Question about APC Air Conditioners
Was working then stopped no power to head unit does this model have a reset button or inbuilt fuse?
SOURCE: my problem is with frigidaire
I am not too familiar with these systems but, it sounds to me like it may be in a safety lock out mode.

Turn off while running and then turn back on again, causes electrical control circuit system was malfunctioning due to overload relay trip off and then this will trigger on when the load was cold setting the unit run again.Overload tripping off due to there's a high current flowing in the circuit w/c is higher than the rated current specified in the unit.Several factors may be consider the head unit is developing hi pressure that causes electrical circuit malfunction.or the thermostat is defective or some thermostatic valve is mulfunctioning.

Check the circuit board inside the indoor unit. Some time moisture in this circuit board can miss lead the functions of the board. Heat the board with hairdryer . Also check the coil sensors and the Room temparature sensor Connected to the board. If any one is faulty this type of problem can occure. Remove the two sensors and check the value of the same witha an OHM meter. The two sensors will have the same vaule at room temparature.

If your condensing unit has coils that are bent, they should be straightened out as much as possible for proper performance of the unit. You cannot straighten the fins properly without a special tool called a fin comb. These tools come in a variety of styles including single, multiple or interchangeable heads having different fin comb sizes and counts to best match the coil fin size of the repaired unit
sincerely. God bless you

Tips for a great answer:
Thanks for the post, friend!
I understand that the compressor continues to run after your Frigidaire air conditioner has turned off. From that information it sounds like there could be a possible issue within your control panel or relay. I would recommend a reset on the appliance, to perform a reset unplug the power cord you will see a test button, push that button and you will hear a click. You would then press the reset button you will hear a click again signifying that the appliance has been reset. Then plug your air conditioner back in. If you continue to have an issue with your compressor I would seek assistance from a professional. Hope this is helpful. -Matt

6 - DC Peak Error
• Supplied power is not normal
• Comp Connector (CN-U,V,W) is disconnected or inserted to wrong
• Compressor is damaged (coil short) ? replace compressor
• Too much Refrigerant
• Defect in outdoor pcb assembly ? replace pcb assembly
Try turning power off to external unit, usually resets diagnostics and runs OK. If not PCB external unit likely culprit, replace!
