Heat Pump Defrost Too Frequent – Melting More Than Ice

Heat pumps use defrost cycles to keep the outdoor coil clear, but too many cycles waste energy and reduce comfort.
Chatterbox detects abnormal defrost behavior by analyzing coil temperature, outdoor humidity, and compressor activity. When defrost happens too often, it means the sensor or board is misreading conditions.
After replacing the sensor, the system resumed proper operation—less downtime, more heat, and lower bills.
