Unlockmy lg microwave oven


As with most situations, it depends on the model number, but try this:

To set child lock:

1. Touch STOP/CLEAR pad.

2. Touch and hold 0 pad more than 4 seconds. LOCKED will appear in the display window and oven will beep twice.

To cancel child lock:

1. Touch and hold 0 pad for more than 4 seconds. LOCKED will disappear from the display and the oven will beep twice.

I continue to get a message on the little screen that says "F-4" Then it continually beeps day and night! The only way I can stop it is to start the microwave cooking, then open the door to pause...


Hi,

F4 means Open humidity sensor, will occur if humidity sensor is detected as being open continuously over 5 seconds it says to replace the sensor.

This is how sensor looks like :-

Hope i helped you.

My kitchenaide convection oven is displaying the E1 F4 error.


KitchenAid ovens are popular for their classic design and simple user interface. When a problem occurs in the function of a KitchenAid oven, an error code will display on the clock as soon as the malfunction registers in the oven's memory. Each code corresponds to a particular type of malfunction. Most can be corrected by disconnecting the power supply for one minute and then restarting. If the code persists, either replace the indicated part or contact a service center. F0/F1
  • The F0 and F1 codes refer to electrical issues. If the code appears as only two digits, the problem is a transistor failure, so you must replace the electronic range control (ERC). If the code displays four digits, it will read F0-E0, which indicates a failure switching from analog to digital, or F1-E1, which refers to a safety flip-flop. Both problems require the replacement of the ERC.
  • F2/F3/F4
  • The F2, F3 and F4 codes refer to problems with the oven temperature sensor or the keypad. If you see the two-digit F2 code, it means your keypad has shorted and the ERC must be replaced. The four-digit F2-E0 code means that the oven temperature is too high. Test the door lock and the relay operation, and correct as necessary. A two-digit F3 code means an open temperature sensor or thermal fuse, so those parts must be replaced. A four-digit F3-E0, F3-E1, F3-E2 or F3-E3 code or a two-digit F4 code means that either the oven is registering as too hot or the temperature sensor has shorted. Either way, the oven temperature sensor must be replaced.

    Kenmore Gas Range model # 362.75491990 F3 error Oven will not hold temp - error message displays and beeps I Replaced the oven temp sensor same issue Is the control panel bad?


    Hi,

    Many models of the GE microwave have sensors that can detect humidity from the foods you are cooking. This allows the microwave to make adjustments to the power levels used to cook your food. If "Sensor Error" appears, you should either press "Clear" to cancel the mode or leave the food in the appliance longer to give the microwave more time to detect the food.

    Press "Time Cook" to manually enter the time if you receive an error message when trying to use the "Sensor Reheat" mode of your GE microwave. The error message may be caused by the food item being too large or too small to detect.

    these are some other code error that will help you in case of next time.

    1. Step 1 Press "Off/Cancel" (or "Cancel/Off" depending on your model) to clear the error code. Note the code if it reappears.
    2. Step 2 Replace the touchpad if the code displayed is "F0," "F7" or "F10." A function key is stuck or shorted.
    3. Step 3 Replace the touchpad or the clock (ERC) if the code "F1" is displayed. Disconnect the ribbon connector to the touchpad. If no code is displayed after an hour, replace the touchpad. If the code displays again, replace the clock.
    4. Step 4 Replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.
    5. Step 5 Replace the ERC if "F5," F6" or "F8" is displayed. The ERC is the main control unit. "F5," F6" and "F8 are codes that indicate problems in the ERC functions.
    6. Step 6 Inspect the door-lock assembly and circuit if "F9" is displayed. The door must lock when the oven is in use. If the lock mechanism is not functioning or if the detection circuit is malfunctioning, the stove will display "F9."


    jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); NOTE:


    "F3" codes mean your oven temperature sensor has failed or shorted out. The only thing you can do is to replace the sensor.

    Take care.

    Can you tell me what code F4 means? model


    Code F4 means you need to repair the line to or replace the oven temperature sensor. The line typically runs from the display to the back of the oven, you'll have to trace it yourself. The oven sensor should be mounted to the back of the oven lining (Obviously on the inside) by two screws. Disconnect the power from the unit and unmount the sensor to check it, you should have around 1080 ohms of resistance but first you'll have to get that annoying plastic housing of wires through the mount hole and disconnect it so you don't lose it inside the oven. If you don't see screws from the inside of your oven than you'll have to remove the back panel to access them, but this may be a good thing as you don't have to worry about fiddling the plastic connector piece into the oven. You're measuring the resistance from one lead to the other inside that plastic housing, again at around 1080 ohms in a 70 degree environment. If you're way off, or 5 - 6 ohms off, you'll need to replace the sensor. If the error occurs while cooking you can also run the oven hot, turn off and disconnect the power and take your measurements again. If they read the same your wiring harness should be okay and replace the sensor.

    Oh and btw, you'll most likely have to splice the wires to adapt to your new sensor they're never the same.. not in my experience lately anyway.

    What does F4 on microwave display mean?


    This Kenmore is made by LG for Whirlpool. Confused yet? :D

    F4 means you have an open humidity sensor.

    There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

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

    To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

    A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

    But Sears parts can usually be obtained for far less here by entering either the part number.

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

    On the screen it shows F4, and F3


    F4 means an open humidity sensor, but sometimes this error is bogus and can be reset by unplugging the oven for a minute or so.

    F3 on a GE / Hotpoint microwave means you have a shorted keypad.

    If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

    You can usually 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.

    If you would like to have us do this for you, we do that for $39.95 plus part costs.

    Feel free to contact me directly (and please remind me of your model number) for more information & help.
