Re: Changing Power level on Westinghouse microwave

If it won't cook at the lower power level then it probably has a stuck relay on the control panel circuit board.

If it were cooking at a low power level, it would be on full power for several seconds, then when the relay opens to turn off cooking, the light gets a bit brighter, and the sound is a bit less.

Then after a few seconds you would hear the relay click on, and a little more buzzing when the magnetron energizes.

Please write back with your brand and model number if you need further help.

Frigidaire Pro micro power level options do not work. Can this be repaired?

Good Morning Charles Caulkins, thanks for your post!

From my understanding your Frigidaire microwave is not allowing you to change your power level. I would recommend performing a reset and you can do that by disconnecting power from your microwave for ten minutes. If that does not help to resolve your issue I would suggest having a professional come out to provide a proper diagnosis. This will help to avoid any unnecessary part purchases. Hope this information is helpful to some degree. -Matt

A model number would help, but if it's really old, information may not be available.
If this is a simple mechanical lock which you're supposed to be able to lock and unlock by hand, maybe it's rusted. A penetrating oil like PB Blaster may help.
If it's a relay-drive lock that's controlled by the circuit board, then it may need board repair, etc.

My GE Microwave Oven won't let me change the Power Level. It is on 10 and takes forever to warm up food. It is supposed to default to Hi but doesn't. I followed the directions for changing the...

There is a solid state switching device called a triac "electronic voltage controller" that has malfunctioned, it controls the power level settings when making power selection, It will need to be replaced to correct the problem. This repair should be done by a qualified technician because dangerous high voltages are present.

I have never used the power feature and now I need to and cant find manual. How does the power feature work. I need to operate the microwave on medium power for one minute.

1 Use the number buttons to set a cooking
time. You can set a time from one second to
99 minutes, 99 seconds. To set a time over
one minute, enter the seconds too. For
example, to set 20 minutes, enter 2, 0, 0, 0 .
2 If you want to set the power level to
something other than High, press the Power
Level button, then use the number buttons
to enter a power level.
Power Levels:
Level Cooking PL
3 Defrost 30
4Medium Low40
6 Simmer 60
7 Medium High 70
8 Reheat 80
9 Saute 90
10 High Hi

Hope that helps.

Reduced power

I have found the main cause for this problem is a magnatron assemble that is becoming faulty. I advise changing the Magnatron. Good Luck.

3. Press number keys to set the desired cooking time.
4. Press the START/+30SEC. button to start cooking;

Instruction Manual for Sharp Microwave Oven

I can explain that. You enter the power level you want from 0 to high(10) the number corresponds to a percentage of time the cook cycle is ON. 5 being 50%, for each minute of cook time programmed the magnatron will be on 30 seconds and off 30 seconds. You can program anything from 10% to 90% in place of the high or "always on" setting. Eric

Power level 10 would be the default - what it is set to unless you manually set it lower.

Power level 0 (zero) is often the setting to use if you just want to use the oven as a timer.

Many Emerson microwave owner's manuals are available for free download here.

Would that answer your inquiry?

If not, please write back with more details.

Sanyo EM-P740w

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?
