E2

Lockout

Low-stage PS open

Inducer on low, low-fire switch never closes. Classic 96% trap / PVC.

3 plates — walk the one on the cabinet

First check

1 Prove inducer and the live code

Do not pull power — that clears the Daikin DM80VC active code. Write E2. Is the inducer spinning on this call? Silent inducer is not a pressure switch. This is Category I metal vent. There is no 96% collector or PVC trap to prime.

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.
