Why won't my Samsung CE118KFR accept key inputs?
If your Samsung Microwave Oven does not accept key input (program), it could be due to: * Key input not being in sequence. * Open or loose connection of the membrane keypad to the Ass'y PCB. * Shorted or open membrane panel. * Defective Ass'y PCB. Refer to the operation procedure and replace the PCB main.
Why does my Samsung CE118KFR program but the timer won't start?
If your Samsung Microwave Oven can be programmed, but the timer doesn't start, it may be due to open or loose wiring of the secondary interlock switch, off-alignment of the primary interlock, or a defective secondary interlock S/W. Adjust the door and interlock switches.
Why is the turntable in my Samsung Microwave Oven not rotating?
If the turntable motor in your Samsung Microwave Oven does not rotate, it could be due to open or loose wiring of the turntable motor, or a defective turntable motor. Check the wire of the turntable motor and replace the turntable motor if necessary.
Why is my Samsung Microwave Oven sparking?
Sparks in your Samsung Microwave Oven can occur if metallic ware or cooking dishes are touching the oven wall. Also, ceramic ware trimmed with gold or silver powder can cause sparks. Avoid using any type of cookware with metallic trimming.
Why is my Samsung Microwave Oven cooking slowly?
If your Samsung Microwave Oven takes longer to cook food, it could be due to a decrease in power source voltage, open or loose wiring of the magnetron filament circuit (leading to intermittent oscillation), or the aging of the magnetron. It's recommended to consult an electrician to check the power source.
Why is my Samsung CE118KFR making a loud buzzing noise?
A loud buzzing noise from your Samsung Microwave Oven can be caused by loose fan and fan motor screws, loose screws on the H.V.Transformer, or a shorted H.V.Diode. Try tightening the screws of the fan motor and the H.V.Transformer. If the noise persists, replace the H.V.Diode.
What to do if my Samsung Microwave Oven is dead but the fuse is OK?
If your Samsung Microwave Oven is completely dead (no display, no operation) but the fuse is okay, the cause could be: * An open or loose lead wire harness. * An open thermal cutout (Magnetron). * An open low voltage transformer. * A defective Ass'y PCB. Check the fan motor if the thermal cutout is defective. Check the Ass'y PCB if the LVT is defective.
What to do if my Samsung CE118KFR has no display and the fuse is blown?
If your Samsung Microwave Oven has no display and no operation, and the fuse is blown, it could be due to: * A shorted lead wire harness. * A defective primary latch switch. * A defective monitor switch. * A shorted HV Capacitor. * A shorted HV Transformer. Check the adjustment of the primary, interlock monitor, and door sensing switch.
Why does my Samsung CE118KFR stop during cooking?
If your Samsung Microwave Oven stops operating during cooking, it could be due to open or loose wiring of the primary interlock switch or the operation of the thermal cutout (Magnetron). Adjust the door and latch switches.
How to fix uneven cooking in Samsung CE118KFR?
Uneven cooking in your Samsung Microwave Oven can be due to the uneven intensity of microwaves. To mitigate this, wrap thinner parts of the food with aluminum foil, use plastic wrap or cover with a lid, and stir once or twice while cooking foods such as soup, cocoa, or milk.
