Mell Why does my air conditioning run at only one speed?
When a blower resistor fails, the highest fan speed usually is the only one that still works because it essentially bypasses the resistor and receives the maximum amount of voltage. When the resistor is working, it reduces the amount of voltage going to the lower fan speeds, so the fan runs slower.
How can I increase the speed of my AC fan?
Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home more effectively and remove more moisture from the air because of slower air movement through the cooling equipment.
What happens if you run your air conditioner fan too fast?
Watch out: running the blower speed too fast during air conditioning may result in inadequate dehumidification, while running the fan at too-slow a speed may result in ice blockage on the cooling coil. The blower fan motor in most air conditioners has three speed settings – low, medium and high.
Why do I need to set the fan speed?
By slowing the air movement through the cooling coil the system will remove more moisture from humid air than would occur if the blower moves faster because the faster air movement more quickly cools the room down and thus reaches the set temperature on the thermostat. In other words to dehumidify we may need to run the system for a longer time.
How does low fan speed affect the efficiency of my air conditioner?
Using Low speed on fan will cool your room slowly at a lower noise – both ways costing the same electricity in the end. I apologize if ive made a fool of myself and did this totally wrong. Hope it helps. The fan and compressor units are usually driven by separate independent motors.
What happens if the blower speed of an AC unit is too high?
If a blower speed is set too high, your AC might not be operating optimally. This is because the evaporator coil will not be able to adequately dehumidify the space in need of cooling. On the other hand, if the blower speed is too low, your evaporator coil is at risk of “freezing.”
