Toshiba 02 fault code Toshiba air conditioning
What it means OPERATION lamp flashing 5 Hz: protective circuit, OUTDOOR P.C. board
Stage-one block code. Toshiba: "Protective circuit operation for outdoor P.C. board". ⚠️ The lamp pattern is the SAME as 00 — OPERATION alone at 5 Hz — so the lamps cannot separate indoor from outdoor. Only the remote check code can.
UK models this code applies to From the Toshiba service literature we hold (Toshiba service manual SVM-19001-3 (Seiya) / SVM-18009 (Shorai P) §11-3, Table 11-3-1 (flashing-LED block codes)) — not a scraped list.

Now the harder half: proving what caused it 02 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.
