Quality Assurance & Compliance Flashcards

Which of the following best defines 'root cause analysis' in the context of appliance service QA?

Answer: Determining the underlying reason a failure occurred to prevent recurrence

Root cause analysis investigates the fundamental reason a defect or failure occurred so corrective actions can prevent the same issue from recurring.

A service company is required to maintain records of refrigerant purchases and disposals. How long must these records typically be kept under EPA Section 608?

Answer: 3 years

EPA Section 608 requires that records related to refrigerant recovery, recycling, and sales be retained for at least three years.

During appliance service, 'torque specifications' are especially critical when:

Answer: Fastening gas line fittings and structural components to manufacturer tolerances

Torque specifications ensure gas fittings and structural fasteners are tightened correctly — under-torquing causes leaks while over-torquing can crack fittings, both creating safety and compliance hazards.

What is the primary purpose of requiring technicians to obtain customer signatures on completed service orders?

Answer: To confirm the customer acknowledges the work performed and accepts the condition of the appliance

Customer signatures on service orders serve as documented acknowledgment that the repair was performed and that the appliance was left in an agreed-upon condition.

A technician finds mold inside a washing machine drum during a service call for a different issue. Under QA best practices, the technician should:

Answer: Document the finding, inform the customer, and recommend proper remediation steps

Comprehensive quality service requires technicians to document and communicate all findings to the customer, even those outside the primary repair scope, for transparency and safety.

Which of the following would constitute a violation of appliance service compliance when handling a recalled component?

Answer: Installing the recalled part on another customer's appliance to avoid waste

Installing a component that has an active safety recall on any appliance is a serious compliance violation that creates safety hazards and legal liability.

In appliance service QA, what does 'non-conformance' refer to?

Answer: Any instance where a service output or process fails to meet established standards or specifications

Non-conformance in QA means that a service, repair, part, or procedure failed to meet the defined quality standards or specifications that the organization requires.
