SOURCE: Fan stopped working in JVM1533BD microwave

I assume you're talking about the hood fan which ventilates the cook top and blows air through the grille across the top. If so, it's okay to use the microwave with that not working, but if you boil something on the stove, an external fan is definitely needed to keep mositure from going up into the microwave controls. If the cooling fan INSIDE the microwave (behind the keypad) is not working, then you do NOT want to run it unit it is fixed.

SOURCE: Microwave runs with door open

I would say you have a failing door switch or the mount which holds your door switch is loose or broken. In most designs, it is the upper door switch that will produce these very symptoms when it is intermittent or its mount is broken or loose. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. Slamming the door, damage during shipping or transportation and sloppy manufacturing techniques or materials are the primary causes of trouble with the door switch mounts. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

(If you need more help than this, please reply back with your model number)

It's probably a bad door switch or door switch mount.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

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 only need a switch, you can order one from us for $5 postpaid.

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.

SOURCE: Microwave Oven Does Not Start Cooking

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

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

Door switch or mount trouble is usually 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.

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.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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

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 & testing.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.

If you only need a switch, you can order a universal type here for $5 postpaid.

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

Oven heats, but light, fan and turntable do not come on.


Hi Ted

many microwaves have safety mechanisms to reverse, or stop the turntable if it senses resistance to the turning. This is done both because
  1. the turntable is usually driven by a small motor with a gear reduction transmission to get more torque on the glass platter and your food, and if something resists the turning, it can damage the gear train or belt if it keeps running.
  2. if you have something with liquid in it and it hits a wall, it could tip over, possibly spilling scalding liquid all over and maybe surprising the person who opens the door.
In some cases, it'll just stop and then try again the next time you run the microwave. The banging on the case sometimes turning things back on suggests that either something in the turntable mechanism is awry, or that there is a common hot wire, ground loop, or possibly fuse for the light/fan/turntable.

the manual for the oven doesn't really say anything about this.

You can see generic intructions on looking for an internal fuse here
Panasonic Microwave NN CT552W has no power plug fuse ok Has it got thermal... . Please, in particular, make sure you unplug the oven before opening anything. This is one of those devices where defeating the interlocks and having it turn on can seriously hurt you.

With regard to the turntable, in particular, it's really easy over time for exploded spaghetti sauce, spilled cocoa, and overmelted butter to have run down into the indentation in the middle of the bottom of the oven cavity. Remove the platter. Is it clean in there? Does it look like the 'this person never flosses' picture for mechanical rotors? If so, start with some kitchen cleaner and a washcloth damp (not soaked) with hot water. Let the cloth steam /warm the area a bit, wipe it down. repeat if necessary. If there's a lot of cruft built up there, that could be keeping you on the edge of safety shut-down.

Good Luck!

Turntable turns intermittently so unit will not operate


The turntable fan and light all share the same feed, first check wiring for loose connections the problem though is most likely with the controller

I PUT A POTATO IN FOR 6 MIN. AND AFTER ABOUT 2 MIN. IT SHUTS DOWN AND A MIN OR SO LATER IT STARTS UP AGAIN ,BUT THE TIME STILL COUNTS DOWN AND THE TURNTABLE IS STILL TURNING, AND YESTERDAY I HAD TO UNPLUG...


it sounds like it is overheating. but if only stops for a minute or so dont know if that would be enough time to cool off.When you start it up can you hear the fan running? does it keep running when it shuts down? if it's not running then thats the problem If the fan is running and shuts down when it shuts down then try shaking the door when you start it up the next time or you can try it the first time just to eliminate it being a faulty interlock switch. let me know about what you find about these two ideas.

Turntable won't stop


Sounds like a door switch problem or stuck relay contacts on the control PCB. Do the light and fan run too or just the T/T??

Vent fan runs intermittently, starts on and off regularily


I don't have the manual but there should be a temperature setting for the fan to come on.
