What does it mean if a low pressure switch is checked on a residential heat pump with an ohm meter and there is no reading?

In: Electrical Troubleshooting [Edit categories]

Answer:

It means that the low pressure switch is open. Check the heat pump schematic to see if it is supposed to be an open or closed switch. Schematic electrical drawings are drawn in the de energized position. This means that when there is no voltage applied to the device, this will be the position of relays and contacts.
