Which Ruud units show F7

This page applies to Ruud Classic and Classic Plus wall-mount (RIWH / ROWH / UIWH / UOWH), Endeavor Line multi-zone and Floating Air series (2023 and later) units on the Floating Air series (Friedrich-built, Gree platform). Ruud's own documentation lists F7 as "Oil return cycle (cooling)", the same definition used across the Gree platform it is built on. If your unit shows a code with a different shape (for example a four-character code, or a plain number), it is from a different table; use the lookup with your exact code.

Where Ruud shows this code

Floating Air series (Friedrich-built, Gree platform): The code shows on the indoor unit's display in place of the temperature. If the display is off, press the Light button on the remote. Some models also count out the code as indicator blinks. E codes are system protections and faults, F codes are mostly sensor faults, H codes are outdoor and compressor protections, U codes are motor and valve faults, and P codes are power-supply faults.
