About This Item
The Hayward Temperature Limiters Kit (HAXTLK1930) is the OEM replacement temperature limiter assembly for Hayward pool and spa heaters. Temperature limiters are safety-critical thermal cutoff components that interrupt heater operation when internal temperatures exceed safe thresholds, protecting the heater from heat-exchanger damage and unsafe operating conditions.
IMPORTANT: PROFESSIONAL SERVICE REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
IMPORTANT: VERIFY COMPATIBILITY BEFORE ORDERING
No compatibility data is currently available for this part. Verify the part number against your heater's parts diagram or installation manual before ordering to confirm fitment with your specific model.
What It Does
The temperature limiters in this kit serve as thermal safety devices within the heater assembly. When heater internal temperatures reach the limiter's rated threshold, the device interrupts the heating circuit to prevent damage and unsafe operation. Replacing worn or tripped temperature limiters restores the heater's ability to monitor and respond to thermal conditions correctly.

Poolaroo Pro Tip
A temperature limiter that trips repeatedly is often a symptom of a root cause — restricted water flow, a failing pressure switch, or scale buildup on the heat exchanger. Before replacing the limiter kit, confirm that water flow through the heater meets the manufacturer's minimum flow rate requirement. Replacing the limiters without addressing the underlying cause will result in repeat failures. Consult your heater's installation manual for minimum flow specifications and have a licensed pool professional inspect the system if thermal shutdowns recur.
