It could be the fan motor, a component on the circuit board that drives the fan (triac) , the magnetron, high voltage transformer, etc.

It will need to be diagnosed. Smoke is always a bad sign, but not necessarily expensive for a do-it-yourselfer.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

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.

New sanyo microwave, steam or smoke coming out when cooking from 1 minute


Steam is OK as it means whatever is in there is boiling furiously, it may need turning off at that point!
Smoke though means it has gone too far. Check the cooking times used and the recommended cooking times on the packet along with the adjustment for the power of your oven.

Does the exhaunst fan turn on automatically when we cook or warm food items in our Samsung Microwave -- SMH 9187W?


Some interesting reading on page 8 of the owner's manual:

"Boilovers cause smoking and greasy spillovers that may ignite and spread if the vent fan is operating.To minimize automatic fan operation, use adequate sized cookware and use high heat on surface units only when necessary."

And on page 20:

"If the temperature becomes too hot around the microwave oven, the fan in the vent hood will automatically turn on at the LEVEL 2 setting to cool the oven. The fan will automatically turn off when the oven has cooled down sufficiently. This is an automated process and cannot be turned off. The fan may stay on for 30 minutes or more after the cooktop and microwave controls are turned off. The Vent Fan will only operate in 1~4 levels modes while the microwave is working."

"Using the Vent delay off button
1. Press the Delay Off button once to turn the fan off after 1 minute.
2. Press the Delay Off button twice to turn the fan off after 3 minutes.
3. Press the Delay Off button three times to turn the fan off after 5 minutes.
4. Press the Delay Off button fiour times to turn the fan off after 10 minutes.
5. Press the Delay Off button five times to turn the fan off after 30 minutes."

If for some reason you don't have your owner's manual, you can still download it free here.

My fan works on my microwave by it does not draw suction


Actually, the fan in the microwave is only there to cool down the magnetron which cooks the food. It gets very hot over a period of time and the maintains constant temperature across it. Suggest you use an extractor to remove fumes.

Microwave still continues after cooking time is ended


It is the fan. Im guessing it only happens on combination cook and not when you are only using the microwave setting. It happens because the oven is hot and it helps to cool it quicker. It is normal. The microwaves are not working and neither is the oven-just the fan.

Does not cook - time counts down extremely fast


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 about 5 minutes.

Then let us know if the hard reset does not fix it.
and please reply back with your brand and model number so we can help you.

Turn on, but I don't har fan and it startd smoking.


I would suspect a problem with the high-voltage inverter.

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.
