Error code HA, I need a list of error code explanations.

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.

Hello Friend, this is Z. I am happy to assist you!

I see that your question is listed under Frigidaire Upright Freezer; however, please help me understand the issue you are experiencing. Is your freezer showing error code OFF? If so, the temperature control is in the OFF position. 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 your freezer by pressing the UP arrow until display shows "4" or desired setting. Please allow 24 hours for temperature to stabilize. For future reference you can lock the control to keep from accidently changing the temperature setting. I hope these troubleshooting tips help you in some small way. 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 your freezer status has changed successfully.

You need the owners manual for that specific machine to get the listing of its error codes.

Good Afternoon Glenda, thank you for your inquiry!

Is it possible that the error code is missing characters? According to my research 8 is not a valid error code. The number 8 is more like a temperature setting, however to be certain, let's try resetting the appliance. It is important to wait roughly ten minutes and then turn the unit on. Set the correct temperature and please allow 24 hours for the temperature to stabilize. The error code should clear and the unit resume to normal operations. 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.

Best regards!

Hi,
hope the following helps you, I had a similar problem with my RSH1 and it took me a few hours searching online before I found the following.
"Hi, I have it on good authority that this is the system check for Samsungs (RS21, SRS20, etc) during normal operation, is to hold the top two buttons down, just until display flashes - this will reset the electronics.
Secondly, if the top two buttons are held down for longer (8 seconds) the display goes blank and will show any error messages in the form of DASHES
I have experimented with unplugging air or frost probes - and the error code you get -on a blank screen is different parts of the last digit lighting up.
Example: when i disconnect the fridge air-probe, shut both doors, hold down top buttons around display - The SIDE of the last "8" digit lights up ! ...strange but true.
But, I need to know what it means when the BOTTOM of the "8" digit lights up"

I am still trying to find a list of the error codes the lines refer to but so far my unit is working fine.

There should be a reset button on your control board inside the electrical compartment.

Turn the system on to ice mode and depress the reset button. This should clear out any and all faults stored in the board and the machine should at least attempt to come back to life.

Look on the outside of the electrical compartment cover. There should be an explanation of what your error code means. I can't remember it off the top of my head. But the list there will tell you what 1 beep every 305 seconds means and the procedures to take from there.

Wow, what a challenge.
I found what I think you are looking for.
First, this only applies if the controller is an MCII. Should be printed on the face of the control.
In their 1996 manual for 6000 series reach-ins, it states that the number "4" error code is "Continuous operation with overtemp condition." It also says "What to do." and lists "Check refrigeration system and control system."
Hope this is what you are looking for. Good Luck.
