Dometic A/C controller board
I searched forums for some info, but no luck, so here goes.
Our '95 Land Yacht 30 foot had a leak at front roof A/C in January.
Water collected in the plastic air vent cover where the control board resides.
A/C is Dometic model 620215.321.
Controller board assy number 3105256.004.
Corrosion occurred causing loss of two pcb components.
Board is obsolete, replacement from Dometic is a new set of boards plus accessories for $800.
Board looks ok after good cleaning (alcohol and small brush).
I may be able to repair if I can identify values/ratings of the two parts.
Picture of lower right corner shows F1 and C4 missing.
I apologize for fuzzy pics, poor camera.
Believe F1 is axial lead fuse and C4 (capacitor) most likely 0.01 or 0.1uF probably to control back emf when relay switches states.
I can guess at both, but if someone has a clear photo of the pcb showing that area or a schematic of the pcb assy with values, that would be much better.
Dometic cannot supply schematic or values for the pcb (couple hours phone time to find that out).
They were able to provide wiring diagrams for connections between the controller board, motor and compressor, but I need the pcb detail schematic diagram.
Thanks in advance for any advice.
