On most (but not all) Cozy models, the green LED on the sensor is your indicator of proper functionality. NOTE! These lights are only visible during the start-up - there are no lights during normal operation.
If you see a red light or think your Cozy is not operating properly, run this simple test:
- Unplug The Cozy
- Plug it back in
- A green light should shine from the wall temperature sensor. This will display for 5 seconds. You should also hear the fan turn on.
- In addition, please listen for the quiet sound of the fan turning on briefly to indicate that the unit is powering on.
- If there is no light, no fan sounds, or a constant red light, please "Submit a Request" so we can help diagnose what's going on with your Cozy!
For optimal results, keep your Cozy plugged in at all times and ensure the surrounding area is clutter free. Make sure the temperature sensor is not blocked and that the radiator valve remains open.
