Toshiba 07 fault code

Toshiba air conditioning

What the Toshiba 07 fault code means, from the manufacturer's own service literature, and the UK models it applies to.

What it means

Outdoor return signal stops after start

Block 03. The outdoor unit returned its signal at start-up, then stopped sending after a while. Recorded once detected 4 or 8 times. The indoor unit runs on; the outdoor stops.

Safety: Safe isolation before opening terminal covers — mains present on the interconnect.

Now the harder half: proving what caused it

07 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.
