A loose connection in the thermostat circuit - as well as a thermostat that's chattering can easily create problems. It causes the compressor to start/stop/start, and that will cause it to lock out on a high starting current fault. The module will lock out for a time, and the diagnostic LED will flash 3X....3X....3X... during that period. It will self-reset and try again. It will also tell you if there's a problem with voltage, among other things. The LED will tell the tale, and is the 1st step in DX any problem with the Danfos/SECOP module, as noted in post #7. Without it, you're guessing. You can post symptoms to the forum, then you get six guys all guessing.



Here's a good explanation of the LED use by Coastal Climate Control. They will sell you the LED, you can make one up with a loose LED and resistor if you've got the materials on hand. Start with that and find the problem.
