Timer counts down but nothing happens

time to replace me thinks 21 years is a long run for anything these days

There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

If the timer counts down and nothing else happens, the secondary interlock switch is bad. This switch completes the cook circuit and this is why it doesn't run. You need an ohm meter to diagnose and find the right switch. Switch failure is caused by opening the door when it is in cook mode. Push the stop button first before opening the door and this failure will cease to occur. BE CAREFUL !!

I would replace the door switches and set up the door gap to 1/8" just enough to alow for a little play.
Setting the door square is acheived by slackening the lower door hinge and re tightening it when the door is square.
Hope that helps.

I have a FNCB115GC Microwave problem. The microwave has a icon on the left hand side of the panel that looks like a opened book on a stand with lines on top. This is best that I can descibe it. The microwave turntable does not move or the microwave does to come on but the light comes on and the timer will count down. I have cleared the microwave and unplugged it with no results. Please help. Thanks in advance.

there is a safty door switch,if that switch is not making proper contact this thing happens.open the microwave look for safty switch and replace it or if you know how to open it then clean it and it should work

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 that doesn't work, leave it unplugged for maybe an hour. Then let us know if the hard reset does not fix it.

you have either a bad keypad or control board.

If you have operation of some buttons and not others its the keypad. if you have no operation out of the buttons at all you have a bad control board.

If you turn your microwave on and it sets and the timer counts down you have a bad interlock switch..

please let me know exactly what your microwave does when you set the cook time

Since the inside light and fan don't come on but the timer counts down, I would suspect first a door switch problem, or (less likely) a problem on the control panel.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid.
