The garbage disposal is jammed, the gas burner's cooked, and you're afraid to give the dishwasher a ?look?. What can you do when Friday the 13th appliances plague you? Here are some simple fixes for problems like this. For the disposal, make sure the power is off, then open the cabinet and look on the bottom of the disposal housing. You'll see a hole for a hex wrench that you can use to manually un-jam the blades. For the stove, the problem may be clogged burners from dropped food and grease. Clear them with a toothpick and they'll burn free. Regarding the dishwasher, if it's okay for the moment, run it weekly to keep seals and gaskets moist and put a teaspoon of mineral oil in the bottom on the days in between. Then, with your kitchen once again ?humming? along, you can relax... and start singing a happy song!
