Rheem R96VA0702317MSA Error Code 99: Remote Faults Reset Performed
What Does Code 99 Mean?
A code 99 on the Rheem R96VA0702317MSA is an informational notification, not an error or fault. It appears in the fault code history to record that a remote fault buffer reset was performed — meaning the stored history of previous fault codes has been cleared. This is a routine maintenance action typically performed by an HVAC technician during a service visit, or automatically by a connected communicating thermostat.
The fault buffer on this furnace stores a history of fault codes that have occurred, allowing technicians to review past problems even after the underlying issues have been resolved. When the buffer is reset, code 99 is logged as a marker indicating the history was intentionally cleared at that point in time.
No action is needed when you see code 99. It does not indicate any problem with the furnace and does not affect operation. Normal furnace operation continues before and after this notification appears.
