Not in the normal way you think of an on/off switch but yes it is; and it's so you don't leak microwaves and fry your hand or something. It should be totally shut or you shouldn't use it.

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.

The model number would have helped us give you specific advice, but without it we'll give you generic advice and say it may be a door switch issue.

My Magic Chef microwave tripped a breaker,I found a melted door switch and replaced it, the other three test ok.With the door closed everything works like new. When the door is opened the breaker blow


The only thing I can think of is check to make sure all switches are aligned correctly otherwise you will keep tripping the breaker, I'am certain that one of your switches are not properly in position.

Have a Panasonic Microwave NN-SA616W, when door is closed looks like touch pad works perfect, but when I open the door start to make a clicking sound and the light starts to function intermittently (like...


There are usually three interlock switches in the door mechanism. One is in the power circuit for the magnetron, one is in the relay drive circuit, and the third is a logic input to the controller. Many times the one in the relay drive circuit turns on the oven lamp when you open the door at the same time it disconnects the magnetron relay. If the lamp relay is stuttering irregularly, that door switch may be going bad.

Another possibility (if this happens only when you open the door while the oven is running) is that the magnetron power door switch is stuck in the on position. This is not a safe condition. Replace that door switch ASAP, and get in the habit of turning off the oven before opening the door.

When I turn on my oven for cleaning it shows a f9 problem...could you help me with that


An F9 error code on a General Electric oven indicates that the oven's electronic control system has detected a problem with the automatic door lock. The automatic door lock mechanism prevents the oven door from being opened when the oven is set for "Clean" mode. The malfunction may be a jammed door lock mechanism, a pinched or broken wire, a faulty lock switch or a fault in the control board itself.

Things You'll Need:
  • Ohmmeter or multimeter
  • Phillips screwdriver
#step1

Disconnect power to the oven.
#
Step 2

Open the oven door. Remove three screws from underneath the oven's control panel. Lift the control panel straight up to disengage the mounting pins on the top corners of the panel, then tip the panel toward you.
#
Step 3

Inspect the door lock mechanism. The mechanism is in the lower left area of the space behind the control panel. Rotate the cam on the door lock mechanism to be certain it moves without binding. Replace the mechanism if its mechanical parts do not function properly.
#
Step 4

Inspect the wires that connect the door lock mechanism to the control panel. Check for pinched or broken wires. Check for wires with frayed insulation. Repair wires as needed if defects are present.
#
Step 5

Locate the six-pin connector on the door lock motor on the right end of the door lock mechanism.
#
Step 6

Rotate the cam on the door lock mechanism to the unlocked position. Test the resistance between Pin 3 and Pin 1 of the door lock connector with the ohmmeter. The resistance should be 0. Replace Lock Switch 2 of the door lock mechanism if the resistance reads other than 0.
#
Step 7

Rotate the cam on the door lock mechanism to the locked position. Test the resistance between Pin 3 and Pin 2 of the door lock connector with the ohmmeter. The resistance should be 0. Replace Lock Switch 1 of the door lock mechanism if the resistance reads other than 0.
#
Step 8

Contact a certified repair facility if the source of the F9 code has not been discovered.
Troubleshooting the oven with the electric power turned on is a job for a certified technician.

Do not perform troubleshooting on the oven with the power connected. Personal injury and damage to the oven can result.

MICROWAVE TURNTABLE


Does it turn for just a moment or does it keep turning?

If it's just for a moment, that's normal.

If it stays on, either your top or bottom door switch is sticking or it's door switch mount is loose or broken.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be 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. Other times, 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.

One test that sometimes helps is to gently lift up 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.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

Oven not coming on but timer and lights working


The door switches are almost certainly the culprit - probably the upper one. It may also be a loose mount, or even a loose spring in the hook-like devices on the door which activate the switches. There is a center monitor switch whose purpose is to blow open the fuse if the door is open and the upper or lower switch gets activated. That's why the fuse blew when the screwdriver was introduced - you activated the door switch while the monitor switch was on. I've attached a generic picture which gives you the idea. More importantly, at my Web site, I have critical safety information, disassembly tips, and infomration on checking and replacing door switches.
