A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again. If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven. If it has a hood

thermostat, that should read open, as opposed to the others, which should read closed.

If you or someone you know decide to look into it, we have critical safety information 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 may also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

SOURCE: Maytag Microwave model MMV5165BAS. Doesn't heat

HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Mmv5165bas vent fan will not stop running


Check to see if there's a relay providing power to the fan. If there is, the contacts might be sticking in the closed position. Assuming that this is an over-the-range unit, disconnecting the vent fan completely might not be a good idea as heat/steam from foods cooking on the range would more likely damage the microwave.

Broken handle on maytag stainless steel microwave. Do not wish to purchase complete door assy. Could possibly substitute a black handle. Model MMV5165BAS. Kindly advise


around the inner side of the door between the window and outer frame is a plastic shroud,by gentle prying it out using a flatblade screwdriver starting at the handle side working toward the hinge side it will pop off and the screws that hold the handle can be accessed and remove and replace the handle. to reinstall that shroud gentle push it in with your fingers
you can go to searspartsdirect and enter in your model number exactly as found in the mw cavity and order the part or perhaps look in your phone and find a appliance parts dist. in your area

Model mmv5165bas Door handle is broken - how do I replace the handle? Thanks JEFF


If your full model number (from the tag in or on the unit) is MMV5165BAs, then you'll have to replace the entire door.

If your model is one of these, the handle is available separately, with part numbers below:

MMV5165BAB14 or MMV5165BAB15 black part number W10189508

MMV5165BAS14 or MMV5165BAS15 stainless part number W10187840

MMV5165BAW15 or MMV5165BAW16 white part number W10189509

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

You can find handy exploded views and order parts by model number here.

We have a brand new Maytag mmv5165BAS over range microwave oven. When we tried to make microwave popcorn using the 'Popcorn' control, the microwave stopped early and the display read E-63. What does...


E63 is a "T1 Max Time" error. It indicates a problem on the control board.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Keep a close eye on it, and if it fails again, you want to contact Maytag for free warranty repair.
