It no longer runs the full time cutting out after 30secs which ever programme

MICROWAVE PROGRAMMABLE AUTO NITE LIGHT Some over-the-range microwaves had a programmable Auto Nite Light feature, which will turn the surface lights on low on at a specific time. The Auto Nite Light feature can be set to turn on and off at any time desired.
Follow the directions below for set-up:

1. Press the AUTO NITE LIGHT pad.
2. Enter the time the light is to turn on. Select A.M. or P.M.
3. Press the AUTO NITE LIGHT pad again and enter the time the light is to turn off. Select A.M. or P.M.
4. Press the AUTO NITE LIGHT pad once again.
5. The word NITE will show in the control window as a reminder that the feature is set. The settings can be reviewed by pressing AUTO NITE LIGHT.

To erase the settings and turn off the automatic feature:

• Press the AUTO NITE LIGHT pad, then press the ZERO pad.
• The NITE indicator will no longer be lit.

Based on a 1200 watt microwave. Increase time for less wattage devices.
Place in a large casserole dish with lid and cover with water.
Heat on High (full power) for 15 minutes then 15 to 20 minutes per 450g at Medium power.
Allow to stand before serving as always.

My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

Hi,

Here is a tip that I wrote that will give you some things to try that will helpyou get your Keurig coffee brewer workingagain.

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type. In this case it seems that the program controller board has errors specially if the oven heats and shuts off. remove the board, clean and reset.
If there is heating without any issues, you can use the microwave safely

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional and must not be attempted by the novice.
Hope that helps.

See if this describes what's happening:

• Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector

If so, see http://207.234.249.73/mwd/safety.txt , http://207.234.249.73/mwd/disassembly.txt and http://207.234.249.73/mwd/doorsw.txt

Otherwise, if the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

That may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

on the bottom of most units you can get to the turntable motor with some side cutters,cut the joins. pull the little flap off and there is your motor run a current through it to see if it turns(how much will say on the motor) if not turning there is your problem

Maybe bad fuse or fuse holder or both

Does this happen just at the full power microwave cook setting?

Have you tried defrosting and doe sit do it on this setting? Does it run any longer in defrost mode?
