Question about Maytag MMV5186A Microwave Oven

1 Answer

Non-working microwave Although the light comes on and the timer works for the requested cook time, the actual microwave action is nil. It worked fine and then it didn't. I have unplugged and replugged. Is there a reset button, fuse, transistor or some small thing I can do to make it work? It's 5 years old.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

FMV156DCA turns on, cook indicator lights but not cooking, timer counts down fine too


Hello epinvegas - Try reprogramming the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and restart unit. If it proves to be ineffective, then it sounds like the microwave has a faulty magnetron, wiring failure or control board. Contact a professional to assist with the repairs.

Microwave will not work


Even though you don't mention the model number, you posted under Sharp model R-1491, so I'll assume that's it.

You say when trying to work the actual microwave, you get nothing?

We could use a little clarification, but FixYa only gives you one shot at posting a help request.

When you enter the cooking time and press "Start", if the timer counts down and the oven lamp comes on, but the the turntable, cooling fan, and microwave section do not run, then you have a bad secondary interlock (bottom door switch) or its mount is bad.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you.

Also look at this info on door switch diagnosis and replacement.

Hope this helps.

Our microwave stopped working suddenly. It's a GE JVM1330 and was made in 1996. The buttons on the control panel work fine, and the light inside turns on. We can enter a cook time, and it counts down as if...


It's one of the micro-switches (3) that are part of the interlocking safety circuit. I actually took my switch apart and fixed it, but 99% of those out there would (and should) replace the switch.

Only 1 function works at a time on mco16


That actually sounds like correct operation in that you cannot use the timer while it's cooking.

Assuming yours is model number is MCO160S, you can download your owner's manual here if you don't have it.

Page 19 tells you how to replace the cooktop lights and the cavity light.

JVM1190 wont cook


You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

Microwave turns on, but no heat or turntable movement


The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

Microwave runs for 3 seconds and shuts off


This is an inverter-driven model, and this is one way the inverter fails. Often it will tick, too, but the cooling fan may be too loud to hear ticking. If you haven't had smoke, then it may not yet catastrophic. I would bet that a thorough resoldering would take care of it. A good technician can troubleshoot and repair this, as needed, but often they will just replace the inverter. Sometimes that's actually cheaper. Troubleshooting an inverter is way too much for someone without good solid technical experience. I would call a shop and ask for an estimate to replace the inverter. Good luck.
