Question about GE Microwave Ovens

1 Answer

Jvm2070sh001 microwave problems: the top grill was broken off and removed. The unit turns on and then off after 2 secs. The cam rotates to openb the top grill, are there any other switches that complete the operation circuit? I removed the main bd and the components were not damaged. Is a magnetron problem likely or just a new grill for the top?

The top grill problem is probably due to the grille's being broken.

There are switches associated with the grille door and if they or their actuators are damaged, it can make the grille motor want to come on (or not come on) when it should (or should not).

This exploded view diagram shows where they are.

The turning off after cooking for 2-3 seconds is a bad magnetron. See this FixYa solution even though your model number is different.

You can find links to helpful exploded view diagrams and part ordering help here.
I recommend that you bookmark that link to your favorites.You can download GE owner's manuals and installation instructions here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

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

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

I have chefmate microwave and suddenly stopped working. it is showing 2:50 code on the screen only...it was working fine and dont know what happened to it and touch pad is not working..how do i make it...


HELLO.

The code on the screen indicate electric panel fault resulting from the touchpad malfunction.

The touch pad on your microwave oven acts as the brain of the appliance. It not only contains the buttons that you use to enter cooking settings and times, but also controls the function of the entire microwave. If the touch pad malfunctions or breaks completely, the microwave will cease to function. In this instance, the broken touch pad must be removed and a new touch pad must be installed, to restore functionality to the microwave.

1 Unplug the microwave from the wall outlet.
2 Remove the two screws, located on the front or top of the grill at the top of the microwave.
3 Pull the grill off of the microwave.
4 Remove the mounting screw from the top of the control panel.
5 Lift the control panel up and out to loosen. Look behind the control panel to ensure there are no metal tabs securing the control panel in place. If there are metal tabs, gently rotate the control panel to free the tabs.
6 Transfer the wires from the old control panel to the new control panel one at a time to ensure that the wires are properly installed.
7 Install the new control panel into the microwave and secure using the mounting screw that was removed.
8 Replace the grill from the top of the microwave and secure it using the screws that were removed.
9 Plug the microwave back into the wall outlet.
Thanks.

How do i change the light bulb? Panasonic model NN-T945SF


Hi,

Do you mean you want to replace light bulb for your microwave? If yes follow the instructions below;
  1. PLEASE UNPLUG YOUR MICROWAVE!
  2. Picture of your microwave with a phone or camera so that you don't forget how to assemble it back.
  3. Remove the two screws that holds grill. They are located at the edge of the unit. Once the screws are out, rotate the grill forward from the top. It will pop right out.
  4. Once the screws are out, rotate the grill forward from the top. The grill should pop right out.
  5. Locate a small access cavity on the left.
  6. Remove the screw that is located near the front of the microwave door.
  7. Lift up the sheet metal floor to access the bulb. The bulb is located under the sheet metal "floor" on the left.
  8. Place a flash light on the microwave floor and shine the light in the light area. This will help you see better when you replace your bulb.
  9. Look for a small shiny reflector that hides the bulb. Use your two fingers to squeeze it a bit. Making sure not to bend it.
  10. The bulb connection should come right out.
  11. After you replaced the bulb, re secure the reflector and the sheet metal floor with the single screw. Test the bulb by plugging in your microwave.
  12. Once you see that the bulb works. Unplug your microwave again and re attach the front grill. You are now done.
I hope this helps to solve your problem.

Good luck.

Jenn-Air Microwave vent grill opens and closes


I have this same problem occasionally. Pull the vent grill open and look for a white cam that rotates when the microwave is on. To the right of that cam, there are two gray switches. The bottom switch should have a red tab that pops out. When the vent grill opens and closes continuously, the red tab is stuck in. Take a flat screwdriver or tooth pick and push gently in on the red tab to release it. It must get stuck due to grease or dirt accumulation. Good luck.

Approximately 1 month old? Should still be under warranty. Before doing anything else, contact the store where you purchased the oven and see if they'll exchange it as defective. If not, they may take the unit in for service there. Failing that, check your owner's manual to see what to do for service.

Ge spacemaker microwave jvm1630bkc


it is just behind the front top grill on the right. The plastic grill that goes accross the entire top of the front of the unit. Then behind it on the right is a small power board that has the ceramic fuse on it.
remove 2 srews from top of microwave that hold the top of this plastic grill in place.
Then slide the grill to the left or right (I don't remember which way). Now the grill will come out.

The fuse is usually the secondary issue. Most often, it is the cavity TCO that goes out. This is the thermo-coupler that breaks the main power circuit if the inside of the mocrowave gets over 100 degrees C. requires taking the unit down and taking the cover off.

Fan and light buttons pushed in, how do i install new buttons.


I just fixed mine. Same problem.

  1. remove the top vent (like replacing filter) w/ 2 or 3 screws on the top of the unit
  2. Remove the one screw on the top of the clock/control unit.
  3. Remove the clock/control panel by sliding up then out
  4. See circuit board at the bottom for the 3 switches. Hopefully it just popped out of place.
  5. pop it back into place and re-assemble
  6. if it's broken, you'll have to find the replacement part here: http://www.geappliances.com/service_and_support/
  7. If the actual buttons (black plastic) are broken, you have to replace the whole plastic housing for the electronics. Probably a big project and/or you'd replace the whole bit for hundreds of dollars, but even still, it's a pop-out, pop-in.
Good luck,

Change a JennAir JMV8208aa Microwave light bulb


Inside light

1. Disconnect power to oven.
2. Remove screws located in front on top of microwave securing grille.
2. Remove grille.
3. Remove screws securing bulb holder.
4. Remove light bulb

Cooktop lights

1. Disconnect power to oven.
2. Remove lamp cover or remove screws securing bottom plate cover.
3. Disconnect lamps.

If your bulb is stuck or physically broken, it can be a pain. It's sometimes tacked in place with hot glue, and sometimes there may have been enough moisture to corrode and seize up.

You could heat it up (hair dryer, maybe?) then use needle nose pliers. Be careful if heating so you don't burn anything.

You may be able to put the tips of needle nose pliers inside the broken bulb's socket, gently but firmly force the pliers jaws apart and then rotate the pliers to loosen it.

Another cool trick is to put a big glob of hot glue on the end of a stick or dowel, then shove it into the broken base and let it cool about 5 minutes, then turn the stick.

I like to put a little WD-40 or rust buster on the threads of the new bulb, too. Grease, Vaseline, cooking oil, or anything like that will work. Just a thin coat.

The lamps are available at most grocery stores, hardware stores, home centers, and places like Wal-Mart and Lowe's.

If the unit uses halogen bulbs, do not handle them with bare hands, as oils from the skin make them run hotter and shorten their lives.

Removing Old Built-In Microwave


You did not note your Make and Model. As there are many different types, all I can give you are basic directions.
First make sure the Power Cord is UN-PLUGGED from the wall.

1. Remove the Top Vent Grille Cover. There are screws holding this on, either Three you can see (one on each side and one in the center), or Open the Door and look for screws at the top of the Frame that go Up Into the grille.
2. Look in cabinet above unit for screws that hold unit up. Usually two (one on each side, front), can be more. Remove.
3. Look where Top Vent Grille Cover was removed. There should be a Long Screw or Screw-Type Lock at each( top) corner. These hold the unit tight on the Wall-Mount Plate. Remove. You should have HELP at this point as you will slide the unit forward until it comes clear of the Support Arms.
GOOD LUCK!!
