Amana 2 Flashes Error Code
Pressure switch circuit is closed when it should be open — the induced draft blower is not operating.

What does Amana 2 Flashes mean?
Two red flashes indicate the pressure switch circuit is closed at a time the control expects it to be open, while the induced draft blower is not running. The control reads this contradiction as a fault, typically because the pressure switch contacts are stuck closed or there is a short in the pressure switch circuit.
Symptoms
- Furnace fails to operate
- Integrated control module diagnostic LED flashes two red flashes
- Induced draft blower is not running
- Pressure switch circuit reads closed during standby
Common causes
- Induced draft blower pressure switch contacts sticking closed
- Shorts in the pressure switch circuit
- Induced draft blower not operating

Diagnostic steps
Replace the pressure switch
Replace the induced draft blower pressure switch with the proper replacement part if its contacts are stuck closed.
Repair the circuit short
Locate and repair any short in the pressure switch circuit that holds the contacts closed.
Verify induced draft blower operation
Confirm whether the induced draft blower is running, since the fault appears when the blower is off but the switch reads closed.
Power off before servicing
Turn power off prior to repair before handling the pressure switch or its wiring.
When to call a professional
This fault involves diagnosing a stuck pressure switch and tracing shorts in low-voltage circuits while the furnace is de-energized. If you are not comfortable testing pressure switch contacts, locating a circuit short, or sourcing the correct replacement part, have a qualified servicer perform the repair. Always turn power off prior to working on the switch or wiring.

Other Amana Error Codes
System lockout from too many failed ignition retries — the furnace could not establish or hold flame.
Pressure switch circuit is not closing while the induced draft blower runs — restricted airflow or a faulty switch.
Primary or auxiliary limit circuit is open — the furnace is overheating from insufficient airflow.
Flame sensed with no call for heat — a short to ground in the flame sense circuit.
Rollout limit open or the integrated control module fuse is blown — possible flame rollout.
Flame sense microamp signal is low — a coated, oxidized, or misaligned flame sensor.
Igniter relay fault — wiring, igniter, grounding, or control module problem.
Twinning fault — twinned furnaces are not wired or relayed together correctly.
Open fuse / no 24V power to the integrated control module — often from a voltage surge.
Igniter open — broken igniter, bad wiring, or poor grounding.
Inducer relay fault — inducer wiring, blockage, grounding, or control module problem.
Reversed polarity of 115V or 24V power to the furnace or control module.
