Causes of the blinking purge light on Honeywell

When the Honeywell purge light blinks, it often means the air sensor isn’t connected or is having issues. This sensor is like the system’s detective for temperature, and if it’s not working right, the light gets all blinky.

Don’t stress though; your Honeywell system is still running, but it won’t be able to set extreme temperature limits. Checking and fixing the air sensor usually does the trick to stop that blinky light.

If the purge light on your Honeywell device is blinking, it might be because of a few reasons. First, check if there’s a problem with the power supply. Make sure it’s plugged in properly. If that’s not the issue, see if there’s a blockage in the air intake or exhaust vents. Clear any obstructions you find. Check if the fuel supply is sufficient. Sometimes, a low fuel level can trigger the blinking light.

Lastly, inspect the ignition system to ensure it’s working correctly. If you’ve checked all these things and the light still blinks, it’s a good idea to contact Honeywell support for further assistance.

Discharge sensor not attached

Discharge sensor

Make sure the discharge air temperature sensor is plugged into the DATS terminals. Also, confirm that the discharge air temperature sensor (DATS) is correctly connected to the panel, following the diagram provided, especially if you’re using a Totalzone controller.

The discharge sensor is not connected. This means it’s not properly attached to where it should be. To make things work right, we need to fix this and make sure the sensor is connected correctly. Check the connections and make sure everything is plugged in the way it should be. Once it’s attached properly, things should start working as they’re supposed to.

Failed Discharge Air sensor

If the sensor looks like it’s connected well, but the purge light keeps blinking, your discharge air sensor might be broken. If that’s the case, you should consider getting a new one to solve the issue.

The Discharge Air Sensor didn’t work properly. It’s a part that helps the system know how warm or cool the air is, but it couldn’t do its job right. This caused a problem because the system couldn’t understand the air temperature like it should. So, fixing or replacing the sensor is needed to make things work well again.

More issue that can cause the purge light to flash

If you notice the purge light, it could be because you have two areas in your place asking for different settings like one wanting warmth and the other needing cool air.

Sometimes, the system clears out between these requests. Keep in mind, certain setups might also clear out for a bit after you ask for heating or cooling.

To understand exactly how your zoning control works, take a look at the manual. It’ll tell you the step-by-step process for your specific setup.

Sometimes, the purge light blinks because of other problems. It’s like a signal that something might not be quite right. Maybe there’s a small hiccup in the system or a glitch that needs fixing. So, if you see the purge light flashing, it could be because of some other issues that need a little attention. Just like a car dashboard warning, it’s a way of saying, “Hey, check me out; something needs a bit of fixing here.

Troubleshooting steps for the blinking page light on Honeywell

Make sure that every area is asking for air conditioning.

Give this a shot:

  • Press the purge override and check the airflow in all areas.
  • If one zone is still not working, confirm the control board is sending power to that damper.
  • Use a meter if available, but if all lights are on, it’s likely the damper is stuck. You can free it temporarily, but the issue may recur.
  • Options:
  • Replace the damper motor.
  • Replace the damper.
  • If it’s a “spring open” damper, manually open it and disconnect the wire for that zone.

Make sure it stays open all the time because it can’t ‘power close.’ If the area is supposed to be open continuously, check that all the wires are connected correctly and your thermostats are working well for heating and cooling. If everything else seems fine, there might be an issue with the panel board.

Final thoughts

If you see the blinking purge light on your Honeywell mini zone controller, it means there might be a problem with the discharge air sensor or other parts of the system.

Make sure the discharge air sensor is firmly connected, and think about getting a new one if needed. Also, look for any loose connections and parts that might not be working, like the zone controller board.
