F7 error. Wiring schematic

I have the classic F7 error. I have fixed this before by cleaning the contacts. This time I took the entire control panel out, cleaned everything, and was going to put it back when I discovered I don't have a schematic and I can't figure out where all the various wires go. Normally I am not this stupid but I thought they were better labelled and I thought I had the schematic. Without the color codes, I am screwed. Anyone have a wiring schematic for this oven? Thanks.

    Sounds like a great solution. I will try it. BUT....

    The problem now is that I took out the panel to clean and work on the ribbon cable. I disconnected all the high voltage wires (yellow, pink, etc.) and connectors so I could remove the panel and circuit board.

    I am not usually this stupid but this time I forgot to label where the wires went. I thought it would be obvious and I thought that I had the schematic handy. But I can't find the schematic. I must have taken it out sometime in the past and not put it back. So I don't know which wire goes where so I can't put the control panel back on the oven!

    Does anyone have the schematic that they can fax,email,US mail, etc.? Also, if you have this oven, if you can take a picture of the panel properly connected (i.e., with all the wires connected to the circuit board), I should be able to figure it out from that.

    Any help, greatly appreciated.

    The root cause of most F7 problems is a short circuit in between the
    two segments of the ribbon cable. In cases with a metal touch panel,
    there could also be a short circuit between the ribbon cable and the
    edge of the slot in the touch panel.
    __The solution is the same for
    both problems. Add insulation. My fix which has worked for hundreds of
    cases is to simply place a slip of paper in between the two sections of
    ribbon cable and for metal touch panels, also between the ribbon cable
    and the edges of the slot. Try to work the insulation down into the
    slot at least 1/8". See the attached photo which shows my solution. The
    short circuit is caused by what is known as a dendrite. This is a form
    of corrosion that is quite common to printed circuits. Moisture is the
    primary culprit.____Cleaning the contacts is often suggested. This only
    works for a short length of time. The movement of the cable temporarily
    interrupts the short circuit, but with time it grows back
    again.____Using the self cleaning feature seems to accelerate the
    deterioration of the cable.____Don't worry about putting paper in the
    top of oven. It will not get hot enough to burn. GE places service
    instructions in the top of the oven.____Be certain to turn off the
    power to the oven before opening the touch panel.____This problem is
    the result of a design defect in GE ovens that is common to ovens
    produced since 1998.

    Hi. Cleaning the connection is a short term solution. Here is what is
    happening. You remove the ribbon connector and in the process you are
    moving the cable all the way back to the slot in the touchpanel. The F7
    problem comes from a short circuit between the two sections of ribbon
    cable. The movement temporarily disrupts the short circuit, but it will
    grow back again. My fix prevents the short circuit from returning.

    i got this from a forum of the site

    I worked on one of these recently, exact same problem: intermittent
    F7 error code. I couldn't even get it to do the F7 error while I was
    there. There's a pretty good tech service sheet inside the control
    panel. I followed its procedure for testing the keypad (which was
    nothing more than pressing all the buttons and hearing it go "BEEP!" ).

    But the tech sheet did mention that intermittent F7 problems are
    usually caused by poor connections. So I pulled the ribbon connector
    off the control board and cleaned the copper connectors using a pink
    pencil eraser. That whupped that puppy!

    But then I went out on another service call, same oven, different
    house. The pink pencil eraser trick didn't work on this one so I had to
    apply some of that famous Samurai gray matter. To identify the problem
    on this one, I cut power to the range and disconnected the ribbon
    connector that connected the touch pad to the electronic range control
    (ERC) board. Then I re-applied power and let it sit that way for 24
    hours after which the customer was instructed to call me and report on
    the error code status of the oven. If no error code was reported, I
    knew the touch pad was the problem. If, on the other hand, the F7 error
    code came back, then I knew the (ERC) was the culprit. In this case,
    the error code did not come back during the test period and, using my
    keen, Vulcan-like powers of deduction, concluded that the touch pad was
    defective. I replaced the touch pad and problem solved!

    It's important that you don't skimp the disconnect test because
    there's a big difference in price between the ERC and touch pad. So,
    you want to be right on this one. Ok, after you do this test and
    determine which part you need to replace, come and get it here.

    sorry brother. from my soutions u can know that i have given it from other places.
    i dont have any knowledge about this oven brother.
    also i searched NET widely for wiring manual. but no fruitful results.
    ashamed to feel that i was not able to even grasp your problem. your first post itself describes it clearly.
    but i only made it wrong. sorry. i just tried what i could do.

F76 error code on ge oven

One of the most common problems with GE electric built in ovens is the error code "F7? shown on the display. I've seen it many times before and today I had a service call for the same problem again. The error code "F7" will be displayed along with a beeping sound if the ERC (Electronic Range Control) or "clock" senses one or more buttons on the control panel stuck. It could be displayed in any mode: "cook", "clean" or even more often in the "time of the day" mode. In order to fix it, the control panel has to be replaced. This is a very simple job and you will need just a 1/4? nut driver and a Phillips screwdriver. - See more at:

Getting error code F7

Microwave will not operate (cook). F7 error code appears on the display. Electrical circuit interruption between L1 and Neutral in the microwave inverter circuit.

Possible reasons:
1. Check door, hinge and cavity front alignment and adjust as needed.
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.
5. Unplug the oven for at least 40 seconds. If this solves the problem
A. Check the Cooling Fan for proper operation or blockage
B. Check the resistance of the magnetron thermostat. It should be 0 Ohms, replace if necessary.
6. Check that the control cable to the 1100 watt inverter is properly connected to plug P2 on the display PCB & Adjust or Reconnect
7. If interlock switches operate correctly, replace 1100W inverter.
8. If problem persists, replace control assembly.

Error f7 oven wont turn off

Hello there:
The f-7 error code carries several different possiabities
here are several possiable reasons and the things to check
1. F5 or F6 or F7 EOC (Electronic Oven Control) failure Replace EOC(Electronic Oven Control)
F7 Shorted touch panel Replace glass panel
F7 A = Function pad button stuck or
B = Bad clock Unstick button or
Replace clock assembly (also called the ERC)
Please test each of these carefully ok and if you disconnect the board you may want toclean the contacts really good and then try to reconnect the wires and make sure that they are properly connected ok
Best regards Michael

Error code F7

your problem is with the EOC (Electronic oven control) or touch pad if it is seperate from the control...if the touch pad is seperate...unplug range - access the control panel - remove the wiring/tape wire from touchpad to EOC...plug range back in...leave over night...if f7 code comes back it's the EOC...if the error code clears it's the touchpad...replace the part with the problem...if touchpad built into EOC replace the EOC. Hope this helps...if you have any other questions please feel free to comment again.

F7 error message on GE oven

Send an e-mail to Charlie at for a fix-it that you can try. He explains a possible solution fully with his 'The Dreaded "F7" Error' solution. I actually found his information on another website when I did a web search for "GE Profile Oven F7 Issue". I sent an e-mail to him and he replied with free fix-it information. I am not a repair person myself, but, his instructions are very clear and simple to follow. I did the fix-it at no cost in approximately 10 minutes and it has solved my problem so far.

My oven is also a JT950 and the builder installed it in our home back in 2000. Our F7 issue started about 2 years ago. For a few months, "clearing" the panel and/or shutting the oven off at the breaker panel would temporarily solve the problem. About 1 1/2 year ago, however, the F7 would come on and continually beep. A repairman looked at the oven and replaced the control panel at a cost of $600 (ugh...). That solved the problem until a month ago when the F7 continuous beeping began again. There was no way I was going to pay another $600. for "temporary" repair and I was thinking of replacing the oven. Luckily, I came across the above-mentioned fix-it information and took a chance by following the simple instructions provided.

GE Profile F7 Error Code

I'm not sure what your problem is, but I have the same one. My stainless steel glass top model ?? is beeping all the time with error f7 on all the 4 tem control readouts. I'm guessing this is your problem as well. By turning the temp knobs it will stop, but sometimes restarts later for no reason. Other sites mention a ribbon cable on the touch controls (if yours has it, mine does ) that must be cleaned with rubbing alcohol. You turn off the power, and after unlocking the cable you clean the contacts with an easer and a q-tip w/rubbing alcohol. I don't know if this works but I might try it as the beeping is driving me crazy! The service techs will try and sell you about $450 in parts to fix the problem. This problem apparently has plagued these units for almost 10 years. Seems heat makes the cable get shorts at the contacts.

I HAVE NOT TRIED THIS YET so beware, but I had a short in my microwave and the site helped me fix a $500 control board for about 15 cents ( jumped a short on the board with a small wire!) Hope you get your problem fixed.

F7 error code

Hi Kathryn, I believe that I have already sent you my solution via another route. Hope you received it. Basicaly for anyone else with this problem, it is caused by a short circuit envolving the ribbon cable which connects the touchpanel to the electronic control. The solution varies slightly depending on whether you have a metal or plastic touch panel. If you have a plastic touch panel,you need to add some extra insulation between the two pieces of ribbon cable in the slot where it exits the touchpanel. You need to slip it down as far into the slot as it will go. A piece of paper, a piece of file card, a thin piece of mylar will all work just fine. If you have a metal touchpanel, you need to insulate the edges of the slot as well with paper or mylar. Insulate both edges. If you don't have two sections to the ribbon cable, obviously you can't put insulation between the sections. If you have a plastic touch panel and only one section to the ribbon, you are out of luck. There is nothing you can do except to purchase a new touch panel. Cleaning the contacts is a myth. It doesn't help. Hope this helps. Please let me know your results. Contact me at Regards, Charlie

Holly, the info I have on the F7 states that it might be a problem with the touch panel, shorted matrix or start key. Try unplugging the touch pad ribbon from the main board and cleaning the end with an eraser. See if the error returns after that. back.

GE Profile Oven FTP18 - F7 Code

The F7 problem is usually caused by a short circuit between segments of the ribbon cable connecting the touchpanel to the ERC. Open the touch panel. Insert a slip of paper (yes paper) between the two segments of ribbon cable where it exits the slot in the touchpanel. Try to work the paper down as far as possible. A piece of file card may work better. See the attached photo. If you have a metal touch panel, also add slips of paper between the ribbon cable and the edges of the slot. I have shared my solution with over 795 folks with the F7 problem. Most report success. Cleaning the contacts is a myth. It is only a short time solution as when you move the cable you are temporarily disrupting the short circuit, but it will grow back. The short is caused by what is know a dendrite. It is a growth from the silver traces on the membrane switch conductors. If you want more technical information, contact me at The solution should work for all ovens made by GE including Kenmore as far back as 1998. Don't be concerned about putting paper in the top of the oven. GE places a set of instructions in the top of the oven. Many folks have replaced touchpanels only to have the problem return.
