Error Code F34 But Sail Switch Is OK
Model Number: C304 Brand:
5 - 10 years
Have an early 2000 Thermodor C302U that displays error code F34. Sail switch is functioning and has been tested for continuity. Connection at display board was inspected, in addition the terminals were jumped out to simulate closure of the sail switch. All has still resulted in a F34 error code.
It is significant to note that this error code has occurred after replacement of the relay board which was replaced due to failure of the circuiting/pins at two harnesses located near the transformer.
Our question on this subject centers on how the display board interfaces with the relay board and should we be looking for a defect in the display board or possibly a problem with the new relay board.
