A genuine OEM interior ceiling assembly that connects your GRC or GRH series rooftop AC unit to your RV's duct system -- delivering even, room-by-room cooling distribution and a finished interior appearance.
The GE RGRED1A is the factory-spec ducted ceiling assembly designed exclusively for GRC and GRH series RV rooftop air conditioners, including the GRCS and GRHS models in both 13,500 BTU and 15,000 BTU configurations. This is the interior-side component that mates the rooftop unit to your RV's built-in duct network, routing conditioned air through ceiling registers throughout the coach rather than blowing it directly from a single opening.
If your current ceiling assembly is cracked, warped, missing duct ports, or simply worn from years of use, the RGRED1A is the correct direct replacement. Because this is a genuine GE Appliances part, it aligns precisely with the original mounting footprint, duct port positions, and electrical connections -- no modifications required on compatible units.
Engineered to the exact mounting footprint and duct port layout of factory GRC and GRH series installations. No drilling or modification needed on compatible units.
Routes conditioned air into your RV's ceiling duct network for even distribution to multiple registers -- eliminates hot and cold spots common with non-ducted setups.
Provides a flush, finished ceiling appearance that matches the original factory interior, concealing the rooftop unit's interior components behind a trim-ready housing.
Manufactured to GE Appliances specifications. Part number RGRED1A is the correct OEM replacement -- not an aftermarket approximation.
Standard non-ducted ceiling assemblies discharge all cooled air from a single ceiling box directly into the main living space. A ducted assembly like the RGRED1A instead connects to the RV's factory duct plenum, splitting airflow through multiple ceiling registers positioned throughout the coach. The result is more consistent temperature from front to back and better comfort in slide-out rooms and rear bedrooms.
If your GRC or GRH unit was originally installed with a ducted system, replacing a failed ceiling assembly with a non-ducted unit will block your existing duct runs and undermine cooling performance. Always replace like-for-like -- the RGRED1A maintains your ducted system exactly as designed.
Because this is a genuine OEM assembly, you retain the original blower motor routing, filter access point, and duct collar positions without any adapter hardware. Installation typically involves removing the old ceiling box, disconnecting the rooftop unit's interior wiring harness, and reversing the process with the new assembly.
The RGRED1A is confirmed for use with GE Appliances GRC and GRH series RV rooftop air conditioners. This includes:
If you are unsure whether your specific model number requires the RGRED1A, locate the model and serial tag on your existing rooftop unit (typically visible from the roof or on the interior ceiling assembly frame) and confirm it falls within the GRC or GRH family.
The RGRED1A is specifically for ducted GRC/GRH installations. GE RV air conditioners sold with non-ducted ceiling assemblies use a different ceiling box part number. Check your existing ceiling assembly or rooftop unit label to confirm your system is ducted before ordering.
Replacing the ceiling assembly on a GRC or GRH series unit is a straightforward DIY job for anyone comfortable working with RV ceiling panels and low-voltage wiring:
While the ceiling assembly is off, inspect and clean the evaporator coil on the rooftop unit, clear the condensate drain, and replace the return-air filter if equipped. This is the easiest access point for annual AC maintenance and saves you from repeating the removal later in the season.
