SOURCE: we have aheat pump and

The LP is for low pressure of the refridgerant. Your pump coils are either frozen, or the switch pressure switch is bad, or you are just low on refridgerant.

Aqua pro 500 is flashing lp. We just had a new pump installed and are just trying to get pool warmed up. Pump worked fine last season. Any suggestions?thank you


LP: This code means "Low Pressure" or low pressure switch. Either the outside ambient temperature is below 50°F (38°F
for h/c units), which is too low for the heater to operate, or the unit is low on refrigerant. Once the outside temperature has risen above 60?F, and the LP code remains, call the factory for repair. https://ecoaquapro.com/wp-content/uploads/2014/06/AquaPro-Pool-Heat-Pump-Manual.pdf

My heat pump is displaying LP, what does this mean?


Low water pressure through the unit, you just need to adjust your valves to supply the right pressure to the heat pump.

I have a rome Industries Pool heat pump model 105 showing error code LP???? what does that code mean and what do I do?


I happen to work for Rome Industries and can help you out. The "LP" code on your control board represents "Low Pressure". This is referring to the refrigerant pressure within the unit. The unit is equipped with a low pressure safety switch that when activated shuts the unit down. This could be caused by a refrigeration leak, a stuck thermal expansion valve, or even a faulty pressure switch. If you live within the state of Florida contact Rome Industries and you will receive a free of charge service call including parts and labor as long as your unit is under warranty. If your outside of the state please contact your dealer to handle the claim. Have a good day.
