EPA Section 608 Universal Certification ExamType II (High-Pressure Appliances)Medium
Which of the following is considered a 'major repair' on a high-pressure appliance under EPA Section 608 regulations, triggering specific recovery and evacuation requirements?
- AAdding refrigerant due to a minor leak.
- BReplacing a compressor or evaporator coil.
- CReplacing a faulty thermostat.
- DCleaning the condenser coil.
Show answer & explanationAnswer & explanation
Correct answer: B. Replacing a compressor or evaporator coil.
Under EPA Section 608, a 'major repair' is defined as any repair that involves the removal of the compressor, evaporator, condenser, or auxiliary heat exchanger. These repairs require more stringent recovery and evacuation standards.
Why the other options are wrong
- A. Adding refrigerant (topping off) due to a minor leak is considered a service activity, not a major repair, although the leak itself must be repaired.
- C. Replacing a thermostat is a minor repair and does not typically involve opening the sealed refrigerant circuit.
- D. Cleaning a condenser coil is routine maintenance and does not involve breaking into the refrigerant circuit.
Major Repair Definition (608)
Any repair to a refrigeration appliance that involves the removal of the compressor, condenser, evaporator, or auxiliary heat exchanger.
- Triggers higher recovery/evacuation standards.
- Distinguishes from minor repairs/maintenance.
- Applies to all pressure categories of appliances.
Memory trick: Major repair means touching the 'BIG 4': Compressor, Evaporator, Condenser, Heat Exchanger!
