Symptom
Bosch range hood not working
A fan that will not run, one stuck on a single speed, lights that have gone, or a hood that sounds healthy and moves nothing. Four different problems, and you can tell them apart from the kitchen floor.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
Filters
A grease filter that has been washed a hundred times, or a charcoal filter on a recirculating hood that nobody knew was a consumable. The most common answer to "no suction".
Maintenance & descaling from $145 -
The duct and the outside cap
A wall or roof cap with a corroded damper that no longer opens. Near the water this is common, and the hood sounds perfectly healthy while it happens.

The speed control or switches
A hood stuck on one speed, or one that only works on high. That is the control rather than the motor.

The motor or its capacitor
A hood that hums without turning is usually the capacitor; one that is silent is usually the motor or its supply.

The connected pairing with the cooktop
If the hood used to come on by itself and stopped, that is a link between two appliances that has dropped — a setting, not a repair.

-
01
Pull the filters out and look at the light
Through them. If you cannot see light through the mesh, that is your suction gone.
-
02
Hold a tissue to the hood on full
It should hold there. If it drops immediately, nothing is being pulled and the question is filters or duct.
-
03
Look at the outside cap
From the balcony or the garden if you can reach it. A damper corroded shut is invisible from inside the kitchen.
-
04
Check the breaker for the lights
Lights and fan sometimes sit on different circuits, and a hood with one working and not the other is telling you something.

What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Bosch range hood not working
The fastest diagnosis is the code
There are no error codes on this equipment and none are needed. What the hood is doing — nothing, one speed, no lights, or no suction — is the whole diagnosis.
Four problems you can tell apart yourself
- Nothing at all: power, or the control
- Stuck on one speed: the speed control
- Runs but pulls nothing: filters, then duct, then the outside cap
- Lights only: lamps or the light circuit, often separate from the fan
The salt-air version
Near the water, the outside end of the duct ages first. A cap with a corroded damper stops opening, and the symptom is not a noise — it is a kitchen that stays smoky behind a hood that sounds completely healthy. Worth checking from outside before anyone opens the hood itself.

Before you book
Questions about bosch range hood not working
It sounds fine but the kitchen still fills with smoke.
Filters first, then the duct. A long run with two elbows moves a fraction of the rated airflow even when everything works, and a corroded cap moves nothing at all while the fan roars.
Mine does not vent outside.
Then it recirculates, which in a condo is most of them. The charcoal filter is the entire system, it cannot be washed, and once saturated the hood is just moving air around the room.
It used to switch on with the cooktop.
The pairing between them has dropped, usually after a router change or an update. It is a setting and worth trying to re-establish before booking anything.
