Kitchen Exhaust Hood Repair Needs in Frisco Restaurants and Kitchens

Rooftop exhaust fans on restaurant buildings at The Star in Frisco, in the Stonebriar Centre area and in the Downtown Rail District all face the same North Texas conditions: full sun, high summer heat, wind and dust. Belts glaze and slip, bearings wear and motors run hot. A squealing belt, a fan that wobbles or sounds rough, or grease pooling around the curb on the roof are all reasons to call before the fan fails in the middle of service.

Problems inside the building often trace back to the roof. When the exhaust fan slows or the make-up air unit is off, the hood stops capturing smoke, burner flames lean or go out, and air rushes in around the front entrance. In a hot Frisco kitchen, staff sometimes switch off make-up air to stay cooler, which makes the imbalance worse. Clean hood filters on a regular schedule. Suppression system inspections are handled by a fire protection company on their own schedule, while fan motor and electrical repairs should go to a technician.

Common problems

What’s Wrong With Your Commercial Kitchen Exhaust Hood?

The kitchen exhaust hood problems we see most often, and the parts a technician checks first for each one.

SymptomCommon causes a technician checksGuide
Hood not pulling smoke or weak draftBroken or slipping fan belt, failed exhaust fan motor, clogged grease filters, grease-loaded fan wheel, make-up air imbalance
Check whether the exhaust fan on the roof is spinning and the grease filters are clean.

Possible causes a technician checks: Broken or slipping fan belt, failed exhaust fan motor, clogged grease filters, grease-loaded fan wheel, make-up air imbalance

Schedule a diagnosis
Exhaust fan won’t runFailed motor, broken belt, tripped breaker, starter or contactor fault, switch or control fault, thermal overload
Check the hood switch and breaker. If the hood lights work but the fan doesn’t, the fault is in the fan circuit.

Possible causes a technician checks: Failed motor, broken belt, tripped breaker, starter or contactor fault, switch or control fault, thermal overload

Schedule a diagnosis
Squealing, rattling or vibration on the roofWorn or loose belt, misaligned pulleys, dry or failing bearings, grease buildup unbalancing the fan wheel
A squeal that starts at fan startup is usually the belt. Grinding usually means bearings.

Possible causes a technician checks: Worn or loose belt, misaligned pulleys, dry or failing bearings, grease buildup unbalancing the fan wheel

Schedule a diagnosis
Doors hard to open or smoke drifting into the dining roomMake-up air unit not running or undersized, negative building pressure, exhaust and supply out of balance
Notice whether doors whistle or pull shut. That points to negative pressure from missing make-up air.

Possible causes a technician checks: Make-up air unit not running or undersized, negative building pressure, exhaust and supply out of balance

Exhaust Fan Down During Service?

Without exhaust, smoke and heat build up fast and cooking under the hood may not be safe. These steps help while we diagnose the problem. After-hours and emergency service is available at an additional charge in Frisco.

The most common cause is a broken or slipping belt on the rooftop fan, which leaves the motor running while the fan wheel slows or stops. A tripped motor overload or a failed motor are the next likely causes. Shut down cooking under the hood if smoke is not being captured, and call for service with what you heard or saw on the roof.

Yes. We work on upblast exhaust fans, make-up air units, belts, pulleys, bearings, motors and controls for restaurants at The Star, around Stonebriar Centre and along the Dallas North Tollway and Preston Road. Describe the roof access and whether the fan sounds rough, spins slowly or has quit entirely, and we will plan the visit and parts around that.

It depends on the building. Some downtown restaurants reach the roof by an interior hatch and others by an exterior ladder, and that affects how a fan repair is planned. Let us know which you have, along with the hood size and the symptoms. Main and Elm streets were rebuilt during the city’s redevelopment, so mention where a service vehicle can park.
