SOURCE: safety function activated

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

You can find links to helpful exploded view diagrams and part ordering help here. I recommend that you bookmark that link to your favorites.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find yours, or if you want to look at it without disassembling the oven, you may be able to download it here.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so with a one-year guarantee.

When I turn the micro on it does not turn nor heat unless I lift up on the door. Seems like door needs to be adjusted slightly


The problem you're seeing is nearly always a result of a safety switch that is not being activated by the door. The result is that the oven thinks the door is not shut fully. Pressing the door closed at the latch or downward from the top opposite of the hinges will usually provide enough movement to activate the switch. One of these methods is what I suspect you are doing to get it to work.

Inspect the prongs on the door. Make sure both are not damaged or broken in anyway. The size and shape are critical for effectively engaging the safety switch. Repair or replace parts as needed.

The switch itself is usually connected to the latch striker assembly or to a switch deeper inside the oven - to the latch itself - to detect its position. The striker assembly is partially visible behind the two openings of the door frame - the two prongs on the door push them down and when fully closed, keeps them down. Since accessing these parts requires disassembly of the oven by qualified persons to maintain safe operation - the oven should be service professionally to ensure that the door is closed completely before allowing the microwave to function.

When I try to use microwaave I get a message DOOR


It seems that the safety door switch which is normally a two pronged LIMIT switch is fault or out of SYNC with the door lock circuit. Now unless the switch contacts and resets the main processor board the microwave output will not be activated - this is a safety feature to ensure that the microwave does not work with an open door and be harmful with the HF on human.
So please remove power, check the contacts on the door switch, replace the switch if contacts are open or realign the switch to contact.
Also check the linking cord to the main board from the switch, check the connection pins.

MIcrowave runs with the door open also


your door switch is mis-adjusted,furthermore the other safety switch on the door should have blown the power fuse in the unit,because by design for safety it produces a short circuit if door opens under operation,so if door was taken off and replaced it was not adjusted properly

GE Advantium Microwave section doesn't work.


The primary interlock switch on my Advantium has failed twice. The replacement part is available at: appliancepartspros.com part no. for my Advantium was AP2622452 and it cost $11.74 + $6.95 shipping.

For what it's worth, my nylon connector and wire covering were also scorched a bit but the last primary interlock switch lasted me for over a year.

Please note that I am not an expert at repairing appliances and that I assume no responsibility or liability for any attempt you may make to repair your own appliance.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

Microwave works with the door open


The top door switch is almost certainly defective or loose. Most likely the latter, and possibly due to a loose or broken mount. Chances are that only the fan and light are on, but it's not wise to take chances with microwave energy, whuch can cause burns and fire. One way to possibly test this theory is to pull up gently on the door and see if it stops doing it. But that's not a foolproof test. A broken or loose mount can be caused by inadequate plastic or improper assembly techniques during manufacturing, by slamming the door, or other physical damage. Bad door switches are usually caused by opening the door while it's cooking instead of hitting the STOP KEY first. I have a helpful text file on door switches with safety tips that will help you. You can find it by searching on Yahoo.com (not Google) for microwave safety.txt Good luck and be safe!
