With no heat and louder noise, chances are you have a shorted high voltage rectifier diode or bad magnetron.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Sanyo Microwave/Combi/Grill 900W em-g 47535 on front. Timer works but does not heat up code 1S on display. Any ideas


It hardly matters what code is showing because clearly the appliance is receiving power (timer works) and the internal workings of a microwave oven are potentially very dangerous and only competent people should open them up and fiddle around inside.

Sorry but the fact you need to ask shows you aren't a person competent enough to risk your neck inside a microwave. If it is a basic oven out of warranty it would be cheaper to replace it, if it is under warranty send it back and if it is a premium model it could be worth taking to the repair shop for a repair estimate.

Exterior of oven , top and both sides gets very hot to touch, when cooking +- 10 minutes or more the last couple of days; no Error ( E41/42/45 or 47 are being displayed. Fan is normal, functions: OK


There could be food or oil buildup around the door frame which will absorb some of the radiant and microwave energy whilst cooking. Give it all a good clean and see if that helps. If everything else is working properly, it may be a problem with the cooling fan. Microwave ovens have a "stirrer fan" inside the roof or rear of the cooking area to disperse the microwaves and some convection / microwave ovens also have a cooling fan which assists in dissipating heat within the cabinet.

Not heating


Hello


Power Supply

Check whether there is a proper power supply. Look to see whether the cord is connected to a grounded 3-prong outlet and the cord is fully plugged in. If the electrical system is built-in and no power cord is visible, replace or reset the household fuse or circuit breaker.

Microwave Functions

Some basic microwave operational steps may affect whether the microwave is heating. Open and close the microwave door, as the unit will not function with the door open, and push "Stop/Clear" to cancel any previous settings, such as the timer, which do not heat the microwave oven.

Setting the Microwave

Once the power to the microwave has been reset, or verified as working, and the microwave is ready to run, select a new cook cycle and press "Start" to see if the microwave begins to run and cook food as expected. Allow the food to cook for the alloted time and then open the microwave door and check to see if the food has cooked or heated. Choose a longer cooking time and restart the microwave if food is heating but is cooking slowly.

Repair

If all efforts to troubleshoot the function and power to the microwave still do not get the appliance heating food as expected, there may be a repair issue that needs to be addressed. Contact professional technician for advice.

We have had this microwave for 7 years. Not had any problems until about six months ago when the volume went way down when you push the buttons and timer, but still heated. Then all of a suddon it does...


Remove the cabinet ... check the door safety interlock switches for proper operation. Most of the time, no heat problems can be traced to the oven thinking the door is open. These switches tell the oven if it is open or closed. If they are faulty ... well ... the oven thinks the door is open and will not turn on the heat.

Make sense?

Thanks for your question today.

Only display operative.


If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.If turntable is not running check also the door switch.

The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.
