🛠️ HVAC Depot Pro Tip

The 49W62 is a complete replacement kit, not just the bare reversing valve.

The actual reversing valve included in the kit is:

Valve: 100145-09
Valve Cat #: 42W59

The complete kit is:

Kit Cat #: 49W62
Kit Part #: 603113-01
Solenoid: 24 VAC
Connections: 1/2" discharge / 7/8" suction-vapor

This distinction is useful when a customer is searching for either 49W62, 603113-01, 42W59, or 100145-09.

Before ordering, verify the outdoor unit model, original valve configuration, tubing sizes, refrigerant application, solenoid voltage, and complete equipment serial number.
