K-1039685 Kohler Air Blower Replacement System
Bring your luxury air bath back to life with the K-1039685 Kohler Air Blower Replacement System from Whirly Bros. Manufactured by CG Air Systems, this complete aftermarket retrofit kit is designed to replace the discontinued Kohler K-1039685 air massage system with modern electronics, a powerful variable-speed blower, an integrated air heater, and an easy-to-use electronic keypad.
Instead of searching for obsolete individual components or attempting to repair aging electronics, this complete replacement system provides the main components needed to restore compatible Kohler BubbleMassage® air baths with dependable performance and serviceable replacement parts.
Important: This is a complete aftermarket retrofit system. It is not an original Kohler-manufactured blower assembly.
Why Upgrade Your Kohler Air Bath?
Many original Kohler air massage systems have reached an age where blower motors, keypads, control boxes, and internal electronics can begin to fail. Original replacement components may also be discontinued or difficult to locate.
This retrofit allows you to modernize the air massage system while keeping your existing bathtub.
- Complete retrofit solution: Replaces aging blower and control components as a coordinated system.
- Variable-speed operation: Adjust the airflow from gentle bubbling to stronger air massage.
- Built-in air heater: Helps reduce the cold-air sensation associated with unheated blowers.
- Modern electronic controls: Provides simple keypad operation and an automatic timed cycle.
- Serviceable replacement components: Uses currently available CG Air Systems technology.
- Clean retrofit appearance: The replacement keypad trim is designed to cover the original opening.
Complete Retrofit Kit
The components in this system are designed to operate together, helping eliminate compatibility problems that can occur when mixing old and new controls.
Kit includes:
- 700-watt variable-speed air blower
- Integrated 120-watt air heater
- Electronic control box
- Electronic keypad with trim bezel
- Communication cable
- Installation instructions
Kit contents may vary slightly as manufacturers update component designs. Contact Whirly Bros before ordering when exact component appearance is important.
Designed for the Existing Keypad Opening
One of the most important considerations when replacing a discontinued Kohler air bath system is covering the original keypad opening cleanly.
The included keypad has an approximately 2-1/2-inch square trim bezel designed to cover an original opening of approximately 1-7/8 inches. The keypad attaches using high-strength adhesive backing for a clean finished appearance without a separate oversized trim plate.
Always measure the existing opening and surrounding flat mounting surface before ordering.
Variable-Speed Air Massage
The 700-watt variable-speed blower allows you to adjust the air output to suit your preferred bathing experience. Select a lower setting for gentle bubbling or increase the airflow for a stronger air massage.
- 700-watt blower output
- Variable-speed airflow
- Electronic speed adjustment
- Quiet, efficient operation
- Automatic timed operation
Integrated Heated Air
The blower includes an integrated 120-watt air heater that gently warms the air moving through the bath system. The heater is intended to improve comfort and reduce the initial cold-air sensation at the air jets.
The air heater is not designed to heat the bathwater or replace a water heater.
Common Problems This Retrofit Can Address
A complete system replacement may be appropriate when a compatible Kohler air bath is experiencing problems such as:
- Blower does not turn on
- Keypad does not respond
- Weak or inconsistent airflow
- Intermittent blower operation
- Excessive blower noise
- Failed control box
- Failed air heater
- Discontinued original electronic components
These symptoms can also be caused by electrical, plumbing, or air-distribution problems. Proper diagnosis is recommended before ordering.

This retrofit system is intended for use as a replacement solution for compatible air massage baths associated with the following identification numbers and descriptions:
