Fan unexpectedly on and cant trun it off

Fan comes on unexpectedly and when this happens is not controllable using the touchpad. The touch pad is working fine and will control the fan normally. Fan is also a bit louder than other microwaves I have had.

SOURCE: No lites and fan actions.

Does it heat? If so, then The problem is likely on the control panel, which we repair nationwide for $39.95 postpaid.

The light failure often occurs when a bulb goes out and the filament shorts, causing a failure on the controller.

This often can affect the exhaust fan operation, too. The lights and fan can be inopoerable or stuck on.

SOURCE: Microwave model MV-1510M is not heating, also

If everything is working normally, except for heating, the likely cause is the magnetron.  Microwaves can be dangerous to work on, as the site below points out.  If you have an ohmmeter, it is possible to check the magnetron, but be certain to follow the precautions outlined at the webpage:

SOURCE: My LG intellowave microwave's touch pad/control lights is coming on and I can set the time to microwave but the on and off touchpad doesn't want to work

Some ovens will program, but will not run if they have a defective door switch. You might want to check that first before replacing anything.

Microwave touch pad not working


test this steps and fix it. God bless you

  1. Controller is confusedA power surge or random non-reproducible action of the universe may have resulted in the controller's program ending up in an infinite loop. Pull the plug for a minute or two to reset it.
  2. Defective Interlock switchesThis can result in the controller thinking the door is open and ignoring you.
  3. CleaningCleaning solutions (spray cleaner) may have gotten inside and shorted out the touchpad or controller. If this happens remove the touchpad, let it air dry for a few days, and then attach it back on the microwave.

Microwave Buttons Don't Work
Touchpad and Control Panel


If the microwave buttons don't work the touchpad and control panel assembly are probably defective.
Touchpad


If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
User Control and Display Board


If the microwave buttons don't work the user control and display board are most likely defective and will need to be replaced. If some of the buttons work and some don't, it is more likely a touch pad problem and the touch pad will need to be replaced.
Main Control Board


If the microwave buttons don't work the main control board is most likely defective and will need to be replaced. If some of the buttons work the touch pad is likely the problem. If none of the buttons work the problem may be in the main control board.1_24_2013_5_23_47_pm.gif1_24_2013_5_24_54_pm.jpg

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 the SE code on my Samsung microwave. I have replaced the touch pad but the code remains. Any further advice? What is the purpose of the second tail on the pad; not the one that goes into the plug...


Hello & Welcome to FixYa
SE or 5E means shorted keypad and to solve this problem the keypad needs replacement, if it has already been replaced then it is better to replace the ribbon cable connecting the board. Please get back to me if you have any other questions.

Touchpad will not work after boiling water underneath it for 12 minutes without fan humidity cause touch pad to stop working , I have a GE mdv 2040 with green display touch pad


you can change the touchpad to help with this but whenever you have a microwave over a range you are going to have issues with this. you have to make sure you use the vent on high whenever broiling anything to prevent the moisture from getting in the touch pad because all your touchpad consists of is two stickers and some flat wire so moisture can easily getting into it cause it to stop working for a period of time. but changing it is the best thing you can do

Ge microwave HVM1540DN1BB button control pad stopped working


I am not familiar with the Whirlpool microwaves; however, I just had the same problem with an LG over the range microwave. Several of the positions on the touchpad quit responding to touch. In our case, it was the touchpad itself that was the problem.

The touchpad on our microwave was held in place with adhesive. We pulled it off and replaced it with a new touchpad. Everything works now. The only complication is getting to the connector which carries the signals from the touchpad to the microwave controls. We had to remove and dissassemble the door to get to that connector.

The touchpad cost about $26.00.

Touch pad on microwave doesn't work


HI, since this happen before and it suddenly fixed itself, i don't think its major. i recommend checking the ribbons for a tight fit. theses connection ribbons may be lose or partiality separated form the control board, in return, causing this fault. you can accesses the ribbons by removing the backcover of this unit. if the ribbons are in good condition, i recommend replacing the touch pad membrane.
