OEM Carrier Contactor for Model COA0750M5H | Genuine HVAC Part

This genuine OEM Carrier contactor is the electrically-actuated switch that delivers line voltage to your compressor and condenser fan motor whenever your thermostat calls for cooling. Produced as a direct, exact-fit replacement for Carrier model COA0750M5H, it ensures solid contact closure, proper coil voltage operation, and the correct amperage rating your system was built to use — resolving the chattering, arcing, and welded contacts that commonly cause an outdoor unit to fail to start or refuse to shut off. Contactors are a high-wear item because they switch heavy current thousands of times each cooling season, so replacing yours with this OEM part restores reliable operation. The job typically takes 20-30 minutes and fits a confident DIYer or HVAC professional: disconnect power, transfer wires one at a time to the matching terminals, mount the new part, and restore power. Always verify the unit is de-energized first. As OEM-spec, it guarantees the right coil voltage and pole configuration. In stock and ships same-day when ordered before 3PM CST.

Frequently Asked Questions

Does this Contactor fit my Carrier Model COA0750M5H | Genuine HVAC Part?
Yes. This is the factory-specified OEM contactor for the Carrier Model COA0750M5H | Genuine HVAC Part. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the contactor on my Carrier Model COA0750M5H | Genuine HVAC Part?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Open condensing unit panel. Step 3: Photograph ALL wiring on the contactor. Step 4: Label each wire with tape. Step 5: Disconnect wires and remove old contactor. Step 6: Mount new contactor, reconnect wires matching your photo. Step 7: Restore power and test.
My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
