I have this Sanyo microwave oven which produces no heat. Controls all
work; fan works, etc. No fuses blown (that I can find).
What can I check, please?
It's model EM-G471EUK, microwave and grill.
Thanks.
This can be from no high voltage, the magnetron may have failed, the
magnetron may not be activating for some reason.
Microwave ovens are very dangerous to work on, if you are not properly
trained and equipped. The high voltages and high currents used can be
lethal. When working on these, if the proper care is not taken if specific
parts are replaced, there is a possibility of strong RF radiation leakage.
After critical parts replacements are performed the tech is supposed to take
readings for leakage during the test operation.
It is strongly recommended that you get the oven properly serviced.

Everything works as it should. Low power settings cycle as you described,Can you hear the hum of the power transformer? Try setting it to defrost
with a cup of water in it, unless it's one of the newer inverter powered
units you should be able to hear the transformer cycle on and off.

I have already checked the switches on the door. Both are mechanically andYou may want to consider your options. You may not be able to source
replacement parts for your microwave, especially a critical part like a
magnetron. Replacing the oven with a new one may be a better way to
go. If
the problem was with something like the mains interlock switches, then
it would
be feasible to replace the switches and continue using the oven as the

It could be the magnetron, which is the device that emits the radio waves used
to cook the food, or more precisely, excite water particles causing those
particles to create heat from movement friction within the food (no bull!)

Mains capacitor? What mains capacitor? Do you mean the high voltageThat's what I did with my old 1981 Panasonic Dimension3 oven when the interlock
switches wore out. I replaced the mains interlock switches on both the top and
bottom door latch holders as well as replacing the plugs on the wiring harness
that connected to the switches as they had burned from heat caused by
resistance in the bad switches.
The safety warnings cannot be overemphasized as microwave ovens are one of the
most hazardous electronic pieces to work on. Improper service can cause
exposure to hazardous levels of microwave frequency radiation. Another hazard
is the mains capacitor, which is capable of storing a charge that is lethal.
Yes, In fact, with a no heat situation, the HV capacitor may end up beingEven if the capacitor is configured to self-discharge (a resistor connected
between the leads of the capacitor is a typical configuration), you must always
assume the capacitor is live until you discharge it to a proper ground. -

I have already checked the switches on the door. Both are mechanically and
electrically working - and they are standard V3 types.
No problem with the mirror sites, thanks.http://repairfaq.ece.drexel.edu/sam/micfaq.htm
