Recalls filed by Monaco
Equipment #03V166000 · 2003 · 0 units
Problem: On certain motorhomes, fifth wheels and travel trailers equipped with norcold refrigerator cooling units model numbers 1200lr and 1200rim, these refrigerators can experience low cycle fatigue failure which can lead to the liquid solution slowly leaking from the sealed, pressurized cooling unit through a small crack.
Risk: If a leak occurs and the unit is continually operated, hydrogen gas may be expelled and can be ignited, resulting in a fire, possibly causing serious injury or death.
Fix: Norcold will notify its customers and provide a replacement cooling unit free of charge. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact norcold service center at 1-800-667-3005 or Monaco at 574-862-7211.
Equipment #03V386000 · 2003 · 888 units
Problem: On certain motor homes, the federal identification tag on both 36' and 38' models was incorrect. The initial tag shows the psi as 90 lbs. Front and 100 lbs. Rear. The correct psi is 105 front and 115 rear. Also, the federal identification tag on certain units incorrectly states that the unit was built with a tag axle.
Risk: Driving the motor home with under/over inflated tires can cause or contribute to premature tire failure, possibly resulting in a sudden blowout or other failure that could result in the loss of control of the motor home.
Fix: Owners will be provided with a correct federal identification tag and installation instructions. Owner notification began October 24, 2003. Owners should contact Monaco at 1-800-685-6545.
Equipment #08V257000 · 2008 · 8,587 units
Problem: Monaco is recalling certain motor homes equipped with norcold refrigerators. A fatigue failure in the section of the cooling unit which contains the refrigerant could allow the liquid solution to slowly leak.
Risk: Extended operation of a leaking cooling unit could lead to a fire from gas which might escape.
Fix: Monaco is working with norcold to repair these refrigerators. Norcold will provide thermal switch kits to owners along with the necessary forms and instructions. The recall began on August 29, 2008. Owners may contact norcold at 1-800-767-9101 or Monaco at 1-800-685-6545.
