MMV1153BAS Maytag Microwave - Instructions

Why a tenant would remove and discard the grease filters without replacing them is beyond me! But, I removed the filters from the package and slid them into place. Two minutes tops. I would like to add that I ordered these on Thursday afternoon, and I had them on Saturday; awesome customer service!

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.

Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those were a little more complicated but still easy to do.

Now the Microwave works just like new! Cost me less than $100 for all parts.

The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.

You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.

You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi meter. Search for the procedures on YouTube.

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.

When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.

In the end I ordered a new microwave.

I ordered a new coupler and dropped it into the center hole, jiggled it until it fell into place, put the turntable back on the track, and voila, fixed! It was ridiculously easy.

First I read through the customer comments, reviews, questions, etc. at Parts Select, which is always a good bet. Then I put "samsung microwave door switch replacement" into youtube and watched some videos. They don't even have to be for Samsung. From what I can tell, many of the appliance companies use the same design and the same junk parts, so watching a GE video is almost the same for example. Watch some videos to familiarize yourself with the steps. There are maybe six to disassemble and install the new part. I replaced all three switches. They are not expensive and to replace 3 is only 5% more work than to replace just one; you have to take the microwave apart in either case. UNPLUG THE MICROWAVE FROM THE WALL. Start taking it apart. I use my phone to take a picture of any thing I remove, unscrew or disconnect, especially wires, BEFORE I disconnect them. Thee pictures serve as a reference when I go to reconnect and reassemble. If I am uncertain then I check the picture. Good luck!

I replaced all 3 door switches. Once you remove the top vent then remove the panel. Then remove the two screws holding the door switches in place and pop them out and replace them. It was tricky getting around all the wires but eventually was able to get around them. Took less than 20 mins to do and was less than $40 to fix. Much better than having to replace our over the stove microwave.

Unplugged the unit. With a screwdriver removed two screws on the top plastic vent. This exposed the screw holding the control panel. Removed that screw to access the switches. Removed the visible connected wiring from the switches. Grabbed each switch with pliers to gentle pull them from their holders. Inserted new switches and reconnected wiring, ensuring the correct orientation of switches in their holders.
Recommend replace all three switches.

By removing one phillips headed screw, a metal frame pivoted down for easy replacement of glass plate.

Searched for a YouTube video that included “replace Samsung microwave body latch” (whatever part name). There are plenty of easy how-tos.

Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides. Place the microwave on a chair so it can stand with the controls up. You are replacing the lower door microswitch. The switch is located behind the control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.

REPLACED DOOR SWITCH ASSEMLY

I unscrewed one screw and droped the glass light bulb cover, bent the light bulb up so it wouldn't break the glass again, removed the broken glass and installed new glass by bending the tabs over the glass to hold it in place and re-inserted the cover, then screwed the retaining screw back in. Done in 3 min.. PartsSelect.com seems to be one of the few online parts ordering place that has schematics and easy to navigate site. Perfecto!

Based on my research, this over the range miscrowave should have come with 2 templates: 1 for the wall and 1 for the underside of the wall cabinet. The challenge was to measure every very aspect of that microwave in order to obtain placement specs for the mounting screws. Tip: I made the holes through the top cabinet bottom a little larger than needed and used big washers with then for stability to gain the most "play" in the self aligning screws. Worked out well. Took 2 tries to get the wall plate perfect so have precision in mounting that piece.

Ordered part and screwed in. Part could not be found in hardware store even though it was just a long set of screws. Agent quickly identified part with model number of microwave and it was at my home the next morning for installation. Great service!
