Pool Pump Thermal Overload Switch

Tristar vs 950 omni.

Pool pump thermal overload switch. While manual reset thermal overload switches are most common on heating systems such as oil burners and some fan motors air conditioner electric motors and compressor motors and submersible well pump motors are an example of motor designs that may be use a thermal overload switch that resets itself automatically when the motor has overheated. This is the second part of a two part series on pool pumps. As we discussed last time heat is the main reason pool pumps will fail. We also have an electric heat pump heater as well as a solar attic solar system in the loop.

To read the first entry click here. Tristar single speed pump 0 75 hp max rate. For safety reasons many pool pumps are designed to shut off automatically if they begin to overheat. Electric motor thermal overload switch location.

The mechanisms that perform this task are known as thermal overload switches. By far the largest cause of your pool pump being too hot is a degenerative process where heat and age cause the pump to draw too much current. To understand why you first need to understand how an electric motor works along with some basic electrical theory. The unit is 3 years old and runs year round in that we have water features with our pool.

Carefully re secure the capacitor and thermal overload switch. Use the wrench to wiggle the shaft through several revolutions to break any rust that has formed between the stator and rotor and free up the shaft. First a pool pump motor is made up of copper windings. If the motor does not turn on check the breaker and timeclock switches.

Tristar 1 5 hp pool pump full rate single speed item sp3215ee. Electric motor thermal overload switch location. A pump that is too large for your pool will force a large amount of water through a filter that is too small resulting in strain and resistance that will cause the pump motor to wear down and die prematurely. If your pump continues to shut off it could mean that the thermal overload switches are going bad.

Locate a dealer. It is always a good idea to operate the pump at the lowest flow rate needed to circulate your pool s water in 8 hours. Locate a dealer. I have a jandy 1 1 2 hp single speed pump.

We have had no issues with the system until recently. Locate thermal overload protector this picture shows the location of the thermal overload protector within the electrical components of the motor. Locate a dealer. Even a closed valve that should be open can be enough to cause a pool pump to catch on fire although this is a rare problem in comparison to electrical failures in pool pumps.

Step 3 discharge capacitor pool pump capacitors store an electrical charge that can shock you even when the power is off.
