to perform routine service on my Generac RV
generator?

A: A convenient preventative maintenance kit is available which contains the necessary items for routine service. These can be obtained from any Authorized Service Dealer. Refer to your owner's manual for procedures and schedules. All RV generators feature single-side serviceability with all routine maintenance points positioned up front for easy access.

Q: I can't find my original Generac RV generator owner's manual. How can I get another copy?

A: For our customer's convenience, we now offer technical information, diagnostic repair, installation and owner's manuals online. Please refer to the owner's manual section for this information.

Q: What type of oil should I use?

A: Use only high quality detergent oil rated with American Petroleum Institute (API) Service Classification SG, SH or SJ. DO NOT USE special additives. Petroleum-based detergent oils help to keep the engine clean and prevent the formation of gum and varnish deposits. Synthetic oil may be used only after the recommend break in period.

Q: My owner's manual recommends running the generator weekly. Why is this necessary?

A: Performing a weekly “exercise” of the generator is necessary to promote engine and alternator longevity. Generac recommends that you start and operate the generator at least once every seven days. To exercise, start the generator, turn on a few appliances and let the generator run for at least 30 minutes. This lubricates internal parts and helps to eliminate any condensation that may have built up in the alternator.

Q: Where do I go to have warranty repairs performed?

A: Any Authorized Service Center can perform warranty service. To locate a dealer near you call our Automated Dealer Locator at 888-GENERAC, available 24/7/365. Our Authorized Service Centers provide parts, service and information on Generac RV equipment, regardless of where it was purchased. Authorized Service Centers are staffed with trained technicians certified in supporting all aspects of the entire RV generator line.

Q: Is my warranty transferable?

A: New RV generators purchased by the original owner will have a 3-year transferable limited warranty. This transferable limited warranty is in effect only if the original owner has properly submitted a product registration form to Generac. For subsequent owners, the 3-year limited warranty begins at the original date of purchase and requires submission of an additional warranty registration form to Generac.

Q: My generator starts hard. What could be the cause?

A: The most common problem associated with hard starting on a gasoline unit is stale fuel. Fuel stabilizers should be used to extend fuel life. On a liquid propane (LP) unit, the most common problem is insufficient LP at the generator regulator ― eleven inches of water column is needed.

Q: I’m having problems with my RV generator. What should I do first?

A: Refer to the troubleshooting guide in your owner's manual.

Q: Is my RV generator capable of producing 240 Volts?

A: Yes. The PRIMEPACT Series generators can be reconfigured to 240 volts. Only a certified dealer should make this modification. Improper configuration can damage the generator or on-board appliances.

Q: Can my computer and other electronic equipment be used while operating my RV generator?

A: Yes. Generac offers models from 3.4 kW to 8.5 kW, which are compatible with all electronic devices, including computers.

Q: What about emissions regulations? Do I need to "de-carbonize" the engine periodically?

A: No. Generac uses overhead valve, industrial-grade engines in its RV generators. They comply with all current emissions requirements. Unlike other generator engines, there is no need to overhaul the engine to remove carbon.
