Problem

Possible Cause

What To Do

Fan automatically turns on and can 

not be turned off

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. 

Fan does not operate when turned 

on

A fuse may be blown or a circuit 

breaker tripped. 

Replace fuse or reset circuit breaker.

The power disconnect switch inside the 

hood may be 

switched off. 

Remove the metal grease filter and the charcoal 

filter (if present) and flip the switch on.

Fan fails to circulate air or moves 

air slower than normal

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.

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.

Fan keeps going 

off and on

The motor is probably overheating and 

turning itself off. This can be harmful to 

the motor. 

Check to 

be sure the filter is clean

. If it continues 

to cycle on and off, call for service.

Light will not stay on high setting 

or “wrong watt bulb” appears in 

the display

Use 12 volt, 20 watt halogen bulbs with a G4 base 

and make sure they are inserted securely. See the 

Light bulbs section.

The hood controls or display are 

not operating correctly

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.

Sequential presses of the light or 

fan buttons will sometimes change 

the setting from the lowest setting–

to off to the highest setting, or 

from the highest setting–to off–to 

the lowest setting

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.

When pressing the power on/off 

button to turn on the light, the fan 

comes on instead

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.

Save time and money! Review the charts on the following pages first and you may not need to call for service.
