Replacement Balboa Water Group 30352 Temperature Sensor with 96-Inch Cable and 3/8-Inch Bulb, 12 Month Warranty & USA Support

Restore accurate water temperature monitoring in your compatible hot tub or spa with the Wholesale Sensors Replacement for Balboa Water Group 30352 Temperature Sensor with 96-Inch Cable and 3/8-Inch Bulb. Engineered as a perfect OEM-style replacement, this sensor is designed to meet or exceed original functional specifications while providing dependable temperature feedback to compatible Balboa spa control systems.

The Balboa 30352 is a water temperature sensor designed primarily for select Balboa Value and LE control systems. It features a 96-inch cable, 2-inch long sensor bulb with a 3/8-inch diameter, two-wire construction, and a 2-pin electrical connector. SpaCare

Unlike a high-limit sensor that primarily monitors potentially excessive heater temperatures, the 30352 reads spa water temperature. Balboa documentation specifically describes this sensor as a 96-inch, 3/8-inch diameter sensor that reads the water temperature. www.slideshare.net

Replacement for Balboa 30352

This Wholesale Sensors component is designed as an aftermarket replacement for Balboa Water Group 30352.

Documented replacement and cross-reference numbers include 30352, 30352KIT, 2600-022, 612723, 9711-100, and 5-60-8008. Some catalogs also identify 10966 and BB/BAL/BWG variations of the 30352 number. Spa Parts Plus Ltd.

The Wholesale Sensors product is an aftermarket replacement and is not represented as a genuine Balboa Water Group component.

96-Inch Cable and 3/8-Inch Temperature Bulb

The 30352 configuration is designed with a 96-inch lead, providing approximately eight feet of cable for routing between the temperature sensing location and the compatible spa control system.

The sensor bulb measures approximately 2 inches long and 3/8 inch in diameter. The electrical connection uses a 2-wire, 2-pin configuration. SpaCare

These specifications are important when identifying the correct replacement. Balboa has produced multiple spa sensors with similar appearances but different bulb diameters, cable lengths, connector configurations, and intended control systems.

For example, Balboa 30298 is a different high-limit sensor with a 1/4-inch diameter bulb and 31-inch cable. Customers should therefore identify the replacement by its part number and specifications, rather than appearance alone. SpaCare

Balboa Value and LE System Compatibility

The 30352 is specifically documented as a temperature sensor for Balboa Value 1000/2000LE systems. Spa Parts Plus identifies the component as a temperature sensor for Balboa Value 1000/2000LE systems, while multiple spa-parts catalogs describe it as a Value/LE temperature sensor. Spa Parts Plus Ltd.

Documented applications include select:

Balboa Value 1000 systems
Balboa Value 2000LE systems
Balboa LE systems
Dynasty Spas using the 30352 configuration
HS200 systems
HS55 systems

The HS200 and HS55 applications are specifically documented by a hot tub parts supplier for the 30352 temperature sensor. Hot Tub Parts

Because Balboa control systems can use different sensors even when their equipment appears similar, always verify the original 30352 part number, 96-inch cable length, 3/8-inch bulb diameter, and 2-pin connector before ordering.

Important Compatibility Information

Multiple North American spa-parts catalogs specifically identify 30352 as intended for non-M7 Value/LE systems. Spaparts123

There is some conflicting aftermarket documentation online regarding certain early M7 configurations. For this reason, the safest way to determine compatibility is to match the original sensor’s 30352 part number and physical/electrical specifications, rather than assuming compatibility solely from the name of the spa control system.

Do not substitute another Balboa temperature or high-limit sensor simply because the connector or probe looks similar.

Accurate Spa Water Temperature Monitoring

The 30352 provides temperature information to the compatible spa control system.

Balboa documentation identifies the 30352 as the sensor that reads the water temperature in Value and 2000LE applications. www.slideshare.net

Accurate temperature feedback allows the spa control system to determine when heating is required and when the desired water temperature has been reached.

If the temperature sensor becomes inaccurate, electrically open, damaged, or disconnected, the control system may receive incorrect information about actual spa water temperature.

This can interfere with normal heating performance and temperature regulation.

Helps Correct Temperature and Heating Problems

A faulty temperature sensor may contribute to symptoms such as:

Incorrect spa temperature readings
Displayed temperature does not match actual water temperature
Spa water becoming warmer or cooler than expected
Unstable heating behavior
Intermittent temperature readings
Failure to maintain the selected temperature
Temperature sensor-related control problems

A properly matched replacement sensor can restore accurate temperature feedback when testing confirms the original 30352 has failed.

However, these symptoms do not automatically mean the sensor is defective.

Similar heating problems can result from a failed heater, relay, circulation pump, pressure or flow switch, wiring connection, control board, low water flow, clogged filter, or another spa component.

Diagnose the complete system before replacing parts.

Rigorously Tested for Dependable Performance

Wholesale Sensors replacement temperature sensors are designed for dependable operation in demanding pool and spa environments.

Each replacement for Balboa 30352 is rigorously tested for temperature-sensing response, electrical continuity, connector integrity, wiring quality, and consistent functional performance.

The 96-inch cable provides the required reach for compatible installations, while the 3/8-inch sensor bulb is designed to fit the appropriate temperature sensing location.

Reliable sensor performance helps the spa control system receive the temperature information required for consistent water temperature management.

Straightforward Replacement Installation

Before servicing a spa or hot tub, disconnect electrical power at the breaker and follow the equipment manufacturer’s recommended safety procedures.

Locate the existing temperature sensor and note its mounting location, cable routing, and electrical connection before removal.

Install the replacement 3/8-inch bulb in the same intended sensing location as the original sensor. Route the 96-inch cable along the original path where possible and protect it from sharp edges, excessive heat, moving equipment, and areas where it could become pinched.

Connect the 2-pin plug securely to the appropriate control-board connection.

After installation, restore power and verify that the spa displays a reasonable water temperature and operates normally.

If temperature or heating problems remain, inspect the wiring, heater, circulation system, safety circuits, and electronic control system before replacing additional components.

No Automotive OBD-II Codes

The Balboa 30352 is a hot tub and spa temperature sensor, so automotive OBD-II diagnostic codes do not apply.

Balboa spa controls may display system-specific diagnostic messages when abnormal temperature or sensor conditions are detected. The exact diagnostic behavior depends on the control system.

For that reason, this replacement does not claim to universally resolve a specific spa error code. Troubleshoot displayed errors according to the service documentation for the exact Balboa control system.
