Error code F2


Per the tech sheets (page 8), "F2" error code means "Keyboard failure". Recommended by the manufacturer to replace the touch panel first and, if it would not solve the problem, then the control board has to be replaced too. Not the best recommendation but we have to follow it.

- The part number for the touch panel (aka a membrane switch) is AP3130765

- The part number for the control board AP3130764

Here are the break down diagrams for the Kitchen Aid microwave Model KHMS155LSS4

Code f 7


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. It should cover an F7 error code.

A video is available here showing how to remove a typical over the range control panel assembly in under 5 minutes.

This may help:

F7 Error Code On Microwave Ovens With Inverter Board
MODELS: GH9177XL, GH9185XL, MH9180XL, MH7155XMS, & KHHS178L for example

An F7 error code could be an inverter board failure. Anything else that prevents microwave energy may also cause an F7 error, and must be checked. The technician should perform the following procedure to test for an F7 error code:

1. Check the magnetron.
2. Check the magnetron TCO (it should be closed).
3. Check the 3 interlock switches.
4. Check the harness wiring.
5. Check the electronic controls.
6. Check the inverter board.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

I have chefmate microwave and suddenly stopped working. it is showing 2:50 code on the screen only...it was working fine and dont know what happened to it and touch pad is not working..how do i make it...


HELLO.

The code on the screen indicate electric panel fault resulting from the touchpad malfunction.

The touch pad on your microwave oven acts as the brain of the appliance. It not only contains the buttons that you use to enter cooking settings and times, but also controls the function of the entire microwave. If the touch pad malfunctions or breaks completely, the microwave will cease to function. In this instance, the broken touch pad must be removed and a new touch pad must be installed, to restore functionality to the microwave.

1 Unplug the microwave from the wall outlet.
2 Remove the two screws, located on the front or top of the grill at the top of the microwave.
3 Pull the grill off of the microwave.
4 Remove the mounting screw from the top of the control panel.
5 Lift the control panel up and out to loosen. Look behind the control panel to ensure there are no metal tabs securing the control panel in place. If there are metal tabs, gently rotate the control panel to free the tabs.
6 Transfer the wires from the old control panel to the new control panel one at a time to ensure that the wires are properly installed.
7 Install the new control panel into the microwave and secure using the mounting screw that was removed.
8 Replace the grill from the top of the microwave and secure it using the screws that were removed.
9 Plug the microwave back into the wall outlet.
Thanks.

From a similar model's tech sheet (and yours should have one hidden inside):

F7
Power to magnetron interrupted
1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem.
3. Check resistance of the magnetron thermostat.
4. Check the magnetron. See this file for details.
5. Check wiring to the 1100W inverter and control system. See "Checking Inverters"
6. Check operation of all interlock switches. See this text file. Check door, hinge and cavity front alignment. Adjust as needed.
7. If switches operate correctly, replace 1100W inverter.
8. If problem persists, replace electronic control.
9. Plug in microwave oven or reconnect power.

Microwave Model KHMS155LWH3 is showing a trouble code F-2 What does it mesn?


F2 is saying the key pad has a problem:
See this tech sheet:
https://www.servicematters.com/docs/wiring/Tech%20Sheet%20-%208205612.pdf

The touch/keypad can be found here: (Item 9) BLACK
http://forum.appliancepartspros.com/microwave-repair/19054-kitchen-aid-microwave-error-code-f2.html
I am assuming yours is white but the model number does not cross for some reason to a white control panel. When I cross it to your model it comes up Biscuit color ITEM 3 here:
($122.18)
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5133020&diagram_id=948095#d948095

I would check to make sure that no keys are stuck by rubbing your 1st finger FLAT across the membranes to unstick them and then check inside the unit to make sure the flexible ribbon connector is properly mated to the control board. Inside the unti there is usually a tech sheet inside the cabinet stored in a 4 X 6 envelope that may give you some insight on the keypad error. It should be Item 1 here as far as location only:

F7 ERROR CODE ON GH6177XPS


This is a known problem with this unit, and whirlpool has put out a Service Flash out on this. The reason this is happening is Electrical circuit interruption between the L1 and Neutral in the microwave invert circuit. This has to be addressed by a Tech.

F9 code on mod 721-80869400 kenmore elite


This is usually inverter trouble, but it may be the magnetron, controller, wiring, etc.

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.

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