This is the touchpad and control board replacement for the Zone 11K 36" gray rotomolded plastic evaporative cooler. If your fan speeds or pump control have stopped responding, this kit restores that function without replacing the whole unit.
The 6450-6057 control plate is built to factory-standard specifications for the Zone 11K 36" gray rotomolded plastic cooler line. It uses a plug-and-play design, so you are replacing a failed touchpad/board assembly rather than rewiring the unit. 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 Zone 11K 36" gray rotomolded plastic evaporative coolers only.
- Includes touchpad faceplate with control board pre-mounted — single-assembly installation.
- Touchpad provides 10 variable fan speeds plus pump control.
- Touchpad label color is typically blue, matching the original factory part on these units.
- Does NOT fit 36" powder-coated black models.
- Does NOT fit 36" stainless steel models.
- Does NOT fit Pro series units.
Control plate swaps on rotomolded coolers often fail on the first power-up because a wire connector was reseated loosely or a locating tab was forced during removal, leaving a gap that lets moisture into the board housing over time. Before you button up the panel, verify every plug connection clicks fully home and confirm the faceplate seats flush against the cabinet with no standing gap — a flush seal keeps splash water off the control board and prevents corrosion-driven failures down the road. Use a small flat driver to release the original retaining clips rather than prying with force, which avoids cracking the rotomolded housing around the mounting points. Always disconnect power at the source before removing the old assembly and confirm proper operation only after power is restored, consistent with standard electrical lockout practice for appliance servicing.
