E6

Protect

Low flame signal

Flame present, µA below the IFC threshold.

Walk E6 in Diagnose

4 plates — walk the one on the cabinet

First check

1 Measure µA while it is running

Do not clean first and guess. Series-µA the rod on Daikin DM80VC during a call. Falling µA is oxide, ground, or a dying flame. A hard drop is often the pressure switch or limit opening, not the rod. Clean rod, chassis ground, manifold / LP conversion.

Expect: Flame rod: µA per this IFC sticker, not the AR9T96 card.

The rest of the walkthrough is Diagnose.

On the plates

  • Clean rod, chassis ground, manifold / LP conversion.
  • µA per this door card, not the AR9T96 sticker.
  • Rod, ground, manifold at the percent it is running — not a single two-stage high-fire number.

Plates that use E6

Same number, other makers

E6 on Daikin is not the same code on these plates.
