Verify Proper Operation & Lock in Settings
Reconnect power to the air handler. A flashing Yellow status LED and solid Red (COM) LED indicate proper communication
A If the Yellow LED is off, verify power to the QwikSwap V3
board. If the RED LED is off or flashing, there is a communication error.
b Lock in the Configuration. With power still being supplied to the
QwikSwap V3 board, set all configuration switches to OFF.
C Set the Fan to On. Following a short delay, the Green (HIGH) LED should initially light and then settle on one of the (HIGH), (MED) or (LOW) LEDs.
d Set the Fan to Off. Following a short delay, all the Green LEDs should turn off.
Install the Replacement PSC Motor & Capacitor (same rotation and
voltage)
a Install the replacement PSC motor, mount the QwikSwap V3 board and run
capacitor.
b Connect the PSC motor common wire to the MOTOR COM terminal on the
QwikSwap V3 board.
c Connect the three PSC motor speed taps to the corresponding terminals
on the QwikSwap V3 board
