OEM Carrier Defrost Control Board HK32EA007 for Model PH14NB04200GAAAA

This is the genuine OEM defrost control board (part number HK32EA007), the factory-specified replacement for Carrier PH14NB04200GAAAA heat pump systems. The defrost control board monitors outdoor coil temperature and time intervals to initiate and terminate defrost cycles automatically. When this board fails, the outdoor unit can ice over completely, causing the system to lose heating capacity, short-cycle, or lock out entirely — leaving you without heat during the coldest days of the year.

• Specs: Carrier OEM part HK32EA007 | Also cross-references 1177927 and 1173636 | Direct plug-in board replacement | Factory-calibrated defrost timing and temperature thresholds
• OEM vs Generic: This genuine Carrier board is pre-calibrated to factory defrost intervals and temperature setpoints. Aftermarket boards often use generic timing logic that leads to under-defrosting (icing) or over-defrosting (efficiency loss), shortening compressor life.
• Install difficulty: 3/5 — Disconnect power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone or camera to photograph wiring. Swap connectors one at a time to avoid mis-wiring. A licensed HVAC technician is recommended for first-time installs.
• Warranty: 1-year OEM manufacturer warranty from date of purchase. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PH14NB04200GAAAA heat pump. Also replaces legacy board numbers 1173636 and 1177927. Verify your existing board's part number against the data plate or existing board label before ordering. Not sure it fits? Contact our team — we verify fitment before you buy.
