Below the balance point, around 30 ° F it is normal for the outdoor fan to continually run. If the outdoor unit continually runs during normal heating (30 °-50 ° F outside), possible problems are:
- Thermostat set too high
- Thermostat needs adjustment
- Low refrigerant level in unit
- Thermostat exposed to cold draft
- Outside unit coil is blocked by snow, ice, etc.
If the outdoor unit continually runs during normal cooling, possible problems are:
- Low refrigerant level in unit
- Very warm weather (over 90 ° F)
- Thermostat located near heat source, such as appliances, TV, etc.
- Dirty filters or too many registers closed limiting air movement
- Improperly designed duct work
- Unit may be undersized
