My Frigidaire air keeps beeping and now does not work display says 0.5 what does that mean

means you need to replace the panel

Good morning jesse dixon, I appreciate your post!

Based off the information you have provided your Frigidaire air conditioner, FRA123CV1, cutting off every three minutes and then flashes "#88" then it will go back to the normal setting. Sounds it could be a possible issue within your control panel or power cord. Are you currently under warranty? If so, you might want to reach out directly to the manufacturer to determine the coverage on your air conditioner and the procedures to any potential remedy. I hope this helps to some degree. -Matt

Fridge keeps beeping or buzzing: The following is for Frigidaire models but others can be addressed similarly.

Several Frigidaire refrigerator models have an electronic control panel on the freezer door the owner can use to adjust the internal temperature, dispense ice and water and receive notification about issues such as the need to replace a water filter. The refrigerators also emit a beep for various actions and as an occasional alarm. Determining what causes the beeps necessitates some troubleshooting.
Temperature Controls ·A Frigidaire refrigerator's display panel blinks when the control panel is touched to set temperature controls. After pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, press the arrow buttons within five seconds to increase or decrease the desired temperature. If you do not press the arrow buttons within five seconds after pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, the refrigerator beeps to indicate the current setting will stay in place.

Door Open ·When you leave the refrigerator or freezer door open, the refrigerator beeps. Also, the "Door Ajar" indicator illuminates on the appliance's display panel. Shutting the door and pressing "Alarm Reset" stops the beeping and turns off the "Door Ajar" indicator light.
·The Frigidaire refrigerator has a control lock feature that prevents use of its control panel or dispensers when the unit is locked. When the control lock is active, a beep sounds when a keypad or dispenser is pressed. Release the control lock by pressing the "Control Lock" icon for three seconds. A beep will sound, and the icon's light will go out.
Power Reset ·A power reset is occasionally necessary if the Frigidaire refrigerator's control panel does not work normally or a reset function on the keypad does not work. A power reset involves disconnecting power to the refrigerator by unplugging its power cord from the electrical outlet, waiting 30 seconds and plugging the power cord back into the electrical outlet. When the control panel resets, a beep sounds. If the refrigerator beeps even after a power reset and the beeps' source is not known, contact Frigidaire.

Cause of Beeping Noise in Frigidaire Refrigerator eHow

Hello Pete T - From what you have described the air conditioner possibly have a defective power/control board or faulty plug. I would suggest contacting a professional to accurately diagnose and repair the unit.

Clean the unit, clean the filter, reset the GFI plug if you have one, and then try again. If you continue to have the same problems, contact Frigidaire and see if you have any limited warranty on the appliance.

Is everything dry? Do you hear any noises like the compressor running it is just not cooling?

Have you recently plugged in another appliance (computer, microwave, etc)? The drain on your home's wiring system may not be allowing all appliances to run at once.

P 4 code means problem with the outdoor unit, Most likely low on refrigerant. Check all copper pipe connections for leaks first, then add refrigerant after checking pressures.
