Top 20 Maytag MMV5000 Microwave Oven Questions & Answers

It would be helpful it you would also post the Brand and the Model number

take the cabinet off and switch with the same type fuse

The main fuse has blown due to a failure in the microwave circuitry.

push twice the stop button

Hello,the control board needs to replaced for the touch pad to respond well again.Regards.

Hello, welcome to Fixya!Your unit is either having a power problem or a display problem. But it is most likely a display fault.Click the below link and let us fix it together.For detailed info, click here: http://www.fixya.com/marketplace/servicepage.aspx?srvid=15749Good luck.

You can find links to helpful exploded view diagrams and part ordering help here. I recommend that you bookmark that link to your favorites.Running the oven empty will overheat the magnetron. It may just be a failed magnetron thermal cutout (also called a thermostat or TCO) or the magnetron itself may be destroyed.

First item on this page is the owners manual for this Microwave. Smiles! :-)

That looks like you are in need of a replacement key pad.
I can't advise where to get one from as I don't know which country you are in.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Load test.

A simple safety test.
Place 1/2 litre of water in a glass container. Measure the temperature of the water.
Place in microwave and heat on full power for 1minute.
Measure the temperature after it has stood for 1minute.
If the temperature difference is more than 9 degrees Celcuis the magnetron is working and producing about 700Watts of heat.
If your microwave is labelled with 900 or 1000Watts. That is about right.
If the temperature is less then the magnetron is not working properly and may need replacing.

This a only a rough guide and any doubts you should consult an authorised service agent.

check power between power cord connection and inernal fuse,start at cord connection and work way to fuse conn.eliminating possibe problem area

remove the outer cover and unplug unit,then discharge the high voltage capacitor and check its capacitance with a capacitor checker,then check the high voltage diode in this circuit also,if they open up the high voltage doubler circuit won't produce the high voltage necessary to operate the magnetron tube to heat the food contents,also the magnetron can be going bad or can be loose setting up a vibration in the unit producing the hum also,your control board also has a relay in this unit that can also affect operation of unit heating and lighting

Hi,

Replacr the internal fuse you will find when you remove the cabinet. It will be near where the cord enters the cabinet. It is a special fuse ... get a replacement at most hardware of appliance parts stores.

bought a new microwave;

Please check the door safety interlock switches. These are the micro switches inside the case that tell the oven the door is closed. When you open the door while the oven is running, there is an arc on the contacts in the switches and they burn a little. After a while, the switches are no longer able to report the door is closed. When the door is not closed, the heat is not turned on. Forget what you know about the door being closed.

Check the switches.

If nothing works, it sounds like you didn't get the cable inserted properly. It should fit into a connector which carries signals to the microwave's control components. These connectors usually pullup, you insert the cable, and push the connector back down.

The answer to your question is, Yes. Click on this http://www.partselect.com/MultiModels.aspx?ModelNum=mmv5000&SearchTerm=fuse&RefineSearch=0 and the part you see labled as #5 is the fuse you will need to replace. Take all the screws out around the back that are holding the outter case on. Once you have the case off, look back behind the touch panel. There you will find the fuse, mag tube and a lot of other parts. You can use a meter to check the fuse before you replace it and if it's good your mag tube will most likely be the problem. Good luck
