SOURCE: Unit will not blow cold air after starting up for first time this season

you may need to remove the rear cover to examine what is and is not running. once you remove the back, start up the unit on a workbench. see if the fan is running and the compressor has kicked in. look at the larger or two tubes coming out of the compressor. if it is cooling a small layer of frost or condensation will appear on this " suction" line. if this tubing and the other one are approx the same temperature, then there is a freon leak in the system. Only an EPA certified technician can fill your unit. I am not familiar with that RED button but it mat be a reset of some sort. With the back removed see how it is connected in the wiring circuit. if you have the wiring diagram, please send it to me under my regular email address and I'll walk you through the troubleshooting procedure.

SOURCE: won't cool below 80degrees f

It won't cool below 90. It's worse than a fan. The air is not cool and I can't find the manual. I think I did not install it correctly. Do I have to put ice in that tray? Because that tray is empty. Even after using it for 3 days. I recently found this tube with water in it. I released it and still nothing. The air coming out is hot not cool or cold.

SOURCE: cooling issues (low refridgerant?)

Make sure both the evaporator and condensor coils are clean. After the unit has been off for a couple of hours, start it back up and measure the temperature difference between the air entering into the unit (room air temperature) and the air blowing out of the unit and into your room. You should have approx 20 deg......take this measurement after approx 5 minutes of run time. If the temperature difference less than 15, you may very well have a refrigeration problem. If it is approx 20 degrees, then it could be a dirty coil or an electrical problem.......inspect all of your electrical wires and controls for any signs of overheating.....tighten all connections.

I hope you find this to be very helpful in your diagnosis. :-)

SOURCE: I have ft error on delonghi air conditioner and

Theres a little floatation type device in the removable tank that triggers a switch just above the tank on the unit itself. Just check that that isn't stuck in the "Full Tank" position. I had the same problem and jiggled the switch to make sure it could move and my A/C was back. Hallelujah!!! Hope it works for you...

How to get rid of smell from air conditioner have cleaned filter

Why is there a ***** smell?

I worked extensively on GE Zoneline AZ Air Conditioners and Heat Pumps while a Maintenance Superintendent at a Senior Citizen's Apartment Complex. Not knowing what type of smell to which you are referring, I can assure you that other than "burnt electrical" smells, the only smell that could possibly be produced would be that from within the INDOOR SPACE. Perhaps something has made its way into the INDOOR AIR FILTER? Perhaps that INDOOR AIR FILTER needs to be cleaned. To clean the INDOOR AIR FILTER, simply lift both of the filters from the front cover, take to your clean bath tub. Run EXTREMELY HOT WATER from the back of the filter to the front of the filter. Then, fill your bathtub 1/4 way with EXTREMELY HOT WATER. Add 1 cup of Hydrogen Peroxide and 1 cup of Real Lemon Juice. Set both filters in this solution for 30 minutes; then rinse with clear water. Set filters up to dry for at least 2 hours in the sun or an air breeze. Replace filters into the GE Zoneline.

Also, not knowing how OLD your GE Zoneline system is, the COILS may need to be cleaned. To do this, simply turn OFF your GE Zoneline unit and remove the front COVER of the unit. Next, mix in a spray bottle 4 packets of LEMON flavored KOOL-AID (without SUGAR) and water. Shake well. Spray the INDOOR COILS of your GE Zoneline unit with the entire contents of this mixture. Let set for at least 10 minutes. Then turn your GE Zoneline to the COOL position. The citric acid in the lemon kool-aid will be forced through the coils to continue to remove any dirt, dust, debris and effectively CLEAN those coils. This will also provide you a LEMONLY odor within your room. Simple and cheap.

Enjoy your GE Zoneline unit.

My Kenmore 70088 Air Conditioner have mold

Hello, the coils can be cleaned with coil cleaner that is sold at any heating and cooling store, usually in a aerosol can. The inside of the AC can be cleaned with soap and water. They also sell a cleaner for mold at heating and cooling stores that can be used to get rid of the mold.

The air that comes out of the vent stinks. How do i fix this? Do i need replacement parts? Please help...

No you probably don't need any parts just a thourough cleaning of the water tray and evaperator coils and the air filters. they make a product you can get at hardware stores for cleaning the coils and a mild detergent and water with a little baking soda should clean the rest. you will need to dissasemble the unit for the cleaning so as not to miss anything. Over time water builds up deposits and they can grow algea's and molds that cause these smells. You might however need to replace the filters if yours are not washable or are damaged beyond cleaning. Refer to your manual on the cleaning process.

Strong smell of fuel comming from main outlet vents

The only thing that is vaguely related to fuel (which it's not) in your AC unit is R14 refrigerant gas. Under most circumstances, it's described as a sort of sweet smell. If that's what your smelling, it indicates the it's leaking either fro the compressor or the cooling coils. In which case, the unit will stop cooling pretty quickly.

With that said, it mat be a case of the odor is from another outside source and the unit is picking up the odor and circulating through the AC unit. Also, the air intake filter may need to be removed and cleaned and/or replaced. When you remove the filter, it may give you access to view the condensation pan and the cooling cool and heat disbursement (cooling) fins, which all may need cleaning.

If the condensation pan shows signs of mold or mildew. you can clean it with a bleach and water solution and then rinse it thoroughly. For the coils, use warm water and dish washing detergent. Use a vacuum with a hose and brush attachment to clean the cooling fins.

Check outside an take note of any fuel type odors, that the unit may be picking up.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Strange smell

Have you cleaned the evap coil? Most often smells come from the evap coil. A bleach type product used for cleaning will solve this problem. Thanks

Fujitsu wall mounted air conditioner.

 during Cooling and Dry modes, if the unit is used under conditions of
lower temperature (18C)  the heat-exchanger may freeze, leading to water leakage and other damage.
If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)

Increase Temp to 20 and also run coil dry cycle,

Moldy smell to air

I have a maytag ac unit that kept smelling moldy. We tried spraying with antifungal, only helped for a short time. I took the unit (ac unit slides out of window case) outside and carefully removed screws only to discover the fan was covered in mold!!!! Oh my what a horrible discovery! I washed the fan blades with bleach and water mix. I completely and carefully washed and wiped down the air conditioner careful around the control box. Then I let the unit sit outside in the sun untill completel dry. Good bye mold and fresh clean cool ac!! I will do this each year now that I saw that ugly mold!! That is definetly a health hazard! I would reccommend you either thouroughly clean your unit or pay someone to do it or get a new unit right away!! Don't use that moldy unit another day!! Good Luck!
