ACM18 Whirlpool Air Conditioner - Instructions

had to remove outer cover, then the foam parts covering the fan cage and then remove the five screws that hold the fan/motor unit in the base, after that I cut the wires at the controls so I could match the wire colors up with the new motor, had to loosen the clamps that hold the fans on the shaft at both ends and slide the fans off,when ... Read more the new motor came I put the unit back together in reverse order it came apart, unpluged old wires one at a time and pluged new wire of same color in its place, all left to do was put outer cover back on and less than two hours had it back in my window feeling the cool air.

Took out old filter and replaced it with the new filter

Replaced the temp control and sensor. Controls on this unit are easy to get to and electrical connections were slide ons

Part came quickly, was the right part and went in quickly. Only had to drill out 3 rivets anre reasemble with sheet metal screws.

Just removed the old filter and replaced. Slid right in, no tools required.

Well - first I thought the problem was the capacitor, as that will cause hard starts, especially on an air conditioner (I am no HVAC man, but researched this to find out). Pulled the capcitor (BE CAREFUL - discharge first - It CAN kill you if you don't!). Tested it and found it fine (again - to test - research on the net - VERY easy w/ ... Read more a standard Ohm meter).

So - after investigating a few other possibilities, I sat and listened to the thing run and realized it was cycling too fast (trying to kick the compressor on too close to shutting it off, hence the built up pressure was still too high to kick the compressor on easily. Figured maybe the thermostat was causing this (kicking the compressor on before it was "rested").

I was correct. It solved the problem.

To change the thermostat took like 5 minutes.

BTW - CLEAN YOUR COILS - I'M SURPRISED MY WAS EVEN RUNNING! THE COILS WERE FULL OF JUNK. If your coils are dirty the thing is will not run well and will cost you a lot of money to make your room / house cool!

Hope this helps somebody!

Removed back cover, and installed the water valve. Removed the water supply tube cover and installed the supply tube. Opened freezer and removed the electrical cover, removed the knockouts and pulled line out. Hooked up ice maker and installed it to wall. Turned water on and waited a couple hours, it is making ice. Installing the ice ... Read more maker was easy. Running water line to it........well that is another story. LOL.

even I can replace a control knob....

Unplugged unit.
Pulled front cover and removed switch knobs.
Pulled switch plate off and replaced thermostat switch and temperature sensor bulb assembly.
Reassembled and plugged in.
Unit works normal.

Removed the back - Saw the broken clips on the base of the dryer (the wires to the motor were pulling out because the motor was slipping).

Guessed that the parts were motor clips (no pix in the web site!)

Got the parts in post - they were identical except needed some rubber grips inside to hold tight (Used pieces of ... Read more bike tire inner tube cut to fit for this.) Attached clips. Works fine!!

Identified the problem as broken exhaust fan and ordered part. Disassembled unit, installed fan however during the cleaning process the blower fan was broken but would still work. Tested the unit for functionality, fan motor failed. Ordered the blower fan and motor. Finished the cleaning installed the motor and two fans. Assembled t ... Read more he unit and returned to the thru the wall mount. Unit has been working great. Even though the process was an ordeal saved $400.00+ on doing the repair myself. I would not recommend you attempt this kind of repair unless you have mechanical skills. Fins are very sensitive and in cases have to be combed.

pulled unit out far enough to take screws out of box holding thr thermostst and replaced it!
