How it shows: 7-segment display on a *CVC96 or *MVC96 two-stage furnace covered by IOG-2015L, including Amana AMVC96 and ACVC96: EE6. The chart lists this during otherwise normal furnace operation

Amana EE6 is a low flame-sense signal while the furnace can still be operating normally. The chart says the flame sensor may be coated or oxidized, or sitting wrong in the flame, or the flame is lazy because of gas pressure or combustion air. Cleaning and the gas-pressure comparison to the rating plate are technician steps. EE0 is the lockout after the signal fails often enough.

Likely causes

Flame sensor coated or oxidized
Flame sensor positioned incorrectly in the burner
Lazy burner flame from improper gas pressure or combustion air

Safe checks for EE6

The furnace may still be heating. Write down EE6
Technicianclean the flame sensor if it is coated or oxidized, check its alignment, check the inlet air piping, and compare gas pressure with the rating plate

Safety firstIf you smell gas, do not touch any electrical switch or use a phone in the building; leave immediately and call your gas supplier from outside. Turn off electrical power at the furnace switch or breaker before opening any panel, and never bypass or jumper a limit, rollout or pressure switch. Gas valve, burner, venting, wiring and control-board work should be done by a licensed HVAC technician.

Capacitors can hold a charge after the power is off. Safety terms.
