Defrost Cycle Explained
In our previous section, we discussed the importance of heat pumps defrost cycles. We'll provide a brief overview of the process:
- The reversing valve is energized, switching the system into air conditioning mode.
- The outdoor evaporator becomes the condenser, and the outdoor fan shuts off.
- The high-pressure refrigerant circulating through the outdoor coil gets warm, melting the ice.
- The second-stage heat (back-up heat) is energized to offset the cold air blowing out the vents.
- When a sensor or thermostat reaches a certain temperature or time threshold, the system returns to normal heating mode.
Troubleshooting Common Issues
We've identified common causes of heat pump malfunction, including:
- Bad defrost control or timer (professional fix)
- Bad defrost thermostat or sensor (professional fix)
- Bad defrost relay (professional fix)
- Sticking reversing valve (professional fix)
- Low refrigerant charge (professional fix)
- Outdoor coil blocked (professional fix)
- Unit sank in the ground (professional fix)
- Leaking gutter dripping water (homeowner fix)
