Amana EE4 means flame was sensed when heat was not called. The induced draft blower and the circulator both keep running. The chart lists a short in the flame sense circuit, a lingering burner flame, and a slow-closing gas valve. If you smell gas, leave. This is not EE6, which is a low flame signal while the furnace is otherwise operating normally.
Likely causes
- Short to ground in the flame sense circuit
- Lingering burner flame
- Slow closing gas valve
Safe checks for EE4
- If you smell gas, leave and call the gas supplier from outside
- Techniciancorrect a short at the flame sensor or in the flame sensor wiring, and check for a lingering or lazy flame and gas valve operation
Capacitors can hold a charge after the power is off. Safety terms.
When to call a pro
Call a licensed HVAC technician. EE4 means the control sees flame when heat was not requested.
