HOOTING
Problem
There is no power going to the
fan.
There is power to the fan, but it is
not operating.
There is power to the fan, but it
just hums and does not turn.
The fan is turning and seems to
work fine, but there is not enough
draft.
The fan vibrates.
What to do
Check the circuit breaker.
Turn fan speed control ON.
Turn disconnect switch ON.
Check and correct problems with
connections.
Check and correct problems with
connections. Pay special attention
to the wiring of the junction box.
Increase the setting with the
plastic screw on the front plate.
Check the voltage before the fan
speed control and after. If there is
power before, but not after the fan
speed control, the fan speed
control is bad and must be
replaced.
Check the capacitor and replace if
necessary.
Clean the fan, especially around
the shaft.
This rarely happens, but if it
happens, it is usually to the model
RS9, which have less power than
the bigger models.
Leave the fan ON, even though it
is only turning very slowly. After 5-
10 minutes it will pick up full
speed. You can leave the fan on
and run it at a low speed, if you
don't want to experience the
situation again during extremely
cold weather.
Replace with a larger fan.
Replace motor.
Straighten out/realign the hinges.
Probable Cause
The circuit breaker may be OFF.
Fan speed control is turned OFF.
Disconnect switch (if installed) is
turned OFF.
Bad electrial connections.
Bad electrical connections.
The fan speed controls low
voltage setting is set too low.
The fan speed control may be
bad.
The motor run capacitor may be
bad.
If the fan has not been used for a
long period of time, creosote may
have made the shaft stick.
If sub-zero conditions are present,
the grease in the bearings may
have thickened.
The fan may be under-sized.
The motor shaft may be bent.
The hinges may be bent.
