Is this freezer manual defrost or frost free?

Hello friend, thanks for your post!

If you Frigidaire freezer is frost free and not defrosting the best thing to do is to manually defrost your appliance. You can do so by disconnecting power from your freezer for two to four hours. If you have a frost free freezer you could be experiencing an issue with thermostat or sensor and they may need to be replaced.
I would recommend reaching out to a professional to come out and diagnosis your freezer to avoid any unnecessary part purchases. I hope this is helpful. -Matt

No it is not frost free. You can get the manual on the link below to read about the freezer and learn how to defrost.

Good Luck and please rate 4 thumbs up for the free answer.

Check rear wall of freezer by feel for frost. Heavy, even frost indicates likely problem in the defrost system. Unplug unit. Defrost heater (in freezer behind rear wall panel), defrost thermostat (same area-must be checked at freezer temperature) or Defrost timer-located lower back outside of unit. Near compressor. Do continuity test on heater and defrost thermostat and if they show continuity (good), replace defrost timer. If not, replace the one that tests bad.

Defrost coils fully. Reassemble.

Please let me know if I have helped with comments and rating.

Refrigerator will work about 7-10 days after being defrosted until thick frost builds up again cutting off air flow to both compartments

replace defrost timer pcb.

I am not aware of a chest freezer that is auto defrost.Go ahead and defrost it like you would any chest freezer. Eric

This is a common problem with these units. especially in high humidity places. You will need to do a manual defrost to fix this. Also make sure that it is doing its defrost when it shuts down each day. Hope this helps. Good luck.

Your defrost timer, switch or circuit board is probably shot or it would be defrosting.

Use a fridge / freezer thermometer to tell if temperture high (it should be 0 F plus or minus 5 degrees) to determine if it is too high - this is normal if frost builds up but will get worse unless repaired.

You have a defrost parts issue.
Unplug the fridge. Remove the back freezer panel and check the defrost heater and defrost thermostat.
Without a model number I can not tell you where the defrost timer is.

An upright freezer that is not frost free will have the coils in the shelves (shelves are non-removeable) and that is where the frost will buildup.  If your model is like this then it will have to be defrosted periodically.  If your not sure then give me the entire model # from the sticker inside the freezer and I will look it up for you.

possibly due to not defrosting. take off rear panel in freezer and check if there is ice build-up on the evaporator. if so, melt off carefully with a hair dryer and appliance will then work. get back to me with what you find if you wish
