I have a panasonic inverter air con. Model CU-E18LKR. it's not cooling properly. Seems to be blowing cold air out on th outside rather than inside.need instructions on troubleshooting


This is a reverse cycle (heating and cooling) model. It sounds like you have it in heating mode. Check the Panasonic website for an owners manual.

IT WORKS BUT AT THE CYCLE END SUPPLY COLD AIR IS IT NORMAL?


Most air cons now have temperature sensors all over the machine. When it reaches temp on heat cycle, the machine usually shuts down both indoor and outdoor units but the indoor unit will keep running for a few minutes with the fan on only to cool the indoor unit down. This prevents the unit reading the wrong temperature. It stops the sensor(s) reading the heat from the indoor unit rather than the heat in the air in the room.

My Honeywell thermostat isnt keeping my house cool even though the temp is set to 69. Currently 90 degrees in here


Its probably not the thermostat. The air conditioner may be stuck on heating mode. If its a reverse cycle, the reversing valve may be jammed so even when the thermostat is calling for cold air, it stays on heat. If the machine is on heating mode, it should be blowing cold air out of the outdoor unit of the air con. If its on cooling mode, the outdoor should be blowing hot air.

Hi, The air con in my 2003 Audi A6 1.9 tdi 130 is blowing warm air the air con rad is fully gassed and all fuses are ok . Thanks in advance for any advice on how to fix


The only other thing then would be if the compressor is turning, engaging, and the cooling fan working properly. You should either be able to see the compressor clutch engage, as the switch is energized, or at least hear it click loudly when the switch is energized. If it is not, then there are sensors for the low pressure/high pressure line to tell the compressor when to function, that also have to be checked.

As the engine runs with the compressor turning, one line should be hot/warm, the othe,r (larger diameter hose) should be cool/cold, if the system is working properly.

If the compressor is turning when you have the A/C turned on, then see if the cooling fan is running as well. It must run to remove the heat and cause the process to function properly.

Good luck!

Omni air con blows air but there is no heating or cooling. what is wrong and how can it be fixed?


I had exactly the same problem (it survived for 5 years) and I am sorry to say, Omni airconditoning no longer exits so you can't buy parts. You could find a good technician who maybe be to help you. The compressor had burnt out on mine and they were unable to repair it and also something to do with a burnt switch in the internal unit too. I had to replace my aircon completely so I now have a new Mitsubishi 19 DBL - very quiet. :) Lynne

My LS-H186 VML 1Metal Art Cool 12000 BTU Air Con does not heat up


You should also check the outside unit to make sure the coil is not clogged with dirt or grass clippings and the fan is working. The reversing valve that switches it from cool to heat could also be a problem. If it isn't shifting it will not switch between heat and cool.

Fujitsu Reverse air con not blowing heat anymore


Reverse setting could need checking here sliding valve could have siezed. you would need a service Technition. your default setting is working fine so it needs to be checked on heating mode function.

My head unit keeps freezing up? never used cooling till now, but have used it for heating? why is this happening?


Heya,
Sounds like you have a gas leak on your air con.
When the air con runs on heating it runs at a much higher pressure and has more chance of it leaking. I suggest you get a refrigeration tech out to test it out.
There are other things that it could be but none of them are fixable for someone that dosent have a refrigeration license. Sorry but hope it helps
