    by the way, the Guest response above was me i didn't realize i wasn't logged in.

    ok, i had ordered the thermostat (fixed) and it was open, thus bad on the advice of my friend, and replaced it last night. the first time i tried the microwave it worked but kicked out an F3H error with a pic of 2 water drops. which i'm assuming is the humidity sensor. on the 3rd time i used it ran for a couple of seconds and it went back to the F7 error.

    i read above that F7 means a control pnl issue, all keys seem to work fine when pressed. when you press a button it beebs and displays whatever the key should do.

    one last thing, i noticed a 3 pin connector just hanging in the control pnl area, but there are 2 different plugs on the back of the control pnl. the wire comes from the top front and goes to the left side front and disappears in the cabinet. which plug should it go on the control pnl, if at all?

    sorry, but the camera i have access to shows a good pic, but its over 1.5 mb and this site has a limit of 150k. is there some other way to get the pic to you?

  • djsdink Mar 13, 2008

    ***** sorry it was late last night when i posted my last comment. i didn't mention that there are not the standard looking resistors. there are three squareish looking components, one, is larger than the other two. they are aqua blue in color and the print is gray and too small to read. i didn't have a magnifying glass. they are close to one of the plugs. i cannot tell if they are a capacitor or resistor. i tried to shrink the pic to a smaller size, but don't have a software program to do that. the pics were to small to get the plug and the things around them.

    i hope you can see this.

    Normally fault code F7 is a sticking key or your keypad.

    You say it runs - do you mean you start cooking, then after a couple seconds you get this error?

That loose cable sounds like it would be the humidity sensor. They're usually a shielded cable with three pins.

It will usually plug in close to a large resistor, like on the Sharp shown below.

Probably on the upper (display / control) board but I won't wears to that.

If you don't find it, please post a few photos of your board.

The symptoms - on hi it would run for a couple of seconds then shut off with the error code f7. on a lower power setting it would run but not heat.
i had a friend look at it on sat and he said it was an open hi temp sensor. i took the part to an appliance parts store and they looked it up and said it was a thermostat, i should be able to pick it up on monday after work.

No power on microwave model #gh9177xlb-1

follow this steps and fix it. God bless you

  1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

Instruction book in English for Family Chef model FT 338 Purchased in France this week by English family.

It seems there is no English language instruction book for the Wirlpool microwave FT 338. However, the nearest UK equivalent is the FT 337, and the only difference is the lack of the "Crisp" plate.
I suggest you download the FT 337 instruction book in English from the Wirlpool.Uk website, and also the FT 338 insytruction book in French from the same source, which means you only need to translate a few lines of French into English to have the full instructions.

Model 72180883400

F-9 error code indicates a defective control board, inverter or line voltage too high. f the microwave runs for about 7 seconds with a ticking sound..then stops and shows "F-9", it is the magnetron that has failed. The fact that the unit starts and runs with the TICKING SOUND means the control board is sending signal to inverter board and the inverter board is sending signal to magnetron. Magnetron is covered by full 5 year warranty, inverter board is only 3 years.

GH7208XR Error Code #7

Behind the right front corner faceplate is a bag with the tech support info.
I used this and went through all the troubleshooting and got to the power inverter board. This board has the 2 red wires out of it that go to the magnetron. Instead of replacing the whole inverter module , I examined all the components on it. I found that there are 2 high voltage rectifier diodes attached to the transformer and 1 of them was not testing good. The diodes are UXC2B diodes.. Just clipped out the bad one and soldered in a new one.
Hope this helps..
