Compatibility and Buyer Check
Before ordering, confirm that your system is a Jandy AquaPure COM25 and that your service manual calls for part number AZ006. This part should be matched by the part number, wire color, and assembly position, not by image alone.
If your system needs the opposite-side SCR assembly, compare this part with the Zodiac AZ007 right SCR assembly with orange wire before purchasing. If you are also checking related electrical parts in the same COM25 system, review the Zodiac R0461700 gold resistor assembly.
What This Left SCR Assembly Does
The left SCR assembly is part of the electrical control area inside a compatible AquaPure COM25 salt water chlorine generator. It helps support the system’s power-control function as part of the generator’s internal electrical setup.
Replacing the left SCR assembly may help when this specific part has failed or shows visible damage. It will not fix every salt system issue. Low chlorine output, no power, warning lights, or system errors may also come from the cell, wiring, power cord, control board, salt level, or water flow.
Before You Order
Check these details before purchasing:
- Confirm the exact part number AZ006.
- Verify that your system is a Jandy AquaPure COM25 model.
- Match the yellow wire and left-side assembly position with the original part.
- Inspect nearby wiring, terminals, and the resistor assembly for damage.
- Check whether the issue is with the SCR assembly, power cord, control area, or salt cell.
- If the power cord is damaged, compare the Zodiac R0402800 16 feet DC power cord replacement and Zodiac R0402700 8 feet DC power cord replacement before ordering the SCR assembly.
- If you are servicing the power supply cover area, the Zodiac R5000100 power supply cover support bracket may also be useful.
Installation Notes
Turn off power to the salt water chlorine generator and pool equipment before opening the control area or touching any electrical part. This type of repair should be completed by a qualified pool technician or electrician if you are not experienced with pool equipment wiring.
Before removing the old assembly, take clear photos of the wiring and mounting position. Install the replacement in the same location and orientation as the original left SCR assembly. Do not force connectors, reuse damaged terminals, or operate the system if wiring looks burned, loose, or corroded.
After installation, restore power only after all connections are secure and the control area is properly closed.
Maintenance and Troubleshooting Tips
To help protect the replacement part:
- Keep the control area dry and protected from moisture.
- Inspect wires and terminals during service.
- Do not ignore burned marks, loose connections, or corrosion.
- Maintain proper salt level and balanced pool water.
- Check the salt cell and power cord before replacing multiple electrical parts.
- Follow the Jandy/Zodiac service manual for diagnostic steps.
