Question about Smith AO Pool Pump Motor

1 Answer

Overheats and trips off

Pump overheats and trips off internally - breakers do not trip. Pump cools and restarts and runs for 5 minutes then trips off again.

    The motor is around 15 years old. The impeller was broken (seperated) when I opened the pool up this year and I replaced it with a similar one, but one that would work by Pool Care rep.



    It has good flow of water when it is running - it pushes water thru a chlorinator with tablets - it has 5 - 2" tablets in it - I'll remove some and try this evening.

Internal thermal over loads in motor are working properly! how old is the motor? double check all vavles on the intake and discharge line to make sure that they are open? sounds like the pump is pushing against what is known as dead head pressure. obstruction in discharge line! if valves are ok you can take the jet covers off (the piece that helps direct flow of water) which will relieve some of the pressure should allow it to run without tripping tgermal overloads. if none of this works replace motor!!

Duo Therm A/C (2009 Sabre RV) won't shut off


bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.

Oscillating drum sander runs a few minutes and stops


This usually occurs if the motor is overheating and the internal circuit breaker is tripping. After it cools down, it self resets. This can be caused by bad bearings or parts dragging the motor down, making it work hard enough to over heat and trip the breaker. If you are running it on an extension cord or circuit that isn't able to provide it with the amps it needs the motor will overheat and trip the breaker also.

It is probably only getting 115V from your circuit which will cause it to overheat and trip the overload yet it will not draw high current which would trip the breaker. Can you confirm your line voltage with a meter? If it is suppoed to be a 230V line then look for a bad leg of power, again, checking each leg to ground using a meter.

Unit comes on and runs for 5 minutes, the circuit trips off


30 is the correct size breaker for this unit. It sounds like there is a grounding issue going on in the system. Or off of the Thermostat. Something is grounding out causing the switch to trip. Are you running #10 wire to breaker and the unit? If not you will need to increase your wire size

Unit shuts off on hot days


It may be low on refrigerant. On hotter days, the compressor has to run longer to reach the temperature you have on your thermostat. Have it checked for the proper refrigerant charge and have them test how many amps that the compressor is pulluig as well. With the proper breaker installed, the unit should not be tripping out. Make sure that the breaker that is in there now is actually the proper one for your unit.
