Ge over the range microwaves have this problem . for some reason the plastic sort of melts but not realy (please check hinge for wear and adjust if ness ) , it just gets out of shape from the heat and this makes the switches not work properly . most likely the micro is too close to the stovetop . see your manual about that and you can buy the slideing plastic parts where the switches are , its just big $$$$ if the micro is to close it will happen again GOOD LUCK

You will need to remove microwave to access casing, remove casing and check door micro-switch. The switch activator will need adjusting to enable door interlock to activate.

Why does Panasonic nn-sn651 usually work; but sometimes, turntable won't start ?


This is an inverter model so there is no diode or hv capacitor.
You must adt. the door latch switch assembly to make sure that the door hooks make contact with the switches. Common problem is that the assembly is bent and must be perpendicular to the door.If it is bent the switch will not make contact with the door hooks.
Place a dab of lithium grease on the tip of the door hooks to ease closing the door. This is the cause of the bent switch assembly!

I replaced a cracked door on my Whirlpool microwave MH1150XMQ2 and now it wont work. The light stays on and I can enter info into the display, but the unit wont turn on.


The door is not adjusted correctly.
The micro switches in the cabinet are not making contact.
Radjust the door hinge until the switches are made correctly by the latches on the door.

Door latch and Screen


This is because of the broken latch. There are switches inside the oven that are operated by the door latches to make sure you're not trying to use the oven with the door open. With the new door, your oven should be back to normal.

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.

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.)

MY PANASONIC MICROWAVE OVEN HAS POWDER BUT IT DOES NOT HEAT.


I'm assuming the clock is on and controls appear to work, but won't start cooking. Quite often the latch on the door can slip out of place, so the safety interlocks do not clear even with the door closed. The latch can be accessed by removing the cover of the microwave, and should be easily visible. The latch assembly can be adjusted by loosening the screws and pushing the unit upwards. Re-tighten screws on new position. A very small adjustment is usually enough. Do not undertake repair work if you are not up to it.:::Spiceweasel.au
