LG QV308PNA Rotary AC Compressor 18,000 BTU 1.5 HP R22 – Replaces QV308PMA

LG QV308PNA is an R22 rotary air conditioner compressor used in split air conditioner outdoor units. It belongs to the 18,000 BTU class (approximately 18,400 BTU/h), has a power of 1.5 HP and operates on 220–240 V 50 Hz single-phase mains. It has internal thermal protection inside the shell.

Can It Be Used in Place of the QV308PMA?

Yes. QV308PNA is the new code of the QV308PMA model. According to LG's model coding:

• Q — refrigerant R22
• V — V body (Φ132 mm)
• 308 — displacement 30.8 cm³/rev

The two models are identical in these three values; the second-to-last letter in the code (M → N) indicates a version change. When replacing, compare the connection directions and foot hole spacing of the old compressor with the new one.

Label Values

• 220–240 V ~ 50 Hz 1PH — single-phase mains supply.
• LRA 43 — locked rotor (starting) current 43 A. It is taken into account when selecting fuses and contactors.
• Thermally Protected — internal thermal protection that stops the compressor in case of overheating.
