Amana

E1

Lockout

Low-stage PS stuck closed

Low-stage pressure switch is made with the inducer off.

Walk E1 in Diagnose

7 plates — walk the one on the cabinet

First check

1 Unplug the switch with the inducer off

On Amana AMVC96 this code is the switch made when the inducer is not running. Unplug that switch only. Unplug the LPS. If the code changes, the switch is welded or the hose is holding residual draft.

Expect: Code changes when the harness is open.

If fail: Wrong switch, or the IFC input is shorted.

If pass: Switch/hose path. Go to step 2.

The rest of the walkthrough is Diagnose.

On the plates

  • Unplug the LPS. If code changes, switch is welded or hose is holding residual draft.
  • Hose routed downhill to the collector? Water in the hose fakes a closed switch.
  • IFC input shorted — only after the switch ohms open.
  • Unplug the only PS. If the code changes, switch is welded or the hose is holding residual draft.
  • There is no second (high-fire) switch to confuse with E8.
  • Unplug the only PS. Code change = welded switch or residual draft in the hose.
  • Hose holding chimney draft with inducer off — wind on a tall stack can fake E1.
  • Unplug the LPS. If the code changes, the switch is welded or the hose is holding residual draft.

Plates that use E1

Same number, other makers

E1 on Amana is not the same code on these plates.
