Was working then everything went dead


If after a reset, at the household circuit breaker box, does not prove to be successful, sounds like you will need a new control board and a full diagnosis to make sure the board did not short anything else out internally. This is not a typical DIY job, so I would recommend a technician complete this for you.

Hello,i have microwave KHHS179LSS-2. Display indicate code F7. I check magnetron thermostat resistance is 0 ohms. I replace 1100W inventor. Microware stil indicade code F7. Thanks for you help.


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.

You can find helpful exploded view diagrams and order parts by entering your full model number (KHHS179LSS2 without dashes or spaces) from the tag on the oven here.

What is the F7 code mean?


According to the technical sheet found hidden inside the unit behind the controller and online here:

F7 Power to magnetron interrupted
1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem. (Possible reason: Over temperature protection for the magnetron opened.)
3. Check resistance of the magnetron thermostat. It should be close to 0 ohms.
4. Check the magnetron.
5. Check wiring to the 1100W inverter and control system.
6. Check operation of all interlock switches.
7. If switches operate correctly:
- Replace 1100W inverter.
- If problem persists, replace power supply board.
8. Plug in microwave oven or reconnect power.

MY KENMORE 1000 WATT LITERALLY WORKED FINE ONE MINUTE THEN NOTHING THE NEXT. I HAVE NO IDEA WHAT HAPPENED.


Most likely the circuit breaker tripped or the fuse blew. A 1000 watt microwave is using 2/3 of the power available on a typical household circuit of 1500 watts. If anything else is plugged into that circuit u can have a problem. Just reset the breaker or replace the fuse and u will be up and running. if it happens alot you should consider a dedicated circuit for your microwave only.

New Microwave not working


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If it's still not working, you'll need to contact your nearest Panasonic-authorized servicer.
