Recalibrate Your Oven Temperature Setting
If the temperature in your oven seems off, or if your new oven just doesn't heat like your old one, you can recalibrate the temperature setting. Use the instructions in your manual or go online and search for a downloadable version using your oven's model number. Place a good-quality oven thermometer on the center shelf and wait for the oven to maintain a constant temperature. Then follow the procedure outlined in your manual to match the temperature setting to the thermometer reading.
Keep It Quiet
Keep the Dishwasher Clean
When your dishwasher no longer gets your dishes clean, a food-filled filter is most often to blame. If it's clogged, water can't make it to the spray arms to clean the dishes in the top rack. The fix takes two minutes. Simply pull out the lower rack and remove the filter cover inside the dishwasher. (Check your owner's manual if you can't spot the filter.) Then use a wet/dry vacuum to clean off the screen. While you're there, slide the nearby float switch up and down. If the cover sticks, jiggle it up and down and clean it with water.
