Omega Heat Pump Flashing LPS Red Light. What Does It Mean?

A flashing LPS Red Light could be indication of Low-Pressure Switch (LPS) on a OMEGA Heat Pump Circuit Board or control panel. The Blinking Red light typically indicates that the system is experiencing low refrigerant pressure. The LPS is a safety pressure switch designed to shut off the heat pump if the refrigerant pressure in the system becomes too low. When the light is illuminated, it typically means that there is a problem with the system that needs to be addressed. If you are experiencing issues with your heat pump and the LPS light is illuminated, you should contact a qualified Condo HVAC Company to diagnose and repair the problem. We provide professional Condo Heat Pump Repair Services for all OMEGA, Whalen, Johnson Control & ClimateMaster systems.

Do you constantly need to reset your condo heat pump from the breaker panel?

Here are 6 possible reasons why the low-pressure switch (LPS) light on your heat pump may start blinking red:

      1. Refrigerant Leak

If the heat pump is low on refrigerant, the LPS sensor will get activated to prevent the system from operating on low pressure. This function will also protect the compressor from being seized due to starving refrigerant.

      2. Compressor Malfunction:

If the compressor works inefficiently due to mechanical issues, there is a drop in pressure across the refrigerant circuit. As a result, it can trigger LPS to shut down the system. In this case, you need to replace your chassis compressor to resolve this issue.

      3. Restricted Air Flow

If the air filter on the heat pump is currently too dirty or too thick, it can restrict the airflow and cause the system refrigerant pressure to drop. As a result, LPS gets activated. Please also keep that in mind, no furniture or sofa should block the front access panel.

     4. Faulty Low-Pressure Switch (LPS)

In some cases, the LPS itself may be malfunctioning or improperly wired causing it to activate even when the pressures are normal.

     5. Defective Control Board

Heat pump Chassis is require a steady supply of electricity to operate correctly. If there is a problem with the electrical compartment of your heat pump, it could cause the red light to flash. It is due to a faulty circuit breaker which sends the wrong signal to the chassis.

     6. Low Building Water Pressure/Temperature

Water Source Heat Pumps rely heavily on building water pressure & temperature to operate appropriately. If the building water pressure or temperature does not follow standard heat pump requirements, you may experience sudden shutdowns & red LPS flashing on the control boards. Before addressing this problem with your condo management, you need to have a qualified condo HVAC specialist provide you with a formal report to inform your property manager.

Is there a red light flashing on your heat pump circuit board?

The technician will be able to diagnose the issue and recommend any necessary repairs to get the system running safely and efficiently again.
