Clone phone can have slight variations on the screen so yes an original part will not be compatible. You will have to find out what the knock off name is and try to order the part. Still do some code tests to verify that you actually do have a cloned phone. The techs could have been wrong.
Lets say it is Summer time and you want to set your ceiling fan to spin the correct direction. When looking at your fan from below, the fan should be turning counter clockwise, or forward. The reason for this forward spin direction is so you can get as much airflow as possible when it is hot outside.
Feel the breeze from your fans. If your home has ceiling fans, switch your ceiling fan to run counterclockwise in the summer. That will push the cool air down. You can run a ceiling fan half the day for about $1.50 a month, compared to $25 for an air conditioner.
