The most common fault causing this is a low battery. If not Take the board in for testing. We do it no charge at the counter. By the way two things can shut you down as you discribe other than the board. The sail switch could be bad, but that is very rare or the high limit switch could be bad this is more common. The sail switch not closing is more comonly a lack of air flow caused by intake or exhaust restriction or slow running motor. Good Luck |
