Freezer defrosted and the motor won't start back up.

Possibly a problem with one of the components in the automatic defrost system in the freezer then.. this is the only reason why the alarm would keep sounding. Perhaps some of the moisture from the defrost has gotten in and damaged the electricals somehow. It might be worth it to store your freezer contents elsewhere and completely defrost the freezer and then heat the inside cabinet up with a hair dryer or something similar. This will dry out the cabinet and the electrical components. Once the freezer has warmed up let it stand for as long as possible with the doors open so that it reaches room temperature and then close the doors and switch back on. If this doesn't work you probably need a service engineer visit.

THE UINT IS FROZE UP, YOU WILL NEED TO DEFROST IT. USE A FAN TO BLOW INTO THE FREEZER PORTION , AND HAVE LOTS OF BIG THIRSTY TOWELS HANDY .. THIS WILL TAKE ABOUT 2 HOURS TO DEFROST, WIPE EVERY THING INSIDE THE UNIT DRY !... JAY THE POOL PUMP MOTOR REPAIR GUY FLORIDA

keep the door closed by all means any small opening can leave the freezer start to defrost slowly without you knowing it

I've worked on freezers for over 20 years and have never heard of a compressor going bad because the door was left open. think about a second opinion.
Also, has the cooling coil inside the box developed and frost or ice build up? If so, it needs to be completely defrosted. If you defrost it manually, use a hose hooked up to hot water. Kill all power and hose all build up off. Remove the sheet metal housing ends and be sure there is no ice inside there too. I would go in this direction first.
IN order to kill a compressor under this condition, something really strange must have happened as anything is possible in a refrigeration system. Good luck and hope this helps.

It is probably the control board and since it's new it's still under warranty so a certified Frigidaire repair man will fix it without charge. There should be a telephone number with the paperwork you received when you bought it.

My wife solved it for me :-) You turn the alarm off with a switch at the bottom. The alarm turns off, but the light stays red for another 4 hours. After that the red light goes off too, and you can turn the switch back on without the alarm going off, if the freezer is back to operating temp.

The excess frost in those areas is probably caused by leaky door gasket seals. They should be tight enough to hold a dollar bill securely all the way around. A defrost problem would start on the coils behind the back cover inside the freezer and would also appear on the back wall before it did on the door edges.

Having the door open has introduced an excess of humidity and therefore condensate/ice into the freezer coils. The coils are therefore iced over. You have choices depending upon your skill level. You might: allow the unit to sit unplugged with the door open until the excess ice thaws out and wets the floor underneath, which may take from 6 to 24 hours. You might: do this, adding some heat source in the freezer to accelerate the process. You might: locate the defrot timer, advancing the timer until a click is heard indicating the unit is in defrost, and repeat after about 15 minutes to defrost the unit with it's own heater. You might: let it recover just as it is but it will take a couple of days to clear itself.

After looking at some advice from others I turned the internal dial to the OFF position, then turned it back to 6 or 7, and left it for 20 minutes, and it is now freezing again.

Was the door left open for a long period of time.? Sometimes this causes so much ice that it re freezes and can't clear the drain. The only solution is to unplug and let sit with doors open for at least 24 hours. to get all the ice off the coils. Then use a pipe cleaner on the drain then use a turkey baster to force water through. then a mild bleach solution. Check the door gaskets if they are ripped or loose or the door warped and not sealing tight this will also cause this problem. If this still doesn' t solve the problem it is probably a defrost problem Usually the timer or defrost thermostat.
