20 Most Recent Frigidaire Freezer 20.3 Cu. Ft. Frost Free Upright Freezer, AFFU2066D Questions & Answers

Is it freezing properly to zero degrees F? Noise could be bearing in evaporator fan motor, or compressor itself.

Had the same problem, I unplugged freezer for two days, pluged back up, has worked fine since.

You have a bad t'stat. Can you turn it it upborcdown.

You should be able to set the unit up to 30?F and still freeze some contents.

Turn the unit off by the circuit breaker for about 10 minutes and retry the unit again.

Your defrost timer has stuck to on position, replace timer and all good or locate timer and spray lubricant into the dial and turn it several times with unit off, then try it after several hours, quick fix only but may last several years...good luck...Russ

The unit is not at correct temp, ""unsafe to keep food"". Needs service.
Hope that helps. Russ.

If you remove all the items from the unit and defrost it for 2 days with door open, on restart, should work fine..

I have had the same problem with my frigidaire/electrolux upright freezer... I am researching to see if there is a pattern. Once or twice a year for the past few years, the freezer defrosted itself. I found the outside of the unit to be VERY hot to the touch around the time that this occurred.
We typically unplug it for a chunk of time when this happens and then replug it. It has always begun working again.
Sadly, we have lost many groceries and have had to clean many bloody meat messes as a result of this. ANYONE buying this freezer should save their receipt... That way, they can return it or have it repaired when it fails. I hate to think of sending all of these failing monstrosities to the landfill... =(

Without any additional info, there are a lot of possibilities:
1. Condenser coil (underneath unit) is dirty and clogged.
2. Compressor is failing. (need A/C tech)
3. Metering device is clogged. (need A/C tech)
4. Refrigerant charge is low. (need A/C tech)
5. Door seal is broken (frost will form around door).
6. Defrost heaters are stuck on (replace defrost timer located underneath unit at front).
7. Condenser fan has failed (underneath freezer on back).
8. Evaporator fan (inside fan) has failed (ice will form on cooling coil).

This should get you started...

If this helps you, please select YES to the first two ratings questions. Thank you, and Good Luck.

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

The error code -H9 on a Frigidaire upright freezer typically indicates a communication error between the control board and the display board. To troubleshoot this issue, try unplugging the freezer for a few minutes, then plugging it back in to see if the error code clears. If the error persists, it may be necessary to replace one or both of the boards. Contact a qualified appliance repair technician for further assistance.

According to the Frigidaire website, the cubic feet for the Frigidaire stand up freezer model MFU23BW4 is 23 cubic feet.

Many reasons why it may be loosing temperature. Such as Defrost problem, fan not running, sealed system problem, compressor problem
