(469) 638-3215Range hood fan dead, weak suction, rattling or lights out? ALAS Appliance Repair fixes under-cabinet, wall, island, insert and pro-style vent hoods, including inline blowers, across Denton, from the Downtown Denton Square and the US 380 corridor to Southridge, Robson Ranch and the UNT area.
Business Profile

Many mid-century Denton homes, including those in Crestwood Heights, which dates from the 1950s, and in Southridge, still use a simple under-cabinet hood. Some of these vent outside through a short duct and some only recirculate through a filter, and older units may have a fan motor, switch or light socket that has simply worn out. A hood that hums but barely moves air may have a stuck backdraft damper or a duct clogged with years of grease, so check the outside cap if the hood vents outdoors.
Remodeled kitchens in the historic districts and newer homes across Denton more often have chimney hoods or over-the-range microwaves doing the venting. Start with the filters: wash metal mesh or baffle filters often, and swap out the charcoal pad on a recirculating hood when it is due. Outdoor kitchen hoods on backyard patios face heat, dust and pollen and wear out sooner. Hoods are hardwired, so motor and switch swaps belong with a technician.
Our Plano-based technicians cover Denton from the Downtown Denton Square and the I-35E, I-35W and US 380 corridors to the West Denton historic neighborhoods, Southridge, Robson Ranch, Preserve at Pecan Creek and the rentals around UNT and TWU.
Common vent hood problems
The vent hood problems we see most often, and the parts a technician checks first for each one.
| Symptom | Common causes a technician checks | Guide |
|---|---|---|
| Fan won’t turn on | Failed blower motor, fan switch, keypad or control board, loose wiring, tripped breaker | Check the breaker. If the lights work but the fan doesn’t, the problem is in the fan circuit, not the power.Possible causes a technician checks: Failed blower motor, fan switch, keypad or control board, loose wiring, tripped breaker Schedule a diagnosis |
| Weak suction or smoke not clearing | Grease-clogged filters, stuck damper in the hood or at the outside vent cap, damaged blower wheel, weak motor | Clean or replace the filters first. Saturated filters are the most common cause.Possible causes a technician checks: Grease-clogged filters, stuck damper in the hood or at the outside vent cap, damaged blower wheel, weak motor Schedule a diagnosis |
| Loud, rattling or humming fan | Loose or bent blower wheel, worn motor bearings, loose panels, damper flapping, debris in the duct | Make sure the filters are seated firmly and nothing is loose on the hood.Possible causes a technician checks: Loose or bent blower wheel, worn motor bearings, loose panels, damper flapping, debris in the duct Schedule a diagnosis |

Often, though parts can be the limiting factor. On older hoods, switches, light sockets and fan motors are the common failures, and some original parts are no longer made. A universal part can sometimes stand in. We check what is available first, and if a replacement makes more sense, we can help you choose one that fits the existing duct and cabinet.
In older houses, a new hood is sometimes connected to a long or undersized duct, or one that makes several turns through the attic. That restricts airflow no matter how strong the fan is. Check that the outside cap opens and the filters are clean. If airflow is still weak, a technician can test the blower and look at the duct path.
Yes. We serve north-central Denton, including the Bell Avenue Historic District, where homes are mostly early 20th-century Craftsman bungalows and Ranch houses, and the streets around the TWU campus. At booking, describe the hood, whether it ducts outside or recirculates, and the brand, which helps narrow the likely parts.
