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.
