Question about Maytag MMV5186A Microwave Oven

1 Answer

Slow Heating We ahve a maytag MMV5186AA above counter microwave.  Recently it has been slow in heating food.  As an example a cup of water left in for 2 minuets is still cool but set for 5 min. is boiling.  Have power setting to 100% and have tried unplugging the unit to reset it.  Thanks for your help.

    How old is the unit? water is a poor example for determing heating times due to ground temperature changes. Also supply voltage can be a culprit, altough rarely. Try testing with a food items known cooking time and compare the 2. Example, frozen pastry 2 min. on high should be done within 2 min +/- 15 sec.

    If item takes much longer to cook then, you may have a weak magnetron tube,(buy a new oven) Note: Use recommended times on the product packages, not my example.

Water is always called for in standard microwave heating tests.

By design, water molecules are what are targeted by the microwave cooking process.

If your line voltage is correct and it is slow to heat, then almost certainly your magnetron is failing.

If it's within the magnetron portion of the warranty but out of the original full warranty, then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If you or someone you know wants to look into this, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

NOTE: There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

The microwave is not heating the food.


When it did heat food before and you used the same settings now, the microwave must be defect.
But before you are sure, put a cup with water in the micro and try to heat that.
Dry food can't be heated in a microwave. There must be some moist in the food if you want to heat it in the microwave.

My microwave oven siows down and then speeds up.


Is it still heating food properly? You can perform a basic test with a microwave safe mug or plastic cup of water. It should be boiling or too hot to touch within 1 to 2 minutes. Be careful not to overheat the cup if plastic and use extreme caution when touching or removing it from the microwave.

If it is not heating properly then the magnetron may be faulty and unit should be replaced.

Can you tell what specifically is speeding and slowing? Is it the turntable or the humming sound of the unit itself? Many microwaves vary their intensity in order to heat/cook evenly and that will vary the pitch of the sound you hear and sound like it is speeding up or slowing down. If the turntable is slowing and speeding up then there may be a bad motor and the unit should probably be replaced.

If the unit is heating adequately and the turntable speed is uniform then what you may be hearing is simple power cycling and/or fan noise.

Only trained and certified technicians should attempt repair of microwaves due to the hazards of high voltage and microwave radiation leakage if parts are not replaced properly. Although you can have a microwave repaired the cost may be equal to, or higher than, the cost of an equivalent new unit for a 900w microwave.

Microwave wont heat up food


If your microwave runs, but doesn'theat your food, verify that you have selected a cooking setting. You mayaccidentally set the timer. Test the magnetron by placing 1 cup of water in themicrowave and heating the water for three minutes. If the water doesn't heat,your magnetron is dead.

Takes about 6 min to boil 2 cups of water-generally slow on all heating


This an early indicator that the magnetron "heats the food" is failing, usually they will go without warning and eventually will need to be replaced.

Arcing in or above oven chamberThere is often a simple cause:


  • Arcing in the oven chamber with a normal load (a cup of water, for example), often just indicates that a thorough cleaning of the oven chamber is needed, particularly around and inside/above the waveguide cover. Any food that gets trapped here will eventually burn and carbonize resulting in a focal point for further arcing. Usually, the waveguide cover is designed to be removable without taking the (cabinet) cover off of the oven. However, burnt food and carbon often make this difficult so that some disassembly will be required. See the sections: "SAFETY" and "Getting inside a microwave oven".
for more information see "Arcing in or above oven chamber" section of online Microwave Repair Manual.
If the microwave is clean, please post a reply and I will look at it again (this time include a model # and/or approx manufacture date)

Heating the cup more than coffee


make sure the stirrer motor located under the outer cover that distributes the microwaves is turning otherwise you will get hot and cold spots in the oven cavity

JVM1540DN1WW leaves food cold


Put in one cup of water at 2 1/2 minutes on high -- it should boil.

The fan slowing down is normal becaue the magnetron, which does the heating and, which pulls about 10 amps, will drop the voltage across the fan and slow it down.

What type of circuit was your old microwave using? Was it a circuit dedicated to the microwave?

We have just purchased a GE microwave oven, model JES1358WL. the light is on, the turntable turning, the control panel shows cooking and seconds counting down when attempting to heat cup of water. it is...


First: never attempt heating pure water in a microwave, that is dangerous.

Ensure the oven is not set to the minimum power, otherwise the heating will be minimal.

Try heating some food at maximum power for two or three minutes, if it does not heat, take it back to the shop.

Maytag Microwave model#MMV5186AA


Typically, no heating of food, indicates a bad Magnetron (tube) or associated components. The oven can be repaired. Magnetrons are not hard to replace and can be ordered online through MCM electronics www.mcmelectronics .

However, due to the dangers of high-voltage within the unit, I would recommend taking the unit to a repair center.

Look in the manual to see what the warranty says. See if there is any information regarding the magnetron or parts. You may be able to get it repaired for free parts, less labor.

Please let me know if I can be of further assistance to you.

Good Luck,

- Jim
