HI Duncan, Error Code F42 means the Outdoor unit P.C. B (NOISE FILTER) is faulty or connector ACN2 Enclosed is a link to 2 service manuals that may be helpful you. Good luck, JP https://www.manualslib.com/manual/1155827/Panasonic-Cs-A24bb4p.html#product-CU-A34BBP5 https://www.panasonicproclub.com/uploads/CZ/catalogues/cac/service-manual/CS-F50DB_service%20manual_mac0502037c2.pdf

Temp sensor, bad motor, bad control board…too complex you need help. Your outdoor unit will have a better diagnostic code to hopefully narrow the problem but this requires opening of machine.

possible bad motor also check voltage to motor

thermostat or or thermal cut off. I would take it down and return for another one, do not try fix this yourself. parts will exceed price..

The F95 error code appears on Panasonic inverter air conditioners due to the overheating of the outdoor coil. It is basically, protection against the outdoor high-pressure rise. This problem usually occurs due to issues relating to blockages, a dirty condenser coil, cool mode, or low gas.

Assuming you have a mini split and not a VRF system (although it is possible the error codes are the same),the h11 code typically indicates a communications problem between the indoor and outdoor units. This could be due to loose or broken wiring, a bad connection at either end or possibly a bad communications board in either the indoor or outdoor unit.

It is likely equipped with a temp sensor that only permits the fan to run when the compressor reached a certain temp. If the unit is short cycling then obviously there is a problem. Likely in that sensor. Good Luck. If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_092728000e6acb79

I searched the internet using https://www.google.com The site below is alleged to have the filter for that model: https://encompass.com/model/MSCCWC101MU

This error is: Indoor / Outdoor wrong connection Check that the wiring between the indoor and outdoor have not been crossed over, ie make sure that the same color wire connects the same terminal number on both the indoor and outdoor. After that, check that you are getting full supply voltage to the system. High resistance somewhere in the circuit may not provide sufficient power. Corroded isolator contacts or wire terminals for instance.

H55 error comes from the window that has not properly function to open, you must have off the breaker of the unit then, remove the upper window and check if the motor is not parallel to each both side, then return it and switch the breaker and turn on the unit

Hi Sandra , Error Code F42 means the Outdoor unit P.C.B (NOISE FILTER) is faulty or connector ACN2 Enclosed is a link to 2 service manuals that may be helpful you.

That's indicating that an error has been detected and you need to put the remote into service mode to find out what the error code is. You will have to repair the fault before it will return to normal operation.

14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation. 2 Press the CHECK button on the remote control continuously for 5 seconds. 3 "- -" will be displayed on the remote control display. Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking) 4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed and signal will be transmit to the main unit. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main unit. 6 When the latest abnormality code on the main unit and code transmitted from the remote control are matched, Power LED will light up for 30 seconds and a "beep" sound (continuously for 4 seconds) will be heard. If no codes are matched, Power LED will light up for 0.5 seconds and no sound will be heard. 7 The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5 seconds or operating the unit for 30 seconds. 8 The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.

The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller. Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.
