OEM Carrier Defrost Control Board CESO130076-00 for Model PH3PPA036000AA

This OEM defrost control circuit board is the factory-specified replacement for the Carrier PH3PPA036000AA heat pump. The control board serves as the operational brain of your unit — it continuously monitors defrost sensors, safety switches, and system inputs, then coordinates and executes every stage of the heating and cooling cycle by directing voltage to the appropriate components. When this board fails, you may experience a complete system lockout, erratic or absent defrost cycles, a unit that runs in heating mode but fails to defrost the outdoor coil, or a heat pump that simply will not respond to thermostat calls. Replacing a failed defrost control board with the correct OEM part restores factory-programmed logic and timing sequences, ensuring safe, reliable, and efficient operation.

• Specs: OEM Part # CESO130076-00 (superseded by HK32EA008) | Carrier/Bryant/Payne defrost control circuit board | Designed for R-22 and compatible heat pump platforms | Factory-matched control logic and terminal layout
• OEM vs Generic: This is a genuine OEM Carrier board with factory-programmed defrost timing and sensor thresholds. Aftermarket boards may use approximate logic parameters, which can cause premature or missed defrost cycles, leading to coil icing, reduced efficiency, and compressor strain.
• Install Difficulty: 3/5 — Disconnect power at the breaker before handling any control board. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, smartphone (to photograph all wiring before disconnection), and a multimeter to verify 24V control circuit before powering up. Take care to seat all harness connectors fully and in the correct orientation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.
