Question about Mitsubishi Mr. Slim MXZ30TN Air Conditioner
The unit is 12 years old and while it was supposed to be serviced yearly, the barrel fan has a terrible accummalation of mold which spits out on everything below. The cover comes off but the grill iin front of the fan does not and you cannot get to the fan to clean it. Tke lines prevent removal from the wall for cleaning.
The barrel fan comes out with a few screw removals I know I just did it. It was not really that bad of a job once you know how it comes out. First, remove your front facia piece which clips in at the very top in three places and two screws under the little white covers down below the unit. Once the face piece is removed, look on the left hand side and you will see two screws. Remove the screws and wiggle that end of the evaporator a little and push the evaporator straight up. Once that end of the evaporator comes loose, you should have enough room to remove the drip pan/vane piece. While you are holding onto the drip pan/vane piece detach the drain line from the drip pan/vane piece by lifting up on the little grey piece on the line and pull the drip pan directly outwards which should remove the drip pan from the drain line. Once the drip pan/vane piece is removed, look into the barrel fan on the extreme right hand side and you will see what looks like vane that are missing from the barrel. This is a hole to access the phillips screw that attaches the barrel fan to the motor. Unscrew the screw a few turns and then go back to the left hand side of the unit and pull the barrel fan forward from its mount. You will have to pull the evaporator forward and maybe a little upwards to slide the barrel fan from out the bottom/left hand side area. Take the barrel fan outside spray with bleach, let it sit in the sun for about 10 minutes and then blast all the gunk out with a water hose. Then reverse the order of assembly and then there you have a clean blower fan pushing more air.

I have had to clean mine on a yearly basis. On mine once I have the cover off, I can remove a couple more screws, disconnect the baffle motor and the drain connection and pull the drain pan off to gain access to the barrel fan. The first time I cleaned it with a small bottle brush and bleach water. I scrubbed each fin individually, alot of work! I used a pressure bottle(for the garden with wand) to rinse the fan. Then the next year I used a Shark Steamer to clean and kill the mold, still alot of work but easier then scrubbing. I am going to try rinsing it more often with white vinegar to kill the mold.

I find that spraying it with a lysol stops the mold groth... spray it near the air intake for a bit...

Thanks Thomas. I was amazed how dirty my fan was after less than 3 years. Your directions are spot on. I also had to remove 3 screws on the right to angle the motor a little to pull the fan out. This requires removing the electric control box which is just clipped in at the top and right side. No need to disconnect wires. Just be able to move it out of the way to get to the screws. A little confusing to do the whole job the first time. Next time I think I could do it in 1/3 the time.

You are either going to have to move the lines or clean it where it stands. Us air conditioner guys clean those fans with a garden hose. Very messy!
