Dometic 3-Ton AC Accumulator - Fits TK05505 Climate Control System - Part# 290333150
The Dometic 290333150 is a genuine OEM accumulator designed for 3-ton air conditioning systems in commercial vehicles and RVs. This critical refrigeration component removes moisture and debris from the refrigerant system while providing temporary refrigerant storage during the cooling cycle. If your Dometic TK05505 climate control system is experiencing reduced cooling performance, compressor short-cycling, or ice buildup on refrigerant lines, a failing accumulator is often the culprit. This replacement part restores proper system operation and protects your compressor from liquid refrigerant damage.

Frequently Asked Questions
Q: What are the signs that my AC accumulator needs replacement?
A: Common symptoms include reduced cooling capacity, frost or ice buildup on refrigerant lines, unusual hissing or gurgling sounds from the AC system, compressor short-cycling, and visible oil leaks around the accumulator. If your system was opened for repairs or has been in service for several years, the accumulator should be replaced as preventive maintenance.
Q: Can I reuse my old accumulator if it looks okay?
A: No. Accumulators contain desiccant material that absorbs moisture and becomes saturated over time. Once the system is opened to atmosphere, the desiccant immediately begins absorbing humidity and cannot be regenerated. Industry best practice requires accumulator replacement whenever the refrigerant system is opened for service or repair.
Q: Do I need to evacuate and recharge the system after installing this accumulator?
A: Yes. Accumulator replacement requires recovering the existing refrigerant, installing the new accumulator, evacuating the system to remove air and moisture, and recharging with the proper refrigerant type and quantity. This work should be performed by a qualified HVAC technician with appropriate EPA certification and recovery equipment.
Q: Is this accumulator pre-charged with refrigerant?
A: No. This accumulator ships empty and must be installed into your existing system, which will then be evacuated and recharged by a qualified technician. The internal desiccant is factory-sealed to prevent moisture contamination before installation.
