The contactor is the electrically-controlled switch that delivers line voltage to your Carrier compressor and condenser fan whenever the thermostat calls for cooling. Its low-voltage coil pulls the contacts closed; when it fails you'll hear chattering or buzzing at the outdoor unit, the system won't start, the compressor or fan may run nonstop even after the call ends (welded contacts), or cooling turns intermittent as pitted, arcing contacts drop connection. Insects and debris on the contacts are a common failure trigger. Carrier contactors are specified by pole count (1 or 2 pole), contact amp rating (commonly 24–40 FLA), and coil voltage (typically 24V). Match all three to your original. This OEM contactor uses silver-alloy contacts rated to handle the unit's full-load and locked-rotor amperage. Why OEM matters here: generic contactors frequently use undersized or lower-grade contact material that pits and welds faster under a compressor's inrush current, causing repeat failures and the risk of a compressor stuck energized. Genuine Carrier contactors carry the correct contact mass and coil rating, making clean, full closures over tens of thousands of cycles. Install difficulty: 2/5. Tools: 1/4" and 5/16" nut drivers, insulated screwdriver, needle-nose pliers, and a multimeter. SAFETY: shut off the disconnect AND the breaker to the condenser before touching anything — 240V line voltage is present at the contactor. Discharge the nearby run capacitor as well. Photograph or label every wire before removal so reassembly is exact. Ships same business day from our stocked warehouse on orders before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.
This part is compatible with Carrier model 07EB033911. Always verify the part number against your unit's data plate before ordering.
OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.
Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.
