Freezer Troubleshooting & Repair

WHAT
IS WRONG WITH YOUR FREEZER? |
| It
doesn't work at all It's not cooling It cools poorly or it's all iced up It's noisy It doesn't cycle off Learn more about freezers Freezer parts |
| Note: Most chest and upright freezers require manual defrosting. These freezers have significantly fewer components--and therefore fewer problems--than self-defrosting freezers. |
| Does the light inside
the freezer work? Or, can you hear a fan, motor, or other sound
coming from the appliance? If so, the freezer is still working.
Go to the specific problem you are having with the appliance.
If not, try adjusting the thermostat to a colder setting. If your
freezer still doesn't work, read on. To check to see if power is getting to the freezer, plug a lamp or other device into the same outlet as the freezer. If there's power, check the fuses or circuit breakers. If that's not the problem, contact a qualified electrician to restore power to the outlet. If there's power to the freezer but it still doesn't work at all, there may be a problem with one of these:

If the freezer seems
to be doing nothing, see the "It doesn't work at all" section,
above. Otherwise, check these:

| If your freezer cools
but doesn't get cold enough, it may have a problem in one of several
areas. To better understand the proper operation of a freezer,
read about freezers in the How Things Work section of our website. In a self-defrosting freezer, poor cooling often results from a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel inside your freezer. But if you see any frost or ice build-up on the inside walls, ceiling, or floor of your freezer, it's a sure sign of frost build-up. And that's a sign of a problem with the self-defrosting system. Freezers should self-defrost three to four times in 24 hours. But if a component in the self-defrosting system fails, the freezer continues to try to cool, instead. Eventually, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There's still some cooling because the coils are frozen. But with no air flow over the coils, the cooling is quite limited and the freezer isn't as cold as it needs to be. An easy (though often inconvenient) test of whether the problem is with the self-defrosting system is to remove all of the perishable food from the freezer, turn the thermostat to Off, and leave the door open for 24 to 48 hours. (Keep several towels handy in case the melting frost and ice overflows the drip pan). This "manually" defrosts the freezer. When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the freezer then cools properly, it indicates a problem with one of these components in the self-defrosting system:
|
| Noise can come from
these areas: The inside of the freezer The outside back of the freezer The bottom of the freezer |
Your self-defrosting
freezer uses a circulating fan to move the air throughout the
freezer. It runs whenever the freezer is cooling and the door
is closed. The fan is located in the freezer section, as follows:
|
This area has one component--or
two, if it's a self-defrosting freezer:
|
| Noises here are almost always actually coming from the back of the freezer, see the "The outside back of the freezer" section, above. |
| The thermostat cycles
the freezer on and off. The cooling system runs as long as the
temperature inside the freezer is higher than the set temperature.
If the temperature inside the freezer is cold enough, but the
thermostat doesn't cycle off, the thermostat may be defective.
If so, you need to replace it. |

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.
