Many homeowners love their chest freezer for the extra storage it provides, but it can be a real headache when it malfunctions. Follow these steps to identify why your chest freezer is broken so you can fix it as quickly as possible.

Tools and Materials Needed:



* Screwdriver

* Electrical Plug

* Hinges

* Multi-tester

* Light / Fan Switch



Step 1 - Inspect the Door



If your chest freezer door does not shut properly, it could cause the temperature inside the freezer to rise, making the thermostat work overtime to correct the problem and eventually burn out. Another issue is if the door does not shut correctly it no longer depresses the internal light switch, causing the light to remain on and heating the freezer that way.



If the door is askew, you will need to replace its hinges. If the door alignment is fine then inspect the light switch. To replace a faulty light switch, shut off the chest freezer and pry the switch from its housing. Then disconnect the wire (s) from the switch and connect a new one (you can purchase a new light switch in any home improvement store). Replace it in the housing and plug the freezer back in; the freezer should then be back to normal.

Step 2 - Check the Outlet and Plug



The fact that there's no electricity running into the unit could be why the freezer has ceased to function. Unplug the freezer and look at the plug; if you see it's singed or burnt, replace it immediately. If the plug looks okay, insert it into a different outlet. If the freezer starts up again, you know the problem lies with the original outlet.

Step 3 - Examine the Thermostat



A faulty thermostat could kill a chest freezer. You can test the thermostat with a multi-tester, but if you don't have one or don't feel comfortable testing this piece of the machine, call in a professional repair person to have a look.



You can get to your thermostat by the side of your chest freezer (you'll need a screwdriver to get to the part). If you see the coils that run from the thermostat into the freezer have frosted over, that is a sure sign there is something wrong with the thermostat. A thermostat replacement is not a hard job for a professional so it should not cost a lot to have someone do it for you.

Step 4 - Manual Defrost



Another reason your chest freezer may have stopped working is that the defrost mechanism could be faulty. You will need to manually defrost your freezer to re-start the defrost cycle. Remove the food from your chest freezer and turn the thermostat off. Open the freezer door and place towels on the floor in case the ice melts at a rapid pace. After 24 to 48 hours most of the ice should be gone and you can turn the thermostat on again. If the chest freezer then begins to work, there is a fault with the defrost unit and it is time to call in a professional.
