![M-CLASS-MP High Limit Band — Genuine Gecko Replacement Part
Is your Gecko M-CLASS or M-SPA-MP hot tub shutting down unexpectedly or running too hot? The M-CLASS-MP High Limit Band is the OEM-grade temperature safety sensor your spa needs to run safely and reliably. This is a genuinely hard-to-find part — and Western Tub and Pool has it in stock.

What Is the M-CLASS-MP High Limit Band?
The M-CLASS-MP High Limit Band (also known as the Hi-Limit Temp Sensor Assembly) is a critical safety component in Gecko M-CLASS and M-SPA-MP spa control systems. It continuously monitors your hot tub's water temperature and automatically shuts the heater down if the water exceeds a safe threshold — protecting both your spa equipment and you.
Without a functioning high limit sensor, your spa may:
Fail to heat properly or shut off unexpectedly
Display error codes (such as OH, OHH, or HL fault codes)
Overheat, causing damage to internal components
Become unsafe to use
Replacing a faulty high limit band is one of the most cost-effective repairs you can make to restore your hot tub to full working order.

Frequently Asked Questions
How do I know if I need a new high limit band?
Common signs include your spa displaying an OH, OHH, or HL error code, the heater shutting off randomly, or the water temperature becoming unregulated. If your spa is cutting out due to overheating or failing to maintain temperature, the high limit sensor is often the culprit.
Is this part compatible with my hot tub?
This band is specifically designed for hot tubs running a Gecko M-SPA-MP or M-CLASS control system. To confirm compatibility, locate the label on your spa's control box or check your existing sensor's part number. If you're unsure, contact us — we'll help you figure it out.
Is this a new part?
Yes. All M-CLASS-MP High Limit Bands sold by Western Tub and Pool are brand new.
What information should I have ready when I contact you?
To help us confirm the right part for your spa, please have the following on hand:
Your spa's make and model
Your spa's serial number
The part number from your existing sensor (if visible)
Photos of the existing sensor and control box label are also very helpful
Can I install this part myself?
Many spa owners are able to replace the high limit band themselves, as it is a relatively straightforward swap. That said, if you're not comfortable working with spa electrical components, we recommend consulting a licensed spa technician.
How do I order or get more information?
You can shop directly through our online catalogue, call us at 1-855-248-0777, or email fixmytub@gmail.com. We're here to make the process as simple as possible.

Is your Gecko M-CLASS or M-SPA-MP hot tub shutting down unexpectedly or running too hot? The M-CLASS-MP High Limit Band is the OEM-grade temperature safety sensor your spa needs to run safely and reliably. This is a genuinely hard-to-find part — and Western Tub and Pool has it in stock.

What Is the M-CLASS-MP High Limit Band?
The M-CLASS-MP High Limit Band (also known as the Hi-Limit Temp Sensor Assembly) is a critical safety component in Gecko M-CLASS and M-SPA-MP spa control systems. It continuously monitors your hot tub's water temperature and automatically shuts the heater down if the water exceeds a safe threshold — protecting both your spa equipment and you.
Without a functioning high limit sensor, your spa may:
Fail to heat properly or shut off unexpectedly
Display error codes (such as OH, OHH, or HL fault codes)
Overheat, causing damage to internal components
Become unsafe to use
Replacing a faulty high limit band is one of the most cost-effective repairs you can make to restore your hot tub to full working order.
