Toshiba RELEASE fault code
Toshiba air conditioning
What the Toshiba RELEASE fault code means, from the manufacturer's own service literature, and the UK models it applies to.
What it means
Table 11-3-1 item F, "Release status display". These flash patterns mean the unit is LIMITING ITSELF to stay inside its envelope — they are not faults and there is no check code behind them. Reading one as a fault sends an engineer chasing a machine that is working correctly.

Now the harder half: proving what caused it
RELEASE names a symptom, not a root cause. In the app, the same code opens a guided investigation: what to measure first, the expected values for your exact model, and an honest verdict — including “nothing in this machine is broken” when that's what the readings say.
