Wolf MWC24 turns on and spins. Does not heat on microwave or convection. Any ideas?


The Wolf DCM24 is a rebranded Sharp, similar to the Sharp model R-930AK, etc.

The Sharp version service manual is here, and while cosmetic parts won't interchange, internal ones will.

The problem you have is usually caused by a bad bottom door switch, or that switch's mount may be loose, misaligned, or broken.

See my help info on door switches here and here.

Once you look all this over, if you have other questions, please feel free to contact me by e-mail here.

Please include FULL model number*, FCC ID number*, + detailed symptom information. ( * on the tag in cooking cavity or around door frame or control frame or on back)

Sparks inside a wolf mw24 inside in right wall cover plate


The right side wall cover plate is the "waveguide cover."

It protects the waveguide and the magnetron at the other end from moisture, grease, and food particles.

If these remain stuck to the waveguide cover, arcing can occur, which will damage and / or destroy the cover, the waveguide or even the magnetron or the oven chassis.

As with most problems, this should be addressed sooner rather than later or it will only get worse, and may become unrepairable.

The similar Sharp model R-530E-series service manuals are here and here. They will help with disassembly, but the external / cosmetic parts will not interchange.

The Wolf waveguide number is 801798 and Wolf part ordering information is here.

The oven cavity and waveguide must be clean and if any spot is scorched or chipped, it must be sanded smooth, cleaned and dried, then touched up with appliance paint, available from local big box stores, home centers, appliance parts stores, and hardware stores.

Leave the door open overnight to dry the paint. Then install the new waveguide cover.

If the chassis or waveguide have holes in them, the oven must be scrapped and replaced.

Wolf microwave timer counts down, lights on but not cooking or making noise when started


You need a magnetron. While the cabinet is open look for melted wires, check the circuit board for burned components. Check thermal cutoffs for continuity etc

Could a blown fuse cause a microwave to not heat, fan not turn and turnable not rotate


Not likely. More likely it's a bad door switch or door switch mount.

On Sharps and those made by Sharp (Dacor, Wolf, Viking, Electrolux, etc.) it's usually the bottom door switch.

See this handy help file on door switches.

If you need further help, please reply back or post a new help request which includes your full model number and the symptoms you mentioned above.

Machine turns off after 59 seconds despite what time or power is set. plrase help!


This is a problem in one of the damper-related components, either the switch or motor or the damper door may be binding.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp (and Sharp-made Dacor / Wolf) models stop after 59 seconds.

See the attached sample drawing for a typical damper assembly.

We have the applicable service manual here and the parts list here.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Wolf - microwave oven not turnin ON


This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
