Microwave Ultrawave with Hood fan

I have an Elite Microwave Oven/Hood Fan Ultrawave, Manufactured by LG. My kitchen timer will not work on 20.00 minutes and show the error F4. Also my 5 speed fan will only work on 1 speed. Could both of these need a new oven temperature sensor? Thanks, Marjorie

You are right. f4 means shorted oven temperature sensor (RTD). Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

Have a TE code showing on my kenmore elite microwave hood combo


At some place I saw that the TE error refers to the touch panel.
If you go to http://www.searspartsdirect.com/ and enter your full model number you can get parts list and buy parts and even get repair advice.
Link below shows how to replace a control panel on some model of microwave oven. In the video you will see a ribbon cable being removed. You might want to wipe the contacts of the ribbon with alcohol and put it back in to see if it helps with your problem.

Kenmore Elite Microwave oven 63792 doesn't heat - all lights, turntable, fan, etc. work just fine.


Most likely it would be a bad magnetron since the light, turntable, and vent fan are running.

you can take it into a local repair shop but it might cost more to repair it. Looks like you can replace the unit for 150 to 250 sears carries this brand.

Light, fan and timer work but microwave does not


Microwaves are pretty much a non repair item. It will cost you more to fix than it would to replace.
