I have a Panasonic Genius inverter microwave, at least 10 years old. Stops running after a few seconds, and there is a burnt plastic smell. Worth fixing?

That depends...

It depends on how much the repair will cost and how long it will be before another repair is needed - these are unknown quantities but you could ask your local repair shop and a Panasonic dealer how much for a repair estimate.
Mostly if you go ahead with the repair the cost of the estimate will be waived. If you don't go ahead you should be able to negotiate the estimate cost as a discount off a replacement - if you use a Panasonic dealer.

10 years of hard work from a premium microwave should be as nothing when you consider my old Sharp Carousel lasted me 29 years of daily use, but then things today aren't built as well as they used to be.

I suggest you decide on the cost of a likely replacement model before you go ahead, follow the link below to begin your search. In the final analysis a repair is a bit like making a wager while buying new with a warranty is like putting your money on the favourite...

SOURCE: Microwave turns, gives out strong burnt plastic smell, little (or no) heating

I would first suggest that you look inside the cooking cavity to see if your wavegudie cover is burned or carbonized. If so, it will need to be replaced. You can order one via Tritronics at http://www.wehaveparts.com The job of the waveguide cover is to protect the waveguide (opening) and the magnetron from buildup of food particles and grease. When the grease and food particles build up on and behind the cover, they will carbonize and arc - and maybe even flame up! The solution is to clean it and keep it clean - but if it's too dirty or is burned, it must be replaced. Sometimes it's necessary to remove the cover to clean both sides of it, and to clean the edges of the opening it covers. It is sometimes held in place with a small plastic rivet (or screw) and once that is removed, the cover will slide over a little then drop down. Be VERY careful not to get cut on the potentially sharp edges of the opening, and do not spray anything into the opening. Apply an alcohol-based cleaner (such as the purple kind) and /or gentle scouring powder to a cloth or paper towel and carefully wipe it out, then when it's dry, reinstall the cover and the rivet. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. Once you remove and / or clean the cover and clean the opening of the waveguide, if it still won't heat and/or still has the smell, you may have a bad magnetron or high-voltage transformer. Feel free to post back if you still have trouble.

SOURCE: buzz, plastic smell and no heat

Chances are you have a magnetron that's failing. GE had a rash of "underperforming" magnetrons on these units. They replace the magnetron, stirrer and high-voltage diode at no charge for parts as long as a GE-authorized service center does the work. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. The bulletin shows you where tyo check. To see if yours is covered, see this bulletin: http://www.microwavedisplay.com/ge_mw_mag_kit_bulletin.pdf Otherwise, you need to contact GE Customer Relations at 1-800-386-1215 as soon as possible and tell them your problem and they will put you in touch with a local authorized servicer.

SOURCE: scrape or fix? Panasonic inverter genius sensor 1250 watt

In most cases, this is a problem with the inverter but it may be a bad magnetron.

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

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

SOURCE: Panasonic Inverter NN-V673S microwave- shuts off after 2-30 secs

If the screen is showing a fault number or a number you havent seen before then its probably a program fault which can't be fixed. Check that the vent holes on the back of the oven aren't dirty and ensure that the whole oven is clean inside. Sadly it sounds like a program fault which cant usually be fixed by the owner though.
Finding a Panasonic oven repairer in the UK shouldnt be a problem though. My parents had a simlar problem wth their Panasonic Inverter oven, called the UK customer services and Panasonic contacted an authorised repairer in Scotland to visit them. Call customer services on 0844 844 3868.
If the call out charge exceeds £80 then you're probably better off buying a new oven.

Panasonic 1250w genius senor inverter less then a year old. Control panel lights up, works.microwave itself does not, control panel shuts off in a few seconds

When a Panasonic Inverter Microwave shuts off after a feew seconds, it is either a bad inverter which is the quite expensive circuit board that powers the magnetron that puts out the microwave energy, or a bad magnetron, Or BOTH typically this would be a costly repair, But since it is still under warranty. You need to find a Panasonic warranty service provider in your area. If it is a counter top unit, you may have to take it to them for repair.

Panasonic genius 1100w inverter microwave stops after 23secs.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

1200 watt panasonic genius shuts down

If it stops after 7 seconds, it has a problem with the inverter.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

Display codes H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.

That may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

Microwave shuts off after 3 seconds

Although your model number doesn't seem to show up, the NNS950-series units are powered by an high-voltage inverter. And yours has failed. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Sometimes a whole new inverter is cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized appliance / microwave repair shops and ask then specifically about inverter component-level repair and simple inverter replacement costs for your exact model number.

Microwave shutsdown after 24 seconds, does not heat up

Classic symptom of a defective inverter. It it's under warranty, you're probably in luck. If not, expect repair costs of about $120-150. If you can find a servider who will repair the inverter instead of just replacing it, you can save some money. If you or a friend can replace it yourself, you'll really save, assuming you follow safe procedures. You can find my file "safety.txt" via a Yahoo search. It is part # A606Y5X00AP for model NN-T993S and runs $62.83 plus shipping. The inverter can be gotten from Panasonic at http://www.pasc.panasonic.com/epartr

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.
