The 34-0202B-K M7 Temperature Sensor is a replacement spa/heater probe designed to accurately measure water temperature in spa and hot tub systems. It sends precise temperature data to the control board, enabling reliable temperature regulation, safe heater operation, and accurate display readouts.

Specifications:

• Accurate temperature monitoring provides precise water temperature feedback to the spa control system for safe, efficient heating
• Built-in M7 connector for straightforward plug-and-play connection to compatible spa controls
• 46" (approx. 117 cm) cable provides flexible routing inside the spa pack and easy reach to the probe mounting location
• Durable construction withstands high humidity, heat, and exposure to spa water and chemicals
• Critical safety component — works with spa control boards and heaters to prevent overheating by enabling proper temperature regulation and sensor monitoring circuits
• Compatible with many spa and hot tub systems using the M7 temp sensor format; always verify connector type and cable length before ordering
• Part no. 34-0202B-K

Returns & installation: Confirm your spa control board uses the M7 connector format and that the 46" cable length reaches your probe mounting location before ordering, as electronic parts are non-returnable once installed. Installation should be performed with power disconnected, per your spa's service manual.

FAQ

Q: How do I know if this sensor needs replacing?
A: Inaccurate temperature readings, error codes, or a spa that won't reach or hold set temperature are common signs of a failing sensor.

Q: Will this fit any spa system?
A: Confirm your spa's control board uses the M7 connector and requires a 46" cable before ordering.
