Balboa Temperature Sensor with 12 inch cable PN 30344

BALBOA STANDARD TEMPERATURE SENSOR WITH 12 INCH CABLE PN 30344

PN 30344 consists of the standard thermistor temperature sensor used in the M7 series of Spa packs, including the VS, GS, EL, and GL models. The lead length is 12 inches. Each spa pack utilizes two sensors. If the sensors become unmatched and display an Sn error message, one or both must be replaced to restore functionality.

The Solution for "Sn", "SnS", and "Sensor Sync" Errors

If your topside panel is flashing an "Sn" or "SnS" error code, your spa isn't broken—your sensors are just out of sync.

The Balboa 30344 is the genuine OEM replacement temperature sensor for Balboa's M7 Control Systems.1 These intelligent sensors perform double duty, monitoring both Water Temperature and Water Flow (High Limit) simultaneously, eliminating the need for old-fashioned pressure switches.

Pro Tip: Always Replace in Pairs

Your heater tube uses two of these sensors (Sensor A and Sensor B). The computer constantly compares their readings to ensure safety.

• Why buy two? If one sensor fails or drifts, the system sees a mismatch and shuts down. Replacing only one often leads to the same error returning a week later because the new sensor is accurate, but the old one has drifted.

• Recommendation: Save time and shipping costs by replacing both sensors at the same time to ensure a perfectly balanced system.

Compatibility Check

This sensor fits directly into the heater housing of virtually all Balboa M7 systems, including:

• Series: VS, GS, EL, GL, and BP Series.

• Heater Models: Fits 4.0kW and 5.5kW heater tubes.

Important: Check Your Cable Length

This model (PN 30344) features a 12-Inch (30cm) Cable.

• Please measure your old wire. If your control board is mounted far away from the heater, or if you have a "remote heater" setup, you may need the 24-Inch version (PN 32016) instead.
