I was visiting with our Dad on Monday as well as the more than one of us were resting in the living room discussing some shows that the more than one of us saw on TV the previous afternoon. It was kind of sizzling outside as well as the undefined device in the living room was running. My Dad as well as dad do not have central undefined, because it's not absolutely necessary. They live on a hill where there is a constant breeze as well as they live in a climate where summertime hot as well as cold temperatures are never higher than 90 degrees. The living room undefined device was running simply because I was feeling warm. I started talking to our Dad about the TV show that I saw on the previous night as well as I heard the undefined device make a strain, hiccup sound. I told our Dad that the undefined device made a weird sound as well as she told me that everything was perfectly fine. I forgot about the hiccup sound until 15 minutes later when the undefined device started blowing sizzling air. I told our Dad that I knew I heard a sound, but she turned off the undefined device as well as told our dad to come upstairs. She was downstairs toiling on some concern in the basement. My dad grabbed her tools as well as took the front of the undefined device off. She started moving some things around as well as she found more than one electrical switches in the back of the machine. She crossed the wires as well as there was a small electrical spark. Two or 3 minutes later, the air started to get cooler. I don't think what our dad did to the machine, however it's certainly a fire hazard.
