Microwave error code

I have a Sharp W/R - 23 1900W microwave which has started displaying ERR 2 and ERR 4 codes. Machine still works but have to stop and start when these come up. Is there an easy fix or an expensive one.
Thanks

    Hi and thanks. Yes its an R-23AM.
    The code is EE2 which i believe is a problem with the Magneto.
    If it is do you know if it is an easy self repair or should i get someone in - have seen magnetos advertised for aprox £80 which will probably be double through a service company.

    Only thing stopping me doing it myself is all these BIG warnings about discharging the capacitor.

    Thanks again
    Guy

    Could you double-check the model number tag on the unit?

    I assume it's some R-23 variant?

    And the codes - are they ERR2 and ERR4 or EE2 and EE4?

    Happy to help, I just want to be sureI have accurate info.

    Thanks.

EE4 means the line voltage is too high. Usually this is fixed by resetting the voltage selector on the back.

The voltage selector may not look like a switch, looking rather like a metal panel that has to be taken off and reoriented. There will be a label next to it indicating a voltage number.

EE2 actually means that the control circuit senses that magnetron number 2 is not running.

It doesn't necessarily mean a bad magnetron.

This can be due to a bad or misaligned door switch (common), a failed relay (#3) on the control panel, or a failed high voltage component such as transformer #2, capacitor #2, rectifier #2 or magnetron #2 or loose connections anywhere along the chain.

We have a similar model's service manual on our site. Please not that yours may be different! Part numbers will probably not match. But it will help with safety, disassembly, discharge and diagnosis.

I have have a 10 year old Kenmore Hood/Microwave combo built by Whirpool. I'm getting an F6 error code. What is the error code trying to tell me?


F6 —Microwave Relay Failure: Check the microwave relay.

The F6 error code which is flashing on your microwave refers to a faulty relay. However, I would suggest that you first try to run a diagnostic (which you may not be able to, but it is beneficial if it works). Here is how:

The microwave oven may be provided with a self diagnostic routine that can be operated through the touch pad keyboard. To enter the self-diagnostic routine:
1.While pressing the CANCEL keypad:
a) Open the oven door.
b) Unplug the microwave oven for 2-seconds and plug it back in.
c) Release the CANCEL keypad and close the oven door.

NOTE: The humidity sensor test results will appear on the display after 8-seconds.If the tests are successful, "OK " will be displayed. If one or more of the tests fail, "ERR " will be displayed.. 2.When a keypad is pressed, a number according to the test chart will be displayed. When no keypad is pressed, a blank "—" is displayed.
If you want to try to fix it your self, Always remember Electricity is dangerous and should be treated with respect.
Microwaves are very dangerous, they can still shock you even unplugged!!
Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it. With the microwave unplugged.

Hope that helps.........

Microwave not working stating error 3 or error sensor or just coming on by itself. we have tried shutting down circut breaker


Hello

"ERR 3" means that the magnetron units have failed in the microwave. Food will not cook or heat up when the microwave is in use.

This code is different than "ERR 1" or "ERR 2" because with those the microwave is still operational. "ERR 3" means a complete failure.

The magnetron is the main source of power and heating in a microwave. Magnets work inside a magnetron tube to create the heat and voltage needed to cook items.

Bring the microwave back to the retailer or a repair shop for service. You may also consider purchasing a whole new microwave if the prices are cheap enough.

Jenn Air Microwave Error Code


Hello Hec1152,
I have found the manufacturer contact information for you, but could not find information about the error code. If everything works fine, but the microwave is not heating your food, then the problem is most likely the magnatron or one of it's components, which sadly to say is the most expensive part to replace. Please feel free to contact the manufacturer via phone or live chat to get more details as to what the error code means.

If you would not mind, could you please rate my help. I would greatly appreciate it.

Is that code actually "EE3"?

If so, that is called a Magnetron (1) and (2) failure, but it may not be the magnetron.

It may be any of number of things, form door switches to control board relays to the high voltage parts.

Methodical troubleshooting is needed, and we have the manual for similar models here.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

I found the fix to the F3H error on another site. Just turn the power to the microwave off for ~2 minutes at the circuit breaker, and then turn it back on. Microwave will start working again then.
