周末省钱不容易：沃尔普冰厢Defrost手控操作程序

7年的沃尔普冰厢突然冷厢不冷了，但冻厢还工作。记忆中似乎久远的以前碰到过类似问题，很简单的操作就修好了。但是具体是咋搞定的回忆不出来了。于是上油管上查询。一大堆专业修理师的15分以上的高质视频，很复杂的拆着换那儿，一看就象把事情复杂化吓唬你找专业修理师骗钱的。但见到一个用户的 1分半的手机晃动视频，声音也不太好，就嘟哝了几句浑浊洋文：it's time to defrost，dude. had to turn off power overnigh。就是它！要defrost。查看了一下冻厢发现气孔是有些冰霜结，可能是需要手动defrost通通气，这样冷气才能顺畅吹进冷厢里。

于是就把冻厢清空，关了电源。一小时左右后就开始看到冰霜水融化嘀嗒流下了。又等了一个小时，更多的冰霜水融化嘀嗒流下。但冻厢清空出来的食物也都融化了。感觉好象有点不对劲儿。这么多水会流出来到地上的！马上又查官网的维护网页查找手动defrost正确方法。没有。再谷歌搜寻，看到一帖提到手动defrost，仔细阅读，总算在字里行间找到了操作程序：犹如登月飞行自动降落失灵，宇航员启动手控操作；但比新一代波音737MAX自动提头失灵飞行员启动手控操作复杂。难怪官网的维护网页查不到。有个专业修理师在他视频里快速的浑浊地嘟哝了提一句这个操作，但没引起太大注意，因为没有演示无法学。

The forced defrost mode is started out of the diagnostics mode. If you are in diagnostics you can exit by closing the refrigerator door. This is a nice one because you can do a forced defrost cycle as long as the refrigerator's defrost thermostat, heater, and control are okay.
It is fairly common to have a large amount of frost build up and block airflow into the fresh food area if the freezer door did not get closed all the way for a few hours. The signs of this happening are clear, large amounts of frost or "snow" all over the freezer compartment or frost build up near the front of the freezer compartment near the door gasket. Doing a "long" forced defrost will probably get things back to normal.
To run a forced defrost cycle open the refrigerator door or doors if your refrigerator is a french door model. Then hold down the door switch or switches, the display should go blank. Next press the refrigerator temperature (-) button 3 times in 10 seconds and release the door switches. The display should show "F" and "D" (Forced Defrost) press the refrigerator (-) button one more time to confirm that this is what you want to do. "S" for "short" should then be displayed in the refrigerator window. You can switch between long and short cycles with the refrigerator (+) button. To test the circuit the short option should be fine. However, if you are trying to get rid of a frost build up I would suggest the long cycle.
When you have made your selection press the refrigerator (-) button to start the defrost cycle. The display will go back to it's original settings and you can close the door. After a few moments if everything is working properly you should hear the sweet hissing sound of water dripping onto the red hot heater. If you don't hear anything in the freezer after a few minutes... "Huston we have a problem"

按照这个手控操作程序按来按去搞了一阵，终于进入正确defrost。再把食物放回冻厢。 但已经有些晚了，冰箱地下已经流出一些融水了。只好跪蹲在地上用旧棉布衣裤擦干。一边擦，一边心理大骂。。。 ：）
