Warranty Information

General Dometic Warranty Policy

This part is covered by a comprehensive two-year (2 yrs.) warranty against defects in material and workmanship at the time of sale and under normal use, available for reference HERE. Please note that after the first year of your warranty, any and all claims must be made directly through the manufacturer by the original purchaser. Raney's is unable to assist with warranty claims after the first year of service.

Please call 1-800-544-4881 for warranty assistance through Dometic.

This warranty covers labor, specified parts, and freight. All Dometic Products (except those specifically built for commercial use) are warranted only when installed per the Seller’s installation instructions on vehicles built to R.V.I.A. A119-2 and C.R.V.A. Z-240 Standards. This warranty does NOT cover conditions unrelated to the material and workmanship of the Dometic Product. Such unrelated conditions include, but are not limited to: (a) damage not reported within 10 days of ownership; (b) faulty installation or installation that does not comply with the Seller’s instructions or R.V.I.A. and C.R.V.A. standards, and any damage resulting from such; (c) damage or failure caused by installation of accessories not manufactured and marketed by the Seller or any non-Dometic parts that are installed as replacement parts; (d) the need for normal maintenance and any damage resulting from the failure to provide such maintenance; (e) failure to follow Seller’s instructions for use of this Dometic Product; (f) flame outage due to blow out or high altitude; (g) reduced performance due to high altitude; (h) radio frequency interference (RFI) or electromagnetic interference (EMI); (i) 12 VDC system chassis ground decay and corrosion; (j) puncture of foam cabinet or vacuum insulated panels after acknowledged receipt; (k) animal or insect infiltration which damages unit or inhibits performance; (l) any accident to, or misuse of, any part of the Dometic Product and any alteration by anyone other than the Seller or its authorized representative; and (m) normal wear.


Major components (cooling unit, LP gas valve, burner, burner housing, electronic display, electronic module, evaporator fins, foam integrity, frame, thermistor, spark probe, ignition wire, ice maker compressor, second absorption loop, display escutcheon, lower toe plate, humidity switch, frame heater mullion, ice maker mullion) are covered for labor, parts and freight for two years (2 yrs.) from date of purchase. All other components that fail must be reported within the first 90 days of ownership in order to receive warranty coverage for labor, parts and freight.

The Original Purchaser must provide preventative maintenance on a yearly basis, beginning at the first anniversary of the date of purchase. The Original Purchaser must keep a record of the preventative maintenance to keep the warranty in effect. Failure of the Original Purchaser in providing this annual maintenance may void the warranty. The preventative maintenance must be performed at a Dometic Authorized Service Center/Dealer. The required preventative maintenance is an inspection, cleaning and full diagnostics performed on the entire electronic system, burner assembly, wiring and cooling unit. A copy of the receipt covering the maintenance checks must accompany the warranty claim during the second year of ownership. The cost of this preventative maintenance is the Original Purchaser’s responsibility and the preventative maintenance should take about one hour.


In order to obtain the benefits of this warranty, the Original Purchaser has the following two options:

  • Preferred: Deliver the Dometic Product for inspection to the nearest Authorized Dometic Service Center during the warranty period. To obtain the location of the nearest Authorized Dometic Service Center, refer to Dometic's Dealer Finder. The Authorized Dometic Service Center will work with Dometic to obtain warranty coverage if a seller defect is identified.
  • If it is not feasible under the circumstances to deliver the Dometic Product to an Authorized Dometic Service Center, please call 1-800-544-4881 for additional warranty assistance.
