Pool Chlorinator Repair Kit- AQ (For GLX-PCB-RITE ) Includes SL32 2R025 Thermistor. (Also can replace AS32 2R025) High-Energy Thermistor and 2 V150LA2P Varistors. Replacement parts for the Chlorinator PC Board after parts fail due to a large power surge. This board failure is often due to the "sacrificial" destruction of the Thermistor, a Varistor, or the Fuse used to protect the circuit from high voltage and high current surges that could occur after a lightning strike during thunderstorms or other power surges. Normally the thermistor protects the circuit on start-up, providing a relatively high resistance (2 Ohm) at ambient temperature to limit "InRush Current", and then essentially disappearing from the circuit (0.02 ohm) when the current is near or equal the design current of 25 Amp. The part will fail when a power surge is much greater than the power handling capability of the part. The correct replacement thermistor is: ICL - SL32 2R025 High Energy Dissipation without Failure Inrush Current Limiting (ICL) Thermistor (1 Thermistor) (Inrush Current Limiting Thermistors) (Use to repair: PCB (GLX-PCB-RITE) Pool Chlorinator) ICLs (Inrush Current Limiters) are a cost-effective way of limiting the inrush of current that can damage other components in a switching power supply and other devices when the equipment is turned on.
