My upright freezer runs more than it is off

SOURCE: Freezer Problem

If it started to cool again the compressor was running. Check the condenser and make sure it is clean. Provide as much air movement through the garage as possible . 100 degrees is a high temperature to be operating a refrigerator in.

SOURCE: My freezer's defrost systems runs constantly

i dont think so i would look at the compressor kicking out on thermal overload or a faulty thermostat thermostats have two settings cut in cut out your cut in could be bad and not turning the compressor on till the temp reaches melting temps now if your hearing a click buzz then you need to look at the compressor and make sure the compressor fan is running but its not a defrost promblem

SOURCE: Running continuously

Hello bxrjer,
Welcome,

You said, you have a FFU20FC6AW2 freezer that I have noticed is running continuously. Explains my $400 electric bill.


How old is the freezer?

The thermostat may be faulty.
But check out this list first.

If the black tubes running back and forth that carry the freon is under the freezer and behind the plastic grill down near the floor you may want to remove the grill cover and gently run a refrigerator brush across the coils. Ive seen them never cleaned and full of lint and dust 2 inches thick.
This is not good for the freezer or any refrigerator too!
They need to be clean so air can run across them or they over heat and get hot.
Room or outside weather is hot. It is normal for the freezer to work harder under these
conditions.

Reasons why Freezer may run too much or too long.
1.Freezer had recently been disconnected for a period of time. Freezer requires 4 hours to cool
down completely.
2.Large amounts of warm or hot food have been stored recently. Warm food will cause the
freezer to run more until the desired temperature is reached.
3.Door is kept open too long or too frequently. Warm air enters the freezer every time the door
is opened. Open the door less often.

4.Freezer door may be slightly open. (Freezer is not level. It rocks on the floor when it is moved slightly. This condition can force the cabinet out of square and misaligned the door.Freezer needs to be leveled if this occurs.
Floor is uneven or weak. Freezer rocks on the floor when it is moved slightly. Level the floor by using metal or wood shims under the freezer or brace floor supporting the freezer.

5.Temperature control is set too cold. Turn the control knob to a warmer setting. Allow several
hours for the temperature to stabilize.
6.Freezer gasket is dirty, worn, cracked, or poorly fitted. Clean or change gasket. Leaks in the
door seal will cause freezer to run longer in order to maintain desired temperature.

Sounds like the timer could be getting stuck and not releasing the defrost cycle

SOURCE: I bought a used Kenmore upright freezer, it's been running all the time.

I'm Not a pro, but the comments refer to a refrigerator. I don't think they read your problem from start to finish. I went to RSI in Phoenix, and I would say it is low on refrigerant. I hope it's 134a.
Good Luck
Over the years the freon sloowly leaks out, it might need only an ounce or two but it will fix it in my opinion. I have the same problem with mine.
