Question

4. What is the function of the thermo cut out in microwave oven?
a) Provides a current path to the stirrer motor
b) Completes the circuit to the coil of the cook relay
S) Prevent damage to magnetron at overheat condition
d) It provides the holding circuit energizes the coil
M​

Answer 1

Answer:

The stirrer blades distribute the microwave energy to promote even cooking inside the microwave cavity. They prevent hot spots.

The blades normally need to be replaced by a service technician. Microwave ovens are inherently dangerous to service. Internal capacitors can retain a lethal electrical charge even when the microwave is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal repair. These are the reasons that a technician should complete any internal component repair on a microwave.

Answer 2

Answer:

Thus option C is correct

Microwave ovens use one or more thermal cut-outs, sometimes called thermal fuses, to protect the oven from overheating. They are located inside of the cabinet, often near the oven cavity or the magnetron. If the thermal cut- out fails, power is interrupted to the controls or to the control outputs.
