Amana Furnace Error Code 5 Flashes

Five flashes on an Amana furnace indicates that the rollout limit control is open, which means the furnace detected flame rollout during operation. This safety feature shuts the system down to prevent fire hazard or damage to the heat exchanger. This code applies specifically to units using 50A50, 50A55, HSI 1-1A, or HSI-2 control boards. The furnace will not restart until the underlying cause is found and corrected.

Yes, flame rollout is a genuine safety hazard. It means combustion flames were present outside their intended containment area, which can expose nearby components, wiring, or structural materials to high heat. In some cases, rollout is associated with heat exchanger problems that can also allow combustion gases including carbon monoxide to enter the living space. The furnace should remain off until a qualified technician has inspected and cleared the system.

Repair costs depend on what caused the rollout event. Clearing a blocked flue or realigning burners may cost between $75 and $200 in labor. Replacing an induced draft blower motor typically runs between $200 and $500 including parts and labor. If the heat exchanger is cracked and needs replacement, costs can range from $500 to over $1,500 depending on the unit and availability of parts. A diagnostic service call is usually needed first to identify the specific cause.

Some of the initial checks, such as inspecting the flue and air inlet pipes for visible blockages, can be performed by a knowledgeable homeowner. However, testing the induced draft blower, checking burner alignment, and evaluating the heat exchanger require technical knowledge and proper tools. Because flame rollout is a serious safety condition, it is strongly recommended to have a qualified technician complete the diagnosis and any repairs before restarting the furnace.

Simply cycling power to the furnace will not reliably clear this error because the rollout limit control is a physical thermal switch that must be manually reset or replaced after it trips. Even if the furnace briefly restarts, it will shut down again if the root cause such as a blocked flue or weak induced draft blower has not been corrected. The rollout limit must be inspected for continuity and replaced if it has been permanently damaged by the heat event.
