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

SOURCE: we have a fujitsu air

Sounds like you have it in heating mode or it is low on charge. In cooling mode, the outside fan should blow hot air not cold.

SOURCE: uotside unit blowing cool air but hot on the inside

It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.

SOURCE: 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.

SOURCE: panasonic air con unit is not blowing cold air out.

This unit is use in motels etc. Check the ouside coil ( conderser) from the inside (discharge fan ) for dirt. Most of these units are floor level . This can cause a unit to short cycle ( cold air is at the floor) .
