First check
1 Let it cool, then read the drive LED
On Bosch BOVA 2.0 overcurrent / overheat is often a dirty coil, a failed OD fan, or a locked compressor — not a dead inverter. Clear airflow, confirm the OD fan, and read the drive LED before you order a control. Blade free? Ice/wind lock?
Expect: OD fan running. Coil clean. Drive LED decoded from THIS outdoor’s card.
The rest of the walkthrough is Diagnose.
On the plates
- Blade free? Ice/wind lock?
- Motor vs board: resistance and drive voltage per the 5-wire or 3-wire diagram on THIS BOVA.
- A dead outdoor fan becomes P1/P0 next.
