What is fedders AC error code 7f

i would try to oil bearings on motor. that failing replace run capacitor. motor must be getting hot.

Get a old fashioned cork.

Indoor coil temp defective. Replace it.

Disconnect power to the unit and reconnect. If "stop" is still on the display you will probably need a qualified technician to trouble shoot. The best mode is the snowflake (cooling). The rain drop is dehumidification which can cause condesation on unit.

If this is a digital read out system,the circuit board has gone out in the unit behind the control panel.

sounds like your switch is bad still allows power to compressor when it shuts down the blower,,.....

no blower !!! or heating element is bad or switch try putting the fan on only if it works than it is probaly the switch not letting the blower on only heat

u have to be more specific. is it gas or electric. If electric check breaker first. Gas check thermocouple

I would try to start the unit with only the fan running at first. If it stays running then cycle on the compressor and see how it does. If the unit does not operate when compressor is turne on then we have to dig deeper into that.

Can you descibe where the unit is located and what climate you are in? Thanks
