Hi Charity, F1 is a communication fault, I hope this helps......... CHEERS..
1?Check whether the connection of the outdoor unit and indoor unit is one to one, otherwise connect the L, N and communication line of the indoor unit and outdoor unit one to one.
2?Measure whether the voltage between the zero line and the communication line is 18V-30AC half-wave signal, check whether the communication circuit on the indoor and outdoor electric control board has been damaged, otherwise replace it.
3?Check whether the LED on the outdoor power board has been on, otherwise replace the electric control board.
4?Check whether the unit is abnormal caused by the external interference, if it is, then find the interfering source, and removes it.

Signal transmission error (between indoor and outdoor units) which means a faulty indoor or (more likely) faulty outdoor controller board. Call a tech.

Possibly a bad control board in the outdoor unit. Pull the disconnect outside to stop machine, wait 10 seconds and out back in. White mist was likely frost built up on indoor coil due to condenser running without the fan.

Hi; need more info. If You are talking about a indoor unit curcuit board and this is a clearish white plug then it is for a heat strip assembly. I really dont understand your question. Has something come unplugged, is the unit working?...

i dont really understand, but if it a residential split and you have water in the emergancy pan underneath the indoor unit there is a float switch in that pan that is open not letting the unit come on it is there to prevent water from leaking throgh the ceiling.
drain that pan and unit should come on however something is wrong. when is the last time yuo changed the filter 9 times out of ten that is the problem if filter is changed and indoor motor not running that will cause unit tice up causing leak, third the which is unl,ikely you have a leak. if i can help you anymore please let me know

These units have circuit boards inside that have lights on them. These lights come on and tell you what the problem is. I have had 4 units do the same thing that yours is doing. The result has been that the compressor has gone bad. You have to get access to the control board to see the lights. There will either be one inside the inside unit or one inside the outside unit depending on exact manufacturer date.
Good luck and hope this helps.
