Why does the airflow from my Friedrich MR12Y1E Air Conditioner become weak or stop?
- M
  Mr. Samuel BlairAug 21, 2025
  Weak or stopped airflow in your Friedrich air conditioner can occur for several reasons: * When heating starts, fan speed is temporarily low to warm internal parts. * During heating, the unit may temporarily stop for 7-15 minutes for automatic defrosting. * The fan may operate at very low speed during dry operation or when monitoring room temperature. * The fan operates at very low speed during SUPER QUIET operation. * In monitor AUTO operation, the fan runs at very low speed.

  Your Friedrich air conditioner might not start immediately after being turned off and on again to prevent fuse issues; the compressor will not operate for about 3 minutes. Also, when the power is disconnected and reconnected, the protection circuit will operate for about 3 minutes.
