Overview

This genuine OEM defrost control board (Tempstar part number 1086070) is the brain of the defrost cycle on the TCH260AKA1 heat pump. It monitors outdoor coil temperature and run time, then commands the reversing valve and energizes the auxiliary heat to clear frost and ice from the outdoor coil during heating operation. A failed defrost board leaves the outdoor unit iced over, robbing the system of heating capacity and risking compressor damage. Because it coordinates the reversing valve, fan, and defrost timing, it is a critical control component for reliable winter heat-pump performance.

Frequently Asked Questions

Does this Control Board fit my Tempstar TCH260AKA1 — Heat Pump | Ships Today?

Yes. This is the factory-specified OEM control board for the Tempstar TCH260AKA1 — 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 TCH260AKA1 — 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.
