Omega Heat Pump LPS Red Light or Low Pressure Sensor is an indication low refrigerant pressures in the heat pump chassis.  The LPS is a safety pressure switch that is designed to temporary cut off heat pump operation when refrigerant pressure is too low to run the heat pump. When the light is flashing, it typically means that there is a general 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.

Resetting Condo Heat Pumps May Not Be a Good Idea

Sometimes, the error may be caused by factors related to your building’s water temperature. Therefore, resetting the heat pump from the breaker panel or heat pump cabinet could potentially resolve the issue permanently. However, if you find that the system requires frequent resetting, it’s advisable to have a qualified HVAC technician inspect the problem to prevent damage to other components in the unit.

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 may act to prevent the system operating without inadequate 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

On heating mode, Dirty or restricted air filter 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?

If you are currently seeing the red LPS light on your condo heat pump circuit board, it is important to have the system checked by a Condo HVAC service company as soon as possible. The technician will be able to diagnose the issue and recommend any necessary repairs to get the system running safely and efficiently again.
