Fryers work hard and show neglect quickly. Poor care means shorter oil life, inconsistent food and more breakdowns. Use this routine as a starting point, and always follow the manual for your model, since cleaning products and procedures differ by manufacturer.
Safety first: hot oil causes serious burns. Turn the fryer off and let the oil cool to the temperature your manual specifies before draining or filtering.
Every shift
- Skim crumbs from the oil regularly during service so they don't burn and break down the oil.
- Filter the oil after service using the built-in filter or a portable filter machine.
- Wipe down the exterior and surrounding surfaces with a suitable degreaser before grease bakes on.
Weekly
- Boil out the fryer using a boil-out product and the procedure in your manual, then rinse and dry it thoroughly before adding fresh oil. Water left in the vat can make hot oil splatter violently.
- Inspect the baskets. Replace any that are bent or have broken welds.
Monthly
- Check the oil temperature with an accurate probe thermometer and compare it with the fryer's setting. If they don't match, arrange for calibration.
- Inspect door hinges, handles and the area around the fryer for wear or grease buildup.
- Check the vat and heating elements for pitting or heavy carbon buildup.
Quarterly
- Have a qualified technician inspect gas connections, burners, the pilot if your fryer has one, and safety controls, including the high-limit thermostat. Leave safety-control testing to the technician.
- Replace filter media and cartridges on the schedule your manufacturer recommends.
- Review oil purchases. A sudden increase can point to a fault, a leak or a change in kitchen habits.
When to call for service
- The pilot won't stay lit.
- The oil foams heavily even after a fresh change.
- The temperature swings widely or won't hold.
- The fryer shuts off unexpectedly.
If you ever smell gas, shut off the gas supply if it is safe to do so, leave the building, and call your gas utility's emergency line or 911 from outside.
