Frequently Asked Questions

What does an accumulator tank do in an RV refrigerator?

The accumulator tank sits between the evaporator and compressor in the refrigerant circuit. It collects any liquid refrigerant that didn't evaporate in the cooling coils and ensures only refrigerant vapor enters the compressor. This protects the compressor from liquid slugging, which can cause catastrophic damage. It also stores a small amount of refrigerant oil to ensure proper lubrication.

How do I know if my accumulator tank needs replacement?

Signs of a failing accumulator include inadequate cooling, compressor short-cycling, unusual noises from the compressor, frost buildup in unexpected areas, or visible damage/corrosion on the accumulator itself. If a technician has diagnosed a refrigerant leak or contamination in your system, the accumulator is often replaced as part of the repair to ensure system cleanliness.

Can I install this accumulator tank myself?

Installation requires EPA Section 608 certification for handling refrigerants. The process involves recovering existing refrigerant, cutting and brazing refrigerant lines, installing the new accumulator, pressure testing, evacuating the system, and recharging with the correct amount of refrigerant. This is not a DIY repair and should only be performed by a certified HVAC or RV refrigeration technician.

Will this fit my Dometic refrigerator model?

This accumulator is designed for Dometic CF and RC series portable and built-in refrigerators. To confirm compatibility, check your refrigerator's model number (usually found on a label inside the unit or on the exterior). If you have a CF or RC model number, this is likely the correct accumulator. For other Dometic series (RM, RMD, etc.), you'll need a different part number.
