Door catch is stuck in unit so door won't close and microwave won't work


No, the only way is to take it to a technician. The door and catch has about 4 safety interlocks to stop you getting microwaved. The case has security screws only the techs can undo.

Door will not stay close


Not much data to go on here. The latch on the door has a spring that holds it down in the locked position. when you pull the handle the latch goes up and you pull the door open. You will have to take the door apart and see if the spring broke or the plastic tab that holds the end of the spring is broken.

Remove the cover. You should be able to access the two latches and release them. Once open you will have to take the door apart and repair the latch

Ok.Agreed,latch is not cracked or worn out.But check the grip of latch.Open the door.The hold the latch in your hand and see,if its loose or tight.It should be tight.Press the latch towards down and move it left/right slowly --- slowly.And inspect the latch.It will move,there will be a moment but the position of the latch in the door frame should be tight.If you feel that latch is got very loose,then the door frame needs to be disassembled and latch assembly has to be repositioned and fitted.In most of the cases this latch breaks/cracks and it needs replacement.But in your case,its different,you mentioned that if you keep your oven door pressed then latch remains closed..So if latch is broken/cracked it will not get closed properly.So as per that i think,you will have to check the opposite side of the door frame,where this latch gets into.On that side,there is a interlock type part.Which holds this latch.That part is operated by spring.If in-case that interlock type part or the spring,any of this is got loose then latch will get released after few minutes.--------------- But first as regular troubleshooting,you inspect the latch.Do you feel its loose or getting very easily moved,then open the door frame and check the latch.----------- For that you will required door disassembly diagram:--- Click the link,see part number 3 is door latch.-------- http://www.searspartsdirect.com/partsdirect/partsdirect/showSubComp.pd?imageUrl=http://c.searspartsdirect.com/lis_png/PLDM/W0505176-00002.png -------------- If the latch is properly positioned and intact then ,you will need to disassemble the opposite side cabinet to check the internal part,which hold the latch.For that you will require complete disassembly:---Click this link for complete disassembly:-- http://www.searspartsdirect.com/partsdirect/part-model/Kitchenaid-Parts/Microwave-Parts/Model-KHMS155LSS2/0593/0123370?pathTaken=&prst=0&shdMod=KHMS155LSS2 -------------- The door latch itself or other parts holding the door latch,none of the part is costly then $10.The cost of part is under $10.---------It just require you to figure out,either is cracked /broken part or just loose misaligned part.-------- This will help.Thanks.Helpmech.

Won't whut off when open door


The microwave running with the door open can be dangerous.

It's most likely the switch in the door stuck in the closed position. Or it has failed/broken in the closed position.

Sometimes the switch is just a button sticking out of the cabinet where the door pushes on it when closed -- sometimes the door latch pushes on a switch inside the latch receiver in the cabinet.

If cleaning around that switch doesn't solve the problem, you should take it to a repair shop.

The closed door doesn't always hit the limit switches


I strongly suggest that you do not attempt to adjust the hinges.

The door switch mounts are either cracked or need to be adjusted.

Door switch mount trouble is usually caused by slamming the door.

This may be a little more info that you need and it's from a Sharp service manual, but the general principles apply:

1. Disconnect the power supply cord, and then remove outer case.

2. Open the door and block it open.

3. Discharge high voltage capacitor.

If the door sensing switch, secondary interlock switch and monitor switch do not operate properly due to a misadjustment, the following adjustment should be made.

4. Loosen the two (2) screws holding latch hook to the oven cavity front flange.

5. With door closed, adjust latch hook by moving it back and forth, and up and down. In and out play of the door allowed by the upper and lower position of the latch hook should be less than 0.5mm. The vertical position of the latch hook should be adjusted so that the door sensing switch
and secondary interlock switch are activated with the door closed. The horizontal position of the latch hook should be adjusted so that the plunger of the monitor switch is pressed with the door closed.

6. Secure the screws with washers firmly.

7. Check the operation of all switches. If each switch has not activated with the door closed, loosen screw and adjust the latch hook position.

After adjustment, check the following.

1. In and out play of door remains less than 0.5mm when in the latched position. First check upper position of latch hook, pushing and pulling upper portion of door toward the oven face. Then check lower portion of the latch Figure C-3. Latch Switch Adjustments hook, pushing and pulling upper portion of door toward the oven face. Both results (play in the door) should be less than 0.5mm.

2. The door sensing switch and secondary interlock switch interrupt the circuit before the door can be opened.

3. Monitor switch contacts close when door is opened.

4. Re-install outer case and check for microwave leakage around door with an approved microwave survey meter.

Door-activated power switch is loose and/or has a short


Fixed this problem! The door latches were greasy and sticking in the closed position (i.e., pushed down so not latching and engaging fully when the door was closed) and this created the problems described above. Solution was to squirt some Windex into the latch holes to dissolve the grease. The switches popped back into position (must be spring-loaded) and the door closed and latched properly, allowing the oven to function properly. I swabbed out the hole with a q-tip, let it dry for 20 minutes and all is well.

Do you test your commercial microwaves for leakage? What standards do you comply with as far as allowable leakage?


As per a similar manual:

1. Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven should not exceed 1mW/cm2 at any point 5cm or more from the external surface of the oven, measured prior to acquisition by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm2 at any point 5cm or more from the external surface of the oven.

2. Safety interlock switches: Primary interlock relay and door sensing switch shall prevent microwave radiation emission in excess of the requirement as above mentioned, secondary interlock switch shall prevent microwave radiation emission in excess of 5 mW/cm2 at any point 5cm or more from
the external surface of the oven.

You need to be sure that if the meter comes with a styrofoam cone tip, that should be installed or it will give high readings.

Also, the meter should be calibrated periodically, typically annually.

If the meter gets dropped or bumped, that may throw it out of alignment.

The most common causes of excessive leakage are loose or misaligned door switch mounts or hinges and physical damage to the chassis of the oven.

The most common cause of the misalignment of door switch mounts is slamming the door.

I would be sure my meter is set up and calibrated, then I would be sure my door switch mounts are aligned & tightened properly.

From a similar manual:

1. Disconnect the power supply cord, and then remove outer case.

2. Open the door and block it open.

3. Discharge high voltage capacitor. If the door sensing switch, secondary interlock switch and monitor switch do not operate properly due to a misadjustment, the following adjustment should be made.

4. Loosen the two (2) screws holding latch hook to the oven cavity front flange.

5. With door closed, adjust latch hook by moving it back and forth, and up and down. In and out play of the door allowed by the upper and lower position of the latch hook should be less than 0.5mm. The vertical position of the latch hook should be adjusted so that the door sensing switch and secondary interlock switch are activated with the door closed. The horizontal position of the latch hook should be adjusted so that the plunger of the monitor switch is pressed with the door closed.

6. Secure the screws with washers firmly.

7. Check the operation of all switches. If each switch has not activated with the door closed, loosen screw and adjust the latch hook position.

After adjustment, check the following.

1. In and out play of door remains less than 0.5mm when in the
latched position. First check upper position of latch hook, pushing and pulling upper portion of door toward the oven face. Then check lower portion of the latch hook, pushing and pulling lower portion of the door toward the oven face. Both results (play in the door) should be less than 0.5mm.

2. The door sensing switch and secondary interlock switch interrupt the circuit before the door can be opened.

3. Monitor switch contacts close when door is opened.

4. Re-install outer case and check for microwave leakage around
door with an approved microwave survey meter. (Refer to Microwave Measurement Procedure.)

Siwtch door stuck open,


there is a switch on the front usually inside the back bottom latch it pushes on a switch in the back of it as you close the door.
you have to remove the top cover to get to it.
you can insert a plastic knife to test it. you should hear a click and light should turn off.
it may be jammed or open inside the switch .or wire is off. etc..
