Kenmore spacemaster microwave Auto recipe 300

George,
Kenmore is a Sears brand and I have included a link to their parts website and the bulb. I hope it is the one you are looking for. Lamp Part Number 10529 GUARANTEED FIT from Sears PartsDirect

Check those 3 micro switches in the door latch assembly. A bad microswitch can blow the main fuse. This usually ruins the microswitch.

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

whether the difference in the voltage supply affect the functioning of microwave

This applies to several models:

"f9 model 721.63764300
Kenmore Elite 36 " over tne counter microwave is supplied by LG made by Gold Star, made in China. It's main problem is the high voltage inverter board supplyed by Sears Parts. If you get a F-9 code on your microwave display screen and the micro quits it's probably this board. Reset the machine by pulling the power plug and waiting an hour. If it is the high voltage board is at fault it will probably fail after 45 seconds of start up. This part is really hard to get at but is less than $100. A qualified technician should be able to remove and repair this item in less than hour. Some techs will quote you $300 labor, don't buy it, it should cost a $100 or less. No need to buy another microwave."

You can usually find exploded views and order parts by entering your model number at the Sears parts site.

BUT once you have the part number from the Sears site, you can often get the parts cheaper here.

No if the fan works the fuse is fine; unplug and, check the bulb socket

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

Here are some links you or someone you know can use (in order given) for high voltage section test help, but read the safety warnings first:

(if it is NOT shorted or burned looking, it's probably fine)

(continuity can be good even though mag is bad!)

i just checked my R-3A36 manual to find out the wattage. it's 800 watts. i make pralines in my microwave. i am always asked for the recipe. so i needed to be able to tell people the wattage of my oven so they can adjust the recipe to their oven.
garry, metairie,la.

Thanks, just had the same issue. Can't find the manual and can't remember back that far! Thanks for posting the solution.
