Question about Broan-NuTone N-RF69NR Attic Fan Attic Fan
My attic fan starts to turn but stops, it appears to be over loaded and then waits a while and does it again. Is this a problem with the motor, the capacitor or the temperature sensor? Model # RF-69NR

Check power from the t-stat to the motor or relay depending on how yours is configured for control voltage. If power is present at the motor. You will need a meter that can read amperage, take a ampdraw on the leads of the motor. See what this reading is, on the motor there should be a rating for LRA (locked rotor amps) if the amp draw exceeds this reading your motor is bad. You may also have a split phase capacitor installed which helps start the motor is so and you have a meter that reads in micro farads you could check the capacitor. the symbol for mico farads looks like a uf. Just make sure you discharge the capacitor to ground with a screw driver or insulated tool, if not it will shock you severly. Another thing you might look for is a reset button on the motor. Most likely this will be a red button somewhere near the bottom side of the motor.
