P-1 code is flashing on temperature display - True 72 cu. ft. / 2039 liter Commercial Freezer T-72F

LOW / NO BATTERY ALARM
The Low/No battery alarm will activate when the
power level of the battery becomes low. The display
will alternate between "b" (Battery, See figure 8) and
the cabinet temperature, the red alarm light will
become illuminated and the control panel will beep
every five seconds. To stop the audible alarm (beep),
press the "ALARM RESET" button. The red alarm
light will remain on and the display will continue to
flash until a new battery is installed. This same alarm
will activate if there is no battery installed

The beeping is typically a code. Is there an addition of a led flashing anywhere you can see?

Well, no, actually. P2 is an error related to the evaporator temperature probe. I would start with the electrical connections, the bond between the probe and the evaporator, and the evaporator fan.

Hi Rachel
For your door to close properly take off the gasket from your fridge and wash it with hot water. It will be softer and stick to the fridge much easier.

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.

If unit keeps proper temp. then I would think that either the thermometer sensing probe may have been damaged during the repair process or the thermometer itself has failed.

Have a look at the Make and model of your thermostat and download the Instructions from the internet or give ur local refrigeration mechanic a call and ask him they are easy to set

It means the compartment temperatures are increased then allowed limit.Generally in some appliances the maximum temperature is indicated at the display with an alarm after the electric cutoff.If the temp is high in the compartments
