I have this same problem. You have blown the internal amp. I have had 2 of these do the same thing. There is nothing you can do but report it to infinity and try to get the unit replaced.

I had the same problem and I manaed to fix my Cuisinart SmartPower Duet blender. There are two thermal fuses, one tape attached to each stator winding. Both of mine were blown.

In addition, when the fuses blew, it must have spiked the triac. I had to replace mine. It's the black 3-legged transistor looking device with a small metal heatsink attached to it. This gizmo directly throttles the power to the motor under control of the microprocessor. There are some guides on the internet on how to test it.

Also, the clutch was very hard to remove and needs to be removed to more easily replace the thermal fuses. I clamped down the end of the motor shaft to a bench vise real hard and then I used a 7/8-inch open-end wrench to wedge into the clutch prongs which made it much easier to apply torque. Remember that its screw threads are reversed from normal screws so that it does not unscrew during operation. You have to turn it counter-clockwise to unthread it.

Hope that helps!

unhook any power source from the unit, if you can solder remove that part and take it to any radio shack , or place like that , who supplies electronic parts, and have them give you a suitable replacement , and re-install it,, be sure to check for board burns or bubbling in the line strips. this part is for one or more of the functions of your meter

Never put any fuse in it and switch ON. It has some short with internal circuit, and should be repaired before installing a new fuse. The fuse use is as a protection device to protect the other circuit parts from further damage. If you will put an other fuse, and switch it ON again, you are making things more worse than present. Find out the reason for buring out fuse. If you can do it by yourself. Otherwise get it repaired by any experienced service personal. Never make it irreparable. OK.

How can you check if a resister is bad

I use the ohmmeter function on my digital multimeter (DMM). You can get a basic DMM from Sears or Radio Shack for about $30.

First, (safety check) measure the voltage across the terminals unless you know there is no power in the circuit, or better yet, disconnect the resistor so other components don't give you a false reading. Attempting to read the value of a resistor in a live circuit will give you a meaningless number at best, and may severely damage your meter at worst. It could also damage other parts in the circuit.

Now switch your meter to the lowest ? range (Greek capital Omega, for Ohm) greater than the expected value of the resistor. Connect one test lead to each end of the resistor. The number you read should be the expected value plus or minus the tolerance (e. g., a 100 ? 5% resistor should read somewhere between 95.0 - 105.0 on the 200 ? range.). A bad resistor will usually show up as 1___ (over-range) because it will be burned out and open. Some very old carbon composition resistors will short (read much less than 1 ?) when they fail.

Often, a visual inspection will identify a bad resistor - if you can see that it's burned and broken, it's bad and further testing is unnecessary. The ohmmeter is for all the other cases.

It doesn't produce coffee after grinding. The first light on the bottom line is on.

I bought a pre-owned Delonghi Magnifica 4400 on eBay. It would grind the beans for an espresso, but then would not complete the function. Everything seemed to work fine except the machine would not deliver water anywhere-no espresso, no rinse, no steam, no hot water. I took it to the closest authorized repair shop (about 60 miles away) and it cost $260 for them to replace the "transmission system." I've had it back a few days now and everything is working perfectly...

Checking batteries

I assume a "DM-350a" is some kind of a digital multimeter. I Googled and found it might be a "A.W. Sperry DM350A 5 Function 17 Range Digital Multimeter" and looking at the ranges available on that meter, you can't really thest the battery "under load" the only reasonable way to test small batteries. the DC current only goes up to 200 milli amperes. A "C" or "D" size flashlight battery puts out 1 to 4 amps depending on conditions. That's 5 to 20 times the current readable by that meter. The volts on one of those batteries is probably 1.6 volts to 1.3 volts etc. If you live in the United States, I'd say go to Radio Shack and spend $5 to $15 and buy a battery tester like "Enercell Analog 9-Range Battery Checker, $14.99, Model 22-156, catalog # 22-156"
Then you and anyone in your family can read the instructions and test 8 or 9 different type batteries. Battery types: 1.5V button-cells, "AAA"/"N"/"AA"/"C"/"D", 6V, 9V, 12V, 15V and 22.5V..
This is not supposed to be an advertizement, and I have no interest in RadioShack,... but it's supposed to be instructional.

Small price, Good instruction to anyone who can read, and if anyone forgets, they can re-read. Testing a lot of batteries in a sitting goes very fast with these.

Differently, with the sperry, or any voltmeter, you'd have to select a resistor small enough to draw the current, and large enough not to overheat or burn, connect it and measure the loaded voltage drop, compare the voltage and current of the loaded battery, and compare it to that of a new battery, and a battery you might consider too weak for your application.. Voltage equals amps times resistance, and power equals amps squared times resistance... Really, buy a battery tester.

My receiver shut off after use & will not power on

Pop the top and check the fuse by the AC plug on the inside. Chances are you will need a meter to do this since most receiver fuses are either white or gray. If you have a multimeter, dial it to ohms and you will see a sign that looks like -))) When you touch the two leads together you should hear a tone and if digital, the display will read "1." Take the leads and touch either side of the fuse, if you hear tone, fuse is good. No tone, bad fuse. Radio Shack carries fuses of all types and usually has them in stock, and can test yours for you as well. If the fuse is O.K. then your unit needs to be serviced. It's either a power supply, transformer, or chipset. Hope this helps

Passat Indicators Blowing Fuses 2005 model

It sure sounds like a short in the left signal circuit. I can't say where the wires are routed but you may have one with failed insulation or pinched under some hardware.
You could avoid repeated fuse replacement if you buy a cheap digital multimeter from Radio Shack (if you are in the US) or alternately, from an auto parts store. One adequate for this would be under $20 US. Some have a continuity checker that sounds a 'chime' that stops when the resistance level rises a bit. Since the meter could be damaged if the short clears, it would be smart to disconnect the negative side (ground) of the battery. Putting the probes across the fuse contact will simulate the fuse for this checking but it will not let your signals function. I would punch the probes into the fuse holder, put on the left turn signal and start removing bulbs and checking the routing of the wiring. When the chime stops, you have found the culprit.

Tv Fuse Blown

Depends on how hard the fuse blew. If softly, perhaps 1 amp diff is too much.

If hard - blackened inside - then you need to call in a tech.

Hok up amp and all fuses blow on distribution block

somehow, DC car voltage has gotten to the speaker outputs of your amp! your fuses are saving your speakers from meltdown. your amp has melted down. toss it after checking with ohmeter as follows: disconnect amp completely. red wire from ohmmeter to +12Vin. black wire to SPK+. if ohms are anything below 1000 ohms, then toss it. An electrical short is equivalent to flooding your entire house with a leaky faucet. No telling what that rapid current will encounter along the amplifier section. you could get lucky and find all power MOSFETS have shorted and replace them. good luck.
