Unbranded Hot Tub Accessories 73992 sku-18021660187
No rating yet(0 ratings)This Unbranded Black high-limit thermistor directly replaces Watkins part 73992. It fits Watkins Solana spas from 2006 forward and Hot Spot spas from 2006 to current models, excluding Grande and Vista. The sensor shuts off spa power if water leaving the heater exceeds safe temperature limits, helping prevent overheating and damage.
A faulty thermistor can cause shutdowns that require a power cycle; replacing it can restore operation. Its black plastic tip helps identify the part and check fit. Built for exposure to spa water and chemicals, it monitors temperature. Listed as Hot Tub Accessories; SKU sku-18021660187.
