Air Conditioner Blower NE1639

1. Remove 7 screws on rear cover. Use a pocket knife or similar slim tool to pop out the screw covers in the center and top of the unit. Remove back cover.
2. Remove two screws at top of front cover. Pop the cover off the middle and bottom side edge retainers.
3. Remove the white cover over the electronic control board using a small common blade screw driver to help release the pop together catches.
4. Unplug the white ribbon cable that goes to front cover controls. This allows the front cover to be completely separated from the unit. Remove the 2 wire black sensor connector next to the one just removed.
5. Remove the 4 screws retaining the upper blower assembly to allow access to the screw located below the fan motor.
6. Now you can move forward to replace the squirrel cage. Remove the rear exhaust grate.
remove the 4 screws holding the blower to the bottom cabinet and the assembly together.
7. Locate and remove the screws holding the top separation plate from the blower and lower area to allow the blower enough clearance to be removed out of the separate the half with the motor and loosen the screw retaining blower wheel. Note the distance the shaft protrudes past blower hub before removing. You will need to put the new blower wheel into the same spot so that it does not rub.
8. Replace the wheel and remove and broken pieces from the enclosure. Be sure to check for fan blades that may have fallen to the bottom and fallen between the two halves.
9. Reverse the steps until the lower blower is back in position and the halves are tightened together. Through the exhaust port move the wheel gently to test for free motion.
10. Continue assembly until you get to the point where the cable are connected. At this point you can test the unit. If the unit comes on with the exhaust blower working during the cool cycle you should be done and ok to replace the covers. If the unit starts cooling down and does not have exhaust blower operation and it shuts off cooling in about a minute then the blower motor is defective. This can be caused by the motor burning out an internal 2 amp 115 degree over temp protector in the coil winding. This is an expert repair to replace or a hard repair because you have to go through the same steps to replace the fan motor or risk breaking a fan blade to short cutting the blower wheel removal.
11. Mine was both and is now assembled and operating normally. My unit was a PACN120E

I followed directions on the web site which were very helpful. If you are good with following directions and basic tools (screwdrivers) you can complete this. Remember to note where all of the screws came from and their sizes. The part was correct and easy to replace once you get to it .... which is the hard part.

1. Removed front and back of portable AC unit, marking electrical hook ups.
2. Disconnected framing from base, and loosened compressor bolts and any other items to allow blower case to be opened and blower to be removed and replaced.

Very complicated disassembly of the air conditioner to replace the blower fan.

Followed instructions noted on previous completed repair for this replacement except used a 5/16" box gear wrench to tighten set screw on blower wheel to fan motor shaft, not enough room to use a socket and ratchet to properly tighten set screw.

Removed screws holding outer cabinet halves. Unclipped cabinet halves and set rear half aside.
Carefully removed front cabinet half without straining control panel cable. Removed cover on internal circuit board. Disconnected control panel cable, air temperature cable and motor-capacitor leads. Removed screws holding evaporator coil. Removed screws holding evaporator fan housing and set aside. Removed screws holding evaporator pan. Lifted evaporator pan on one side. Removed screws holding blower fan grill and removed grill. Removed screws holding together halves of condenser blower housing. Lifted half out half of housing containing motor and blower wheel. Using adjustable wrench, loosened set screw holding blower wheel. Discarded any pieces of blower wheel remaining in blower housing. Installed new blower wheel on motor shaft, lining up set screw on flat of motor shaft. Tightened blower set screw securely. Replaced blower housing in position temporarily and checked alignment of blower wheel for free rotation. Installed screws in blower housing. Replaced blower fan grill and installed screws. Installed screws in evaporator pan. Replaced evaporator fan housing and installed screws. Installed screws holding evaporator coil. Replaced leads to motor-capacitor and cables to control panel and air temperature cable. Replaced cover on internal circuit board. Using shop-vac, removed accumulated dust and lint on condenser coils. Replaced both cabinet halves, aligning the clips and installing the screws. Cleaned rear cabinet air filter. Installed plug in outlet. Performed test run of AC, setting desired temperature low enough to engage compressor and condenser blower. Checked for smooth running of blower wheel. Checked for cold air at front grill. Checked for high-volume air flow at rear exhaust.

Watched several YouTube videos on blower motor repair in similar ac units, and then took my unit apart. I kept items in order as to not lose any screws because you'll end up with about 20 of them. Most are the same size, but mark extraction areas. Removing the original blower wheel is difficult, and I wouldn't recommend prying while still attached to unit. Most casings on the unit are plastic and will probably be damaged very easily. I was able to wedge a long screw driver between wheel and metal base it attaches to. Good Luck
