This is usually an indication that the magnetron has gone bad, or something in the high voltage network controls the magnetron. Any one of the following components could be at fault: 1. Magnetron 2. High Voltage Transformer 3. High Voltage Diode 4. Magnetron Thermal Cut-out 5. High Voltage Capacitor 6. Interconnecting wiring I do not advocate taking any voltage measurements inside the High Voltage section of a microwave since the voltages can be as much as 14,000 volts or higher. If you are savvy enough to attempt yourself, WITH THE MICROWAVE UNPLUGGED, you will need to disassemble the unit to get to the high voltage section and take resistance readings. The magnetron or diode are likely suspects. If the magnetron or the transformer are bad, the repair costs can meet or exceed the price of the oven. Let me know if you need further assistance.

Samsung microwave oven Model # SMH9151S. Turntable not turning fan inside (not the exhaust fan) is not working either.

It may be a failed relay on the control board, which I repair affordably.

See my profile picture if you need more help.

Sharp combo microwave: Turntable wont stop unless I leave the door ajar. Light stays on too while turntable is going. Everything else works fine - it just doesn't know when to shut up! :)

It's a door switch that's bad. Probably the secondary interlock switch. You need an ohm meter to verify switch not 'making' electrically. Usually the only thing that causes this switch to fail is from opening the door when the microwave is cooking, secondly, by cooking at very extended lengths of time.

Not heating

Please post a new help request here on FixYa and include the full model number from the tag in the cooking cavity or elsewhere on the microwave, such as the door frame, controller frame, etc. and please answer the questions below.
When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here

Frigidaire model cfmv156fmc allows programming, lights work but when hitting go wont turn on yet timer is counting down.

If the inside light comes on when you try to cook, but the turntable and internal cooling fan do NOT, then that's a bad bottom door switch or that switch's mount.

See this helpful text file.

If the inside light, turntable, and internal cooling fan DO all come on when you try to cook, but it does not cook, then you have a bad relay or connection on the control circuit board, which we can repair for $39.95. Details here.

We have the service manual and have uploaded it to our site here to help you.

Lights, fan,etc work but turntable does not rotate and oven does not cook.

Sounds like the table motor may have an issue. You might want to consult you local repair depot for an estimate. Sometimes the repairs are more than the appliance...beware!

My panansonic microwave NN-T573SBBPQ works for 2-3 seconds then turns itself off! the lights all work, turntable goes around, fan works, time is on.

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.

In most cases, this is a problem with the inverter or a bad magnetron.

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

I would recommend that you contact your nearest Panasonic-authorized servicer.

Turntable goes around when the door is open and the microwave is off.

Do not run the microwave with the door open. You will be cooked. Sooner or later, if there are enough microwave ovens, (and there are), everything that can go wrong with them will, eventually. There are several interlocking safety systems built into every microwave so that they won't work with the door open. Yours may have failed. I've never come across one, but that doesn't mean it can't happen.
It may only have a fault making the fan and turntable operate, which can sound like it's working with the door open. Either way, get it checked or get a new one.
This assumes that the microwave isn't actually supposed to do what it is doing under normal conditions or current programming. Refer to manual/instructions if
