Refrigerators And Freezers
Most refrigerators have more than one light. Replacement is easiest when at least one bulb is still working. When you first notice a burnt-out bulb, count the total number of bulbs in your unit. Unscrew any burnt-out bulbs and take them with you to the hardware store to make sure you buy the same type.
Buy enough for the whole refrigerator so you have spares as the other bulbs wear out. Whenever frost gets to be 1/4-inch thick, it’s time to defrost. Never use ice picks or similar tools to loosen ice. Some refrigerator shelves contain cooling fluids. These racks take longer to defrost. Don’t force the process, as the racks are easily damaged. Every year or two, vacuum underneath and behind the unit. After unplugging the unit, use a crevice tool or feather duster to help you clean the coil and all metal parts.
You may have to remove a panel to get access. This will make your unit last longer and run more efficiently. Keep the door seals and the surfaces they close against clean to reduce energy consumption and extend the life of the seal. If you close the door on a piece of paper and it slips out without resistance, it’s time to replace the door seal. Replacing the seal is more complicated than it looks, so if you’re not especially handy, it’s a job better left to the professionals.
