Replacing supply or exhaust fan motor CW-P15 Pdf
When diagnosing a FC # 7 on a CW-P it is important to first check what software revision that the CWP-15 has installed.
Can be checked from the MagIQtouch controller by selecting SETTINGS – COOLER – ABOUT APPLIANCE.
- Earlier versions of software (pre 420319) FC # 7 indicates a MOTOR ERROR, but did not specify whether it's the Supply or Exhaust fan motor faulty.
- Software versions 42R0319 and higher has an additional FC # 13 to assist in diagnosing which motor is faulty.
FC # 7 : Indicates a fault with the Supply Fan motor or motor circuit
- Does the supply fan operate from the service screen for more than 60 seconds?
- Does the contactor close when the supply is requested to run?
- Check that 240vac is present on both side of the filter boards
If all of the above are true, then replace the supply fan.
FC # 13 : Indicates a fault with the Exhaust Fan motor or motor circuit
