I have a refrigerator brand Fagor mod. VT-12A type JC-33C, to fail once the power and return (has voltage regulator and delay of ignition), began to emit a signal and to the time it turned off and it worked normal, this was repeated several times but the last one already does not turn on the display and does not cool, only a sound similar to a clock is heard when the door is open. fuse continuity is measured, but no power is supplied to the external fan connector. The card looks in excellent condition and is a fairly new computer thank you and see you soon.
