61 Fan fault
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. Check intake and exhaust for blockages and debris.
3. If the fan does not rotate during the ignition sequence, check for AC8V~26.5V power at the fan connection.
IfAC8V~26.5V power is present at the control, replace the fan. If the blower does not have AC8V~26.5V power,
check power at the control. If AC8V~26.5V power is not present at the control, replace the control.
4. If the problem persists,
