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.

MH7115xbq  - mini_manual_behind_grille_small.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here. Just enter your full model number without dashes, such as MH7115XBQ2.

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.

Microwave oven front panel not working


The contacts behind the panel get dirty and greasy and can stop working. Remove the front panel use a q-tip and some rubbing alcohol to clean the contact pads on the back of the plastic front cover and the contact pads on the circuit board. Reassemble and it should work. WARNING! Microwaves have very high voltages in them more than 4000V that can easily kill. Make sure its unplugged from the power supply, let sit for a few hours to make sure the caps are discharged and DO NOT touch any of the high voltage lines or capacitors inside the unit, work only on the front panel.

Microwave oven whirpool model mt1100shq,it was workinh fine suddenly stopped and no power coming to it


Check the mains power to the microwave before you check for power to the unit. If the program controller is not working , check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Check this link to know how a microwave works:

http://www.espares.co.uk/advice/microwave/a/5/1443/how-a-microwave-oven-works.html

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link:

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.

I have accidentally locked my microwave oven (profile performance convection oven). I was cleaning the front. Can you tell me what to do?


Got you covered. Here you go:

Microwave - Explanation of the Child Lock Out Feature
Many microwave control panels can be locked to prevent accidental use or access by children.
There are two different ways to lock the control panel:
1. Press and hold the CLEAR/OFF pad for 3 seconds. The display will show "LOCK" and then revert to the time of day.
A small "L" will appear in the corner of the display as a reminder that the control panel is locked. If anyone tries to use the microwave, the display will show "LOCK".
2. On some models, press and hold the 5 and 7 pads simultaneously for 3 seconds.
To unlock the control: Repeat the procedure which was used to lock the control. (Press and hold the CLEAR/OFF pad for about 3 seconds or hold the 5 and 7 pad simultaneously for 3 seconds.)

I have a GE SPACEMAKER MICROWAVE OVEN MODEL #HVM1750. IT SUDDENLY STOPPED WORKING..NO SIGNS OF POWER. THE OUTLET HAS POWER. DOES IT HAVE AN INTERNAL FUSE. HAT COULD IT BE? ERIC


You know that you have to unplug the microwave first, right?Then you have to either wait a good while (I like a couple of days) or short out the current.

The fuse is located on the right side, behind the control panel at the top. You have to remove the vent cover (three screws) in the front, then the screws holding the control panel up ( I didn't remove mine, I let it rest on a pot to take the weight off the connectors). The fuse is on a small horizonal electronic board located 6 inches behind where the top of the control panel normally is attached.

You do NOT have to remove the oven, but it's small hands work, or great needle nose. You get the fuses for about 3 for $2.00 at Radio Shack.

But I bet that isn't you whole problem. Something caused it to blow.

Panasonic Microwave NN-T993SF has no power. Was working and suddenly the power went out like it was unplugged. It is not our fuses or cord but something in the microwave itself. Is there a fuse or...


most microwaves do have an internal ceramic fuse either 15 amp or 20 amp the cover has to come off to locate it usually at the top just behind the control board. do not touch the high voltage capacitor as it holds a charge even when the unit is unplugged.

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.

No display on LCD panel on my whirlpool microwave


I do not know what procedure you used to replace the door, but if the buttons and display were working fine before you replaced the door then it seems that there is a plug not plugged into the control display panel. Other than that the low voltage power supply may not be providing the needed voltage for the display and only for the logic circuits which are a different voltage. With the microwave unplugged, take the cover off and look at all the connectors and make sure that they are plugged into something and none that are not plugged in. They should all go somewhere. To answer your original question, there is only one main fuse to the microwave. The circuitry in the control panel operates on low voltages +/- 5 volts or +/-12v so that part is not fused. What I recommend also is to go back mentally through the procedure you used to replace the door and that may give you a clue as to what you unplugged, although you should not have to unplug anything.
