Estimated repair cost: $250 — $600 (parts + labor)
Warning: Your Amana furnace has detected a problem with the blower motor and has likely shut down to prevent further damage. You will have no heat until this is resolved.

How to Fix Amana Code 9R

  1. Step 1: Check the furnace filter. A severely clogged filter restricts airflow and can overwork the blower motor. Replace it with a clean filter.
  2. Step 2: Ensure all vents in your home are open and unobstructed. Closed vents increase static pressure and strain the blower motor.
  3. Step 3: Reset the furnace by turning off the power at the breaker for a few minutes, then turning it back on. This may clear a temporary fault. If the code reappears, call a qualified HVAC technician for diagnosis and repair.

How to Reset Amana Code 9R

  1. Turn off the furnace power switch, usually located on or near the unit.
  2. Turn off the circuit breaker for the furnace. Wait 30 seconds.
  3. Restore power at the breaker and flip the furnace switch back on.
  4. Set the thermostat to call for heat. If the error code returns after 2-3 ignition attempts, the fault requires repair.

Resetting clears the code from the display but does not fix the underlying fault. If the code returns after reset, proceed to the diagnostic steps above.

What Does Amana Error Code 9R Mean?

The 9R error code on your Amana furnace indicates a fault within the blower motor system. The blower motor is responsible for circulating heated air throughout your home. This error means the control board isn't receiving the expected feedback from the blower motor, or that the motor is drawing too much or too little current. This can happen due to a variety of electrical or mechanical issues. Because the furnace relies on the blower to safely distribute heat, it's designed to shut down when this fault is detected. This prevents overheating and potential damage to other components.

Common Causes

  • Failed or failing blower motor
  • Loose or damaged wiring connections to the blower motor or control board
  • Faulty blower motor capacitor (if applicable)
  • Obstructed blower wheel (debris buildup)
  • Defective control board

Diagnostic Steps

If... Check Expected
Blower motor is not running Measure voltage at the blower motor terminals with the furnace calling for heat Correct voltage (typically 120VAC or 240VAC depending on the motor)
Correct voltage is present at the motor Measure the blower motor capacitor with a multimeter Capacitance within +/- 10% of the rating on the capacitor
Motor runs but throws code Measure amp draw of the blower motor while running Amp draw within the range specified on the motor nameplate
Wiring appears damaged Check continuity of all wires between the control board and blower motor Less than 1 ohm
