Garrison 043-5486-2. Do I even have to bother using the drainage hose or leave the plug in if I only use Unit for air conditioning. Harry.

SOURCE: Is there a drainage plug or hose on the air conditioner? It's leaking.

To increase the efficiency of the air conditioner's cooling to meet US energy requirements, most manufacturers eliminated the traditional drain plug. Instead, they switched to a design that used the extracted moisture from the room to help evaporatively cool the condenser.

To do this, the traditional fan blade was replaced with a 'sling blade' which was a fan blade with a rim or ring around it. The drain plug or drain hole in the bottom of the pan was eliminated and replaced with overflow notches in the back edge. Along with a solid piece drain pan, this provided a pool of water for the edge of the sling blade to dip into and pick up water to 'sling' or spray around the compartment to create evaporative cooling. The overflow notches established the maximum depth of the water pool and are also the lowest place when installed properly.

Although this is more efficient, this has caused 2 problems: increased noise as the water is slung around and water spray from the side air vents.

Persons have drilled holes through the pan or back edge as drains. This is not recommended as it negatively effects the colling ability of the unit and could lead to a voided warranty or premature failure.

Instead, insure that there is adequate pitch with the installation and make sure the overflow notches are kept clear.

If you 'need' a drain hose, my suggestion would be to drill into drain pan's back edge or the rear potions of the sides. The hole should be at the same level as the overflow notches. Once the drain hose is installed, block/cover the overflow notches to redirect the excess water to the drain hose instead.

SOURCE: air conditioning drainage tube blockage

drain tubes are generally on firewall level with bottom of heater box (but on engine side) usually in dumb places that are a pain to get to. They look like a small rubber hose elbow sticking out. Once found, usually you can clear them by just sticking your finger into the end (no screwdrivers or hard objects...you can damage stuff inside there)

SOURCE: Unit is repeatedly freezing up

Almost all dehumidifiers now have automatic defrost, but if you are seeing frost is just one small area, it means there is a refrigerant leak. Check your warranty to see if the sealed system is covered longer than one year. Generally, if it is, most manufacturers will replace the unit (rather than repair it, as the repair is rather expensive compared to the cost of a new unit). If you do not have any sealed system warranty coverage left on it, don't fix it. Buy a new dehumidifier.

On suction line near the compressor

SOURCE: Fan works, air conditioning does not. Try

Without seeing the unit,

1 - the condenser fan (which is in the outdoor unit) could be blown. This would cause the unit to go off on high head pressure.

2 - it could be low on refrigerant, which makes it do nothing but blow room temperature air around. The unit would go off on low pressure

3 - the filter is dirty, blocking the cooling

4 - the compressor could be shorted, or a corroded wire somewhere that feeds the contactor

Mr. Slim Ductless Splits are the best on the market and should only be repaired by a trained technician.

Hope this helps.
