We understand that every hour of downtime impacts business operations, so we provide prompt, reliable service to keep your commercial appliances running safely and efficiently. Below are the most common types of commercial appliances we repair and the typical issues business owners encounter.
Commercial Refrigerator and Freezer Repair
Refrigeration is the heart of any food service operation. Top Appliance Repair services all commercial refrigeration systems, including upright refrigerators, reach-in coolers, walk-in units, under-counter models, prep tables, and freezers.
We service major brands such as True, Traulsen, Sub-Zero, Beverage-Air, Turbo Air, Kelvinator, and Continental. The most common problems include fluctuating temperatures, excessive frost buildup, leaking water, or units running constantly.
In many cases, a refrigerator that fails to cool properly has a defective compressor, clogged condenser coils, or low refrigerant levels. Frost buildup along the evaporator panel indicates defrost system failure involving the heater, thermostat, or control timer. Condensation or water on the floor usually points to a blocked drain tube.
Noisy compressors, fan motor failure, and worn door gaskets are also frequent issues in high-traffic commercial kitchens. Ice buildup around coils can prevent proper airflow, reducing cooling capacity.
In wine bars and specialty stores, Sub-Zero and True refrigeration systems may develop control board or temperature sensor faults due to constant operation. Regular maintenance prevents these breakdowns, but when problems arise, our technicians provide rapid diagnosis and repair to minimize downtime.
Commercial Oven, Range, and Cooktop Repair
Restaurants and bakeries depend on reliable ovens and cooktops for daily operation. Top Appliance Repair provides complete commercial oven and range repair throughout San Francisco. We service gas, electric, and convection models from brands such as Wolf, Viking, Garland, Thermador, Dacor, and Blodgett.
Common issues include uneven cooking, temperature inaccuracy, burners not igniting, or ovens not heating at all. Gas ovens that fail to light typically have worn igniters, faulty safety valves, or clogged burners. Electric ranges with inconsistent heating often have damaged elements or control board faults.
In busy kitchens, grease and debris can clog ignition systems, causing constant clicking or delayed ignition. Overheating or tripped circuit breakers may signal defective thermostats or shorted heating elements.
Convection ovens sometimes lose fan function, resulting in uneven baking or slow preheat times. Viking and Wolf units may experience faulty temperature sensors or control relay board failures.
For cooktops and griddles, common repairs include replacing igniters, recalibrating thermostats, and servicing gas regulators. Regular inspection prevents hazards such as gas leaks or overheating elements.
Top Appliance Repair ensures every commercial range, oven, or cooktop in San Francisco operates safely and at precise temperatures for consistent cooking results.
Commercial Dishwasher Repair
Commercial dishwashers must perform flawlessly under constant use. Top Appliance Repair services all types, including under-counter, conveyor, and high-temperature models from Hobart, Jackson, Miele, Bosch, and CMA.
The most common problems include poor cleaning, dishes coming out wet, failure to fill or drain, and water leaks. Many issues arise from blocked filters, worn drain pumps, or malfunctioning heating elements. Control panel failures can stop cycles mid-run, while broken door seals cause leaks onto the floor.
Hobart and CMA dishwashers often require drain valve or thermostat replacement. Bosch and Miele commercial models can display error codes related to sensors or heaters. Restaurants that use hard water often experience scale buildup that reduces efficiency.
In San Francisco’s fast-paced kitchens, even small dishwasher failures can slow service. Our technicians restore performance by repairing pumps, valves, and temperature sensors, ensuring every load meets hygiene and efficiency standards.
Commercial Washer and Dryer Repair
Hotels, spas, salons, and laundromats across San Francisco depend on reliable laundry appliances. Top Appliance Repair services all commercial washers and dryers, including units from Speed Queen, Whirlpool, Maytag, GE, LG, and Electrolux.
Common washer problems include failure to spin, slow draining, leaks, and vibration during spin cycles. Commercial units may stop mid-cycle due to control board faults or power surges. Drain pumps, water inlet valves, and door locks are frequently replaced components.
Commercial dryers often face heating issues, long dry times, or drum noise. Overheating can occur if vents are clogged or thermostats fail. Electric dryers with no heat may need heating element or thermal fuse replacement, while gas dryers may require new igniters or gas valves.
Speed Queen and Maytag machines are built for heavy use but can develop worn bearings or belt slippage under constant operation. Regular maintenance, including lint trap cleaning and inspection of hoses, helps prevent major breakdowns.
Top Appliance Repair provides dependable washer and dryer repair for all San Francisco commercial clients, ensuring consistent performance and safety.
Commercial Ice Machine and Beverage Equipment Repair
Ice makers and beverage dispensers are critical for restaurants, bars, and convenience stores. Top Appliance Repair repairs all commercial ice machines, soda systems, and water dispensers in San Francisco.
We service brands such as Manitowoc, Scotsman, Hoshizaki, U-Line, and True. Common problems include ice not forming, slow production, leaking water, or machine freezing over. These issues often result from mineral buildup on the evaporator plate, low refrigerant, or clogged water filters.
If your ice machine produces cloudy or small cubes, it may have scale deposits or temperature regulation problems. Leaks under the unit indicate blocked drains or cracked tubing. Loud operation usually comes from worn fan motors or pumps.
U-Line and Hoshizaki ice machines sometimes display error codes linked to water inlet valves or sensors. Regular cleaning and maintenance reduce these issues, but professional service is essential for long-term reliability.
Commercial Wine Cooler and Display Refrigerator Repair
Many restaurants, bars, and hotels in San Francisco rely on specialized refrigeration for wine and beverages. Top Appliance Repair provides professional repair for all commercial wine coolers and display cases from Sub-Zero, Liebherr, Vinotemp, True, and Thermador.
Common problems include temperature fluctuations, condensation inside glass doors, and excessive noise. These typically result from faulty thermostats, evaporator fans, or control boards. Humidity sensors may fail, leading to dry corks or overly moist environments.
Wine coolers that display incorrect temperature readings often have defective thermistors or power supply issues. Frost or water buildup at the base indicates blocked drains. In dual-zone units, uneven cooling between compartments usually means one fan motor or compressor section has failed.
Because wine and beverage coolers store valuable inventory, prompt service is critical. Top Appliance Repair restores cooling precision, calibrates sensors, and replaces defective components to keep products perfectly stored at serving temperature.
Commercial Range Hood and Ventilation System Repair
Effective ventilation is vital for maintaining air quality and fire safety in commercial kitchens. Top Appliance Repair services all major range hood and exhaust systems from brands like CaptiveAire, Viking, Thermador, and Wolf.
Common problems include reduced suction, excessive noise, vibration, or motor failure. Grease buildup in filters and ducts can cause overheating and electrical short circuits. Control panels or speed switches sometimes stop responding due to heat exposure.
Commercial range hoods operating in high-volume restaurants may develop bearing wear or fan imbalance over time. Regular inspection prevents breakdowns and ensures compliance with safety codes.
Top Appliance Repair provides motor replacement, fan blade cleaning, switch repair, and full ventilation diagnostics for all commercial hood systems in San Francisco.
