我希望有人能帮上忙。两周前我买了一个2.5吨的古德曼分体式热泵。几天前，温度降到了20度左右，设备一直在运行，从来没有达到恒温器上想要的温度。我检查了外面，里面和外面都冻得像块冰。显然，融霜周期没有正常工作。我给军人打了电话，他让我在他检查之前把它打开应急热源。第二天，太阳融化了装置上所有的冰，我又把它打开了。它工作完美，解冻正确，等等。军人检查了氟利昂水平，说他们没事。他说可能是控制板，但他不确定。 It works fine now, wouldn't it not work at all if the board was bad? He is stumped and so am I. I am worried that this will happen again when the temperature drops. What does anyone suggest? Please I need help here.
