Broan range hood troubleshooting

Broan range hood troubleshooting. A Broan range hood/stove vent hood above your stove needs regular maintenance and cleaning to ensure that it is properly performing.

If you notice the range hood not working properly, the most common reasons why your range hood may be faulting are due to grease build-up within the venting system.

Or if the exhaust has been compromised and therefore blocked by another obstruction within your kitchens such as a wall or cabinet.

The problems listed below can arise if your range hood is not effectively working and these tips & methods will help you get your Broan Range Hood up and running in no time.

Occasionally, regardless of how well you take care of your Broan range hood, there will come a time when the range hood itself is in need of some care and attention.

Here are some common problems that may arise if the range hood’s industrial filters are not properly placed to stand up to even the heaviest use:

The Broan range hood motor hums

The blower motor usually hums but doesn’t turn when the blades don’t rotate or when the fan blades swing during high power operation. The motor is out of balance in this case and requires replacement.

Some motors have oil ports in shaft bearings; if the motor has oil ports, they should be filled with approved light machine oil and balanced before installing back on the device.

Tightening up the bolts thoroughly may restore enough bearing protection to let the fan run until a new one can be purchased and installed.

The range vent hood keypad is not working

If you want to check if the touchpad is defective, try pressing some of the keypad buttons. Those that work and those that don’t may indicate a problem with the device.

This could be a problem with the control board. First check to see if all of your more common parts are working properly and if those items are operational, then consider replacing the control board under warranty before purchasing a new one.

Loud or noisy range vent hood motor

Remove the motor from its mount, and check it to judge whether it’s running correctly.

If the motor definitely isn’t working properly, use a multimeter to analyze whether or not there’s continuity in the wiring between the motor terminals.

If there is no continuity, this means that the most likely problem is that you need to replace or repair your motors as they’ve been worn out.

Testing for continuity could help save you some time by eliminating troubleshooting efforts.

Once you’ve managed to determine that the problem lies with your motors, don’t attempt to fix or restore them via some DIY effort because if they have been damaged beyond repair, it might simply be better to purchase a new set of motors altogether.

The range vent hood lights do not work

One or more of the halogen light bulbs may be burnt out. Check your bulb for continuity to ensure that no connections have been broken due to a burnt circuit board inside the housing.

Be aware of any burned residues on the bulb by using a pair of tongs to grip it (make sure they are clean too) and give it some gentle tugs so as to check if it is still intact.

If you find any broken connections, then check your florescent light housing and use a multimeter set on continuity mode to test for power across your three wires (two parallel and one longer lead).

The Broan range hood fan does not work

Test the fuse for continuity with a multimeter to determine if it has blown. A blown thermal fuse needs to be replaced.

If you plug a vent hood into an existing outlet in your home or business, plug something else into that same outlet as a control to see if that troubleshooting move helps.

If there is not another object connected to your home’s outlet at this time and the vent hood still isn’t working properly.

Check your house circuit breaker or fuses altogether rather than taking apart a more commonly defective part such as the main control board of the unit.

Downdraft vent won’t stay up

To troubleshoot your ventilation hood or range in your kitchen and attempt to return power to it, do the following steps:

The first test is whether the rocker switch is in fact defective by using a multimeter to check if there is continuity at every setting.

If a multimeter shows that there is continuity through each of its settings then you know that the rocker switch is defective and needs to be replaced.

If the multimeter isn’t detecting any valid continuity for the selector switch then it simply means

that the problem lies somewhere else within its circuit making it necessary for you to consult your brand’s wiring diagram so as to determine what might have gone wrong within its circuit components ( resistors, capacitors, etc.)

Downdraft vent will not go down

To ensure the rocker switch is not faulty, utilize a multimeter to test for electrical continuity across the two prongs at either end of the switch.

If there is no connection between prong 1 and prong 2 or if there is any visible damage on either outer surface of the switch then replace it with a new one.
