SOURCE: Amana Cooling Condensing Unit fan stops spinning after 15 mins
Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

be aware that not repairing this asap that you are causing yourself more problems First I would change out the fan capacitor and see if this could be the problem. Secondly if the capacitor isn,t the problem change out the motor . By continuing to allow the system to cycle like this the compressor will take a dive on you costing more . Good Luck

Testimonial: "Yes, it's dual run capacitor problem. I used a stick to spin the fan blades and it starts to slowly spin and up to normal speed, so motor is good."

If this unit has the old style control with the knob instead of the digital control panel
then I would suspect this first. This is the first component to fail on these units. I have
replaced two already and the kit has good instructions and all components.
Takes approximately an hour to do and mount the new sensors. (The transformer is
hidden beneath the sheetmetal just below the control board). You should be able to order this kit through any appliance parts store for around 175 dollars versus almost
800 dollars for a new PTAC. Hope this is helpful.
