This is a replacement 2-position terminal block for older PolarCool evaporative air coolers that use a removable terminal block on the circuit board. If your control circuit has lost connection or the original block has failed, this part restores the electrical connection without replacing the whole control board.
This terminal block is built for maintenance teams servicing older PolarCool portable evaporative air coolers, warehouse cooling systems, and swamp coolers with removable terminal block circuit boards. It gives you a direct-fit way to restore a failed control circuit connection instead of sourcing a full replacement control board. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fitment & Requirements
- 2-position terminal block, removable plug-in design.
- Fits older model PolarCool evaporative cooling fans and industrial air coolers that use a removable terminal block circuit board.
- Does NOT resolve failures caused by a damaged circuit board connector - a new control board is required in that case.
- Not a universal part: verify terminal block compatibility with your specific circuit board model before ordering.
The technical friction with terminal block swaps is misaligned or loose wire seating during reinstallation, which can cause intermittent control failures or arcing at the connector. Prevent this by inspecting the circuit board connector for pin damage or corrosion before plugging in the new block, and confirm each wire is fully seated per the original wiring configuration - a loose terminal is a common repeat-failure callback. Use a small flathead or terminal screwdriver sized to the block's screw terminals to avoid stripping them, and verify each connection with a light tug test after tightening. Always disconnect power and follow lockout/tagout procedures, and confirm your finished wiring meets applicable electrical code requirements for control circuit connections before re-energizing the unit.
Key Benefits
- Removable design allows for straightforward replacement if connections fail.
- Restores control circuit function without requiring a full control board replacement in many cases.
- Direct-fit replacement for compatible PolarCool circuit boards with terminal block connectors.
- Durable construction intended for reliable performance in industrial air coolers and warehouse cooling systems.
- Useful stock item for maintenance inventories and service kits covering older PolarCool equipment.

Compatibility & Fitment
- Compatible with older model PolarCool evaporative cooling fans and industrial air coolers using a removable terminal block circuit board.
- Suitable for warehouse cooling, outdoor cooling, portable evaporative air coolers, swamp coolers, and commercial cooling applications using this circuit board style.
- NOT compatible if the circuit board connector itself is damaged - that condition requires a replacement control board, not this terminal block.
- NOT a confirmed fit for newer PolarCool models that do not use a removable terminal block circuit board; verify your unit's board style before ordering.

FAQ
Will this terminal block fit any PolarCool cooler?
No. It fits older model PolarCool evaporative cooling fans and industrial air coolers that use a removable terminal block circuit board. Verify your circuit board model before ordering.
What if the circuit board connector is damaged?
If the connector on the circuit board is damaged, this terminal block replacement will not resolve the issue. You will need to contact PolarCool about a replacement control board.
Does installing this part require any special tools?
No special tools are required. It is a plug-in design, but you should disconnect power and follow lockout/tagout procedures before working on the circuit board.
How many terminal positions does this block have?
This part has 2 terminal positions for control circuit wiring.
Can this replace an entire control board?
In many cases, yes - replacing just the terminal block restores proper electrical connection without needing a full control board replacement, as long as the circuit board connector itself is not damaged.
