The problem can be solved my unit blew the fuses on the harness and actually melted the plastic that held the in line fuses in so i went to pep-boys and bought 3 hevy duity in-line fuses and cut and spliced them into the harness removing the 3 original factory in-line fuses and i never had that problem again and also for the cars radio fuse i replaced it with a higher amp fuse so i took out the 1amp red fuse and replaced it with a white 25 amp fuse or u can use a green 30 amp fusethey are all the same size they just dont blow with the new power load of the radio.

Keeps blowing out fuses.


Hi Jeffrey,
There is some short circuit in the power supply board which is causing this. Do not just go trying new fuses, it may increase the damage. Please consult the TV Tech to take care.
Good luck.

Tv won't power on...


When you are sure the power cable is in and the mains is "on" (no fuse blown in house) you have to assume the defect is in the TV. Can be a blown fuse, or a defective power supply. Both do have a cause, a fuse blows because the power supply wanted to drain more current then allowed. (only seldom it blows because it is old) The power supply can be defect, because a component went defect, or because a defective circuit pulled to much power.
When you don't have electrical or electronic skills, please leave the repair to a service or repair centre

Peavey XR8600 can't get it to come apart


And why would equipment blow a fuse the minute you turn it on? Well, I would say because it's defective. Bad power supplies, burnt components, shorted diodes and/or transistors or dead IC's. It's repair shop time bud and make sure that shorted speaker wires or defective speakers didn't damage it, as reconnecting a freshly repaired unit to the same wires/speakers could damage the unit twice.

Hey i have a scosche in-line fuse block i purchased. I haven't had any problems until recently. My fuse fried. So i bought more and went to replace it and every fuse i try instantly fries. i cant seem


Most likely the amplifier you have hooked up to that fuse position is defective and causing the fuse to blow. Or you have a short in the powerline somewhere. Disconnect the power wire from the amplifier, tape up the end so it won't short out to anything. Replace the fuse, if it doesn't blow then you will need to get the amp checked, if it does blow, then you have a short somewhere along your power wire.

A whirlpool gas dryer will not heat up


If your dryer is not getting any heat, you need to make sure there is nothing blocking the vent. IE: LINT. Air flow is key to efficient drying. Make sure the dryer settings are appropriate for the clothes you want to dry. The timer selection, fabric selection, and the temperature selection all play important roles in proper dryer operation.
Check the heating element, burner operation, ignitor, thermal fuse, and the wiring (power cord).
• Heating element (For Electric Models)
• Burner operation (For Gas Models)
• Ignitor (For Gas Models)
• Thermal fuse
I WOULD START WITH:
To protect from over-heating, many dryers use what's commonly called a thermal fuse. If the thermal fuse gets too hot, it will blow, and completely shut down your dryer until it is replaced. This fuse is often mounted within the exhaust duct in the back panel. It's about an inch long, and is usually found within a white plastic housing. When fuses blow, it means they have no continuity and no power will flow through it. A bad thermal fuse needs to be replaced. When replacing this fuse, check the dryer vents to make sure there is no lint buildup which can cause the heat to stay trapped and blow the fuse again.
Visually inspect your heating element for any broken or burned areas.Check the coil for continuity with a Volt Ohm Meter. If there's no continuity, it means that the element is bad and you need to replace it.
If the ignitor is cycling without the burner lighting, you probably have defective electrical coils in the gas valve. These coils look like black cylinders with wires coming out the top of them, and are located near the burner valve assembly. When they get power, they open up and allow the gas to get through to the burner. If this is a new installation, make sure the gas valve is turned on.

I recently purchased a denon av surround re- ceiver avr-2805,and a set of cerwin-vega LS-15, (separetly). When playing a cd though my dvd player, at around 0.0dB and up the fuses will blow in both speakers...


Depending on the wattage of the amp to the wattage off the speakers depends on what to use and how to control them..If your speakers are rated for more power than the amp can produce it will blow the fuses just as if the amp is rated for more than the speakers it will blow the fuse..Those type of speakers do need a good supply of power to run and speaker wire size could play an important part of that.If wire supply is to small it will over heat the coil in speakers and also blow the fuse...Look in side of the boxes to see what kind of capacitors they have on the speakers or there size to insure correct for speakers them selves..Also look at all of the wire routling in the amp to insure proper installation..Hope this helps you..Have a great day
