Amana AMVM970803BN Error Code EE6: Low Flame Sense Signal
What Does Code EE6 Mean?
Code EE6 is a warning code, not a shutdown — the furnace keeps heating, but the flame sensor's micro-amp signal is low. It means the sensor can still detect flame, just weakly, which is an early sign that ignition reliability is degrading.
On this furnace the usual cause is a flame sensor that is coated or oxidized, incorrectly positioned in the burner flame, or seeing a lazy flame from improper gas pressure or restricted combustion air. Because the signal is marginal, it tends to worsen over time.
EE6 is effectively the early-warning stage of EE0 (ignition lockout): if the flame signal keeps dropping, the furnace will eventually fail to confirm flame and lock out. Although flame sensor cleaning is straightforward, this model marks EE6 as a professional item, and the sensor's position and gas pressure should be verified by a technician.
What You'll Notice
- The furnace still heats but the display shows EE6
- Occasional ignition hesitation or the furnace working harder to stay lit
- The warning appears more often over time as the sensor degrades
- The furnace may occasionally lock out with EE0 if ignored
Common Causes
How This Is Diagnosed
A technician inspects the flame sensor for coating or oxidation and cleans it, then confirms it is correctly positioned in the burner flame. They also check the inlet air piping for blockage and compare gas pressure to the rating plate, since a lazy flame reduces the sense signal.
This is described here for information only. Even though EE6 is a low-severity warning, this model routes it to a professional, and gas-pressure verification in particular must be done by a qualified technician.
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 appears repeatedly, indicating the flame signal is degrading
- The furnace begins hesitating during ignition or occasionally locks out with EE0
- You want the flame sensor cleaned and its position and gas pressure verified
Frequently Asked Questions
Is EE6 urgent?
It is a low-severity warning and the furnace still heats, but it tends to worsen. Addressing the weak flame signal early prevents it from progressing to an EE0 lockout in the middle of cold weather.
Is EE6 the same as EE0?
No. EE6 warns that the flame signal is weak while the furnace still runs; EE0 is a full lockout after three failed ignitions. EE6 often precedes EE0 if the sensor is not serviced.
