How do I remove cooling grille on my WTE86300BY/02? I don't want to break it. I regularly clean air cooler with warm water, taking it out through the maintenance flap. But I can see that inside the cooling grille (just right to the maintenance flap), dust is building up and went is filled with it.

things you'll need: Turn off gas supply. remove
Gloves grills grates.clean the grill
grill brush grates scrub them with grill
cleaning rags brush. clean anything
putty knife or bristle brush covering the burners. clean
soap clean the burners, lightly
water brush the burner tubes and
make sure all the gas ports are clean and open.Clean the bottom of the grill and lid. Brush or wipe any debris out of the bottom of the grill. If there is peeling black stuff on the grill lid or bottom ,use a bristle brush or putty knife to scrape off. Clean the grease collection tray with soap and water or replace and disposable trays as needed. Wipe down the outside of the grill with soap and water. put the grill back together .. now your ready to grill,

U need that hose to direct the warm air outside the area to be cooled. If you remove it, the hot exhaust will stay in the room being cooled and negate the cold air being directed into the room.

That is why regular room AC units are mounted on window sill. Cold air in, hot air out.

evaporative coolers use a principle of blowing air though a filter that is water moist
the air passing through the water uses a heat exchange process as the water boils off, the air is cooled and so you get cooler air
very efficient in places where the humidity is under 80% but over that the water doesn't evaporate all that readily and so the effectiveness is reduced
basically the hotter the day and the lower the humidity the more efficient they are.
Cheap --yes as it only runs a small motor for the fan and an even smaller motor for the water pump, but you will need a regular water supply some units have a small tank which needs regular filling and others can be connected to the home water supply
it is not an air conditioner , simply an air cooler.

I just had a problem like that on my 96 passat tdi , there is a door on the pasages where the air goes through the heater core and a/c radiator thinghy which gives out the cold,and that litle door which redirects the air between the heather and cooler ,is mad of a sheet metal with big holes on it and covered whit a dense sponge and that sponge is breaking of trough out the years so the air passes through dose holes therefore the air passes by the heather core and the cooler part at the same time so when the car warms up no more cooling because it also heats it up .

you have to take out the shifter cover ,one piece with hand brake ,and front of it there is a air redirecting duct to the foot ,if you remove that you will see that door ,and glue some thing on it ,it is dificult ,it is hard to accces but posible

you can also check or maybe you remember if tini sponge pieces been blown out through the vent grills ,good luck ,

The condenser coils dissipate heat. If dust and debris accumulate around the coils, your refrigerator may not be able to cool properly, it may run continuously or it may stop completely as a result of an overheated compressor.

Floor Level Coils
You should clean floor level coils at least twice a year. Unplug the refrigerator before cleaning. Vacuum or brush the coils.
Remove the grill from the front of the refrigerator and use a vacuum with a wand attachment to remove any dust and debris. The grill should snap off and on. Pull firmly toward you and possibly upward to remove the grill. If it does not come off with a modest effort, check for screws or retaining clips that may hold it in place.



Rear-Mounted Coils You should clean rear-mounted coils once a year. Unplug the refrigerator before cleaning. Refrigerators are heavy, never tip one forward or backward. Never attempt to move a refrigerator without an assistant.

Vacuum or brush the coils. If coils have a filmy build-up, use warm soapy water to clean them. Take care not to spill or drip water onto the components of the refrigerator.

Ice container, measuring containers, and baskets: Dishwasher-safe (top rack only).

Measuring containers should be placed in a dishwasher basket. Or wash in warm water
using mild liquid soap. Rinse with clear water.

Bottle Warmer unit and removable cooler: Always turn OFF and unplug before cleaning.
Wipe surface of unit as well as inside of cooler and cooler lid, and inside of warming
chamber with a damp cloth or sponge using mild liquid soap. Wipe with clear water. Air dry.
Do not immerse in water. Do not use scouring pads, solvents, or abrasive cleaners, as
these could damage the unit.

Warming chamber (optional): Mineral deposits (usually white in color) may form on the
inner surfaces of the warming chamber and can cause damage to the unit. To remove them:
1. Unplug the unit.
2. Remove the basket, and wash separately as indicated above.
3. Pour 2 oz. vinegar into the warming chamber and let it stand for an hour or two (longer if
necessary).
4. Pour out the vinegar and rinse the chamber two or three times by pouring in, then
emptying out, 3 or 4 oz. of plain tap water. Do not immerse the Bottle Warmer in water.
Wipe dry or air dry.

WARINING
Do not remove the cylinder block drain plugs or loosen the radiator drain **** with the system hot and under pressure. Serious burns from coolant can occur.

WARNING When removing the radiator or A/C condenser for any reason, note the location of all radiator- to-body and radiator-to-A/C condenser rubber air seals. These are used at the top, bottom and sides of the radiator and A/C condenser. To prevent overheating, these seals must be installed to their original positions.

Removal & Installation:

1. Disconnect battery negative cable.
2. Remove radiator pressure cap.
3. For access to radiator draincock, remove radiator grill mounting screws and remove grill.
4. Attach one end of a 24 inch long x 1 / 4 inch ID hose to the radiator petcock Put the other end into a clean container. Open petcock and drain radiator.
5. Detach power steering fluid reservoir from fan shroud and lay aside.
6. Disconnect electric cooling fan electrical connector, if equipped
7. Disconnect CRS hose from radiator filler neck and remove from shroud retaining loops.
8. Remove the four (4) viscous fan/drive assembly nuts from the water pump pulley and remove fan/drive assy.
9. Remove the four (4) fan shroud to core support mounting screws.
10. Remove the electric fan (if equipped) and shroud assembly from the vehicle
11. Remove radiator upper crossmember.
12. If equipped with air conditioning, separate radiator from condenser by removing condenser-to-radiator mounting brackets.
13. Disconnect upper and lower radiator hoses.
14. If equipped, disconnect and plug automatic transmission fluid cooler lines. Quick Connect Fitting Release Tool 6935 may be needed. If equipped with remote transmission cooler, remove line to cooler from bracket at bottom of radiator
15. Lift radiator straight up and out of engine compartment taking care not to damage fins.
16. If radiator is to be replaced, be sure to remove and transfer any components not included with replacement radiator.

To install:

1. The radiator is supplied with two alignment dowels. They are located on the bottom tank and fit into rubber grommets in the radiator lower crossmember.
2. Lower radiator into engine compartment. Position alignment dowels into rubber grommets in radiator lower crossmember.
3. If equipped with air conditioning, attach condenser to radiator with mounting brackets
4. Install radiator upper crossmember and four mounting bolts.
5. Install radiator upper crossmember-to-isolator nuts. Tighten nuts to 86 inch lbs. (10 Nm) torque. If isolator-to-radiator nuts had been removed, tighten them to 47 inch lbs. (5 Nm).
6. Connect radiator upper and lower hoses.
7. If equipped, connect automatic transmission fluid cooler lines. If equipped with remote cooler, attach cooler line to bracket at bottom of radiator.
8. Install electric fan (if equipped) and shroud assembly. Insert alignment tabs at bottom of fan shroud into slots in bracket at bottom of radiator. Tighten mounting bolts to 31 inch lbs. (3 Nm).

I really hope helped with this (remember rated and comment this help) Good luck.

Make sure that you have enough air flow around the unit and that the grill on the bottom is clean and free of dust/pet hair ect..also take into consideration of the location of the unit... make sure it is not next to a heated appliance like a dishwasher or range. and remember that it is not a frig it is a wine cooler so it will not get really cold.... if it has a glass front make sure it is not sitting in direct sunlight for extend periods of time as this will cause the unit to run excessively. I hope this helps.. I hate warm wine..

I take it this is a window Unit , the water is coming in the room because the Unit has to be pitched about 1/2 into the back ( outside ) or the drain line is clogged ( dirt) stopping water from flowing to condenser ( that cools the coil)
The water is condensation from warm air hitting the cold coil .

The fan should blow air into the heat sink. The warm air exits the heat sink at both ends. (It might work the other way, haven't tried it.)

When you have ice in your cooler, you know the thermo-electric element is working well--it's below freezing!

Ice builds up because there is water in the cooler. For example, in humid weather, you open the cooler, some humid air gets in, and the cooler temperature condenses the water. You have to empty this water, either by tipping the cooler, or using a sponge.

You can easily defrost the cooler by unplugging it for an hour or so. You know it's time to defrost when you hear the fan blades making a racket because they're hitting something--a thick buildup of ice.
