Overview

This is a genuine OEM defrost control board (part #1086070) for the Tempstar TCH230AKAA heat pump. The defrost board is the brains of the outdoor unit: it monitors the defrost thermostat and run time, decides when ice has built up on the outdoor coil, and runs a defrost cycle by energizing the reversing valve and pausing the outdoor fan until the coil clears. It also sequences the contactor and compressor and carries time-delay logic to protect the compressor. When the board fails, the heat pump may ice over and never defrost, defrost constantly, fail to start the compressor, or lose 24V output to the reversing valve and contactor.

Frequently Asked Questions

Does this Control Board fit my Tempstar TCH230AKAA — Heat Pump | Ships Today?

Yes. This is the factory-specified OEM control board for the Tempstar TCH230AKAA — Heat Pump | Ships Today. 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 control board on my Tempstar TCH230AKAA — Heat Pump | Ships Today?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this control board compatible with Bryant or Payne too?

Many Tempstar 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 Tempstar control board?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
