This is a microwave, correct?
I suspect the door lock interface switch(es) are burned out. Unplug it, be mindful of the 25,000 volts in the silver thing. Check the micro switches (look where the door closes on the top right side, probably) two positions, normally open or normally closed. check them for proper operation.
Micro switches are the most common of microwave failures because most of us open the door while the machine is running causing arc at the switch and burning up the little contacts.

Most likely the hi volt energy components. Usually the hi volt diode or hi volt capacitor. There is hi energy stores here so be careful or do not attempt it. A person skilled in electronics, tv repair, or microwaves can handle it . It is usually worth repairing. The other parts that could be the problem are the magnatron or the hi volt transformer; if so, you might think twice before repair (the price will be higher).Goodluck, Macgivor

If everything works, but the microwave oven does not heat, this is commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven. This is what produces the RF energy that heats your food.
Here's what you need to determine whether or not its worth fixing:
1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
2. You will need to ensure the oven is UNPLUGGED before servicing anything inside the cabinet. You will need to remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com
If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
3, The magnetron replacement part number for the model you have listed is WB27X10305. The average cost is about $80. NOTE: I found the part listed for the best price at appliancepartspros.com at a cost of $76.
You need to decide whether or not $80 and the amount of labor involved is worth the effort as opposed to replacing the entire oven at a higher cost and less labor (other than the installation). Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble.
If you have any questions, please post back and let me know. I hope you find this information helpful
CAUTION: DO NOT operate a microwave oven with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts.
