An important safety feature, the thermal overload switch cuts off the flow of electricity to the heating element when your appliance starts to overheat.
People also ask, how long do Hayward pool pumps last?
Your pool’s pump is the wet end of the operation, it houses the pump basket. Pumps should last through the initially installed motor and perhaps as many as two or three replacement motors, usually 10-12 years.
Consequently, how do you tell if a pool pump is burned out?
Signs You Need Pool Pump Replacement

What causes compressor thermal overload?
An overload might open due to: A lack of maintenance. If the outdoor coil gets dirty it can raise the head pressure and make the unit run hot. A defective run or start capacitor.
How do you bypass a thermal switch?
Locate and Bypass the Fuse
The thermal fuse will look like a thin strip of white plastic with a wire coming out of each end. In order to bypass the thermal fuse, use electrical tape to tape the two ends together. The thermal fuse will then be bypassed. Turn the dryer on to a heat cycle for no more than 90 seconds.
Do pool pumps have thermal overloads?
Overheating. For safety reasons, many pool pumps are designed to shut off automatically if they begin to overheat. The mechanisms that perform this task are known as thermal overload switches. If your pump continues to shut off, it could mean that the thermal overload switches are going bad.
What causes thermal overload trip?
Causes may include a large change in load (e.g., a scrap grinder is fed too much at a time), misalignment, a broken drive gear, or improper motor drive settings. Power problems (e.g., low voltage or low power factor) also may cause an overload condition.
How do you test thermal overload?
Overload Protection Test:
- Measure the normal motor running current (i motor).
- Turn off the motor and let it cool for about 10 minutes.
- Calculate the following ratio: i (motor) / i (overload min FLA). …
- Set the overload to its minimum FLA and turn on the motor.
- Wait for the overload to trip.
What will happen when we push the reset button on thermal overload relay?
When set in the H or HAND position the RESET button must be pressed manually to reset the overload relay after a tripping event. On the other hand, when set in A or AUTO position, the overload relay will reset automatically after a tripping event.
How do you reset a thermally protected motor?
Thermal protectors generally reset themselves once the motor cools down to a safe operating temperature. There is usually a visible red button located on the wiring side of the motor—usually, though not always, located opposite of the motor shaft.
What must be done before a motor overload can be reset?
the overload relay cannot be reset until the overload heater has cooled. The overload relay is reset by first turning the starter all the way off and then turning it back on. Overload relays will not trip due high over currents that last only a short amount of time.
