StatusStatus, not a fault
idle = standby. CF = continuous fan. 1AC / 2AC = cooling stage. Htr = electric heat staged. These are run states.

First check
1 Confirm this is not a fault
On the Amana AVPTC this readout (idle / CF / 1AC / 2AC / Htr) is run status, not a lockout. Write what the display actually shows and whether W/Y/G is present at the IFC.
Expect: Idle / Ht / CF / stage+CFM words change when you apply and remove the call.
If fail: If the word never changes on a real call, the call is not reaching this IFC.
If pass: The board is alive. Diagnose the comfort complaint, not this code.
The rest of the walkthrough is Diagnose.
On the plates
- Do not replace the board because it says CF or Htr.
- Htr during a heat-pump call means the IFC thinks aux is needed — check CoolCloud electric-heat / W config before you condemn a sequencer.
