CFESA Food Equipment Maintenance 2

Question 1

What NSF standard governs the design, construction, and material requirements for commercial food equipment?

Accepted Answer

NSF/ANSI 2

Answer

NSF/ANSI 2 covers the minimum food zone design and fabrication requirements for commercial food equipment to ensure cleanability and sanitation.

Question 2

A commercial steam kettle is producing inconsistent temperatures. The first component to check is:

Accepted Answer

The jacket pressure gauge and steam inlet pressure

Answer

Inconsistent steam kettle temperatures are often caused by low or fluctuating steam supply pressure; checking the jacket pressure gauge and inlet pressure is the first diagnostic step.

Question 3

What is the primary purpose of a grease trap on commercial cooking equipment drain connections?

Accepted Answer

Collect fats, oils, and grease to prevent sewer system blockage

Answer

Grease traps intercept fats, oils, and grease (FOG) from wastewater before it enters the sewer system, preventing blockages and regulatory violations.

Question 4

When calibrating a commercial convection oven thermostat, a technician finds it reads 25°F high. The correct action is:

Accepted Answer

Adjust the calibration screw per manufacturer specification to correct the offset

Answer

Most commercial oven thermostats have an adjustment screw that allows the technician to calibrate the setpoint to match actual oven temperature.

Question 5

A commercial refrigerator evaporator fan motor runs but the unit is not maintaining temperature. After checking refrigerant charge, the next item to inspect is:

Accepted Answer

The evaporator coil for ice blockage and defrost system operation

Answer

An evaporator coil blocked with ice restricts airflow and heat transfer; a faulty defrost system is a common cause of inadequate cooling despite a properly charged system.
