I have a air conditioning Unit Midea Model KFR-23IW/XIC-M the unit works heats and cools OK but the internal unit shows ERROR F2, the company who supplied the unit to me advise me its a problem with the external outdoor coil sensor. Although I purchased the unit from them, they are unable to supply this part.

I have checked the connections to this sensor and the plug and circuit board look OK, can anyone advise where I can obtain this sensor to get rid of this error, I don't want to replace the unit because of a small sensor
