Frigidaire microwave won't start when door is closed. It looks like the door does not latch properly. It worked 20 minutes ago and last night. How do you troubleshoot and/or fix the switches.

Looks like the white switch that is inside the lower door latch is missing on the top latch. The door does not close evenly.

Hello Scott Noble - If I was in your position, I personally will recommend consulting a certified technician first for an accurate diagnosis. Depending on what part(s) is damaged from the door, the microwave could possibly have faulty switches, door switches, or latch which only a professional can repair.

SOURCE: Our microwave will not cook when the door is

please dont even try this, fix it yourself job!!! yes it is an easy fix!! if you know what you are doing,, but if you dont know what you are doing,,,, well to be blunt,
you could just be finding a fast way of killing yourself!
even with the power plug pulled out the wall scocket and stood on a rubber mat!!! just one tuch across the capacitor and you could very well grow wings!!!!!!!!!!!!!!
do you realy wont to die??? call the guy back to fit a new micro switch in the door lock as its set back deep in side the unit and its a cheep part as well
but just like all fixes,,, its not the parts you pay for,
its knowing how to fit them in that costs you so much
this not knowing could cost you your life???????
play it safe,, please,,

Testimonial: "Thank you for your input! I did not know about the capacitor and how lethal it could be. I'm glad that I asked before attempting the repair! Thanks"

SOURCE: Frigidaire FMCB115GC Microwave Oven wont stop

The only parts that are available for this unit by model number are the tray inside and the feet on the outside.

If you were adventurous and found a way to take it apart and remove the door switches you might be able to match them up at an appliance parts dealer but short of that it sounds like a lost cause.

I know that is not what you want to hear, and I as well do not like being the bearer of bad news.....

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.

The unit normally draws about 13 amps of current when it's running, so it's not unusual for the wires to get warm.

A bad bottom door switch is very common in these units.

Once it's fixed, make sure no one opens the door while it's cooking. That causes premature switch failure.

Tell them to hit the "stop" pad first.

The door on our Sharp R-659Y will not close. I had baked a potato last night & then the door wouldn't latch. The light inside is on and the touchpad are lit, but it's not working.

A lot of times on the sharp microwave they have a series of plastic levers and linkage that have to push up and down to latch your door and close the switches inside if one of the switches inside does not close properly the machine thinks the door is open so it will not allow it to run or heat when you open the door look at the little hooks that are sticking out of the door and try to push them up and down and make sure that they have a spring action to them if they do not or one is loose then that is where your problem is

Microwave turns on when door is open and turns off when door closes

Good Morning friend, thank you for your post!

Based off the information you have provided your microwave will start when the door is open and stop when it is closed. It sounds like a possible issue within your control panel or door latch assembly. I would suggest you reset your microwave which can be done by unplugging it for roughly ten minutes.

If that does not correct the issue I would consult a professional technician to come out and properly diagnosis your appliance. I hope this has been helpful. -Matt

Door latch

see this causes and fix it. God bless you
Open Lever If the microwave door won't open the open lever might be broken. This part can be replaced separately.

Door Spring If the microwave door won't open the door spring may have broken. The door spring is located inside the door and keeps downward pressure on the door hook.

Door Latch If the microwave door won't open the door latch might be broken. The door latch is inside the microwave. The door hook, which is part of the door, engages with the latch to keep the door closed during operation. If the door latch or actuator breaks the door may not open.

Door Hook If the microwave door won't open the door hook might not be releasing properly. The door hook is installed inside the door and normally releases when the door is opened. The hook is made of plastic and will break over time. When this happens it will need to be replaced, it can't be repaired.

Button Spring If the microwave door won't open the button spring might be broken internally. The button spring can be replaced.
Button If the microwave door won't open the button might be broken internally. The button can be replaced.

Handle Actuator If the microwave door won't open the handle actuator might be broken. This is a plastic part which can become brittle over time. This part is connected between the door button and the door latch assembly.

Hello,

Usually, the door lever or hinges is the cause of this type of problem.

But in this case, I don't think the door lever or hinge is the cause of your problem.

I think the door is jammed and only needs some force before is can open or unjam.

Use your hands or a flat Philips screw driver to forcefully open the door. Don't apply too much force. Just apply a reason amount of force that could open the oven door.

Before you attempt to forcefully open the microwave door, leave it for about 45mins to 1hr, after that forcefully open the door.

If the above doesn't help to open the door, please let me know so that I can direct you further.

I wish you good luck.

Regards.












Mine does this occasionally, and it's because the door hinges have got a bit out of line, allowing the door to drop slightly, so the catch mechanism won't quite disengage.
Look along the bottom edge of the door and see if it has dropped lower than the front panel next to it. Try applying a bit of upward pressure on the bottom edge with your fingers, while pulling towards you at the same time, and with your other hand press the release button.

If that gets it open, remove last night's failed meal, open the door fully and carefully force it up a bit at a time, to bend the hinges back to level - keep pushing the door back so it nearly closes, and look at the bottom edge to check on progress. When the bottom of the door looks level with the panel , try closing it fully and see if the release button will open it again.

Good luck!

I have a microwave oven over the range ,brand Frigidaire , model CFMV156DC purchased in 2006 and stopped working , even the lights on the front panel are on when I press the start button it happened just a...

I have exactly the same problem. Everything works perfectly even fan, except microwave table won't turn. I just found out what's the problem... The door for some reason is sitting too low now, even though it is not obvious at all. It looks leveled with everything else, but it's not. Set your Microwave to let's say 30 seconds and turn it on. It will not do anything... but you just gently lift the door (while closed of course) few millimeters and your Microwave will start running like new. There is something wrong with those latches on the door, not touching the microswitches inside the Microwave. Doors must be properly closed in order for Microwave to work. This is due to poorly design. I yet have to figure out how to fix that permanently.

Microwave does not come on.....but when i hold up oven door a little it comes on.

Frigidaire microwave FMV156DSB. Turntable don't turn and no heat. Clock, keypad, light and fan works. The guys above looks like they right about either the door or the switches for the latch. This model does have two switches and a fusible switch. Pushing up a bit on the oven door from the bottom right corner when its closed make mine turn on if you set it to cook. Switches numbered 8(x2) on the schematic has part number 5304440026 $18.05. Fusible switch has part number 5303319559 $30.36. Have'nt changed them because it may be the door hinge is bent since the door latch is made out of plastic. Also looks like a real pain to take apart just to get to the switches. I will try to bend the door hinge to see if it fixes it. "And..now." -- Kirk, "Huh?" -- Scotty, "The doors, Mr. Scott." --Kirk, "Aye. I'm workin' on 'em."
