One Flash – No Power Exhauster
The below troubleshooting information is related to situations where the power
exhauster does not cycle on:
• When there is a ONE ash troubleshooting code, the unit is indicating
that the pressure switch is not closing within 30 seconds of the power
exhauster being energized.
• To determine the cause of the issue, check to see if the power exhauster is
cycling on. If the power exhauster is NOT cycling on, then continue to the
possible causes listed below. If, however, the power exhauster IS cycling on,
go to page 13.
Possible Causes:
• Defective exhauster motor
– This occurs when the exhauster motor is receiving 115 volts from IND
and NEUTRAL terminals on the board, but the exhauster will not run. To
solve this issue, the exhauster needs to be replaced. Verify and replace if
necessary.
• Defective control board
– Not sending 115 volts from IND and NEUTRAL terminals to exhauster. To
solve this issue, replace board.
– Before replacing the board, review page 23 on control board
troubleshooting steps.
