Kohler 1039685 & 1036210 Air Blower Replacement Guide
Share
Quick answer: The Kohler 1039685 air blower (and the related 1036210) has been discontinued by Kohler, and no direct OEM replacement is available. Whirly Bros carries three aftermarket retrofit systems that restore a compatible Kohler air bath — the difference between them is where the electronic controller lives and how you'll operate the system day to day. Compatibility depends on your voltage, keypad opening, and installation space, so confirm before ordering.
Why is the Kohler 1039685 blower discontinued?
Kohler stopped manufacturing the 1039685 ProFlex air blower and its related electronics years ago, and major retailers like Build.com and FaucetDirect now list it as discontinued with no direct OEM replacement. The 1036210 blower and control kit share the same fate — both used proprietary control electronics that are no longer produced.
That doesn't mean your tub is done. It means the original part can't be replaced piece by piece anymore — you need a modern retrofit system engineered to work with the plumbing and keypad opening your tub already has.
3 replacement options, compared
All three systems below restore a compatible 120V/60Hz Kohler K-1039685 or 1036210 air-bath system. The right one depends on whether your original keypad can be safely removed, and how much control you want over massage modes.
| Separate Control Box | Integrated Control | Wireless Remote | |
|---|---|---|---|
| Blower output | 700W, heated | 750W, heated (9.5A) | 700W, heated (7.2A) |
| Controller location | Separate control box | Built into the blower | Separate wireless control box + floating remote |
| Best for | Standard installs with keypad access | Simpler wiring, fewer components | Keypad bonded to tub or unreachable |
| Wave & Pulse modes | Yes | Yes | 3 Speed Or Variable-Speed |
| Starting price | $429.99 | $429.99 | $399.99 |
Option 1: Separate Control Box + Keypad
A 700-watt variable-speed heated blower with its electronic controller kept as a separate box from the blower itself. Choose this if you want the controller mounted somewhere accessible apart from the blower, and your original keypad opening is reachable and removable.
See the Separate Control Box System →Option 2: Integrated-Control Blower
A higher-output 750-watt blower with the electronic controller built directly into the blower housing — fewer separate parts to mount in the equipment area. Good choice if you want a more streamlined install.
See the Integrated-Control System →Option 3: Wireless Remote System
A 120V, 7.2-amp, 700-watt heated blower paired with a separate wireless control box and a waterproof floating remote — no tub-mounted keypad required at all. Best choice if your original keypad is permanently bonded to the bathtub or the opening can't be safely reused. Note: this system provides on/off and speed control only — it does not include the programmed Wave or Pulse modes available on the two keypad-controlled systems above.
See the Wireless Remote System →Which one should I choose?
If your original keypad comes out cleanly and you're comfortable with a standard install, either the Separate Control Box or Integrated-Control system will work — the choice mostly comes down to whether you'd rather have one component (integrated) or split the controller out separately, and both give you full Wave and Pulse massage modes. If your keypad is stuck, damaged, or bonded into the tub deck in a way that risks cracking it during removal, the Wireless Remote system avoids that problem entirely — but keep in mind it only offers on/off and variable-speed control, not the programmed Wave/Pulse patterns.

Frequently asked questions
Does a 1039685 replacement also work for the Kohler 1036210?

No. Kohler has discontinued this part with no direct OEM replacement currently available. The options above are aftermarket retrofit systems designed to restore function using your existing tub and plumbing.
Do I need an electrician to install one of these systems?
Basic installation instructions are included with each system, but you should use a qualified installer or electrician whenever electrical work, grounding, or local code compliance is uncertain.
