The working parts of refrigerators should be cleaned every year. Dial-A-Maid Cleaning Service in Evanston, Il. 60201, recommends. Always unplug the Fridge before you attempt to clean it. Refrigerators work by removing heat from inside the refrigerator, then the condenser coils release the heat into the room. Your sleepy pet absorbing the heat blowing from under the refrigerator, is making the Fridge work harder and get dirtier faster. Try to discourage your pet from lying there. Pet hair should be vacuumed out from under and behind your refrigerator two or three times a year.
Older refrigerators need to be pulled away from the wall so the condenser coils at the back can be carefully and gently vacuumed. If dust is allowed to build up on the coils the compressor can give out, which is the refrigerator equivalent of blowing the engine. Older refrigerators have been known to catch fire, so it's a good idea to have your aging appliance checked annually by a technician.
The coils of newer refrigerators are usually sealed, but you should pull your newer refrigerator away from the wall and vacuum under it at least once a year anyway. Or, if you can't move the Fridge, slide a small washable cotton rug under the refrigerator and move it from side to side to capture and remove dust bunnies.
Dial-A-Maid cleaning Service in Evanston, Il. 60201, strongly suggests following the above practices to ensure the longevitiy and functionality of your Fridge for years to come.
