Commercial fryer being repaired on a Jacksonville restaurant line
Quick answer

Commercial appliance repair in Jacksonville covers restaurant gas ranges, convection ovens, fryers, griddles and commercial dishwashers. Common failures are pilots and thermocouples, gas valves, thermostats, igniters, heating elements and wash or rinse pumps. We diagnose on site, repair what we can that visit and order brand parts when needed.

Restaurant equipment fails at the controls

Commercial cooking equipment is simple and heavy. Most failures are in the gas and temperature controls: pilots that will not stay lit, thermocouples, gas valves, thermostats and high-limit switches. Those are quick to test and usually quick to replace once the right part is in hand.

Commercial dishwashers fail at the pumps, the heaters that hold wash and rinse temperatures, the chemical dispensing and the door switches. Holding the right final rinse temperature or sanitizer concentration matters for inspections, so we check those numbers at every dish machine call.

The jobs this page covers

01

Commercial Range and Oven Repair

Restaurant ranges use standing pilots or spark ignition, with thermocouples or flame sensors proving each burner and oven. A pilot that will not stay lit is usually a thermocouple; an oven that will not hold temperature is often a thermostat out of calibration or a failing gas valve. Convection ovens add a blower motor and its controls. We test, calibrate thermostats where possible, replace failed parts and leak-test every gas joint we touch before handing the equipment back to the kitchen.

Commercial Dishwasher Repair

High-temperature machines rely on a booster heater to reach final rinse temperature; low-temperature machines rely on chemical sanitizer. When the wash or rinse temperature drops, or sanitizer is not dispensing, the machine may pass dishes that do not meet code. We check the wash and rinse temperatures, heaters, pumps, fill valves, door switches and the dispensing lines, replace failed parts and confirm the readings before the machine goes back into service. We write the final readings down for your records, since inspectors ask for them.

03

Fryer and Griddle Repair

Gas fryers fail at the pilot, thermopile, gas valve and high-limit, and electric fryers at the elements and contactors. A fryer that will not heat or keeps tripping the high-limit is taken out of service until it is fixed. Griddles have the same pilot and thermostat parts plus uneven plates from warped tops. We repair the controls, check the temperature against a probe and leak-test the gas connections and the quick-disconnect hoses that move with the equipment. A worn hose or a missing restraint cable gets flagged.

Restaurant kitchens around Jacksonville

From busy restaurant corridors to small neighborhood cafes and beach restaurants, commercial kitchens around Jacksonville run long hours in hot rooms, which is hard on thermostats, fans and gas controls. We schedule commercial calls around service when we can, and we tell you up front whether a repair can be finished today or needs a brand part ordered.

Cost

What commercial repairs cost

Commercial repairs are quoted after diagnosis. Controls, pilots and thermostats are usually modest repairs; brand-specific boards and pumps cost more and may be ordered.

  • Equipment type. Fryers, ranges and dish machines differ.
  • Brand parts. Commercial brands are often ordered.
  • After-hours timing. Visits outside business hours can carry a fee.
  • Number of units. Several units in one visit are diagnosed together.

No flat price over the phone. We price after the diagnosis, part and labor separately, so you can decide before any work starts.
