Location. Temperate grasslands are located north of the Tropic of Cancer (23.5 degrees North) and south of the Tropic of Capricorn (23.5 degrees South).The major temperate grasslands include the veldts of Africa, the pampas of South America, the steppes of Eurasia, and the plains of North America.limate. Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
In summary, certain conditions can force a heat pump into a defrost cycle (or cooling cycle) where the fan in the outdoor coil is stopped, the indoor fan is stopped or electric heat is turned on, the frost melts and is removed from the outdoor coils.
The number one reason why a fan motor will fail is because the air cooling the windings of the motor is superheated. All the air cooling a typical outdoor air conditioner fan motor is hot. The air first passes through the outdoor condensing coils where it picks up heat and this heated air cools the fan motor.his leads to the fan motor heating up and this leads to failure. Often when replacing an outdoor air conditioner fan motor the unit must be cycled and tested for proper air movement. If the fan blade is positioned backwards (I have seen this many times) the fan blade will move air, just not a lot of air.
