What Does Error P7 Mean?
The TECO Air Conditioner error P7 signals an overheating issue in the outdoor unit's discharge temperature, indicating a malfunction in the temperature sensor. This error can lead to erratic cooling performance, with symptoms including the outdoor unit ceasing operation, reduced cooling, and excessive heat in the exhaust area. Proper airflow obstruction or a faulty temperature sensor may be the underlying causes.
Common Symptoms:
- Outdoor unit stops operation with P7 displayed
- Cooling performance reduced or fan running but compressor not engaging
- Exhaust area of outdoor unit feels very hot
Possible Causes
- Outdoor discharge temperature overheating (insufficient condenser cooling) (medium)
- Faulty exhaust temperature sensor or sensor reading error (medium)
How to Fix Error P7
