NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) requires cleaning frequency based on cooking volume: monthly for solid fuel cooking (wood, charcoal); quarterly for high-volume cooking (24-hour operations, charbroiling); semi-annually for moderate-volume cooking; and annually for low-volume cooking (pizzerias, churches, seasonal businesses). Your local fire marshal may have additional requirements. Failure to comply can void your fire suppression system coverage.

Commercial oven repair costs range from $200 to $2,000+ depending on the issue. Common repairs: igniter replacement $200-$400, thermostat or temperature probe $250-$500, gas valve replacement $350-$700, control board $600-$1,500, heating element (electric) $200-$600. Diagnostic fees of $100-$200 are typically applied to the repair total.

Signs of compressor problems: unit not reaching temperature despite running constantly, compressor making loud knocking or grinding sounds, compressor starting and stopping rapidly (short cycling), compressor not starting at all, or high pressure shutdowns. Compressor failure is typically the most expensive refrigeration repair. Early diagnosis can sometimes allow for less costly repairs — don't wait if you hear unusual compressor noises.
