I have been having some problems with my Elite Miracle One, I can't get the gate to close. The Power light and the charge OK lights are on but the System ON light seems to flash or blink when the opener doesn't work. I have turned off the power for a few minutes and after turning it back on the System ON light stops flashing and I can close it. But this doesn't seem to last long and it stops working again when the System ON starts flashing. Any expertise would be greatly appreciated.
