EM-G4753 My EM-G4753 is suddenly not working all the system is ON but when i press start it just doesn't work. Please HELP......... I have a similar model (EM-P415) and problem. Only the timer starts counting down when I press the Start button - no heating, fan, or table rotation. Any ideas? Anyone know where to get a service manual?

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

First of all, thank you very much for choosing FIXYA today for your online technical support needs.


Here is a direct link to the ONLINE USER'S MANUAL for that model:

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 but if you are safety clued up, here's instruction.
Make sure the !!!!any capacitors are discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Yes. Follow the cooking instructions supplied.

The touch pad seems faulty, there may be moisture behing the first touch pad film, suggest replacing touch pad as it cannot be fixed, Phil

Sounds like a component failure in the microwave circuit.

It will be one or more of the following -

Fuse
Diode
Capacitor
Transformer
Magnetron

Reply back and I can help you more. These failures happens to new or old microwaves.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Otherwise, it sounds like your "defrost" key on the keypad may be shorting.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

Here are lock / unlock schemes for three recent Sanyo models:

- Press and hold Stop/Cancel for 3 seconds
- Press and hold Stop/Reset for 3 seconds or so
- Press Stop/Clear five times

Hopefully one of those will work.

If none of these work for you, contact Sanyo Service Customer Service.

I'm thinking that the circuit board has a problem. I doubt it will work but disconnect all the connectors on the board...with the power off and reconnect. It may clean off some goo. If not, use your method as long as it will work and then consider a new board.

It looks like you would enter the cooking time then press POWER 1 to 10 times. Once = 100%, twice = 90%, thrice = 80%, and so on, and "PL#" will appear in the display where "#" is the selected power level. On some models, twice = 80% and thrice = 60%, etc. and "80%", or "60%", etc., will appear in the display. Then press START. Did that do it?
