OE Spec AC Pressure Transducer Switch For Mazda – ISUMO GT7219 (BBM4-61-503A)

If your Mazda's A/C is acting up—maybe the compressor isn't kicking on or the air isn't getting cold—the pressure transducer switch might be the culprit.

This is a new OE-spec replacement from ISUMO.

It's the refrigerant pressure switch that monitors the pressure in the A/C system and tells the compressor when to engage.

It's a direct replacement, crossing to the original Mazda part numbers BBM461503A and BBM4-61-503A.

The manufacturer part number is GT7219.

It's brand new in the box.

Just a heads up, there's a California Prop 65 warning, which is standard for many auto electrical parts.

A simple fix to get your A/C blowing cold again.
