Cleaning Refrigerator Coils

October 4, 2021 by james

When the pandemic began and some of us were stuck at home, I made a short video about cleaning your refrigerator coils. This is a simple process and something that should be done at least once a year, if not twice a year. When your refrigerator is running, the fans pull air through the lower grille. This helps exhaust the heat being pulled from within the refrigerator and freezer. But, behind that grille may be dirty coils. If not cleaned periodically, your refrigerator will not be able to cool properly. If not cleaned periodically, the trapped hair, dust, and lint will insulate the coils, trapping the heat, and restricting air flow.

📌 You can extend the life of your refrigerator by cleaning the coils once or twice a year.

These coils can be difficult to clean. They don’t have sparkle and shine when you’re done. The main objective is to use a narrow Coil Cleaning Brush to slip through the openings and help knock down some of the built-up dust. Get as much as you can. Don’t use anything that might puncture the coil or damage the refrigerator.

How To Test Continuity

How To Test Continuity

Definition of a Continuity Test

“In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit).”

Thank you Wikipedia.

How To Test Continuity | Basics and Examples

Which parts can I test for continuity?

“A continuity test can be used to test switches, fuses, electrical connections, conductors and other components. A good fuse, for example, should have continuity.”
Thank you Wikipedia and Fluke.

In the video above, we demonstrate tests on:

  • Electric Range Surface Element
  • Incandescent Light Bulb, CFL
  • Cherry switch
    • Normally-Closed, NC
    • Normally-Open, NO
    • Common, COM
    • Often used as a belt switch, lid switch, or door switch
  • Power Cord

How do you test continuity?

Parts are often tested by themselves, disconnected from the appliance, with a meter connected to the leads or connection on the part, testing continuity from Point A to Point B.

If the part has continuity, is it “good? If it doesn’t, is the part “bad”?

No. Below is a supplemental video showing the difference. Fuses may look like thermostats, and thermostats may look like fuses, and parts may be “normally open” or “normally closed” depending on their purpose inside the appliance.
