Rheem R802VA07542117MSA Error Code A222_F: Model Data Restore Failure

What Does Code A222_F Mean?

Fault code A222_F on the Rheem R802VA indicates that the IFC board attempted to restore model-specific data from non-volatile memory during startup and the restore operation failed. Model data is distinct from configuration data (A221_F) — it contains specifications tied to the exact furnace model, such as firing rates, heat exchanger characteristics, and blower performance curves for this specific R802VA variant. Without valid model data, the IFC cannot correctly control or monitor the furnace.

Like A221_F, model data restore failure can result from a power surge that corrupted internal memory, natural degradation of non-volatile memory cells over time, or a replacement board that was never programmed. The IFC stores this data separately from configuration data, so A221_F and A222_F can occur independently or together.

Resolving A222_F requires a technician with the manufacturer's Bluetooth contractor app to write the correct model data for the R802VA onto the IFC board. If the board's non-volatile memory cannot be successfully programmed — for example, because the memory hardware has failed — the entire board must be replaced with a new unit that is then fully programmed.

Common Causes

When to Call a Professional

Contact a licensed HVAC technician if:

• Any time this code appears — a technician with the manufacturer's Bluetooth contractor app must reprogram the model data or replace the board
• After a control board replacement, the installer must complete the Bluetooth model data programming step before the furnace will operate
• If A221_F and A222_F appear together, both configuration and model data need to be reprogrammed — a technician should complete both tasks in the same service visit
