Living out a tiny farm in the middle of nowhere as I do, there are plenty of things you have to learn to maintenance on your own for lack of being able to call in a professional to take care of various repairs. I was essentially raised on this farm plus l acquired how to take care of every part of it from my parents. Both were rather smart plus industrious people who could turn a cable television into a wristwatch if they had the desire to do so. They taught me electrical work, plumbing, general carpentry, mechanical repair, plus Heating & A/C appliances. Now that this farm is in the middle of its second plus third generation I am playing the role of my parents with children of my own who are studying how everything operates. Just the other day I had to show my child how to replace a broken ignition switch on the gas furnace. Somehow the switch had become fused plus would not light the gas coming out of the burners anymore. I honestly had never seen an ignition switch do that before plus we had to drive into town to find the correct upgradement part. The store in town is operated by a Heating & A/C worker plus he had never observed anything like that fused ignition switch either. Commonly, they will crack or warp, but this one in particular was bent back onto itself plus fused. Maybe little Heating & A/C aliens got into our gas furnace in the middle of the night plus made that happen. In any event, teaching my child how to maintenance these things is truly fulfilling to me.
