Question about Microwave Ovens

1 Answer

Have a microwave model NNSA616W, sre 6C37231152 purchased in 2007. Am aware Panasonic has sent memo to distributors to install 20 amp fuse instead of the 18 amp that was in this model when it was purchased. Took the microwave to Nickersons, Russel Ave., St. Catharines and assumed it would be repaired under warranty. After receiving a bill for $56.50 for basically replacing a fuse I rather upset with Nickersons and Panasonic. Nickersons tell me they only repair what they sell. It all boils down to the customer paying for Pansonics mistakes. Any appliances or entaining systems will not be relaced or new purchases will not be Pansonic. I know you are looking after repair problems, but could you please forward this to your complaint department. Thanks, Allan Smith

What amp fuse fitted in KOR6N9RR


Maurice,
Most microwaves take either a 15 amp or a 20 amp fuse. If you still have your old one, it should have the amperage stamped into one of the silver collars at each end of the fuse. Hope this helps!

Panasonic error codes h97 h98


If it is displaying error H97, or h98, this generally means that the invertor(power supply Panasonic part number: Z606YM300BP,) is not functioning. The magnetron may also be faulty.


Here is some more information about the part. The microwave may also have a faulty magnetron. If you are unsure, then you should get someone to look at the unit for you before you go buying parts.

BEWARE... VOLTAGES INSIDE MICROWAVES CAN KILL

Panasonic part number: Z606YM300BP, supersedes all previous versions of the inverter used with the 2M261-M32J This Inverter is now available at a lower cost, it used to be £60.00 plus VAT and delivery trade price.
This inverter is fitted to many of the more recent Panasonic inverter type microwaves such as the NNC596S .Some microwaves such as Bosch and Siemens also use this inverter as they are rebranded Panasonic ovens. These ovens are upmarket models, some include advanced functions such as steaming and are normally well worth repairing.
The inverter as fitted to earlier ovens with the 2M236-M42 and 2M236-M1 is also available.

An inverter microwave oven is one without a high voltage transformer You will know you have one as it is not extremely heavy at one end. This type of microwave uses a high power DC converter, called an inverter, to produce the high voltage and filament voltage required by the magnetron.
If you purchase this item for replacement in your microwave then we recommend that you do this only if you are qualified and aware of the dangers of tampering with electrical equipment.
Failure of the magnetron is common and at times the inverter can fail as well. Sometimes the inverter fails on it's own. If your microwave blows the 10 amp mains input fuse as the cooking cycle starts then you probably need a new inverter. An instruction sheet with basic guidelines on fitting will be provided but please do not purchase this item unless you are confident about fitting it. We only accept returns if the inverter supplied is defective which is extremely unlikely.
If you have one of these ovens that is not cooking then it is worthwhile looking at the magnetron. It often shows signs of distress through overheating.

As well as the inverter failing it is also possible you could also have a defective magnetron,


Good luck and thanks for using FixYa


A FixYa rating would be spot on for this information to you.

I have a Samsung household microwave oven model # SMH8165ST that when plugged in will beep a few times then blink "SE". None of the buttons will work.


Try calling Samsung....
Purchased samsung SMH8165ST in Oct 2009. have had the SE code problem for a few month now. Resetting worked at first. Then the light started flasing on & off along with the beeping...would not reset. Out of frustration I called Samsung. I was told they are aware of the problem & would repair in the "epidemic warranty". Repair man just left. It took him about 15 minutes to change out the keypad. No charge!!

Where is the fuse located?


If the model number is correct, there is a small input line filter board with a 125V, 20 AMP line fuse inside the microwave. Its usually mounted on a small input line filter board at the point where the power cord enters the back of the unit. You will need to UNPLUG the microwave oven and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. I found this illustration at pcappliancerepair.com based on the model number you listed this question under:

http://pcappliancerepair.com/model-display.php


The line filter is listed as item 1420. The fuse will be mounted to this board.

You can purchase replacement fuses at any hardware store. You can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Slow Blow fuses are recommended.

If you have any questions, or need assistance troubleshooting, please post back and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit.

Panasonic Microwave has no power


There is a 125V, 20 AMP line fuse inside the microwave. Its usually mounted on a small input line filter board at the point where the power cord enters the back of the unit. You will need to UNPLUG the microwave oven and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. Searspartsdirect.com has some excellent exploded view parts illstrations you can use to assist you in component location and assembly.

If the model number is correct, the fuse is listed as item 55 in this parts illustration:

There are also a couple of thermal cut-outs listed as items 51 and 52. These can affect the operation of the oven as well, but usually are related to overheating something in the oven cavity. If you haven't overheated the oven cavity recently, its probably the line fuse. (Popcorn and Potatoes are notorious for causing overheat problems).


You can purchase repacement fuses for appliances at any hardware store. Just make sure the rating is the same as manufacturer installed fuse. You need to purchase a 125V, 20AMP, slow blow for best results.

To answer your question about the fuse blowing when the unit is not in use...Yes, this does occur. You may have experienced a minor power fluctuation such as a brown out over the night that could have caused the fuse to blow. Some components are more sensistive to variations in current than others.

Another possibility that I have to mention is roaches. This does not in any way insinuate you live in filthy conditons, or have an infestation. I just need to mention that insects (such as roaches) are attracted to electronics. Especially, where there may be food. Since their body composition is mostly made up of water, if they crawl across an electrical component, they could cause a short circuit and blow a fuse.

If you have any questions, or need assistance troubleshooting, please post back and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit.

Panasonic Microwave NN-T993SF has no power. Was working and suddenly the power went out like it was unplugged. It is not our fuses or cord but something in the microwave itself. Is there a fuse or...


most microwaves do have an internal ceramic fuse either 15 amp or 20 amp the cover has to come off to locate it usually at the top just behind the control board. do not touch the high voltage capacitor as it holds a charge even when the unit is unplugged.

Viking Microwave Model VMOC205SS little over 4


9 amps is approx. correct. Does magnatron make an odd sound when running? If not, you will need to discharge cap then clean terminals with alcahol. Replace diode as well. Should run correctly.If blows again, replace magnatron. Suggest you put a 12 amp fast blow fuse in circuit and nor a 20 fuse.If you dont have a grill or an oven, use a 10 amp fuse.
