Freezer will not turn on

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.

The manual for this unit can be found here.

Good Morning Stephanie Garcia, thank you for your post!

From the information you have provided your Frigidaire freezer is displaying an error code of "OF". Typically, an "OF" stands for power off, you should be able to press the up arrow three times in a row within five seconds to turn your freezer back on. If that does not help correct your issue you may want to perform a reset and you can do that by unplugging the power cord for roughly ten minutes. I hope this helps. -Matt

Hey friend, thanks for your post!

From my understanding you have recently moved your Frigidaire freezer and it is now displaying the "OF". Normally, that stands for off you should be able to press the "Up" or "Down" arrow three times within five seconds to start your compressor. If you still need a copy of your manual could you provide me with your model number? You can locate your serial tag (which lists your model number) on the inside wall of your freezer. I hope this has been helpful. -Matt

Unplug freezer to reset, if display still says off when plugged back in and will not change then I would have to say the t-stat/board is done for and will need to be replaced.

Hello Michael - Sounds like the temperature control was accidently turned OFF. When this occurs the temperature control turns off the compressor, but does not disconnect the power to the light bulb or other electronics. Let's try activating the freezer by pressing the UP arrow until display shows "4" or desired setting. Allow 24 hours for temperature to stabilize. For future reference you can lock the control to keep from accidently changing the temperature setting. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully. Thank you.

Otherwise it would never stop freezing. Let me know what you find out.

Download its manual here and then read through the defrost section. It should run every 12-24 hours.

did you press and hold the freezer off symbol for three seconds

change out the main control unit.there could also be a crossed or shorted wire in the door and this can not be fixed
