The sunlight shouldn't affect it. I can't think of any way that it would. "I have solid green and orange LEDs, " But that doesn't mean that they are aligned correctly and the slightest vibration could throw them off. They can be close enough to make the LEDS light up while the door isn't moving. Watch the LEDS while it is closing and see if they blink. Use a string or straight edge if you have one that is long enough, or you can also use a laser level. Using a string is easiest to describe, so I will use that example. I hope you can figure out my instructions! It's easier with two people but if you are doing it alone. Tie the string below one sensor and pull it over the top of it, then over the top of the other sensor. The string should lay flat across both. Adjust if needed. Then tie off to the side of one and pull across the other and adjust that axis also. Repeat step one in case the adjustment moved the other axis. I hope this helps.

We have a brand new KA (we just finished out house in Dec). It closes fine. I just went out and rechecked and if you bring the doors (either one) to the 90 degree position; i.e at right angles to its normal closed position and simply let your hand off of it WITHOUT pushing it closed, it swings closed by itself all the way. Our KA French door has cabinet panels on it. I did find that if I close either door to within 4" of fully closed and let go of them there the left door (with the extra pivoting flange) does not fully close. No problem at all. Jim

Good suggestions on the updates as well as the anti virus. I'd also recommend doing a registry scan/clean. That is how alot of the little bot programs hide themselves..can scan for free too like the antivirus Andie Here is a link that might be useful: registryeasy.com
