Possible Cause
A fuse may be blown or a circuit
breaker tripped.
The power disconnect switch inside the
hood may be
switched off.
Sufficient makeup (replacement) air is
required for exhausting appliances to
operate to rating.
The motor is probably overheating and
turning itself off. This can be harmful to
the motor.
What To Do
The Sensor feature will automatically turn the fan
on at the MED setting and the display will show
AUTO MODE ON if cooking temperatures become
too hot. The fan will stay on for a minimum of 3
minutes and will then turn off when temperatures
cool to an appropriate level.
Replace fuse or reset circuit breaker.
Remove the metal grease filter and the charcoal
filter (if present) and flip the switch on.
Check to be sure the metal grease filter and the
charcoal filter (if present) are clean. Clean the
metal grease filter (see the Metal grease filter
section) and, if the hood is recirculated (not vented
to the outside), replace the charcoal filter (see the
Charcoal filter section). If cleaning and replacing
the filters does not correct the problem, call for
service.
Check with local building codes, which may require
or strongly advise the use of makeup air. Visit
Monogram.com for available makeup air solutions.
Check to be sure the filter is clean. If it continues
to cycle on and off, call for service.
Use 12 volt, 20 watt halogen bulbs with a G4 base
and make sure they are inserted securely. See the
Light bulbs section.
Disconnect power to the hood by removing the fuse
or turning the circuit breaker off in the home fuse
box. Wait 30 seconds to allow the hood controls to
reset and then replace the fuse or move the circuit
breaker back on.
It is normal for the light and fan buttons to cycle
around through the settings so that you can easily
set the controls to the desired setting.
For your convenience, it is normal for the lights and
fan to remember their last setting when you press
the Power On/Off button. If you want only the lights
on, press the "FAN +" (or the "FAN –" ) button until
"Off" is in the display. When you power the hood up
next time, only the lights will function.
