How is the Nestera Automatic Door Opener powered?

The Automatic Door Opener for Nestera recycled plastic chicken coops are powered by 4 x AA batteries (not included).

Why is the low battery warning light flashing when I’ve replaced the batteries?

The warning light works on a voltage basis and therefore won’t give a false reading. Check the batteries you’re using are new and fully charged.

If you need further assistance, please contact us.

Why does the LCD display not stay illuminated?

Don’t worry, this is normal. To preserve battery life, the LCD display is designed to enter ‘sleep mode’ after a period of inactivity. You can ‘wake’ it again by pressing the Menu button.

If you need further assistance, please contact us.

My Automatic Door Opener is set up correctly but it’s not working...

Please ensure all 4 x AA batteries are new and inserted correctly. Next check that the battery cable wire is not being pinched between the lid and the box. Then please check that any connector cables haven’t been accidentally loosened while fitting the unit. If these steps don’t offer a solution, contact us.

Why is my Automatic Door Opener displaying the ‘Door Jam’ message?

This indicates that the motor in the unit is having difficulty lifting the coop door. This could be for one of two reasons; either your door is not sliding easily in its runners, or the cord is tangled.

Make sure the runners that hold the coop’s door in place are free from debris and then open the unit to ensure the cord is wound correctly on its spindle.

Please note, the unit cannot be recalibrated with the lid removed. Simply removing and reinserting the batteries will not clear a ‘Door Jam’ message. If you need further assistance, please contact us.

Why isn’t the light sensor working on my Automatic Door Opener?

The light sensor is designed to activate the coop door over a gradual light change. This ensures the door isn’t opened automatically in a lightning storm or in car headlights, for example. The sensor takes an average light reading every three minutes to account for this.

Please note, if your automatic door opener is positioned near a floodlight or streetlight, this may affect the light sensor.

It is best to position your coop away from ambient lighting. If you need further assistance, please contact us.

How long is the cord on the Nestera Automatic Door Opener?

The cord provided with the unit is 4.9ft long. This includes a small length that needs to remain wound around the spindle inside the unit.

Will the clock on the unit change automatically when the clocks go forwards/back?

No, this needs to be done manually on the settings. Don't worry, it only takes a moment.

How long is the warranty on the Nestera Automatic Door Opener?

Nestera Automatic Door Openers are housed in a weatherproof casing, and are remarkably well made and very reliable.

In the unlikely event that something goes wrong with your unit, it comes with a 3-year warranty for your peace of mind.
