The circuit board has a 25 Amp slow blow fuse is blown
The circuit board has a 25 Amp slow blow fuse on it and it appears to be broken (Blown). Can that fuse be fixed or can some one tell me how to get the new circuit board because the entire refrigerator is not working.

If your circuit board has a 25 amp fuse that a lot of power, like running the compressor.. you need to have a model and serial number for the unit , there is no generic control board , each manufacture has it's own design
a 6ya Repairman can help you resolve that issue over the phone in a minute or two.

It is common for manufactuers to label the fuses on the circuit board as to their values. If they are not labeled there you can try contacting the manufactuer or looking in your manual. You can tell if they are slow or fast blow by the internal wire, if its thin and straight its a fast blow, if its thicker and spiraled its slow blow.
it will have to be whatever part is in that circuit, if it's the blower you need to ohm it out and check the bearings and capacitor. if there is a wiring diagram it will help you determine what is in that circuit.
Solved by resoldering some solder joints!!!!!!!
Toshiba Model 57H81 Rear Projection TV - Purchased 11-09-2001
Problem: Toshiba 57H81 Flashing Red Power Light, No Picture/Sound, Blown Fuses F850 + F852
Symptoms January, 2009:
Upon turning on set I got flashing red power light and nothing else.
Removing plug for one minute and plugging in results in:
Audible click, steady red power light for 2 seconds then slow flashing red light
Pushing power button results in steady red for about 2 seconds then slow flashing red light, no other set activity
Removing power cord for several hours and plugging back in made no change
Audible click, steady red for about 2 seconds then slow flashing red light
Possible related note:Over past several months occasionally the entire screen would flicker momentarily and at other times be problem free for weeks.
Fuses F850 and F852 found blown
PD0074 DEF/CON Power Board
There are two main power supply capacitors in this set.They are C-809 and C-810.One their negative lead on the printed circuit board re-soldered leads and nearby contacts. I’m told that because the factory left out a printed circuit board eyelet, the connection will come loose over time.When I called Toshiba customer service they said there was a known solder joint problem causing blinking red light.
Replaced blown fuses F850 and F852.
I actually installed a fuse panel on the inside of the cabinet and routed the fuse connections here instead of ordering the special fuses and replacing them on the circuit board.
Had to use a 5 Amp SLO-BLOW for F850. Fast blow does not survive power up. Get the red blinking light.
Twelve hours of my time over three days to research issue, disassemble set, make repairs, add fuse panel.
Already owned Service Manual and Circuit diagrams from a different 2004 repair.
Less than ten dollars at Radio Shack for fuses and fuse panel. Already had wires, etc.
Some solder. Already owned de-soldering tools, etc.
Visited both local authorized Toshiba factory service repair facilities.One said repair would have to include replacing Q751 + Q752 STK392-110 Convergence Amps with ST392-180, and realigning set for a total of $500+ and it would be more if they had to order a power board. NO THANK YOU!Other shop said $65 for site visit and $30 to make an estimate that could be applied to repair.
I had the same problem. The screws around the perimeter of the back plate must be unscrewed and the plate must be pried off as it is glued to the box. When replacing my fuse, 2A 5x20 GMA, it blew the fuse again. Disconnecting the second circuit board prevented the next fuse from blowing, but now the question is what is wrong with the circuit board? I cannot see any damage or shorts.
