Microwave has no power

If your GE Spacemaker XL 1400 microwave oven is not turning on, there are a few things you can do to diagnose the problem and try to remedy it. First, unplug the microwave oven and plug it back in again to supply power back to the oven after a power surge. Second, make sure the door is firmly shut as the oven does not operate unless the door is completely closed. Third, check the breaker box to make sure the switch associated with your microwave oven is not flipped to the "Off" position. Finally, press and hold the "Clear/Off" button on the front panel if the "Locked" message appears on the display. If none of these steps work, then the problem could be anything from a defective control circuit board or a burned out magnetron tube. Either fix is quite expensive and you'll have to evaluate the cost of repair versus the cost of replacing the microwave oven.

>> 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.

i suggest you go to wal mart and purchase another one after you check your power outlet with another item before you do replace it or try plugging it in else wjere if none of the suggested things i have said works, i suspect its dead, i know of no one who repairs the things,, due to there usually throw away cheap made to start with,, good luck..

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.

things needed
1.Screwdriver
2.Ohmmeter
3.New fuse

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.

On most recent Sharp microwaves, the fuse only interrupts main power, so if the fuse is blown, it will be totally dead.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes then try it.

Then chances are you have a failed microwave display. Unless this is an over the range, touch screen, or convection type, it's probably not worth repair, but you can get more information on such repairs here.

E-13 - T1 Max time error (oven did not preheat properly). PCB assembly may need reset or may be bad.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work,leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

Otherwise, Since it's less than one year old, it should be fully covered under warranty.I'd suggest contacting the manufacturer to get it fixed free.

It could easily be a bad line fuse and/or line filter. To access you will need to unplug the unit and remove the outside case. Inside the unit, where the A/C power cord comes in, there should be a small circuit card (part #237068) located somewhere with a fuse mounted on it. This is your input line filter board with line fuse. Replace the fuse, first and see if this fixes your problem. This is a 20amp appliance fuse that you can purchase at any hardware store. Make sure you place the cover back on the unit BEFORE you plug it in. It is not safe to have this area of the microwave exposed with power applied. High potentials in the 4,000 volt range are present! If the fuse does not correct your problem, the circuit card runs about $26.00. Good luck and hope this fixes your problem.

please be a little more specific no power or no functions .open cover and check fuse if no power ineed more info sorry
