DIY Home Maintenance Tip - Refrigerator
Inspect Refrigerator Seals
Try closing the door on a dollar bill or a piece of paper. If you can pull the paper out without tearing it, the seals need to be replaced. You also need to dust or vacuum the coils behind the refrigerator to ensure that the coolant is flowing properly.
Clean Coils In Your Refrigerator:
Depending on your model, the coils are either behind the kickplate or at the rear of the fridge.
Use a shop or handheld vacuum to suck up any loose particles.
Vacuum every 6-12 months.
