Essential electronic control box for GE RVAC systems. EZ Install ceiling-mount design enables hands-free electrical connections. Required for all electronic installations.
The GE RGREC3A is a genuine GE Appliances main electronic control unit designed specifically for RVAC (RV Air Conditioner) systems. This essential control box features the innovative "EZ Install" design that allows air conditioner controls to be mounted directly to the ceiling assembly, creating a hands-free electrical connection installation that simplifies the wiring process and reduces installation time and complexity.
Required for all electronic control installations, the RGREC3A serves as the communication hub between your rooftop AC unit, ceiling assembly, and wall thermostat. This control unit manages all system functions including temperature regulation, fan speed control, and diagnostic feedback. Compatible with GE's newer R32 refrigerant-based RVAC models (GRC, GRH, PLC, and PLH series), the RGREC3A replaces the older RARMC2A control unit and provides enhanced cooling efficiency and reliable performance for single-zone RV air conditioning systems.

If you have an older ARC, ARH, PLH series air conditioner with R410A refrigerant: You MUST also purchase adapter harness WJ35X35673 to use this control unit. The adapter converts the electrical connections from older 6-pin plugs to the newer 3-pin and 4-pin configuration required by the RGREC3A control box.
This Package Includes: • (1) RGREC3A Electronic Control Unit • Mounting Hardware • Installation Instructions Weight: 3 lbs NOT Included (Required for Complete System): • Wall Thermostat (RGRWT2B or RGRWT2W - required) • Ceiling Assembly (RGRED1A or RGREN1A - required) • Adapter Harness WJ35X35673 (required for older ARC/ARH models only) Complete System Kits Available: • RVACS-DKITB/W: Ducted kit with ceiling assembly, control unit, and thermostat • RVACS-NKITB/W: Non-ducted kit with ceiling assembly, control unit, and thermostat
What The RGREC3A Control Unit Does: The RGREC3A is the electronic brain of your RVAC system, managing communication between three key components: 1. Rooftop AC Unit: Receives power and control signals from the control box 2. Ceiling Assembly: Interfaces directly with control unit via EZ Install design 3. Wall Thermostat: User interface that sends temperature and fan speed commands to control unit The control unit processes thermostat inputs, manages compressor and fan operation, monitors system performance, and provides diagnostic feedback when issues occur. This centralized control design simplifies troubleshooting and enables more sophisticated climate control features than older analog systems. EZ Install Ceiling-Mount Design Benefits: Traditional RV air conditioner installations required complex hand-wiring of multiple electrical connections between the rooftop unit, interior controls, and thermostat. The RGREC3A's EZ Install design revolutionizes this process by: • Mounting directly to the ceiling assembly with integrated connectors • Eliminating hand-wiring between control box and ceiling assembly • Reducing installation time and potential wiring errors • Creating a clean, integrated appearance inside the RV • Simplifying future service and replacement Installation Overview: 1. Install rooftop AC unit (GRC, GRH, PLC, or PLH series) per manufacturer instructions 2. Install ceiling assembly (RGRED1A ducted or RGREN1A non-ducted) in desired interior location 3. Mount RGREC3A control unit to ceiling assembly using EZ Install mounting system 4. Connect control unit to rooftop AC unit wiring 5. Install wall thermostat (RGRWT2B or RGRWT2W) at convenient interior location 6. Connect thermostat to control unit using proper wiring 7. For older ARC/ARH systems: Install adapter harness WJ35X35673 between AC unit and control box 8. Verify all electrical connections are secure and properly terminated 9. Test system operation in all modes (cooling, heating if heat pump, fan speeds) 10. Configure thermostat settings and verify diagnostic functions Important Compatibility Notes: • This control unit is for SINGLE ZONE systems only (one thermostat, one AC unit) • For dual-zone systems, different control units are required • Thermostat is NOT included and must be purchased separately • Ceiling assembly is NOT included and must be purchased separately • Not compatible with non-GE RVAC systems
