My Frigidare upright freezer #lffu14f5hwj not cooling. I put freon in @2psi. Replaced defrost sensor . Compressor runs all the time and very hot to the touch. Control board works with up and down temp. Also will cut unit on and off. Could this be the thermosistor? What ohms should it read? Please help,. Warm regards,. Rom
@Ronald Lee The thermistor will only stop or start the compressor (via the control board) once the temps are cold enough or if it warms up. If the compressor is running all the time and the temps aren’t even cold then you will have to get the proper equipment to measure the pressures in the sealed system to know whether it is a compressor problem (not pumping) or a lack of refrigerant. Depending on your location you may need a licensed repairer as where I am you’re not allowed to even buy refrigerant without a license due to the environmental regulations regarding the handling of refrigerant gases. Usually you have to cut into the sealed system to connect valves so that the equipment can be connected etc to measure the pressures but your model may already have them
