So you mean if you do regular cooking it works okay, but only fails when you press the "Add 30 sec." key?

This would most likely be a bad high-voltage transformer, not a problem in the keypad or control board.

If my understanding of your problem is not correct, please correct me and I'll be happy to help further.

This is likely worth saving, but I would need a little more detail.

There is a short either in the keypad or the power board.  Unfortunately parts for this one are not available anymore.  If you could get the parts it would cost you well over $100 and would be a better idea to replace the microwave.  If this only happens when you add time then I would just use the microwave without using that option.  Would appreciate a solved rating for expert advice.

My Maytag Microwave is blowing the 250v- 20a fuse behind the key panel on the black wire. It melted the fuse holder mounted to the main body of the unit. Any thoughts on why?


The magnetron is shorted, the keypad control board is bad, blowing fuses. If less than 7 years old it has a inverter board that can be trouble, But with the level of work and parts it will easily exceed the cost of a new microwave oven.

Hi ..Our Microwave stopped working. It is a GE Microwave- Convection Oven in wall combo with control panels for both ovens shared. Convection oven works fine. Microwave has no power...it is dead. ...


There is often a fuse and a magnetron thermal fuse or thermostat.

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.

My microwave is completely dead. I have checked the fuse in the plug and it is fine. Any suggestions?


Hello,

What you are to do to solve the problem is to do a general troubleshooting on your oven below are instruction to follow.

The Microwave is a counter top model with a variety of preset cooking options, including timed cooking at a variety of power levels and sensor-cooking settings for popcorn, rice, beverages and single-serving reheating.

The sensor cooking and reheating features detect increasing humidity levels inside the microwave and automatically adjust cooking time for various types and amounts of food. This microwave also includes a turntable and an electronic control panel.



Instructions below are step by step solution for your oven

  1. Check to see if the microwave will start. If it will not start and the display panel is blank, you may have a power problem. Unplug the microwave and then plug it back in, making sure that all three prongs of the power cord are fully inserted into the wall outlet. If this doesn't work, check your home's fuse box. Reset the circuit breaker to restore if necessary.
  2. Ensure that the microwave door is fully closed. Press the Clear/Off button to cancel any previous cooking instructions. Re-enter your cooking program, including cooking time and food weight if necessary, and press Start.
  3. If "Err" appears on the microwave display, press the Clear/Off button and reenter your cooking program. The "Err" message will appear during the sensor-controlled programs (Popcorn, Rice, Beverage or Reheat) if the door is opened before steam is detected or if no steam was detected within the maximum amount of time allowed by the microwave. Be sure to leave the door closed during these programs, at least until time is shown counting down on the display panel.
  4. If your control panel will not work or if an "L" is displayed on the screen, press and hold the Clear/Off button for a full three seconds to unlock the control panel.
  5. If your sensor reheat program is resulting in under- or overcooked food, first try decreasing the amount of food in the microwave; the sensor programs are designed for single servings of food. The sensor reheat function works by measuring humidity inside the microwave--do not use a tightly-covered dish with this setting because no moisture will be able to escape and the food will overcook. Be sure that cooking containers are dry; moist containers will increase the humidity in the microwave and mislead the sensor, resulting in undercooked food.
  6. If your turntable is not rotating, first check to ensure that your food container is positioned so that it can freely rotate without hitting the microwave's interior walls; using a smaller food container can fix this problem. If the turntable still will not rotate, lift the turntable from its support and replace it carefully, ensuring that it rests evenly on its support.
Good luck.

Thank you and thanks for using fixya.

Dead Microwave


Check your plug and change the fuse there also.

You might need to rechange the 20 amp 250v fuse behind the control panel again due to the recent spark.

If none of this works then i'm afraid a certified technician needs to check the power packs and boards

No display on microwave touchpad for ge Model JKP62G


The GE JKP62G Microwave / Oven combination has an internal fuse behind the control panel for the microwave. The oven will operate but the microwave will be totally dead (no light, no clock). Turn off the breaker for the oven at the fuse box (30 Amp double breaker). In order to replace the fuse you will have to open the door to the microwave, remove the two screws (Torx) from the front control panel (located on the left edge of the control panel), wiggle the panel to the left (there are two metal tabs that stick into the metal frame of the microwave on the right of the panel) and then tilt the panel down from the top. There is a metal bracket that holds the control panel to the microwave at the bottom (don't remove it). Look towards the top of the microwave inside the area behind the control panel and you will see a 15 Amp screw in fuse. Replace the fuse and that should fix your problem.

Makes a loud humming sound and blows fuse behind controll panel


Most likely a shorted capacitor is causing the fuse to blow. Easy and cheap to fix.
