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.

Yes, most likely there is a fuse that has blown, but most of the time a fuse does not blow for no good reason. There is probably a short in the woofer output amp that has blown the fuse. Good Luck

Dryer not powering/turning on


Investigate these areas if your dryer is not starting: Proper Voltage from the House Your dryer may not be receiving adequate voltage to start. Make sure your dryer is plugged in. Also, check the circuit breaker panel to make sure all the circuit breakers are in the correct positions. Or check to make sure no fuses in the fuse panel are blown. Try plugging something else into the same outlet. If it won't work either, then there is likely something wrong with the power outlet. Any of these could be the reason power is not getting to your dryer. Also, refrain from using an extension cord to plug your dryer in. Door Switch If your dryer's door switch is defective, it will not allow your dryer to start. Test your dryer's door switch. If it is defective, replace it. Start Switch A dryer cannot start if its start switch is defective. Test your dryer's start switch. If it is defective, you will have to replace it for your dryer to start again. Thermal Fuse A thermal fuse is a heat-sensitive fuse attached to your dryer's exhaust duct (in most models) that is designed to blow if the dryer overheats. A blown fuse would cause your dryer to not heat, or to not work at all. Open up your dryer's cabinet and locate its thermal fuse. Test the component. If it has blown, replace it. Thermostat A defective dryer thermostat could be what is preventing your dryer from starting. Open up your dryer's cabinet. Test each of your dryer's thermostats. Replace any that have become defective. Timer Motor Your dryer's timer will not function properly if its motor is malfunctioning. Open up your dryer's cabinet and locate its motor. Test the component. If it is not functioning as it should, replace either the motor itself, or the entire timer assembly. Motor A burned out motor could be what is keeping your dryer from starting. Test your dryer's motor and if it is defective, replace it. You will have to open your dryer in order to gain access to its motor.

Power doest not come on


Assuming ,that the outlet that you plugged your cd player in is working properlly.Try taking the cover to the cd player off. There should be a fuse, somewhere on the circuit board. Check to see if the fuse is blown.If it is replace the fuse, with the same type fuse. There should be writing on the metal part of the fuse,which will tell you the voltage,an amperage of the fuse. If it is blown, take the fuse to a Radio Shack store, they'll be able to match up the fuse for you. There might be more than one fuse, on the circuit board. Also,are you plugging the cd player into a G.F.I. outlet? The outlet could be tripped. If it is, hit the reset button.This should reset power to the outlet. There might be other outlet's that are wired into the G.F.I. If the G.F.I. is tripped then those outlet's won't work until you hit the reset button.

No power to microwave


Hello

Check the Power Cord

Verify that the power cord is properly connected the outlet; the plug might have been removed to make way for another appliance. Do not connect the microwave to an outlet via an extension cord or plug adapter; the oven must be directly connected to an outlet.
Switch the Outlet on

Turn the outlet on, if possible, using the switch on the wall behind the counter or on the plug itself. Some microwaves have a separate power switch that must be in the correct position before you can begin cooking.
Reset the Oven

Unplug the oven, wait a few seconds and reconnect the power. A power surge could have temporarily rendered the oven inoperable. The oven should start up as normal when you connect the plug to the outlet.
Check the Fuses and Breakers

See that the fuse or breaker protecting the oven's circuit is still active. Replace the fuse if it has blown, or reset the breaker to restore power to the oven. Stop using the microwave if it repeatedly blows fuses or trips breakers.

GE microwave oven model#JVM1441BH04 when you close door on switch activates and oven comes on. Only goes off when door is opened.


HELLO.

the problem your are experiencing with your microwave oven is a failed interlock switch.
Be careful when closing your microwave door. Slamming the door too hard is one of the main reasons that the interlock switch is damaged.

Slamming the microwave door shut can easily blow the microwave fuse, but they can also blow due to problems with the interlock switches.
A microwave oven will not function until the fuse is replaced.

Instruction on how to replace fuse on microwave.

1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.

2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.

3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.

4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.

5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.

6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

thanks.

HELLO.

take on these steps to solve the problem.

Check if there is electric power on wall outlet.

If the microwave plug has fuse,check if it has not burnt.if these are okay there is need to take the last step.

Tv will not come no timer lite blinks


Things You'll Need:


  • Electrical outlet
  • Fuses
  1. Check that the power cord is securely plugged into the power outlet.

  2. Make sure that the power outlet is receiving electricity by plugging a different device into the plug and turning the power on. If the other device does not work you likely have a blown fuse or tripped circuit breaker.

  3. Replace the blown fuse or reset the circuit breaker as needed. If it happens again, an electrician should assess the problem.

  4. Contact akai Support if Steps 1 to 3 do not solve your problem. Only a trained service technician should attempt to fix the power problem with your television

The accessories 12 V plug does not work but the cigarette lighter plug location does. I've checked all the fuses and can't find the blown fuse. Where is it? I've checked under the hood and the side of...


I don't have a solution for this problem(yet) but have the exact same issue with a 2005 Silverado. All fuses are good and the cigarette lighter outlet works fine. I am looking to get my hands on a copy of the wiring diagram for this truck. I suspect that there is an inline fuse somewhere in the system that has blown but haven't been able to locate. If anyone has a copy of the service(or Haynes) manual for this truck, I would appreciate a copy of the wiring diagram that shows the accessory outlet.

It will not power on


henrylshelt,
Your sub should turn on into standby mode when plugged into AC power without being attached to the receiver. If it does not follow the list below. If it does, the sub needs a signal from your receiver via either by line-level (RCA) or the speaker wires to turn on out of standby. Ensure that the cable or wires going to your sub is in fact sending a signal while the receiver is on. To Test, (speaker wires) hook up a different known working speaker; (line-level) Some receivers have a menu option to turn the LFE output on and off, ensure that it is on and producing a signal.

Diagnose the problem:
1) Remove all wiring to/from the unit except for the AC plug (use a different known working AC outlet), will it turn on? If so the other outlet is not working.
2) Remove the woofer, does the amp have a fuse that need to be changed? Change the fuse. If it blows again after replacing and turning back on, the speaker is blown; go to #4.
3) Unplug the woofer from the amp, does it turn on? If so, go to #4.
4) The sub need to be serviced. http://www.jbl.com/EN-US/Support/Pages/SupportOverView.aspx

-Hope this helps, Chris.

My cigarette lighter is not charging in my car what could it be?


You mean there seems to be no power to the vehicle's lighter unit outlet.

This lighter unit outlet is normally wired through its own fuse so check the fuse panel in the car for a blown fuse. If blown it must be replaced with a fuse of the correct amperage. The owner's manual will show you where the fuse is located.

Before you check the fuse just check the cigarette lighter outlet with another plug-in device if you have one such as a portable 12 volt tire compressor or a 12 volt plug-in auxiliary light. It could be that if you are using a charger from the outlet, the charger plug or wiring may be faulty rather than the car's power outlet itself. (These outlets don't usually give trouble unless the wiring has been messed with or the outlet itself has been damaged or abused).

If no device works from the lighter power outlet check the fuse as it may be blown.
