Cooptender coop door problems help needed

[Zwillingsmama]

We disconnected the battery and took it out. Than connected it to AC. No lights nothing dead. Same is when we use the battery and attach it with the connectors for the battery. However if I use the wires which should attach to the solar panel and connect the battery with these wires the lights come on and the door looks „Health „

Do you have a voltmeter?

 

[Zwillingsmama]

Yes -

We need to measure the AC voltage on the load side of the switch. Should be 120VAC when the switch is on, and zero when the switch is off. Have you done this yet?

 

[Zwillingsmama]

No haven’t. I am out at the moment but will try tomorrow morning

Interesting that Coop Tender sells individual parts for the DIY. This makes it a bit easier to understand what is inside the door. If you plug it in to AC and it does not light up and the fuse and switch check out ok then I suspect that the power supply has failed. If you can find that part (in the link) you can test to see if the output from it is 15 volts DC.

It looks like the brains (micro controller) are on the faceplate from what I can gather looking at the parts on the web site.

I wish I could find a wiring diagram on it...

Wiring diagram would be nice. There's a pinout of the circuit board connector in the manual. That helps somewhat. The unit works because it runs off the PV panel. So it looks like it's either the switch or the DC power supply (or maybe a bad AC cord or dead wall socket - tripped GFCI?). If there's no 120 VAC on the load side of the switch Zwillingsmama needs to check the AC fuse with an ohmmeter.

The link you gave for the power supply says that it is over-current protected. I'm looking at similar power supplies online and they have a fuse. I don't think that's been checked yet.

Zwillingsmama, before you do anything look to see if there is a fuse on the DC power supply. It's the small circuit board mounted to the wood to the left of the switch (or above the switch in the picture). I think there might be one on the side closest to the AC plugin/switch.

There was no fuse on the power supply I saw, but there is a 2nd fuse where the DC fuse is, both fuses are OK, we tried to measure the AC voltage on the load side of the switch - we couldn't get a read but it is hard to tell if there was none or if we just got the spot(s) wrong. Without taking everything apart it is difficult to reach things. At this point the system is working when connected with the solar panel wires. We have it now on a timer rather than "light" schedule and it opened and closed today without a problem, bypassing the cooptender powersupply and switch/fuse. Would there be any problem if we continue to do so, the system now has no fuse but since we don't really have thunderstorms here I wouldn't know why we need it to begin with - the fuses were only causing problems.
Thanks again for brainstorming with me and trying to solve my problem

Can you take off the front panel and take a picture of the DC power supply? Don't unplug anything; it should just fold down once you get the screws out. The website says the DC power supply is protected, so there should be something. Maybe I can see it. Also I can show you where to measure 120 VAC and 15VDC on the p/s. That way we can tell if it's working. If not it's cheap to replace.
