TJ90SUD111 Filter Drier – Copper Refrigeration Replacement

Product Description
Maintain optimum performance of your refrigeration system with the genuine filter drier part number TJ90SUD111. This copper-line drier is designed to remove moisture and contaminants from the refrigerant line, protecting the compressor and expansion valve from damage and helping ensure efficient operation. Repair Clinic+1 Because sealed-system components vary by refrigerant type, tubing size, and system design, please check with your maintenance technician prior to ordering to confirm compatibility with your specific appliance or refrigeration system. appliancerepair.homedepot.com

Features & Benefits

• OEM-equivalent copper construction: Built to meet the rigorous demands of sealed refrigeration systems with moisture and particle removal capability. appliancepartspros.com+1

• Improves system reliability: By filtering moisture and debris, it helps safeguard key components like the compressor and expansion device—reducing risk of system failure.

• Cost-effective maintenance: Replacing this drier can prevent larger, costly sealed-system repairs or early component failure. Repair Clinic

• Standardised sizing & connections: Fits many systems with ¼" O.D. flare/copper connections in residential or light commercial refrigeration/air-conditioning loops. picclick.com+1

Common Symptoms That Indicate Replacement Is Needed

• The refrigeration system shows poor cooling performance or high head-pressure despite compressor, condenser and fan being functional. Repair Clinic+1

• Moisture-related issues: frost or ice formation in unexpected places, or unusual freeze-ups in the suction or liquid lines.

• Technician replacement scenario: sealed-system repair done (e.g., compressor change) but the drier was not replaced—failure risk increases. Repair Clinic

• Visible corrosion, discoloration or bulging on the existing drier canister—indicating saturation or contamination.

Cross Reference / Alternate Part Numbers

  Always check your existing part number and system specifications to confirm match.

Compatibility Notes

• Ensure your system uses the same connection size (typically ¼" O.D. copper) and matches mounting length/diameter of the drier. picclick.com

• Replacement of the drier alone does not fix underlying issues like refrigerant leaks, compressor failure or condenser airflow problems—if these are present you should have your technician inspect the entire sealed system.

• Because installing a drier involves refrigerant handling and sealed-system access, it is strongly recommended that a qualified technician perform the service.

• After installation, ensure the system is properly evacuated and charged according to manufacturer specifications; failure to do so may lead to premature failure of the drier or other components.

• While the drier improves system health and longevity, it does not address unrelated appliance issues such as door seal failures, mechanical wear, or refrigerant level problems.
