Before diving into the update saga, let’s quickly recap. The SMEG 317AR3 is a 50’s Style fridge freezer with a 317-liter net capacity, featuring:
While the mechanical reliability of SMEG fridges is legendary, the smart electronics introduced in the 317AR3 series have been a double-edged sword. The recent firmware update was supposed to enhance app connectivity and optimize compressor cycling. Instead, it broke several core functions.
The compressor would start and stop erratically every 3-5 minutes, causing unusual buzzing sounds and raising energy consumption. smeg 317ar3 update fixed
The original firmware polled the evaporator and ambient thermistors every 90 seconds. Under specific humidity conditions, a timing overflow caused the main controller to skip readings for up to 12 minutes. This led to the compressor running too long (freezing the evaporator coil) or shutting off prematurely (spoilage risk).
Buttons on the internal LED display became laggy or stopped working entirely. Some users reported the display showing “Er” or “F5” error codes. Before diving into the update saga, let’s quickly recap
