What could cause My haier chest freezer to quit working

SOURCE: freezer freezes but does ever stop running

thermostat is stuck on! set to medium setting and gently tap stat. does it turn off? it was stuck. does it still run? its still stuck. if you feel comfortable find stat and power in and out. disconnect - it has to turn off then. but 99 % of the time its the stat. they fail closed and run 24 -7 or fail open and temps get real hot and they never close and restart compressor . yours appears to have failed closed. sometimes you can firmly twist em max cold to min cold a few times and break the stuck contacts and they'll do ok for a while. try to reset at a little higher or warmer temp when done so its not making and breaking on the same old worn spot again. good luck.

Yes it does. It will have to be blowing inside so look in there. You will have to take the cover off.
Sometimes they stick and need a shot of WD 40 and then work
it back and forth a little until it wants to take off again. Keep me informed
and PLEASE give a Thumbs Up for the effort. The Raz Shack

Do not put a towel on your freezer or anything that could prevent a good seal from top of freezer.

SOURCE: Small Kalvinator chest freezer quit working,

If not running then jump out thermostat. If running then throw it out as it has a sealed system issue not worth repairing unless it is under wty. I cannot see your repyl due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

Hello
Due to the heavy storm you experienced,and since the freezer was plugged during that period there might have been a negative effect from the storm on your freezer due to earth.All you need to do is to get a technician to check it out.
THANK YOU
