A red low-pressure switch (LPS) light on a condo heat pump circuit board or control panel typically indicates that the system is experiencing low refrigerant pressure. The LPS is a safety pressure switch that is 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 5 possible reasons why the low-pressure switch (LPS) light on your heat pump may start blinking red including:
1. Refrigerant Leak
If the heat pump is low on refrigerant, the LPS, the LPS may act to prevent the system from operating without enough refrigerant to transfer heat effectively.
2. Compressor Malfunction:
If the compressor works inefficiently due to mechanical issues then 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 o activate even when the pressure switch is normal.
5. Building Water Pressure
Water Source Heat Pumps rely heavily on building water pressure & temperature to operate properly. If the building water pressure or temperature does not follow standard heat pump requirements then 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 in order to inform your property manager.
Is there a red light blinking 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.
Schedule an Inspection
Condo heat pump systems are not part of common heating & cooling elements in high-rise buildings. This means that it’s the individual owner’s responsibility to arrange an emergency repair or maintenance service call in case of a mechanical failure or sudden breakdown. If you’re experiencing a problem with your condo heat pump, air conditioning, or heating system, then you’ve come to the right place.
We have a designated technical support & test center for troubleshooting all types of vertical and horizontal heat pump systems in condominiums & commercial high-rise buildings.
