    First we lost heat, then a week later trying to "work" on it it now makes a loud noise, but only in timed mode, not in sensed mode?

    Thank you in advance.

What's your problem? Loud humming noise and will not heat. Is it an easy / inexpensive fix or should I replace the entire unit?


Usually that's a shorted high voltage rectifier diode, but it may also be a defective magnetron.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

(if it's not shorted or burned, it's probably okay)

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

My Microwave is displaying F6 and running when plugged in.


I found a sheet that says to check wiring to main or microwave relay for shorts. If no shorts found, replace control board.

Microwave makes loud noise and does not heat. Smell of light burning


The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

GH7145XFB-1 not heating properly


Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Check your main breaker fuse in your panel/subpanel.

Otherwise if the inline fuse is good and the main power is good, then look at the power supply for the microwave.
