Amana 8 Flashes

What does Amana 8 Flashes mean?

Eight red flashes indicate an igniter relay fault, and the furnace is not operating. The control cannot drive the igniter correctly. The fault traces to improperly connected igniter wiring, a bad igniter, poor unit or burner grounding, or a faulty integrated control module that cannot energize the igniter relay as expected.

Symptoms

• Furnace not operating
• Integrated control module diagnostic LED flashes eight red flashes
• Igniter does not energize properly
• No ignition sequence

Common causes

• Igniter relay fault on the integrated control module
• Improperly connected igniter wiring
• Bad igniter
• Poor unit ground or poor burner ground
• Faulty integrated control module

Diagnostic steps

1. 01

   Check the igniter wiring

   Check and correct the wiring from the integrated control module to the igniter.

2. 02

   Replace the igniter

   Replace a bad igniter with the proper replacement part. The igniter is fragile, so handle it with care.

3. 03

   Correct the ground

   Check and correct the unit ground wire to resolve poor unit or burner grounding.

4. 04

   Replace the control module

   Replace the integrated control module if it is bad after the wiring, igniter, and ground have been verified.

5. 05

   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 igniter relay fault often requires distinguishing between a bad igniter, a grounding problem, and a failed control board, which calls for electrical testing. If correcting the wiring and ground does not clear the eight-flash code, have a qualified servicer confirm the diagnosis before replacing the control module. Turn power off prior to repair and follow electrostatic discharge precautions when handling the board.
