Double check the alignment of the sensor and magnet, the house may have settled and the alignment may have changed enough to show the fault / set the alarm off. There should be a notch or series of notches on the transmitter, make sure the magnet is centered on that. Also make sure the gap between the two is as small as you get it and still able to operate the windows (both vertically and horizontally). If all that checks out, you could have a tamper switch (GE uses a spring to hold it down) that is not getting fully depressed. or, you may have a bad transmitter. If it is the spring, you may be able to stretch it out a little to ensure good pressure on the tamper switch.

Make sure the battery is exactly what you need. If it is a lithium battery you need to verify the volts - it won't work unless it is exactly the right one. Replacing the lithium battery with one that looks the same won't work if the voltage is different.
If you are using AA or AAA's make sure all dust is removed from the sensor and the batteries are in place properly.
