Amana 11 Flashes Error Code
Igniter open — broken igniter, bad wiring, or poor grounding.

What does Amana 11 Flashes mean?
Eleven red flashes indicate an open igniter, and the furnace is not operating. The control sees no continuity through the igniter circuit. This is caused by a bad igniter, improperly connected igniter wiring, or poor unit or burner grounding that breaks the circuit the control needs to heat the igniter.
Symptoms
- Furnace not operating
- Integrated control module diagnostic LED flashes eleven red flashes
- Igniter does not heat up
- No ignition sequence
Common causes
- Open igniter circuit
- Improperly connected igniter wiring
- Bad igniter
- Poor unit ground or poor burner ground

Diagnostic steps
Check the igniter wiring
Check and correct the wiring from the integrated control module to the igniter.
Replace the igniter
Replace a bad igniter with the proper replacement part. The igniter is fragile, so handle it with care.
Correct the ground
Check and correct the unit ground wire to resolve poor unit or burner grounding.
Replace the control module
Replace the integrated control module if it is bad after the igniter, wiring, and ground are verified.
Power off before servicing
Turn power off prior to repair and read the electrostatic discharge precautions before handling the control module.
When to call a professional
An open igniter is often a simple replacement, but confirming whether the wiring, ground, or control board is also at fault requires electrical testing. If replacing the igniter does not clear the eleven-flash code, have a qualified servicer verify the circuit before swapping the control module. Turn power off prior to repair and follow electrostatic discharge precautions when handling the board.

Other Amana Error Codes
System lockout from too many failed ignition retries — the furnace could not establish or hold flame.
Pressure switch circuit is closed when it should be open — the induced draft blower is not operating.
Pressure switch circuit is not closing while the induced draft blower runs — restricted airflow or a faulty switch.
Primary or auxiliary limit circuit is open — the furnace is overheating from insufficient airflow.
Flame sensed with no call for heat — a short to ground in the flame sense circuit.
Rollout limit open or the integrated control module fuse is blown — possible flame rollout.
Flame sense microamp signal is low — a coated, oxidized, or misaligned flame sensor.
Igniter relay fault — wiring, igniter, grounding, or control module problem.
Twinning fault — twinned furnaces are not wired or relayed together correctly.
Open fuse / no 24V power to the integrated control module — often from a voltage surge.
Inducer relay fault — inducer wiring, blockage, grounding, or control module problem.
Reversed polarity of 115V or 24V power to the furnace or control module.
