Fan and compressor run but unit will not control temp. Compressor cycles off too soon, but after awhile will come back on.
You will want to check to make sure that the sensors are within specs. The resistance values for the thermistors are Room sensor 424200 at 32 degrees, 299800 ohms at 50 degrees, 178400 ohms at 70 degrees and 109800 at 90 degrees. For the indoor coil sensor the values should be 658900 at 32 degrees, 399800 at 50 degrees, 237900 at 70 degrees and 146500 at 90 degrees. If out of range then would need to replace the sensors. These sensors come as part of the main PCB WJ26X10241.
