Amana central air handler or packaged AC shows F1 on the display; blower may not run correctly.

Safety first: Turn off power at the furnace/air handler disconnect and breaker. Confirm power is off with a non-contact voltage tester.

Steps to address F1 (blower fault):

• Access blower compartment: Remove the blower door panel to expose the blower assembly and control board.
• Check wiring: Inspect the blower motor harness and plug for loose connections or burnt pins. Reseat connectors firmly.
• Test motor: For PSC motors, test capacitor and motor windings with a multimeter. For ECM motors, check for 120/240V supply and low-voltage control signals at the motor module.
• Inspect control board: Look for burnt blower relay contacts or damaged traces. If the relay is not energizing with a call for fan, the board may be defective.
• Replace components: Replace a failed blower motor or capacitor with the correct Amana-rated parts. If the motor is good but not receiving power, replace the control board.

ECM motors are sensitive and expensive; handle carefully and avoid static discharge to the control module.
