Pick the failed part to see a typical repair range for a commercial gas or electric fryer, plus service call and same-day fees.
Last reviewed October 2026 · How we calculate estimates
Most commercial fryer repairs cost $150 to $600, and the most common failures are small parts: a pilot that won't stay lit, a thermostat that drifts, or a high-limit switch that keeps tripping. Because fryers combine gas or high-voltage power with 350°F oil, these are repairs for a licensed technician rather than kitchen staff.
| Cost breakdown | Range |
|---|
| Repair | Typical cost |
|---|---|
| Thermocouple / thermopile | $100 – $200 |
| High-limit safety switch | $100 – $250 |
| Drain valve | $125 – $275 |
| Pilot assembly or ignition system | $125 – $300 |
| Thermostat | $150 – $350 |
| Heating element (electric fryer) | $200 – $500 |
| Pressure fryer gasket and seals | $200 – $400 |
| Gas valve | $250 – $550 |
| Control board / computer controller | $300 – $600 |
| Diagnostic / service call | $75 – $150 |
| Same-day emergency premium | +$100 – $150 |

A gas fryer's pilot keeps dropping out during the lunch rush. The technician replaces the pilot assembly. With the service call, the calculator shows $200 – $450 nationally, or $220 – $500 in California. If the technician only needed to replace the thermocouple, the job drops to $175 – $350 nationally.
Thermostats, thermocouples, pilots, high-limits and gas valves are routine repairs worth making on almost any fryer. The usual replacement trigger is a cracked or leaking fry pot, or a repair that approaches half the price of a comparable new fryer. Our guide to repairing or replacing restaurant equipment walks through the math.
Each repair has its own published low-to-high range for parts and labor. The service call and same-day premium are added if you include them, and the total is adjusted by your state's BEA Regional Price Parity if you pick a state. See our methodology.
Brand matters most for controllers and pumps. Published pricing shows Frymaster minor repairs (thermopile, pilot) around $150 to $300 and gas valve or controller work around $400 to $800. Pitco high-limit and thermostat replacements run about $200 to $400, and a filter pump motor about $600 to $900.
Most commercial fryer repairs cost $150 to $600. Thermocouples and high-limit switches run $100 to $250, thermostats $150 to $350, gas valves $250 to $550, and control boards $300 to $600 or more for some brands.
The most common cause is a worn thermocouple or thermopile, which costs about $100 to $200 to replace. A dirty pilot orifice or a failing gas valve can also cause it.
Usually yes for small parts like thermostats, pilots and switches. When a fryer pot is cracked or leaking, or a repair approaches half the price of a new fryer, replacement is usually the better choice.
