Compressor keeps running after turning unit off?
Bad relay board LG and Frigidaire have this problem
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

The compressor is probably going out on either a pressure related or heat related overload. Both are a result of low refrigerant. There may be a low pressure safety swich that protects the compressor. Otherwise it may be an internal thermal overload that is tripping. It resets itself and comes back on. The thermal overload heats up and shuts off the compressor to protect it from too much heat which is gernerated by not enough refrigerant in the system to keep the compressor cool. It may be cheaper to replace the unit than have someone try and fix it. It is pretty time consuming and you cannot try it yourself unless you have an EPA Certificate to buy the refrigerant. Check with your local appliance repair man to see if he will tackle it.
6 - DC Peak Error
• Supplied power is not normal
• Comp Connector (CN-U,V,W) is disconnected or inserted to wrong
position
• 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!
