Two Flashes – Pressure Switch
Closes Before Power Exhauster Energizes
When there is a TWO ash troubleshooting code, the unit is indicating that the
pressure switch has closed before the power exhauster is energized.
Troubleshooting Steps:
1. Pull one of the yellow wires off the pressure switch. If the power
exhauster turns on and the code goes away, replace the switch.
If the code persists, go to step 2.
2. Check the yellow wires to see if they are shorted together. Make sure
the connector for the safety harness is seated correctly on the board.
3. If there are no wiring faults, then there is a defective board
(verify and replace if bad).
