Which outcome occurs when a heat pump's reversing valve fails in cold weather?

💡 Explanation

When a heat pump's reversing valve fails, redirection of refrigerant flow doesn't occur because the valve is stuck, preventing heat transfer to the indoor coil. Therefore, only cooled air is delivered indoors, rather than heating, winding failure, or frozen coil which require normal heat transfer.
