Climatemaster 33B0002N01, Thermal Expansion Valve, Bbive, 2Ga, Bp15, TXV, 30″ Capillary

Climatemaster 33B0002N01 — Bi-Flow Thermal Expansion Valve, BP15, 30 Inch Capillary

The Climatemaster 33B0002N01 is a genuine OEM bi-flow thermal expansion valve,
carrying the 2GA and BP15 designations, supplied with a 30 inch capillary tube. A TXV meters
liquid refrigerant into the evaporator and adjusts that flow to hold a target superheat, so the
coil stays fully fed without flooding the compressor with liquid.

About this part

Bi-flow valves matter on heat pumps because refrigerant has to travel in both directions as
the unit switches between heating and cooling. A bi-flow TXV meters in one direction and allows
free flow in the other, which is why a standard cooling-only expansion valve is not an
acceptable substitute here.

Symptoms of a failed TXV include low suction pressure with high superheat, frost forming at
the valve outlet, or a coil that only partially cools. Before condemning the valve, verify the
charge, confirm the sensing bulb is clean and properly strapped and insulated, and make sure the
filter drier is not restricted. Match the full part number when ordering, since ClimateMaster
uses several BP-series valves sized to different capacities.
