I have a 13yr old above-range oven which quit when my wife cooked food in an aluminized foil wrapper (a small fire ensued!). This oven has 3 thermal protection units, on the magnetron, the chassis and on top of the food cavity. This last one had failed open, and since it's in series with the magnetron thermal protection unit and the main relay, nothing would work. MAT electronics sell the units for less than $4, but my problem now is to pick one with the appropriate temperature cut-off. They range from 200 to 300F.

"EE2" is magnetron (2) failure, but it doesn't necessarily mean the magnetron is bad.

It simply means that the reading sensed by the current transformer is incorrect.

It could be the magnetron, HV transformer, rectifier diode, HV capacitor, door switch, or relay.

I have uploaded a similar service manual to my site. Bear in mind your parts number may vary.

The 22 seconds is the giveaway.

In most cases, this is a problem with the inverter or 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.

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.

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 the mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

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.

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:.

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.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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.

Code ee 5 on sharp microwave model rcd 2200m


It may be that the voltage selector on the back of the oven is not set to the proper level of your AC supply.

It will probably have settings for 208VAC or 230VAC.

Chances are your oven is set to 208VAC but it is on a 230VAC line.

Refer to your owner's manual for specific details.

I have a sharp microwave sometimes it works for 10 or 20 seconds and then stops with error ee2, other times it works fine. Today it did the same but stopped with error ee1!


This sounds like a keypad problem, sometimes a short developes in the keypad controller causing all kinds of intermittent problems, on the back is the microprocessor circuit board which controls vital areas of the microwave oven. The cost to repair will be high and consideration should given to looking at a replacement.

The microwave screen says EE2


The fault code "EE2" on a Sharp commercial microwave oven means that the magnetron 2 circuit has a problem and is pulling too little or too much current.

It may be the magnetron, high voltage transformer, high voltage diode, wiring, etc.

Since you didn't mention your model number I can't say for sure, but magnetron 2 is usually the lower magnetron in a Sharp.

You can order Sharp commercial microwave parts here.

If you need more help, we may have the service manual for you to download free.

But we would need the model number.

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

So to allow us to help you effectively (at no charge), please post a
NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit and your symptom, "EE2" code.

It may be a shorted high voltage diode.

Since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

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
