What to do if my Respironics Humidifier shows a blinking blue LED?
- TTristan MillerAug 21, 2025
A blinking blue LED on your Respironics Humidifier indicates a communication issue between the therapy device and the humidifier, improper seating of the therapy device, or a heating problem. Here's what you can do: 1. Check the power connections and ensure both the humidifier and therapy device are properly plugged in. 2. Remove and reconnect the therapy device to the humidifier base, ensuring proper alignment and secure connection of the air inlet and outlet ports, and that the therapy device air outlet port is removed. 3. If the issue persists, contact your home care provider or Respironics. Note that you can still use the humidifier temporarily as a passover humidifier even if the water is not heating.
