You do not state the make or model of the vacuum cleaner. Assuming it has a hose, try disconnecting the hose from the machine. You may find your blockage there.

Micro not heating.

The magnetron is supposed to read nearly zero ohms across the two terminals. You are measuring the resistance of the filiament/heater/cathode of the tube. Activity in the magnetron occurs when the heated electrons are emitted from the cathode, pass through the magnetic field, swirl about, bounce in and out of indentations (vanes) in the tube, and finally land on the plate (antenna). The resistance from the cathode to the plate should be infinite. If not, you probably have a bad tube. Or, if there is continuity between the heater and the case, then you have a shorted tube.

What eventually happens to most vacuum tubes is that the cathode (filiament in this case) becomes coated with a material which inhibits the launching of electrons into the tube. When the flow becomes too low, oscillation ceases, and you have no microwave output. Sometimes they reach the threshold, but do no cross over quickly. Then you have a magnetron that is intermittent for a while.

How do i replace door handle

Open the door and look at the inner door. You'll see a frame about an inch and a half to two inches wide surrounding the window. You'll need a very flexible putty knife of about the same width. The narrow frame around the window is metal. Don't scratch it! Put your blade into the gap just above the window part and slide it (no scratching) along until it hits something. That's probably one of the little "L" shaped hooks holding the frame on. Back the putty knife out a little a GENTLY pry downwards. You should see it pop loose at that point. It will try to pop back into place, that's where a second putty knife or something similar is handy. Once you get a couple of those loose it goes pretty fast. Just keep prying and peeling until it comes off. GENTLY. And, no scratches. Now you can see the two screws holding the handle. Once the handle is replaced, that frame will snap back into place just by pressing on it. That frame cost is about $40.00, so don't get in a hurry.
Good luck.

My Food Saver V3835 will not seal canisters. It seals bags AOK but there appears to be no vacuum generated through the extension tube. We have tried several different canisters and covers. I have also...

The negative pressure is very slight and almost not detectable when using canisters for food storage. Once the system is activated, and allowed to run until timed out, the canister should have pulled all the oxygen from the canister. Foodsaver only canisters are designed for the V3835 for vacuum sealing.

How to Vacuum Package Using Your FoodSaver® Vacuum
Packaging Canister
NOTE: FoodSaver® Vacuum Packaging Canisters can only be used with
a FoodSaver® appliance that has an Accessory Port. Please check your
QuickStart Guide to see if your appliance has one.
1. Place your FoodSaver® appliance on a fl at, dry surface and plug the power
cord into a standard electrical outlet.
2. Place the item(s) to be vacuum packaged inside the canister. Leave at least
one inch (1”) between the contents and the rim of the canister.
3. Wipe rim to ensure it is clean and dry.
4. Place the lid on top of the canister. If the canister has latches, put them
in an upright position so that the lid fi ts on the base. Push the latches
downward until they snap into place.
5. Insert one end of the Accessory Hose into the Accessory Port on your
FoodSaver® appliance.
6. Insert the other end of the Accessory Hose into the hole on the top of the
canister lid. Twist the gray tip of hose while inserting to ensure a tight fi t.
7. Follow the steps for vacuum packaging as outlined in your QuickStart
8. Remove the Accessory Hose from the Accessory Port on the appliance
before vacuum packaging in FoodSaver® Bags.
Allow hot foods to cool to room temperature before vacuum packaging. Otherwise, the
contents may bubble up out of the canister.
How to Open the FoodSaver® Vacuum Packaging Canister
To open, press and hold down the gray rubber button in the center of the lid
until you no longer hear air escaping. This will release the vacuum and allow you
to easily remove the lid.

Microwave has no vent suction

check the filter(s) under the microwave. The normally fill with cooking grease and clog producing less suction. Remove the vent filter(s) and turn on microwave and you'll see a drastic difference. The are replaceable at any home center like Home Depot, Lowes, etc. and are very inexpensive. I hope this helps and good luck!

My microwave just switches off in 5 seconds. how do i trouble shoot it?

check the thermistor on the side of the magnetron tubes body, its usually held on by 2 small screws,it's about 1/2" round and has 2 wires on tabs coming out of it, remove thermistor & wires and clip on ohm-meter and heat the thermistor with a match and see how fast it clicks and the meter goes to infinite from a short circuit which will when in circuit shut power off to the tube it's a type of temperature safety switch for the magnetron tube and it or the tube are faulty, also carefully check the tubes body after operation and cutout and see how hot tube is,it could be the tube going out,but i think it will be the thermistor in the end because if the tube gets that hot that quick it would blow the units fuse due to excessive current draw

that a sign of the times we live in ... fortunatly that kind of failure is rare but its seems like such a waste to just throw things away ... but thats also showing us the power of our technology to make things .. we often can actually make an entire product for less than it cost to repair .. thats not a fault of the product but a tribute to modern manufacturing .. a few advantages in buying new are that likely the product has improved in reliability, efficiency and safety over 7 years .. a manufacturer may not even want their older product to survive forever without safety improvements they may now incorporate .. and there is no profit in a product that lasts forever but there is lots of profit in reputation .. so if there were lots of failures then a reputable company hopefully would try to do something about it .. if there were only a few out of millions then, its a shame, but thats disposable.... considering the complexity of todays microwave ovens its remarkable that they are so affordable .. in fact its hard to believe that such a useful and normally reliable device can be purchased for so little... still it would be nice if a manufacturer provided reasonable service on their products if for no other reason than to reduce pollution ... the cost of repairs is often greater than the highly efficient manufacturing process .. are we willing to pay more for repairs just to save the world .. nice thought but i doubt it .. and if the "toss out" rate is low enough maybe its a moot point .. now even if the thing is burned up there are people with knowlege of those things that can make good use of them ... either for spare parts to repair other units or they may be able to repair yours with parts from another .. if you can find one of those people you can profit .. or if you just donate your old unit to goodwill or other charity then chances are those knowlegable people will find your donations and make it useful again for someone that cant afford new ... the charity makes a little money and there is less waiste .. you get a new improved unit, someone makes a little profit and everyone is happy ... still doesnt it just seem wrong to have so many thing "disposable"

Oven is installed not outside vented. There is

It could be that the filter elements are clogged and need to be cleaned. Remove then from the underside of the micro hood and clean them using a good quality cleaner, such as Simple Green. Clean and allow to air dry before reinstalling.

While the filter elements are out, you can check for obstructions and run the fan to see if it is better without the filters installed.

If there is no noticeable increase in the air flow, it is possible that the exhaust vent baffle was not installed correctly, when the mircrowave was first installed.

Hope you found this Very Helpful and best regards!

I would suggest that you check the manual to be sure it;s set up right.

Then you need to check any filters that are in place.

You should also check behind the grille for any obstructions or dust, etc.

1. Unplug it from the outlet.
2. Remove any screws and unlatch any tabs in the vent grille.
3. Pull up and/or out to remove the grille.

My ge microwave after running for about 3 to 4 minute it shuts down and will not start up again for 30 minutes model # TH903659B JVM 1650 JVM 1651 what is the problem thanks

If the fan comes on when you put the unit into a cook cycle and all sounds normal otherwise, you most likely have a bad magnetron tube. (Google "GE magnetron failure" and watch how many complaints and articles pop up). The tube overheats and trips the thermal relay causing the unit to shut off until it cools back down and comes on.
Very, very common problem on these models although GE will not admit it.
