Heat pump is cycling (on / off too quickly) Bad valve or improper water flow Low refrigerant, low ambient temp, or high humidity with low ambient temp Check valve settings and ensure water flow is sufficient (is the filter pump running continually?) If heat pump continues to cycle, turn unit off to prevent compressor damage. Check evaporator coil for severe frost. Turn unit off to prevent compressor damage.
