2010 Buick Lucerne. AC does not work. Had it serviced. Blowers work. Full of freon. Fuse revealed it was blown. Replaced and blew again. Service tech tried 4-5 times and fuse blew each time.


not much of a service tech that keeps replacing fuses without fixing the fault
It suggests that the ac compressor clutch coil needs replacing

Is there a separate fuse for the power locks


There are actually four fuses that are involved with the power door lock circuits on your 1996 Buick LeSabre. There is also an electronic control module, switches, and several other components that can keep your door locks from working. Replacing a blown fuse will only result in another blown fuse if the reason that the fuse blew is not properly diagnosed and repaired.

Sony 6060F blown fuse


hello!
there is a standard procedure for proper replacement of blown fuse: CRT TVs: unplug degaussing coil, replace blown fuse with 2amp fuse and turn on the set. If it works, reconnect degaussing coil, replace the fuse with correct value(5-8) amp, depends on model(see fuse note next to holder). Enjoy the show! If in a process of replacing the blown fuse with 2amp w/o degaussing coil it blows again, forget about the next step. Set need repair. It could be an easy one, replacing 1 or 2 shorted diodes or bridge rectifier, but could be real piece of work if the power supply got "fried". If your knowledge won't go further, than fuse replacement, I'd recommend local TV repair shop.
good luck,
Alex.

You have defective power supply board, Are you OK to strip it down and inspect the board? You will either have to replace the board or have it replaced/repaired professionally.
I hope I have been of help

Maytag washer model LAT9306AAE won't come on - replaced blown fuse in machine & it blew again right away.


Fuses are there to protect from overheating and further damage to the appliance and/or wiring. A blown fuse is seldom ever the root cause of a problem... It is a symptom of a short or overload somewhere else in the circuit.

Check wiring to be sure there are no bare wires showing or shorting out against each other or the frame of the machine. Check that drive and pump motors turn freely (with power cord unplugged).

Your problem is NOT the fuse alone. Replacing it without correcting the root cause will result in yet another blown fuse.

power surges generally damage diodes and capacitors causing the fuse to blow, any reputable tv shop can repair for a fraction of replacing this set.

Full sound not working


I had the same problem and also traced it back to two of the four 7-amp fuses were blown. I replaced the fuses, but they immediately blew again. I used higher capacity fuses (10 amp) to see how bad the problem was and those blew. Testing the problem a third time with the speakers disconnected yielded the same results.
There's an internal short in the system.
The solution? Don't buy RCA again.
