Answer 1

Answer:

Explanation:

There is a do it yourself solution to see if your refrigerator is leaking Freon. You can mix ordinary dish soap with a little bit of water and spread it, or put it in a spray bottle and spray it on the tubing. As the gas escapes the leak, it will now go through a thin layer of soap, creating tiny bubbles to form.
