You have a short somewhere in the circuit. It could be bare wires touching, or if you have something plugged into the circuit the problem may be in that unit. Check everything with a meter before youburn down your building.

Old home, a electrical outlet actually has a fuse connected right to it. How to replace/install a regular outlet plug? I have a pic, but site doesn't appear to have a place to attach it.

electrical work is not for DIY
some one has messed with the electrical wiring of the house so get in an accredited electrician and consider having the house rewired using the correct ELB devices in the power box

Can two separate convection units (microwave and oven) be combined/joined into one cord and plugged into one outlet and BOTH work efficiently? The contractors I hired combined all wires to both unit

You need to have the contractors return and troubleshoot the problem free since they told you they both worked when you purchased them. There's an implied warranty here. The two ovens should have been tested before the contractor left your house to prove they both worked together.

When I plugged in my 2010 Montana 5th wheel, model #3075rl it fried my microwave, dvd player and my WII , now I do not have electricity in the bedroom part of the fifth wheel. How do you know if it is

Exactly where did you plug it into? It may have been a 220 volt outlet and if it was then you need to replace everything that blew out. Usually anything today are using circuit breakers rather then fuses.

Sharp Carousel Microwave Mdl 1875 for our RV is dead

>> We also tried plugging our toaster into the microwave plug outlet, and the toaster wouldn't work in that outlet, but worked just fine in a different outlet in the RV.

This means the outlet you plug your microwave into needs to be fixed in addition to fixing the oven. Breaker? Fuse?

>> I understand from another RV forum that microwave ovens for RVs have "special circuitry and cooling features" not found in regular countertop ovens for household use.

Not really in my experience. Any microwave supplied with clean AC power and proper venting space will be fine.

But I'd bet your microwave can be fixed affordably.

The main internal things which can result in this model being dead (no display, no light when you open the door, no beep when you press a pad on the keypad) would be the 20A fuse and the magnetron temperature fuse. There could also be bad connections on the noise filter board.

Also, sometimes a power surge can cause the power to be interrupted to the low voltage transformer on the board, and I regularly repair those boards. I can also write a technical statement to your insurance company or to an RV park as needed.

At my Web site, I have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

The relevant service manuals for this model are here and here.

You can order Sharp parts from Sears or Encompass.

Contact me directly if you need more help.

No power in the microwave. Will not turn on, no lights come on.

Assuming that your oven is plugged into an outlet with power, many ovens do have a fuse inside them. You can try to open the cabinet and check for a fuse. It should be located near the plug or the main circuit board. If it is blown, you check with an appliance supply house for an exact replacement or consult with an online supply like

Hi, in the process of moving my Black and Decker mini fridge i bumped the outlet where it was plugged in and i saw a spark and now when i plug it back in it does not work. The fans are not blowing or even...

Did you try plugging the refrigerator into another outlet? You may have damaged the outlet and not the refrigerator. Check to see if the circuit breaker or fuse controlling that outlet has not tripped or blown. If the outlet is damaged, you may want to have an electrician replace it if you don't feel comfortable doing it, or if your lease or insurance require you to have the work done by others.

If the outlet is working but the refrigerator isn't, you may have damaged the plug or cord. One of the prongs may not be making a connection to the cord. There isn't very much to a small fridge, so it's unlikely you damaged any of the internal parts. A check with an ohmmeter will tell you if the cord is good, and you can replace the plug or cord if necessary. Well-stocked hardware stores and big home repair places will have a suitable replacement available.

Microwave won't turn on. Seems like it is not getting power. I checked breaker. I am looking for a fuse. You know where one is? It is a GE Spacemaker(2 yrs old) model # JVM1440WH04

  • Make sure that the microwave is plugged into a grounded outlet. It must be a 3-prong outlet.
  • Make sure the clock is set.
  • Check to see if a programming sequence was entered. Sometimes improper programming or a program sequence such as delay start can cause the touch panel to be non-responsive. Unplug microwave or turn off house circuit breaker for 30 seconds. Plug back in, or reset circuit breaker, and try reprogramming unit.
  • Check the house circuit breaker or fuse box. If the microwave is DEAD and there is no display and nothing works- the problem could be a blown fuse or tripped breaker.

1. Have you tested the outlet by plugging in something else and confirming that the outlet is good? If another device doesn't work in the outlet, then you have a bad fuse or breaker that powers that circuit in the house.

2. If power is OK, you probably have a bad fuse in the oven. You'll need to unplug the oven and remove the outside cover. Replace the fuse with the EXACT same rating of fuse of the original.

Please get back to me and let me know what you find.

Good luck!

Have you tested the outlet the Microwave was first plugged into? Did you also plug the new replacement("out of the box") Microwave into that same outlet? If so, I would suspect a problem with That Outlet. It's Blowing the Microwave Line Fuse (fuse inside Microwave).
