No... you are not in a microwave induced time warp...
Your microwave oven needs a "reboot". The same thing happened to me.
Unplug your microwave oven, wait about a minute (more or less), plug it back in. Try setting/running your kitchen timer, boil water, etc. Your timer software on the microwave should be reset.

The fan may be on when the door is open but the oven is not generating microwaves at that time. Replace defective microswitch.

Bad door switch, look at the wires going to the switch and see if any look browned or like they were hot. Make sure each switch clicks when you push the plunger down and release it. I always replace the switch with one that has 1/4 inch terminals as they hold up much better then the ones with the smaller 3/16 terminals. Just beefier and better.

The problem with turntable motor or coupler which sits on turntable motor shaft. I’m happy to help further over the phone at https://www.6ya.com/expert/vitaliy_f406165329c75ede

Make sure no metal item (forks-spoons or oven rack) is touching the outer wall of the microwave. That will cause sparks. If all that is OK then there is usually a metal fan type blade in the microwave top called a stirrer blade that may be out of place and rubbing the cavity causing sparks. Try to pin point the spark area so you know where to look for the problem. Sparks usually mean metal is touching metal somewhere.

I agree that the cost of the repair outweighs the cost of replacing the whole MW. It appears that the solid state device that takes the keypress from the keypad to control the light circuit is shorted so the light stays on all the time. Most likely from a lightning surge. Use it the way it is. You will hurt nothing without a light in the socket. My info indicates this is a model from the late 1990's so it is about 15 years old. It is not hard to changeout a microwave. You might need some help lifting it into place. Choose one as similar as possible to the old one.

Probably not cost effective. Your measurements suggest a standard size microwave. Take them down to a big box store and compare with models on display. note where the plug comes out and whether you have a vent or not. Most can be made vented or ventless when installing.

Spray the inside with Dow Scrubbing Bubbles Bathroom cleaner, let foam, wipe clean, and rinse. Then if the odor persists, mix one part vinegar, two parts water in a bowl, set inside the Microwave and turn on for five minutes.

if unit won't heat, then there is a problem with either the magnetron or the diode. if its the magnetron, the microwave will sound almost normal. if its the diode, it will make a humming sound

After 16 years, I should think you had your money's worth from this machine.
There are a few arguments for fixing it, if it's repairable, but a new one will be more powerful while being more efficient too. (use less electric)
Less radiation leakage too.. (pacemaker exposure?)

Perhaps you should first try shopping around to see if you find one that you like, and that fits in the space you have for it, etc. If you buy a new one, get a good one. Don't go cheap.
If one seems to make good sense to you, then buy it. If nothing looks good to you then find a repair shop to take old one to.

Why would you keep old one? Well first of all, they don't make them like they used to. Lot of new ones are noisy and rattle a lot. Don't last nearly as long. Many new ones have problems early.

Old ones are lower power, which is slower, BUT food heats more evenly because of it. Less prone to exploding food.

Hi,

When the microwave lights don't work, the problem is either the light bulbs, or the relay on the display control board. If you've already replaced the light bulbs and that didn't fix the problem, the relay is shorted and the display control board will need to be replaced. It's very common for the relay on the control board to short out when the bulb does because the relay is very weak. The only fuses on this microwave cut out the entire display and all the lights. There is absolutely nothing between the control board relay and the lights other than wire.

You just unplug the microwave, then remove the screws going into the top plastic vent grille. Remove the vent and that will expose a screw at the top of the control panel. Remove that screw and the control panel will pull up and off. That will allow you to access and replace the control board.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The door handle can easily be replaced on MOST microwave ovens by removing the inner door panel that goes around the perimeter of the glass. The following link explains how to access and replace the door handle:


http://www.fixya.com/support/r3696942-microwave_oven_door_handle_replacement


The average cost for a replacement handle usually runs about $20 - $40. Replacements may be purchased at the websites listed in the link I provided.


If you have not purchased a new handle yet, the part number is 4359474 (Black) and 4359473 (White) and costs about $30.


The door handle is a simple repair that can be done with the door in place, or with the door removed. You do not have to uninstall the oven if this is an over the range model.


NOTE: If you wish to remove the door, all you need to do on most models is open the door all the way and lift straight up at the hinges.


If you have any questions, please post back and let me know. I hope this helps you.

The fuse inside the m/w has blown. Remove the cabinet and replace it with the same type and amperage.

your magnitron has gone out

Um, no. You can get a new microwave that is much, much more efficient for a fraction of the repair cost.

hELLO THERE :
the door locking mechanism has a switch on it that senses when the door is closed or open when this switch is failing it will give this sort of a problem
so you would have to replace this switch and make sure that the latch is really cleaned ok
