Question about Mitsubishi MSH09TW Air Conditioner

The squirl-cage fan (MSZ-A15NA) clogs up with mold once a year, which drastically deminishes airflow. I have had the dealer technician come out and disassemble enough of the unit to gain access to the fan blades. Using pipe cleaners and other methods, and over 2 hours for each cleaning, the majority of the build-up gets removed. BTW, due to the location of the wall unit next to an imovable object, dissassembly and removall of the squirl cage is not an option. And yes, I have found and stopped the source of the mold. I just tried slowly spraying about a pint of white viniger into the running fan's inlet to try to clean things without dissasembly. While I'm letting the last spraying of viniger soak into the stopped fan, I thought I'd see if there is anyone who has a better sollution. Any and all suggestions will be greatly appreciated. PS - the viniger treatment didn't get it.

First of all, I found my own solution. Secondly, the solution provided was not applicable to the problem.

Instead of spraying vinegar, i would say spray wd-40 spray.That will keep the fan and its internal assembly clean and not let the fan movement get tight and rusted.It will not allow the parts to get tight and rusted.-------- But once you spray wd-40, you have to let it remain there for 30 minutes to 1 hour, then turn the unit on .The wd-40 spray takes time to show its effect.--------- The wd-40 spray is easily available at local walmart and homedepot stores or at appliance parts repairs store.---------- This will help.Thanks.Helpmech.

When we turn on one of the air conditioners, a musty odor comes out of the blower. All the other air conditioners in the house are normal

Some times water will not drain out right need to clean the drain pan, blower wheel will also catch dirt and build up mold. The front cover should come off easy, there should be three screws on the bottom and it should pop right off after that, exposing the pan and blower wheel . Clean as needed.

I want to clean the squirl cage fan on my Carrier handler. It's 12 years old and never really been cleaned. What is the best cleaning procedure to maximize its efficiency.

The best way to really clean the squirrel cage is to remove the entire indoor blower motor housing assembly out of the furnace then remove the squirrel cage from the motor shaft and pressure wash the squirrel cage. Make sure you don't use to much water pressure as you might knock off any balancing weights that may be attached to the one or more of the vanes. Make sure the cage is completely dry before you re-install it back on the motor shaft.

Whwn i turn the heat all the way up loud clicking noise if turned lower noise stops what could this be notfan

I think your talking about the heater fan? If you hear more noise as you increase the blower speed, there is something in the squirl cage or a problem with the blower motor itself. Leaves, paper or something lite on the pass side floor, it will get sucked into the recirculation duct,causing a noise.Remove the blower motor and clean out any debris, and inspect the squirl cage and turn the motor by hand to see if you hear any noise

okay, you need to check your ventillation, make sure it is not clogged, if not then change your coils, there are 2 black coils at the burner, one has 2 terminals and the other one has 3.

Water on the squiral cage side I don't know where its coming from

I don't know exactly what you mean by getting water on the dry side of the compartment. In any event, as you will see, there are very few sites that are dedicated to the maintenance and repair of evaporative coolers--you, in fact, submitted this problem of yours under the Air Conditioner section because there is no Evaporative Cooler section.

Having said this, I offer you two things: 1) a site that has a section dedicated to evaporative coolers, which took me a long time to find for my own problems:

http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Coolers.htm

and 2) the general idea that if you have water where it is not supposed to be, it likely is because there is a hole---obviously caused by rust--that allowed such water to get penetrated through. See more on rust holes of coolers here:
http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Coolers_Cooler_Has_Holes.htm

This should help get you on your way.

Good luck!
