AGA5561EXT replacement

If your unit has a Tecumseh AGA5561EXT or AG133RT-003-J7 that has failed, this compressor is the current Tecumseh replacement. It keeps the same AG body, 5 ton capacity, 208-230 V three-phase power, 7/8″ suction and 1/2″ discharge connections.

Where the AG133RF-104-J7 compressor is used

This compressor is used as a direct replacement in 5 ton R-22 commercial and light commercial condensing units, packaged units and split-system heat pumps that run on 208-230 V three-phase power. It is a common choice when a failed compressor in an existing R-22 system needs to be replaced without replacing the whole unit. For 460 V equipment, use the Tecumseh AG133UF-104-J7.

How to install a replacement compressor

1. Confirm voltage, phase and line sizes match the nameplate of the old compressor.
2. Recover the refrigerant and find the cause of the failure (burnout, electrical, or liquid slugging).
3. Replace the liquid line filter drier, and add a suction line drier after a burnout.
4. Braze in the compressor with a nitrogen purge, then pressure test and evacuate to 500 microns or less.
5. Check three-phase rotation, charge to the unit’s specification and verify amps, superheat and subcooling.
