Fan Speed Feedback Signal Abnorma
This Error Code will go away when the condition is remedied. If Error happens again:
1. Check the connections to the fan. Ensure all are secure.
2. If the fan does not rotate during the ignition sequence, check for 120V power at the fan connection. If 120V power is present at the control, replace the fan. If the blower does not have 120V power, check power at the control. If 120V power is not present at the control, replace the control.
3. If the problem persists, replace the main control
