First check
1 Confirm this is not a fault
On the Daikin DM97MC this readout (% / run status) 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 treat a low percent as a lockout. The stat asked for that rate.
- If it never leaves minimum, look at the call, the valve offset, and inducer prove — not a missing W2.
