LockoutInducer / pressure band (if shown)
On this modulator these letters are a prove-band / inducer path, not DM96VC low-vs-high discrete switches. Confirm on the DM97MC door card.

First check
1 Prove inducer and the live code
Do not pull power — that clears the Daikin DM97MC active code. Write E1 / E2 / E8 / E9. Is the inducer spinning on this call? Silent inducer is not a pressure switch. Trap, PVC, inducer still matter — 97% still drowns a collector.
Expect: 120 VAC at the inducer on a heat call. Wheel turning.
If fail: 120 VAC missing → IFC / door switch / incoming power. Voltage + dead motor → inducer.
If pass: Inducer running + this code → trap, hose, switch, vent (step 2).
The rest of the walkthrough is Diagnose.
On the plates
- Trap, PVC, inducer still matter — 97% still drowns a collector.
- Do not replace ‘the high-fire PS’ as if this were two-stage.
- If the card in THIS cabinet maps them differently, the sticker wins.
