ac central air fan motor doesn't run when outside temp is HOT, what causes it to stop running?

Answer:

MOST likely a bad capacitor. Call a pro, the repair should not exceed $200. (IF it's the cap)
In a automobile the fan motor runs from the battery at the same time as the A/C compressor runs from the engine. The A/C fan motor runs each and every time the vehicle's fan swap is placed in between the ON positions (and the secret's 'ON', and so on.). typically the person ought to decide on the Snow Flake image on the dashboard to exhibit on the A/C. even with the indisputable fact that, except the engine is operating the A/C compressor isn't doing the paintings mandatory to make chilly air (except the A/C extremely runs also at the same time as contained in the defrost position on the that different fan administration knob). in case you decide on the snowflake image and the fan is ON and the engine is operating and the ignition secret's on and also you're literally not contained in the defrost position and also you do not have some type of fault contained in the device then you actually ought to get chilly air out of the vents provided that you actually have the temperature slider set to grant chilly air too.
If its due to the temperature than it may be shutting of on thermal overload protection inside the motor, likely the the bearings are bad / amp draw is higher than rated and the added ambient heat is enough to trip the overload. So the fix would be a new motor. Now not to be but you wouldn't be the first homeowner to mis-diagnose their a/c problem. It could be something as simple as a capacitor and the temperature has nothing to do with it.
CHECK THE FUZES in the box near the outside unit. Kill the main breaker before you touch them it will send you to the morgue !
