Reading the furnace display

A furnace reports faults on a small status LED on the control board, seen through the sight glass in the blower door, or on a two-digit display. Watch a full cycle of the pattern and count the flashes, including the pause between groups, before you decide what you saw. The code chart is on the label inside the blower door. Amana models often flash lights instead of printing text, so count the flashes.

Amana is a Whirlpool Corporation brand sold mostly through builder and value channels. Its entry-level washers, dryers and ranges use the simpler Whirlpool-family control boards, so the codes are short and often shown as flashing lights. The codes apply to model numbers such as ADB1200AWS, ADB2200AWS and NDE2330AYW; check the label on your unit to confirm yours.

What causes E2

How to fix it

If you smell gas, leave the building and call your gas utility from outside; do not touch switches or the furnace. Switch the furnace power off before you open the blower door or touch the igniter or flame sensor, and call a licensed HVAC technician if you are not sure.

The code meaning comes from the manufacturer document listed under Sources. The causes and steps below are general troubleshooting guidance, not the manufacturer's service procedure.

  1. Check outdoors that the vent and intake pipes are not blocked by snow, ice, leaves or a nest.
  2. Switch the furnace power off and inspect the pressure switch hose for kinks, cracks or water.
  3. Do not bypass the pressure switch.
  4. A technician should check the flue piping, the induced draft blower, the switch and the wiring.
  5. Restore power and run a heating cycle. If the code returns, call a licensed HVAC technician and give them the code, the board label and the furnace model number.

Questions

What does E2 mean on a Amana furnace?

E2 on a Amana single-stage furnace means the pressure switch circuit is not closing when the inducer runs. The inducer may run continuously with no furnace operation.

Can I reset the furnace myself?

The control can be reset by switching power off at the furnace switch or breaker for about 30 seconds, which clears some lockouts. If the same code returns, the fault is still present and the control will shut the furnace down again. Never bypass a safety switch to keep it running.

When should I call a technician?

Call a licensed HVAC technician for anything involving gas, the pressure switch, the limit or rollout switches, the igniter, the flame sensor or a control board replacement, or if the code keeps coming back after the simple checks.
