Question about Microwave Ovens

1 Answer

Microwave Problems Panasonic NN-S541 .... comes on, runs for about 3-4 seconds and then shuts off. Doesn't matter what cycle I choose, I get same results. I do hear some "strange" noises (clicking??) coming from the right-side middle to rear of the oven the short time it's running. Also, I get a VERY faint odor akin to electrical smell. It is so very faint as to make me wonder if I'm imagining ... it's that miniscule. I only paid $100 for it new, so I'm not wanting to take it to a repair shop ... thought there might be something I can handle. If not, I'll buy a new one. Thanks! body { background: #FFFFFF; margin: 0px; padding: 4px; font-family: arial, verdana, sans-serif; font-size: 10pt; } p { margin:0px; padding:0px; } .spwrap { background: transparent url(../wysiwyg_rte/misspell.gif) repeat-x scroll center bottom; } I have a Panasonic microwave oven model NNS532WF and I am also having this problem. Everything works as it should UNTIL you push the start button. When it starts up the clicking sound starts and then after 5 seconds everything shuts down, game over. body { background: #FFFFFF; margin: 0px; padding: 4px; font-family: arial, verdana, sans-serif; font-size: 10pt; } p { margin:0px; padding:0px; } .spwrap { background: transparent url(../wysiwyg_rte/misspell.gif) repeat-x scroll center bottom; } From what I've read, microwaves are supposed to last about 9 years. That means this should be good for a few more years but perhaps that is due to it just being a poorly designed product. I know one thing, I will definitely be purchasing new microwave before I shell out to buy a new inverter to get it repaired. Panasonic has the part available but as you can see it clearly is not worth it. A606Y4T00AP HI VOLTAGE INVERTER 162.58 Especially if you have to pay a labor cost on top of it. I do not think I will be replacing my microwave with another Panasonic one and I will be checking to make sure it is NOT built with an inverter.

    Thank you for your informative post. We went ahead and purchased a new microwave. I did not realize microwave ovens were so dangerous until I read what was posted on this site. That was really helpful since I am a big DIY kind of gal. Thanks again!

If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

It may be as simple as a door switch, but it's usually a problem with your inverter, magnetron, or digital programming circuit.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on the high voltage section.

If you were to opt for service, I would recommend that you contact your nearest Panasonic-authorized servicer.

Child sign in window of microwave ,cant start it panasonic


On my NN-L738BA there is a Child Lock feature.
You set the child lock by pressing the Start button 3 times.
If the Child Lock is enabled it displays the word :CHILD".

To disable this feature on my microwave the manual says to
press the Stop/Reset 3 times.

Check your manual for the Child Lock.

Microwave Problems


Thats exactly why so so many repair shops have closed their doors mOH NO not because of you!!!lol its because of items are made to last a year or so and they are so inexpernsive theythrow them away and simply buys a new one cause for 100 bucks who can blame ya. your problem should be looked at by a pro unless you know how to deal with electricity and charged capacitors. it will run between 15 to 45 to check out the unit and probably cost about 50 to 100 bucks if not more to fix see my point? Buy A new one. Good Luck .

Microwave Problems


Panasonic NN SD696S (SS) popout knob style (Costco): Clicked off; first occasionally, then frequently, then always after couple seconds (click from relay on circuit board behind keyboard). Checked fuse solution--too sad--not the problem. Checked Fan and various areas with VOM; then noticed browning of the two connectors on micro-switch by door-interlock?. Switch (marked Omron V-15G-3C25, 15amp, 125-250VAC). Inside points showed bad arcing, hence the heat to char the connector insulation. Bypassing the switch, the microwave works fine--Eureka!--which will do until replacement. Found Grainger has (w/o min quantity of 100), for $2.21 (2KRF8)--hope to pick up one Monday. Switch is kept in place by two plastic "toothed" fingers--should pop right back in if dimensions prove to be identical.
