What to do if Samsung Microwave Oven does not accept key input?
If your Samsung Microwave Oven isn't accepting key inputs, consider the following: * Ensure the key input is in the correct sequence. * Check for open or loose connections between the membrane keypad and the Ass'y PCB. * Inspect the membrane panel for shorts or opens. * A defective Ass'y PCB could be the cause. Replace PCB main.
Why Samsung Microwave Oven does not operate and return to the plugged in mode?
If your Samsung Microwave Oven isn't operating and returns to the plugged-in mode, the Ass'y PCB might be defective. Replace PCB main.
How to fix the turntable motor that does not rotate in Samsung Microwave Oven?
If the turntable motor in your Samsung Microwave Oven isn't rotating, here are a couple of things to check: 1. Inspect the turntable motor wiring for any opens or looseness. 2. The turntable motor itself might be defective. Replace turntable motor.
What to do if Samsung MR1032UBC can program but timer does not start?
If your Samsung Microwave Oven can be programmed, but the timer doesn't start, it could be due to: 1. Open or loose wiring of the latch switch. 2. Off-alignment of the latch switch. 3. A defective latch switch. Adjust the door and interlock switches.
Why is my Samsung MR1032UBC making a loud buzzing noise?
If your Samsung Microwave Oven is making a loud buzzing noise, here's what you can check: * Tighten the screws on the fan motor. * Tighten the screws on the H.V. Transformer. * Replace the H.V. Diode.
Why is my Samsung Microwave Oven taking longer to cook food?
If your Samsung Microwave Oven isn't heating food properly and takes longer to cook, there could be a few reasons: 1. Check if the power source voltage has decreased. 2. Inspect the magnetron filament circuit for any loose wiring, which can cause intermittent oscillation. 3. The magnetron might be aging. Consult an electrician.
Why does my Samsung Microwave Oven stop during cooking?
If your Samsung Microwave Oven stops operating during cooking, here are a few things to check: 1. Inspect the latch switch wiring for any looseness or breaks. Adjust the door and latch switches. 2. The thermal cutout (on the Magnetron) might be in operation.
What to do if Samsung MR1032UBC has no display and the fuse is blown?
If your Samsung Microwave Oven has no display and no operation at all, and the fuse is blown, here are some potential causes: 1. A shorted lead wire harness. 2. A defective latch switch. Check the adjustment of the latch switch and power relay. 3. A shorted HV Capacitor. 4. A shorted HV Transformer.
Why Samsung MR1032UBC Microwave Oven is dead, with no display?
If your Samsung Microwave Oven has no display and no operation at all, even though the fuse is okay, it could be due to: 1. An open or loose lead wire harness. 2. An open thermal cutout (Magnetron). Check the fan motor when the thermal cutout is defective. 3. An open low voltage transformer. 4. A defective Ass'y PCB. Check Ass'y PCB when LVT is defective.
Why is my Samsung Microwave Oven sparking?
If your Samsung Microwave Oven is sparking, it's likely due to: 1. Metallic ware or cooking dishes touching the oven wall. 2. Ceramic ware trimmed with gold or silver powder. Do not use any type of cookware with metallic trimming.
