Pool owners with Raypak heaters, if your unit keeps shutting down or showing error codes, this 006725F high limit thermostat might be your fix. This auto-resetting switch is designed to cut power if the temperature hits 135°F, preventing damage to your heater - it's a crucial safety component. The compatibility is broad - works with Raypak models 185A/B, 206A, 207A, 265A/B, 266A, 267A, 335A/B, 336A, 337A, 405A/B, 406A, and 407A series. When these thermostats fail, your heater might not fire up at all, or it might run briefly then shut down. Replacement is pretty straightforward if you're comfortable with basic electrical work - just make sure to TURN OFF POWER at the breaker before you start! The auto-reset feature means it'll automatically restore power once things cool down, but if it's tripping frequently, you might have other issues like flow problems or a stuck pump. This is a direct replacement part that matches the original specifications, so the fit and function are exactly what your Raypak heater needs. Keeping your pool heater running safely is important, and this thermostat is a key part of that safety system. Whether you're a pool service pro or a handy homeowner, having the right replacement parts on hand can save you from expensive service calls. Just make sure this is actually the part you need by checking your heater's model number and symptoms - if your heater is tripping this safety regularly, you might want to investigate why it's overheating in the first place. But for a straightforward thermostat replacement, this is the right part at a reasonable price.
