    Hi Bob,

    I have the same problem (fuse blowing often on JMC 7000). I removed the fuse and connected the wires directly but now my main fuse for MW trips/goes off:-(



    I noticed that it trips or fuse is blown when i push the door relase button/latch. it never happens in the middle of a run!!



    thanks,

    I apparently have this same problem with our M167. The microwave completely shut off, but the main power circuit breaker did not trip. Where is this ceramic fuse located on the microwave? What type is it and where do I find a replacement? Jenn-Air manual tells me nothing.

    You're not going to believe this, but my name is Robert Carl and I have the same issue with a Jenn-Air M167 microwave - just shut down at start-up - i figure there is a fuse in there somewhere but where? I have verified no blown breakers, and plugged oven into different outlet. How do you access the ceramic breaker? thanks

    Never mind - found it, fixed it.

The fuse holder may be loose.

With the microwave unplugged, if you can easily turn the fuse with your thumb & forefinger while it's in the holder, it has overheated and fatigued and should be replaced.

Simply squeezing its terminals together with pliers is not really a good solution.

When a connection is loose, heat results, which eventually melts the fuse internally.

This is usually evidenced by a very tiny ball of solder at the point where the end cap meets the body of the fuse.

You can use a generic holder - it's a lot cheaper than ordering one. The connectors should be 1/4" tabs and it should be rated at 20 amps or better.

You should be able to get one from a home center or local appliance parts store.

If it's not loose, then it may be a failing magnetron or high voltage transformer pulling too much current.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

GE less than 2 year old microwave runs, doesn't heat


The problem you are having is that the magnetron that actually does the heating has gone bad. The fact that everthing works fine rules out any type of bad fuse since there is only one 15amp ceramic fuse in most cases in the unit itself. The magnetron is located behind the control panel on top and has some cooling fins on it. Replacing it if you are a do-it-yourselfer is pretty easy provided you can find one at local electronic supplier or on the internet such as www.mwoparts.com if you would like to see what it looks like. It is held in place with typically 4 screws. It has two to three terminals depending on make and model and age. With everything unplugged it comes off easily enough with no desoldering or soldering to do. There is a High Voltage Capacitor and Diode that could be bad also, but without being able to check it in person it would be difficult for me to tell that they are. In my experience the magnetron is the first thing I replace and have never replaced a capacitor or high voltage diode in the past 20 years. Good luck and God bless.

Need New Microwave


Is the interior flaking the only problem with it?

It can be sanded smooth and clean and dried thoroughly, then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Otherwise, if you want to replace it, I would suggest contacting Jenn-Air Customer Care here and telling them your model number.

They can probably give you the model number of a new "drop-in" replacement.

Microwaves usually have a small ceramic fuse inside. White with metal caps about 1 inch long. You can change it yourself but please follow these rules:

  • Always make sure the unit is unplugged when doing this.
  • Replace the fure with the same type of fuse. Don't use a glass fuse if the original is ceramic.
Other than that, I hope that fixed ya...

Jenn-Air Microwave M169B 11 years old.


You should be able to get a replacement keypad, and that's not a hard job for a DIYer.

If you're interested, post your correct brand and model and I'll give you a more specific suggestion.

(Your post subject says Jenn-Air M169B put it's posted under Sharp R-316FS so I'm not sure which you have).

If it's a Jenn-Air, you can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

You can usually find Sharp exploded views by entering your FULL model number here: http://www3.sears.com (the 3 is correct)

You can order Sharp parts from there or from Tritronics at http://www.wehaveparts.com
