If you notice a red high-pressure switch (HPS) light on your condo heat pump’s circuit board, it typically signals an issue related to elevated refrigerant pressure. The HPS serves as a safety mechanism, designed to deactivate the heat pump compressor when refrigerant pressure becomes excessively high. This illuminated light indicates a potential problem requiring expert attention.
Understanding the Significance of a Red High-Pressure Switch (HPS) Light
In the context of condo heat pumps, it is imperative to recognize the critical role played by low-pressure and high-pressure sensors. These sensors are strategically incorporated to safeguard the compressor, preventing damage in scenarios where pressures exceed the designated threshold. Failure of these pressure sensors at critical moments poses the risk of damaging the heat pump compressor and may even lead to potential flooding within your condo.

Here Are Six (6) Possible Reasons for a Blinking HPS Light on Your Condo Heat Pump Circuit Board
- Refrigerant Restriction/Overcharge: Your system has a possible restriction within the refrigeration components. To resolve this problem, a mechanic needs to identify the restriction * to replace the faulty component.
- Heat Pump Overcharged: Another possible reason is that your heat pump chassis is overcharged. If you had previous technicians adding refrigerant to your system, there may be a possibility to have an overcharged heat pump.  Excessive R410A or R22 Refrigerant in the compressor can lead to an increase in pressure across the refrigerant circuit, triggering the HPS to shut down the system. Replacing the compressor may be necessary to resolve this issue.
- Restricted Air Flow: A dirty or thick air filter on the heat pump can impede airflow, causing an increase in refrigerant pressure. This can activate the HPS. Ensure the front access panel is unobstructed by furniture or sofas.
- Lack of Airflow: If your existing blower motor is currently weak, there is a possibility that your system is overheating due to lack of sufficient air needed to operate the system. If this is the case, a certified technician has to replace the existing motor in the heat pump cabinet.
- Faulty High-Pressure Switch (HPS): Sometimes, the High-Pressure Sensor (HPS) itself may malfunction or be improperly wired or faulty, causing it to activate even when the pressure is normal.
- Building Water Pressure: Water Source Heat Pumps rely on building water pressure and temperature. Deviations from standard heat pump requirements may lead to sudden shutdowns and a red HPS light. This normally occurs in the hotter summer months when the building water supply is too warm for the system. Consult a qualified Condo HVAC Specialist and obtain a formal report before informing your property manager.
Taking Action on a Blinking HPS Light
If you observe the red HPS light on your condo heat pump circuit board, it’s crucial to contact a Condo HVAC service company promptly. A technician will diagnose the issue and recommend necessary repairs to restore safe and efficient system operation.
