Top 20 Maytag Appliances Over-the-Range Microwave Oven Questions & Answers

not a DIY fix try another wall socket if you have no light or power to the microwave select menu the power source or an internal fault present buy a new microwave lots of warnings not to DI Y http://www.repairclinic.com/RepairHelp/How-To-Fix-A-Microwave/66---/Microwave-not-working

Disconnect microwave from power socket, remove cabinet outer cover,and lift the top or bottom door latch at micro-switch bracket with a screwdriver, the door can then be opened.

Not much data to go on here. The latch on the door has a spring that holds it down in the locked position. when you pull the handle the latch goes up and you pull the door open. You will have to take the door apart and see if the spring broke or the plastic tab that holds the end of the spring is broken.

The problem lies with the mylar ribbon cable that connects the Keypad to the circuit board. The Mylar ribbon cable folds back onto itself and are touching. Over time the mylar 'breaks down' electrically and the wire traces in the mylar will 'arc' onto the other mylar ribbon cable. The solution is to separate the two mylar ribbon cables using paper and electrical tape. I've done this on several microwaves (not just Samsung) and it has worked every time. Patience and about 20 minutes is all it should take to fix it. I've described below how I did it for the SMH9187ST Microwave Good luck to all. 1. UNPLUG THE MICROWAVE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 2. 1. Remove the top front cover by removing the (2) screws that are along the top edge (phillips). 3. 2. Slide the cover to the left about a half inch (there are tabs holding the cover in place) and remove. 4. 3. Remove (1) screw from the top of the Keypad Housing (phillips). Lift the Keypad Housing upwards about half an inch (there are tabs holding the Keypad Housing in place) and remove. Be careful of the metal grille that is just above the Keypad Housing as this may fall out since it is being held in place by the Housing. 5. 4. Be careful not to pull on the wiring harnesses that are attached to the Housing. Carefully unplug the wiring harness that has the RED connector on it from the circuit board. Carefully unplug the small white connector that has the mylar ribbon cable on it (this cable is see-through and you can see thin, flat wires in it). 6. 5. Remove (4) screws that are holding the circuit board onto the Housing. 7. The Housing should now be free of the circuit board and wiring harnesses. It's safe to let the wiring harness/circuit board hang free, but caution should be used anyway. 8. 6. Remove the thin metal frame from the Housing. There are (4) plastic tabs holding the frame in place. Using a small screw driver pry one side of the frame away from the housing (try to do this to the side that has smaller plastic tabs). When this side of the frame is free of the Housing you have to lift the frame out at an angle to remove. It might put up a fuss, but be patient and be gentle with it since the frame is thin and fragile. 9. 7. With the frame out of the way you will see the mylar ribbon cable that is coming out from underneath the Keypad assembly. You will notice that the mylar ribbon cable folds back onto itself as it re-enters the Keypad assembly. This 'touching of the two ribbon cables' is where the trouble lies. The ribbon cables may be stuck together. Carefully separate these two and then insert a small piece of paper between them (paper can be 1/2 x 1/2 ) and work the paper all the way down into the Keypad assembly as far as it will go. 10. 8. Using electrical tape, apply a small piece between the ribbon cables to hold the paper in place. Next, use more electrical tape and put it between the mylar ribbon cables enough so as to keep the ribbon cables separated. 11. 9. Re-attached the thin metal frame making sure to press it into the Keypad assembly enough so that the (4) tabs click into place. 12. 10. Use electrical tape and apply it to the raw metal edge of the thin metal frame to prevent the mylar ribbon cables from rubbing on the metal edge. 13. 11. That's it. A final word of caution. Be careful when inserting the ribbon cable connector back on to the circuit board. The connector is loose and you need to gently place the ribbon cable into the circuit board connector. 14. 12. Reverse the order of assembly from above. 15. 13. Plug in the microwave and then it should reset and ask you to set the time. Best of luck to you

Many factors at play here. Are you cooking on the range? Are you using the microwave? Is the light on? There is very little current going to the touchpad and if there were a short in it the touch pad would not work. It is just heat from another source. Don't worry about it.

Make sure you tighten all the attachment screws that may have loosened during long term usage. Make sure the fan is running properly and not causing undue vibrations. Use WD 40 on the fan.

I once had this problem. I opened the access panel (or the metal cover as the case may be) to check for a fuse and found one blown.I then replaced it with a new one. Problem solved!. Make sure it is unplugged before you start. Good Luck!

Door switch or thermostat or fuse or door switch... did I say door switch?

Please provide a model number.

You should try to at least find the same wattage. The light bulbs are not dangerous safety hazards if they are made to fit microwaves.

Chances are it has a bad top or bottom door switch or door switch mount.

Please post a new help request with the full model you mention, as well as detailed symptoms.

The common reasons are a shorted diode many use, the inverter board used for control and power, and the Magnetron which does the work

what is your model number is then we can get started then

This can be two things that I know of 1 is a timer defect and the other is someone has placed some type of metal ie utensil, foil, can whatever into the microwave - either way you should replace the microwave and its a fire hazard to your home and others around you and the cost of a new unit is not worth the losses a fire can bring.

see this causes and fix it. God bless youTouchpad If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the 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 main control board is most likely defective and will need to be replaced.

see this causes and fix it. God bless you First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.

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

The problem is more than likely in the keypad control board, pricing on this part should be checked before going ahead with repairs.
