Frequently Asked Questions
What is a Customer Replaceable Unit (CRU)?
A CRU is a factory-sealed cooling system module that replaces the absorption cooling unit in your Dometic refrigerator. It contains the boiler, condenser, evaporator, and pre-charged refrigerant in one complete assembly. This allows repair of a failed cooling system without replacing the entire refrigerator cabinet, door, and controls.
Can I install this CRU myself?
While called a "Customer Replaceable Unit," CRU installation requires technical knowledge of RV refrigeration systems, proper handling of sealed cooling components, and following Dometic's specific installation procedures. Most RV owners choose to have a qualified RV technician perform the installation to ensure proper function and avoid warranty issues.
How do I know if my refrigerator needs a CRU replacement?
Common signs include complete loss of cooling in both freezer and refrigerator compartments, yellow residue or ammonia smell around the cooling unit, or visible corrosion on the cooling coils. If your refrigerator runs but doesn't cool, and you've ruled out thermostat, power supply, and ventilation issues, the cooling system may have failed and require CRU replacement.
Is this CRU compatible with my specific Dometic model?
This CRU is designed for specific USA-model Dometic refrigerators. To verify compatibility, you'll need your refrigerator's model number and serial number (found on the data plate inside the refrigerator). Contact our parts specialists with this information to confirm this CRU matches your unit before ordering.
