Purchased the above dryer at a charity sale. Two issues have arisen. There was an error code of F-25 (which is the inlet thermistor open or shorted code) initially in memory. My meter did not confirm this. There was continuity in the cable on P4-1 & P4-2 from the ECU to the inlet thermistor and the ohm reading for the thermistor was within range for the ambient I took the reading at. (tech sheet says 49-51k ohms at 77F). During a test load I opened the door to add a garment and the control begin to flash F-1 which is code for Primary Control Failure. I cancelled the cycle, unplugged the dryer, then replugged the dryer, the error cleared and the machine went back to work. So, I suppose my question is, are these electronic controls always to be trusted? If the ECU has failed how is it now accepting commands and continuing to run? Or am I over complicating the obvious and should assume the ECU is in the process of failing or is at best suspect? Thanks in advance for your kind attention in this matter.
