TROUBLESHOOTING

Problem

Possible Cause

What To Do

Fan and lights do not operate

This hood is equipped with a main 

power disconnect switch. It is 

located  behind the grease filters 

on the right side of the hood on 

the control housing. 

Flip this switch and press Fan/Light buttons again.

A fuse may be blown or a circuit 

breaker tripped. 

Replace fuse or reset circuit breaker.

The blower connector is loose 

or not plugged into its mating 

connector. 

Disconnect power to the unit. Locate blower and cable 

coming from it.  Follow cable until you find the connector. 

Make sure each blower connector is securely plugged, 

one into the other.

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 off and on cycling 

continues, call for service.

Loud or abnormal airflow 

noise

Wrong size duct used in 

installation. 

This hood requires 8” ducting and a maximum duct length 

of 100 equivalent feet to perform optimally. Using smaller 

duct pipe or longer equivalent lengths of duct pipe will 

cause improper venting. Monogram service technicians 

cannot correct this issue if installed improperly.

Fan fails to circulate 

air or moves air slower than 

normal and/or fan is making 

loud or abnormal airflow noise

Make sure nothing is blocking the vent, including bird & 

other nests or fallen pieces of dry wall.

Damper blade in hood exhaust 

outlet or at wall/roof cap may be 

stuck. 

Make sure all damper blades open freely.

Make sure installer has used the correct size duct, not 

exceeded the recommend equivalent length of ducting and 

all duct pieces are properly connected and sealed.

Non-rigid duct work is prohibited 

in these applications.

If used, look for kinks or other restrictions.

Metal grease filters and/or 

charcoal filters (if present) may be 

dirty. 

Clean the metal grease filter and replace charcoal filter (if 

present). See Care and Cleaning instructions.

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.

The hood controls are not 

operating correctly

Control logic confused. 

Disconnect power to the hood by resetting the circuit 

breaker. Wait 30 seconds to allow controls to reset.

Early-life bulb failure

Replacing bulbs with bare hands. 

Replace bulbs while wearing gloves to keep skin oils off 

bulbs.

Bulb wattage is too high. 

Replace with correct wattage.
