Question about Fujitsu 18C1 Air Conditioner

1 Answer

Condensate overflows frequently.

I don't know how to access to clean out the drain. I just blow it out from the drain tube, but that doesn't last. I took the cover off, but that didn't provide the access to clean it out. The manual I have doesn't help.

Your drain tube is usally under the coila and is sort of hard to access it anyway. There are two things you need to do 1st take a wet/dry vac and hold the hose on the drain tube which will **** out any type of blockage there is (mostly algae) 2nd you need to get some treatment tabs from an a/c supply shop that all you do is place one of these tablets in the drain pan and it will prevent the buildup of algae therefore preventing your clogging issue. Good Luck

If Mr. Goodwin does not know for sure the Maytag Model numbers how do we know his solution to the bottom of the freezer being covered with ice is correct. I also have a Maytag Mode#MF12665XEM7, Seria


Hello Molly;

I am sorry you are so frustrated.

Having done what you have described is only going to last until you cycle through the next automatic defrost. Your freezer section goes through a defrost cycle every 8-10 hours, where your unit shuts down for 20-30 minutes and your defrost heater turns. Everything will shut down except for the light bulbs.

You have a frozen drain and the condensate has no where to go except on the bottom of your freezer. The back wall of your freezer needs to be removed, where you can attach a 12 gauge wire to the defrost heater and run it into your drain hole. The defrost heater is about 4" away from your condensate drain and can not clear the ice.

I see you have a bottom freezer. They are a service technicians night mere when it comes to pulling the back wall off to access components.

Since you have a bottom freezer and the difficulty involved to do a permanent fix as described above, you only have two options.

1.) If I was still working for Sears Home Services and I came to your home, I would have to charge you at least $240.00 for the job.

2.) Or, you can turn you unit off for 24 hours with the doors open and let the ice in your condensate pan and drain melt. This may last for a year or several years, it is hard to say.

Why do drains freeze? Once I found a kernel of corn in the drain. It starts with one droplet of condensate clinging to the inside of the drain and then another and so on.

Tips to help prevent your drain from freezing:
1.) Unplug your unit. Pull it out so you can access and remove the back lower panel. Look for any leveling jack screws on each side of the front end. Turn counterclockwise to lower until your unit is free to move. You may have locking wheels.

2.) If you have a small rubber grommet on the end of your drain tube, throw it away. The original purpose was to prevent air from going up the drain tube. What it actually does is inhibits draining and creates a air pocket.

3.) If up have a 'S' shaped drain tube replace it with a straight tube. The 'S' tube also inhibits free draining. They are available at your local appliance store. Do not through the 'S' shape away. On some units they are required to prevent one door from popping open when you close another, but not necessary on all units.

So, Molly, will you give me a helpful on this one?

My portable windchaser airconditioner pacr9 sounds like theres some water in the top area and is blowing out some water from the front vent ? any reason why ?


This usually happens when the unit is dirty. The filter provided is pretty worthless and dirt and dust build up inside the unit badly. This causes the unit to operate inefficiently. Condensate builds up on the evaporator and freezes. When it defrosts water drains through the unit to the bottom, whats left is a muddy sludge and a clogged evaporator. The condinsate will then overflow into the fan area. Normally the condensate will be exhausted through the warm air vent in the back of the unit.

To fix this, you need to unplug the unit, then remove the entire back cover. Not just the small cover on the upper portion. Once removed you can then have access to the entire evaporater and condenser. Clean these thoroughly with a vacuum and toothbrush if necessary, Let the unit defrost if the evap was clogged with ice. Drain the unit thoroughly with the tube at the bottom of unit. I lay a thick towel on the floor and let it drain into the towel. Clean the fresh air intake area on the upper rear thoroughly, I used windex, then flushed with water, which ten drained to the bottom of the unit, and out onto my towel. Reassemble and run in fan mode for an hour, allowing the condensate that overflowed into the fan area to evaporate. You should be all set.

This maintenance procedure should be performed yearly or as necessary on these units.

Clean the drain holes ?


Get a vacuum cleaner and **** any dirt from the end of the drain hose. If you can access under the evaporator from the side, clean the base tray as well.

Unit in basement leaking around bottom


The drain line coming from the internal drain pan to the pump is clogged, causing overflow of the internal pan. That means the water never reaches the pump, and is simply overflowing into the bottom of the unit/duct.

The drain line and pan need to be cleaned and cleared.

A shop vac is a wonderful tool for such a job.

Your air conditioner evaporator condensate drain is blocked.
The condensate draintube should carry this water out through the floorpan to the ground.
Look for a kinked or blocked drain tube from under the A/C evap housing.

Leaking water in my closest where the handler is


The condensate drain line may be blocked with sludge. Usually it can be unplugged by blowing compressed air backwards from the end of the line. If the line drains into a condensate pump, the pump could be bad and overflowing.
