Amana AMVC960803BN Error Code EE6: Low Flame Signal
What Does Code EE6 Mean?
Unlike most codes on this furnace, EE6 does not stop the Amana AMVC960803BN from running. The Integrated Control Module posts it on the dual 7-segment display while the burners stay lit, flagging that the flame-sense microamp signal has fallen below the level it expects for a strong, reliable flame reading. In other words, the furnace is working now but the margin of safety in its flame detection is shrinking.
The flame sensor is a thin metal rod sitting in the burner flame; it passes a tiny current (measured in microamps) whenever a real flame is present. When the rod becomes coated or oxidized, that current weakens. The Amana service data also attributes a low signal to a sensor that is positioned incorrectly in the flame or to a lazy burner flame caused by improper gas pressure or restricted combustion air. Any of these lowers the signal without extinguishing the flame outright.
EE6 is the early-warning end of an escalation chain. As the signal continues to decay, the module will eventually fail to prove a flame during ignition, and after three failed attempts that becomes an EE0 lockout — the same underlying flame-sensing problem, but now with no heat at all. That is why EE6 is worth acting on promptly even though the furnace still runs. On this model the corrective work (cleaning or repositioning the sensor, correcting gas pressure or combustion air) is handled by an HVAC technician rather than the homeowner.
What You'll Notice
- The dual 7-segment display shows EE6 while the furnace keeps producing heat
- The furnace runs, but you may notice occasional short cycles or a flame that looks weak or lazy rather than crisp and blue
- Ignitions may start taking longer or feel less reliable than they used to
- The code may come and go between cycles as the signal hovers near the threshold
- Over days or weeks it may progress toward failed ignitions and an EE0 lockout
Common Causes
How This Is Diagnosed
Because the furnace still runs, a technician can read the live flame-sense signal during a firing cycle and compare it against the expected microamp range for this model, which immediately shows how far the signal has dropped. The most common finding is a coated rod, so the technician cleans the flame-sensor rod and confirms it is seated correctly in the flame path, then re-reads the signal to see whether it recovers.
If cleaning and repositioning do not restore a strong reading, the technician looks past the sensor to combustion quality: gas pressure compared to the rating-plate value and the inlet and flue piping checked for blockage, length, or restriction that could produce a lazy flame. This ordered check separates a simple dirty-sensor case from an underlying gas-pressure or venting issue before EE6 can escalate to EE0.
When to Call a Professional
This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:
- EE6 persists or returns after the furnace has run for a while
- The burner flame looks yellow, orange, or lazy instead of steady and blue
- Ignitions are becoming slow or unreliable, hinting the signal is still dropping
- EE0 lockouts start appearing in addition to EE6
- There is any gas smell during operation
Frequently Asked Questions
My furnace still heats — can I ignore EE6 for now?
It is safe to keep using the furnace short-term because EE6 is a normal-operation warning, but ignoring it usually ends in an EE0 no-heat lockout. Booking service while the furnace still runs is easier than waiting for it to quit on a cold night.
Is EE6 the same problem as EE0?
They are two stages of the same flame-detection issue. EE6 is the early warning that the flame signal is weak while the furnace runs, and EE0 is the lockout that follows once the signal drops far enough that ignition can no longer be proven.
How often does the flame sensor need attention?
It varies with fuel quality, run hours, and local conditions, so there is no fixed interval. Many technicians clean or check the flame sensor as part of an annual furnace tune-up, which typically heads off EE6 before it appears.
