This is the replacement touchpad and control board assembly for 18" PolarCool evaporative coolers built before 2014. If your fan's speed controls or pump switch have quit working, this pre-mounted control plate restores full operation without you having to source separate parts.
This control plate is a genuine PolarCool replacement component built for facilities running older 18" evaporative coolers in warehouses, outdoor spaces, and industrial cooling setups. It's a direct-fit swap, not a universal part, so model-year verification matters before you order. 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
- Fits 18" PolarCool evaporative cooling fans manufactured prior to 2014 only.
- Kit includes touchpad faceplate with control board pre-mounted — no separate board sourcing needed.
- Controls 10 variable fan speeds and water pump operation.
- NOT compatible with motor SKU 3017-0050.
- Not intended for 18" PolarCool models manufactured 2014 or later — confirm your unit's build year before purchase.
Swapping a control plate on a wall-mounted evaporative cooler often means working with wiring harnesses that have been baked and stiffened by years of heat and moisture cycling. Forcing brittle connectors back into place is the fastest way to crack a pin or create an intermittent short that shows up months later as erratic speed cycling. Before you reconnect anything, inspect each harness connector for cracked plastic or corroded pins, and use a dielectric contact cleaner on the terminals rather than forcing a dry connection. Always disconnect power at the source per standard electrical lockout practice before touching the control board, and confirm the unit is fully de-energized with a multimeter before reassembly. This keeps you compliant with basic electrical safety practice and prevents a callback for a control plate that "never worked right" out of the box.
Key Benefits
- Genuine PolarCool replacement component built for direct fitment on pre-2014 18" units.
- Pre-mounted control board reduces assembly steps and service time.
- 10 variable speed settings give you finer airflow control than a basic on/off switch.
- Restores water pump control alongside fan speed operation.
- Suited to warehouse, industrial, and outdoor cooling applications where these coolers see heavy use.

FAQ
Does this control plate fit any 18" PolarCool fan?
It fits 18" PolarCool evaporative cooling fans manufactured prior to 2014. Verify your model year before ordering, since post-2014 units use a different control plate.
Is the control board already mounted on the faceplate?
Yes. The kit ships as a complete touchpad faceplate with the control board pre-mounted, so you install it as one assembly.
How many fan speeds does this control plate operate?
It provides access to 10 variable fan speeds plus water pump control.
Will this work with motor SKU 3017-0050?
No. This control plate is explicitly not compatible with motor SKU 3017-0050.
Do I need to disconnect power before installing this?
Yes. Disconnect power before installation, follow the manufacturer's wiring and mounting guidelines, and test all speed settings and pump operation once it's wired in.
