Which way should a condenser fan spin?
Which way should a condenser fan spin?
Lay your fan blades flat on a table or the floor. You should notice that there is a portion of the blade that is raised: this indicates the fan’s direction. If the right side is raised, it should spin clockwise. The left-side raised means it turns counterclockwise.
Is my fan blade CW or CCW?
Look at the blade that is in the 12 o’clock position. One side of the blade will be resting on the floor and one side will be raised. – If the Right side is raised, then your fan is Clockwise. – If the Left side is raised, then your fan is CounterClockwise.
Does a condenser fan push or pull air?
The fact that it is mounted in front of the condenser-radiator means it must PUSH the air through the cooling pack.
Why do condenser fans spin backwards?
Your capacitor is too small. The new motor you list requires a 10 MFD capacitor to run at 240 VAC. Since the OEM capacitor in the unit is only 5 MFD, the new motor will randomly run backward and it will run with far less than its rated HP. Also, you should connect the new motor to run on LOW (red wire).
Can you put a fan blade on backwards?
A word about installation: It is possible to install an engine fan backwards. Contrary to popular belief, a fan installed backwards does not move air in the opposite direction.
Can a AC compressor run backwards?
Is it possible for single-phase scroll compressors to run in reverse direction? Yes, brief power interruptions during compressor operation may cause this.
How do I know if my motor is CW or CCW?
Basically CW (clockwise) and CCW (counter clockwise) motors are still the same motors, apart from the prop shaft threads which have opposite direction. That means for a CCW motor, the prop nut is secured by turning clockwise. And for CW motors, the prop nuts needs to be rotated anti-clockwise in order to fasten.
What does rotation CWLE mean?
For example, a motor stamped “CWLE” means its rotation is clockwise looking at the motor from the lead end of the motor; “CWSE” means clockwise rotation looking from the shaft end.
What kind of fan pushes air through coils?
condenser fan
A big, often loud condenser fan helps to push air over the condenser coils to facilitate heat transfer outdoors.
What happens when a compressor runs backwards?
Unlike reciprocating compressors, scroll compressors do not operate properly when run in reverse. If left unprotected, extremely high temperatures, adverse oil flow conditions and unusual pressures can damage components. The mechanisms causing these adverse and potentially damaging conditions are explored.
Are condenser fans interchangeable?
They are not interchangeable. If you can’t read the label on the old motor, take it apart and look at the number of poles.
What happens if fan rotates in opposite direction?
When you put the fan into reverse, it draws air upward. Most people think of this as a way to bring the warmer air near the ceiling back down into lower half of the room, where the people are. That’s a great way to use the reverse function in the winter.
How do I know if my fan is on backwards?
If you are unsure if your fan is turning the correct direction, stand directly under the fan and look up. If the fan is moving counterclockwise and you feel a rush of air, it’s in the correct setting for summer. If you don’t feel much air movement, it’s possible that the fan is spinning in the wrong direction.
How do you tell if a compressor is running backwards?
Look for the following signs to verify reverse rotation:
- Discharge and suction pressures do not change.
- Noisy operation (note: noise at shut down is a sound issue only; it will not cause damage)
- Current draw is substantially reduced compared to tabulated values.
Why is my compressor running backwards?
There is a slight chance a scroll compressor could start in reverse rotation. The rotor must have a certain amount of rotational speed in the reverse direction before power is applied. This can occur during a momentary loss of power to the compressor motor (e.g. power flickers during thunderstorms).
What is CCW direction?
Counterclockwise(CCW) refers to rotation in the opposite direction as that of the hands on a clock. The direction in which the clock hands rotate is called CW (clockwise).
