HVAC Blown Control Board Repair

  Todd takes a look at a blown HVAC control board. His sister’s HVAC stopped working and Todd being the nice guy he is decided to have a look to see if it can be fixed. Turns out the control board is controlled by a PIC microcontroller, there was also a blown darlington transistor DIP package. After replacing the transistor package it was determined that the PIC was also defective.
