Troubleshooting

Symptom: The fan does not run.
• Check for an open fuse or circuit breaker in the building's
service panel.
• Check that the two (2) plug-in connections for the Motor
and the Control are seated firmly in place.
• Check that the Blower Wheel spins freely.
Symptom: The fan runs erratically.
• Check that the Blower Wheel is firmly attached to the
Motor shaft and both spin freely.
Symptom: The fan seems noisy.
• Check that the back draft damper in the fan's Duct
Connector pivots freely. Screws used to attach the duct to
the Duct Connector may be preventing the damper from
opening.
• Check that the back draft damper in the wall or roof cap
pivots freely. These dampers are sometimes mistakenly
painted shut or obstructed by bird and insect debris..
