I doubt that fuse is used for the heating element. If you can unplug the element in the oven, an ohmmeter should show you if it has opened up (burned out) on you. Turn off the 220 breaker in the breaker box before doing this even though there should be no voltage with the controls turned off. (There usually will still be 110 to the top of the unit.)

    Did you check the breaker? There should be a 220 V breaker for just the oven/stove. Sometimes it will kick off and it won't be obvious if it doesn't kick clearly to the center. Slide it all the way to the Off position, then slide to the On position.

    The controller switch could be bad too, or mice/cats/roaches could have chewed through the wiring to the controllers.

    A VOM set to 500 VAC could tell you whether you're getting voltage to the contacts.. connect then turn the oven on.. dangerous stuff if you don't normally do such.

Where is the fuse for whirlpool microwave model number WMH31017HZ07.

The fuse for the Whirlpool microwave model WMH31017HZ07 is located inside the microwave oven. You will need to remove the outer cover of the microwave to access the fuse. Here are the steps to follow:
  1. Unplug the microwave from the power source.
  2. Remove the screws on the top of the microwave that hold the top grill in place. Remove the grill.
  3. Locate the screws that hold the control panel in place. Remove the screws and carefully pull the control panel forward.
  4. Locate the fuse holder on the right side of the control panel. Remove the fuse holder by pulling it out.
  5. Check the fuse to see if it is blown. If it is, replace it with a new fuse of the same type and rating.
  6. Reinstall the fuse holder, control panel, and top grill.
  7. Plug the microwave back in and test to see if the light is working.
If the light still does not turn on after replacing the fuse, there may be another issue with the microwave and it may require further troubleshooting or repair.

Kenmore modle 721.80042700

It may be a blown fuse or a bad thermostat / TCO on the oven cavity or above or on the microwave.
Yours should have a "mini-manual" (technical sheet) hidden either behind the grille or control panel. It is very helpful in locating and testing components.
There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.
Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer 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.
You can download Kenmore manuals and installation instructions at http://www.managemylife.com by clicking the Manuals link near the top center of the page. Then enter your full model number from the tag on the oven on the next page.
A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

Kenmore Model 721.66222500 just suddenly stopped working. No light, no power, no nothing.

I just had same problem happen on a Kenmore Model 721.89940490. I took off top panel and control panel. Behind control panel is a ceramic fuse. I pullud it out and checked with my mutimeter for continunity and it is blown. Since it is 20 years old I will get a new fuse and replace it. If it works good, if not I will have to go buy a new one to put under the cabinet. My contractor that built my house in 1994 directed wired it but I\'ll spend a little extra and put a plug in the cabinet, if I have to replace it. I suspect I won\'t but there is still that possibility.

No panel lights. No activity. Outlet is alive. No symptoms.

It's likely a blown fuse or a thermal cutout / thermostat on either the magnetron or the top of the oven cavity.

Accessing some components (especially the oven cavity thermostat) for testing and possible replacement will require you to remove the oven from the wall and take off the outer 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.

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.

Blown Fuse on a Microwave

You can usually find exploded views and order parts by entering your model number at the Sears parts site.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

There should also 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.

Kenmore microwave model 665.68681891 runs but won't heat

Test the high voltage capacitor, the rectifier diode.or the magnetron. If all this are fine, test the control board.

If it additionally does not spin and no light, then check also the door switch and fuse.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts. (here in UK).

Microwave arced, wont heat now

I'm assuming that it doesn't microwave either. If it does...then the heater is bad. Sears parts sells them. Second guess is a blown fuse or thermosensor. Inside the pad housing, locate the internal fuse and replace it if blown. The thermosensor is a black plastic bit about the diameter of a dime and 3/8 inch thick and clamped to the side of the unit inside the control area. Test it for continuity and replace if open. If not either of these, then you have power supply issues or control panel problems. My bet: the heater blew out. Often, this is caused when you heat greasy foods.
