Pool heater parts keep gas and electric pool and spa heaters operating inside safe temperature and flow limits. When a high-limit thermostat opens, a flow switch fails to prove circulation, or a thermistor drifts out of range, the heater may lock out, short-cycle, or refuse to fire. Replacing the correct control—not guessing by heater brand alone—gets the system back online.
This collection on qs-ys.com groups aftermarket pool heater parts and related pool/spa controls sold by DELEYAPARS: high-limit / limit switch style thermostats, flow switches, temperature sensors and thermistors, and other compatible heater-side components as listed. Product titles include OEM-style numbers used for matching—for example 009577F, FDXLTER1930, GLX-PC-12-KIT, 7784/7790, 471694, 42002-0025S, 6560-860, and related codes shown on each product page. Those references describe compatible replacements, not authorized OEM service parts.
How US buyers typically order:
- Find the OEM part number on the failed switch, sensor, or in the heater parts diagram.
- Confirm connector type, probe length, and temperature rating against photos.
- Do not interchange engine coolant sensors with pool/spa thermistors—different systems, different part numbers.
