Troubleshooting Tips
Professional Range Hood
Problem
Possible Cause
What To Do
Fan and lights do not
operate when
the switches are
turned on
The hood was never
electrically connected by the
installer/electrician/builder.
Call the electrician/installer/builder to complete
the installation. This is not covered by
warranty.
A fuse may be blown or a
circuit breaker tripped.
Replace the fuse or reset the circuit breaker.
The blower does not
work but the lights do
The blower motor wire harness
was not connected or was
not connected properly by the
installer/electrician/builder to
its mating connector located
inside the hood on the top
surface, to the left of the
blower assembly.
1. Switch power off at service panel and lock
the service disconnecting means to prevent
power from being switched on accidentally.
When the service disconnecting means
cannot be locked, securely fasten a
prominent warning device, such as a tag, to
the service panel.
2. Remove the filters and locate the blower
wire harness connector. Is it plugged into its
mating connector?
3. If no, plug the blower motor connector into
its mating connector on the top of the hood.
Switch the power back on. Check to see if
the fan now works.
4. If no, check the circuit breaker/fuse. If it is
blown/tripped, replace/reset it. Does the
blower work now? If no, call Monogram for
service.
The blower fails
to exhaust the
smoke/steam/odors
adequately
Many factors could be the root
cause for reduced air-flow.
Installation could be the
problem.
Your hood was designed to meet specific
ducting requirements. If your duct length
exceeds the manufacturer’s requirements,
hood performance will suffer. Air-flow will also
be reduced if the house duct work is too small
or there are too many elbows in the system.
Contact your installer or builder.
Obstruction in duct work could
be the problem.
Make sure nothing is blocking the vent (bird
nests or kinks in the duct work).
Damper blade may not be
opening.
Make sure the tape is removed from the
damper blades and that it swings open freely.
Damper blade on Wall or Roof
Cap may not be opening.
Contact your builder so they can make sure the
damper swings open freely.
Dirty filters/baffles
Make sure filters (and all hood surfaces) are
kept clean of grease and dirt.
Check to be sure the filter is
clean.
If replacing the filter does not correct the
problem, call for service.
Sufficient makeup
(replacement) air is required
for exhausting appliances to
operate to rating.
Check with local building codes, which may
require or strongly advise the use of makeup
air. Visit
Monogram.com
for available
makeup air solutions.
