What to do if my Swegon Heat Pump compressor is not operating?

  If the compressor is not operating, there are several potential causes. First, check the operating or safety switch, as the voltage may have been isolated. Second, verify and correct the phase sequence if it's incorrect. Third, check the condition of the fuses, as the compressor safety circuit may have been broken. Finally, if none of these resolve the issue, the compressor may be defective and require replacement.

Why is my Swegon Heat Pump capacity too low?

  Tara NicholsAug 10, 2025
  Several factors could cause a reduction in your heat pump's capacity. Begin by checking the operating or safety switch to ensure the voltage hasn't been isolated. Also, inspect the evaporator for proper airflow. If airflow is insufficient, address the blockage. Additionally, check for refrigerant leaks and replenish if necessary. Finally, examine the thermostat or control equipment settings and replace any faulty components.

What to do if my Swegon Heat Pump compressor switches off due to low pressure?
- T
  Travis KellyAug 16, 2025
  If the compressor shuts down because of low pressure, possible causes include: insufficient refrigerant (indicating a leak in the cooling system, which should be tightened and recharged), inadequate airflow across the evaporator (so check the airflow). It could also be a defective expansion valve or a faulty low pressure switch, both of which should be checked and replaced if necessary.

What to do if my Swegon Heat Pump compressor shuts off due to high pressure?

  If the compressor is switching off due to excessively high pressure, it could be due to several reasons. Start by checking the airflow across the condenser. Also, check the exhaust air temperature. Finally, the high pressure sensor itself might be defective and require replacement.

Why is there significant freezing on the evaporator of my Swegon Heat Pump?
- F
  Frank RobinsonAug 27, 2025
  If there's significant freezing on the evaporator, it could be due to a defective or incorrectly set expansion valve, so you should check it. Another possible cause is insufficient airflow across the evaporator, so check the airflow.
