Question about Dacor DMT2420 1200 Watts Microwave Oven

Open Question

E wave microwave stirrer blade and coupler are done

Hi,
Yesterday my microwave was making sizziling sounds and we opened it up and took off the stirrer cover, the stirrer blade has black on it egdes and I think the plastic piece holding it in place is called a coupler. Well that piece looked melted. The microwave still seems to work with out these parts. First is it dangerous to use the microwave without these parts. Second we were able to find a new stirrer part and cover on repair clinic, but they don't have the same coupler is it okay to use a different one.
Thanks so much,
Laura O'Leary

Sounds like some metal is involved somehow. If the unit otherwise works, replace the damaged parts. Test with a cup filled with water.

You would have to order control panel frame assembly ("panel med assembly"), which contains the keypad and bezel.

To replace it, you remove the control panel assembly, take out the circuit boards, and place them in the new frame.

Here are the part numbers:

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven. You may have to cut the cover off with snips, then use a screw when reassembling it.

Here are those part numbers:

66388 Turntable motor
66489 Turntable coupling

You can order either of there here.

Does the microwave rotate during cooking?


Most microwave ovens have a "stirrer" blade run by a small pancake motor to help avoid standing waves and hot spots inside the microwave cavity. And most modern microwave ovens have a turntable to turn the food, to provide even more even-distribution of heating.

GE Spacemaker XL1800 sparking from behind wave stirrer cover


Microwaves use a magnetron to generate microwave energy and direct it a rotating blade wheel to spread them around the inside of the oven. If there is any metal in the area to be heated, or any of the blades are bent, even a bit, the microwave energy can be reflected back up to the magnetron area. In this area there is now too much power and it sparks away, so it does not heat the item in the oven.
Because it is sparking it is now a safety hazard the sparks may melt and set fire to plastic parts in it. This is serious it could burn your house down. Bin this microwave and cut the cable off it to make sure no one else ever uses it.

The oven has trouble ligting,and make,s a boom sound when lighting


Magnetron


If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.

Stirrer Motor


If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.

Turntable Motor


If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.

Timer functions, fan works, great humming noise, no heat. Magnetron??


If there is no heat at all, but you can hear the magnetron humming, it is probably bad. if there is uneven heat, the wave stirrer that distributes the microwaves around the cooking chamber may be bad. it will heat only one spot unless the wave stirrer is rotating.

HI, I NEED TO REPLACE THE PLASTIC DRIVE SPINDLE ON THE BOTTOM OF MOTOR HEAD UNIT, THE STAINLESS SHAFT WITH THE BLADE STRIPPED THE PLASTIC INTERAL OF THIS PRESS ON SPINDLE. THANKS


It sounds like you're talking about the coupler on the stirrer motor.

On some models, it available separately, but on some, you have to order a new stirrer motor.

Not heating


Remove the outer cover (pull the power plug first) and look for a blown fuse. If found, replace the high voltage diode and the 'stirrer' (a fan-like device located within the sheet metal wave-guide near the opening in the cooking cavity where the microwaves come into it). This stirrer has a plastic bearing that frequently arcs over and permanently shorts out the microwaves which blows the fuse. If no blown fuse is found, look for a loose or defective door-interlock micro-switch.

My Whirlpool microwave model MH9181XMT started making a loud noise while running (it sounds like a wobbly fan) It continues to heat and run perfectly but with the noise. Any ideas?


Assuming you already ruled out the exhaust fan there are 2 stirrer motors, one for the turntable and one for the stirrer blades in the top. One of those could be bad. eric

Turntable in GE microwave stopped turning.


On some GE models, the turntable motor and stirrer motor are powered off a tap on the internal cooling fan motor and in such cases they will be marked "21V AC".

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the turntable and stirrer won't work, and magnetron will soon be destroyed.

A quick test is to remove the stirrer cover in the ceiling of the oven. The owner's manual tells you how, and you can download that here.

Then run the oven for several seconds with a cup of water inside while watching the stirrer blade in the top. It should turn very slowly.

If it does not turn or is jerky, it or the cooling fan is not working.


Also, we have a sound clip of what a microwave should sound like when the cooling fan and everything else is working here. The cooling fan's absence will be notable after you hear the clip.

The turntable system otherwise consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If the cooling fan is good, but yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

Accessing some parts may require you to pull the oven from thew wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Coupler has stopped turning


The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

But first you should also be sure that the internal cooling fan is working, because in this model, that's where the stirrer and turntable motors get their power - from a tap on the cooling fan motor!

Probably the easiest way to check this is to remove your stirrer cover, place a cup of water on the tray, then microwave for about a minute.

Watch through the glass and see if the metal stirrer is slowly rotating.

If not, the problem may be a bad cooling fan.

It is vital that the cooling fan runs, or the magnetron will be destroyed, too.

If you're not sure how to remove your stirrer cover, it's covered in your owner's manual.

If for some reason you don't have your owner's manual, you can download GE owner's manuals and installation instructions here.

Hot Spots in my Spacemaker Microwave Oven JVM14OH001


Okay, I see now.

That would be the "stirrer blade assembly" part number WB2X9935.

It comes as an assembly, with the stirrer blade and what looks like a coupler.

GE sells it for $98, but you can get by searching for part # WB2X9935 here for only $55.61.
