Amana 6 Flashes

What does Amana 6 Flashes mean?

Six red flashes mean the rollout limit is open or the integrated control module fuse is blown, and the furnace fails to operate. This can indicate flame rollout from misaligned burners, blocked flue or air inlet piping, or a failed induced draft blower. It can also follow a short in the 24-volt control or safety circuits that blows the fuse.

Symptoms

• Furnace fails to operate with no furnace operation
• Integrated control module diagnostic LED flashes six red flashes
• No heat is produced
• Rollout limit has tripped or the control fuse is blown

Common causes

• Rollout limit open, often from flame rollout
• Misaligned burners
• Blocked flue or air inlet pipe, or a failed induced draft blower
• Integrated control module fuse blown
• Short in the 24-volt AC control or safety circuits
• Loose or improperly connected wiring, or a faulty rollout limit

Diagnostic steps

1. 01

   Check the burners for proper alignment

   Inspect the burners and correct any misalignment that could cause flame rollout.

2. 02

   Inspect the flue and air inlet piping

   Check the flue and air inlet piping for blockage and verify proper length, elbows, and termination, correcting as necessary.

3. 03

   Check the rollout limit

   Check the rollout limit and replace it with the correct replacement part if it is faulty.

4. 04

   Verify the induced draft blower

   Check the induced draft blower for proper performance and replace it with the correct part if it has failed.

5. 05

   Replace the control fuse and tighten wiring

   Replace the integrated control module fuse with a 3A automotive fuse and tighten or correct any loose wiring. Turn power off prior to repair.

When to call a professional

Flame rollout is a serious safety condition that can indicate blocked venting or a compromised heat exchanger. A six-flash code should be diagnosed by a qualified servicer, especially if the rollout limit keeps tripping or the fuse blows again after replacement. Do not reset the furnace repeatedly without finding the cause, and always work with power off prior to repair.
