Error 3 & 4: Extended Thermal TripUpdated 2 months ago

These errors mean the BedJet detected a sustained temperature above the target setpoint. Causes can include restricted airflow or a failure of the temperature sensor.

Step-by-step fix

1. Check for airflow blockages
   

• Remove and clean the BedJet air filter.

• Inspect the air hose end-to-end and clear any obstructions (e.g., socks, bedding).

• Make sure sheets/comforters aren’t bunching at the nozzle.

• Verify nothing is blocking the BedJet’s air intake on the base unit.
  
  

2. Reset the thermal sensor

• Unplug the BedJet from the wall for 1 full minute.

• Plug it back in and power on.

• Run in COOL mode for 10 minutes (this helps the sensor normalize).

• Try your usual HEAT/COOL settings again.
