What to do if Rae QRAE 3 Monitor shows pump failed message?
- A
  Andrew JacksonAug 2, 2025
  If your Rae Monitor displays a 'Pump failed' message or triggers a pump alarm, several issues could be the cause. First, check the inlet probe for any obstructions and remove them, then press the [Y/+] key to reset the alarm. Also, ensure that the gas valve is turned on if directly connected to a gas outlet, and then press the [Y/+] key to reset the pump alarm. If using an external filter, check if it's dirty or sucking in water and replace it if contaminated. Lastly, be cautious of water condensation inside the unit. If none of these steps resolve the issue, the pump or pump circuit may be faulty, requiring a pump replacement.

  If the buzzer, LED lights, and vibration motor on your Rae Monitor are not working, it could be due to a couple of reasons. First, go to “Alarm Settings” in Programming Mode and make sure that the buzzer and/or other alarms are not turned off. If the alarms are enabled, the buzzer might be defective and require calling an authorized service center.

How to fix Rae QRAE 3 Monitor if it cannot turn on power after charging the battery?
- A
  Aaron HobbsAug 21, 2025
  If you cannot turn on the Rae Monitor after charging the battery, it could be due to a defective charging circuit, in which case you should replace the battery or charger. Alternatively, the battery itself might be defective, so try charging the battery again.
