Aux 2 Unit 9 Quiz 2

Correct Answer:
C) Faulty motor starter or electrical relay

Explanation:
A defective motor starter or electrical relay can interrupt the power supply to the compressor, causing it to stop unexpectedly.

Correct Answer:
B) Low refrigerant pressure triggering the low pressure cut-out

Explanation:
A low refrigerant charge or leak can cause low suction pressure, triggering the low pressure cut-out and stopping the compressor to prevent damage.

Correct Answer:
C) High pressure trip due to condenser blockage

Explanation:
A blocked or restricted condenser can cause the pressure to rise above safe levels, triggering the high pressure cut-out and stopping the compressor.

Correct Answer:
B) Malfunctioning thermostat or pressure switch

Explanation:
A malfunctioning thermostat or pressure switch can send incorrect signals, causing the compressor to stop unexpectedly.

Correct Answer:
B) Leaking refrigerant or undercharge

Explanation:
A refrigerant leak or insufficient charge leads to low suction pressure, causing the low pressure cut-out to activate and stop the compressor to prevent damage from running under low pressure conditions.

Correct Answer:
B) Clogged condenser or poor heat dissipation

Explanation:
A clogged condenser or insufficient airflow can lead to high discharge pressure, which triggers the high pressure cut-out to stop the compressor and protect the system.
