			closes at 120° F and opens at 100° F). With the
			cooling fan thermostat preheated, check for
			continuity. If switch is open, replace thermostat.
	Cooling fan		Line voltage should now be at the cooling fan.
			If voltage is present, check motor for shorts or
			opens. With power off, check for locked rotor.
Control box cooling fan	Cooling fan thermostat		This normally open thermostat should close at
continues to run			120°F (48.9°C) and reopen at 100°F (37.8°C).
