Dear Winnebago RV Owner,
When you purchased your new Winnebago RV, you also received our commitment to provide you with a
quality product and our dedication to continuing customer satisfaction. In keeping with this commitment, we are
notifying you of a service campaign that may affect your Winnebago RV.
Reason for This Campaign
On certain Winnebago View and Navion coaches, performing a hard reset of the Xantrex Inverter may change the
‘Battery Type’ setting. If the ‘Battery Type’ setting is incorrect the batteries may not charge properly, which can lead to
reduced performance.
What We Will Do
Winnebago Motorhomes has released Field Service Campaign 76-05 authorizing your dealer to update the Xantrex
inverter to ensure that a hard reset does not change the ‘Battery Type’ setting. As part of this campaign the inverter
firmware will also be updated to the latest version.
What You Should Do
Please contact your authorized Winnebago motorhome dealer to schedule an appointment to have this repair
performed. The actual repair will take approximately 1.5 hours. However, due to service scheduling requirements,
your dealer may need your coach for a longer period of time.
To locate a Winnebago Motorhome dealer, please visit www.winnebago.com and click on the “Locate Dealer” link.
This remedy will be performed at no charge to you through December 11, 2026.
