I have put 3 boards in from Repair Clinic 2 did nothing 1worked for 2 miniutes they refunded my money my original board runs except for defrost. Does this sound like the replacement boards were defective, seems like the original would fail if it were something else.
Answer Hello Tom,
This could have been a poor connection as well as a bad board. Electronic controls are touchy items that can be affected by many factors. It is possible to destroy the programming on a new board by simply touching a terminal. Static electricity can be strong enough to change the digital information stored on the "chip", (integrated circuit). This being said, the issue cannot be diagnosed through hindsight. As far as the defrost issue goes, you may have a bad defrost thermostat 5303918214, which is common on these units. There could also be a poor connection, a burned out defrost heater 242044113, or the new board 5303918525 could have an issue.
