The first thing you should do if your refrigerator stops working is check that it has been plugged in. If there is no ice or water coming from the dispenser, then you have a problem with the water line, and it needs to be replaced. This can usually be done by anyone with modest DIY skills.

First, remove the ice maker by loosening the screws on it and prying it away from the unit. Take note of how it is connected to the refrigerator, as this will help you know where to reconnect it when you are finished. Once you have removed both parts, take them outside and hose them down. This should remove any accumulated algae or minerals that may have built up inside them, and will also remove the “musty” smell that refrigerators get when they are not used for some time.

Once you have brought it back in, clean both parts with dish soap to remove any grime or mineral deposits. After cleaning, test for leaks by plugging water into the new line. If it does not leak, then you can reattach them to the unit. Make sure that the supply pipe is clamped at both ends before beginning this task. When screwing on new lines, always tighten your connections firmly, but do not over-tighten as you may damage the pipes.

If your refrigerator did not come with a repair manual, you can find one online. If you cannot get it to work by following the instructions above, then consulting an appliance repair like Nationwide Appliance Repairs person may be your best bet. However, if mechanical failure or user error is not responsible for your refrigerator malfunctioning, such as if the unit has been unplugged for a long period of time, then it may be getting ready to quit working altogether. If this is the case, turn it off and unplug it immediately.

Upgrade your refrigerator’s insulation by taking out old foam with a screwdriver or knife and replacing with new foam. This will block out up to 40% more heat from escaping.

Finally, if your refrigerator is not getting cold enough and you think it could be due to a thermostat problem, then try replacing the thermostat yourself. Make sure that the new one has exactly the same number of wires as the old one before beginning this task. You should only attempt this repair if you feel confident in your ability to take apart and reassemble a unit.

If you cannot get your refrigerator to work, first check to make sure it has been plugged in before calling a professional for help. If there is no water or ice from the dispenser, then this means that the line needs to replaced, which can be done by any homeowner with some basic repair skills. Unplug your unit and take the ice maker out of the refrigerator so it can be cleaned outside. If you need more help or if you would like to know how to replace a faulty thermostat, consult an appliance repair manual available online.
