To Next PageTo Next PageWhy is my Samsung CM1919 Microwave Oven completely dead?
If your Samsung Microwave Oven is completely dead, with no display or operation, even though the fuse is okay, it could be due to an open or loose lead wire harness, an open thermal cutout (Magnetron, cavity), an open low voltage transformer, or a defective Ass’y PCB. Check the fan motor when the thermal cutout is defective. Check Ass’y PCB when L.V.T is defective.
What does E1 error mean on a Samsung Microwave Oven?
If your Samsung Microwave Oven displays 'E1', it could be due to an improper input power frequency or a defective Ass’y Main P.C.B. Check if the power frequency is 50Hz. Replace the Ass’y Main P.C.B or MICOM.
How to fix uneven cooking in Samsung CM1919?
If your Samsung Microwave Oven is cooking food unevenly, it is due to the uneven intensity of microwave distribution, which is a characteristic of the appliance. Wrap thinner parts of the food with aluminum foil. Use plastic wrap or cover with a lid. Stir once or twice while cooking foods such as soup, cocoa, or milk.
What does E5 error mean on Samsung Microwave Oven?
If your Samsung Microwave Oven displays 'E5' (CM1929/1 629/1329), it indicates a Memory IC (EEPROM IC) failure or a MICOM failure. Check the Memory (IC3) and replace if defective. Replace Ass’y Main P.C.B or MICOM.
Why did the lamp go off in my Samsung CM1919?
If your Samsung Microwave Oven lamp goes off, it could be due to a loose lead wire or open lamp filament, misadjustment of the latch switch, or a defective primary latch switch. Tighten the lamp lead wire or replace it with a new lamp.
What does E41 error mean on a Samsung CM1919 Microwave Oven?
If your Samsung Microwave Oven displays error code E41, it could be due to a Main Relay (RY1) or Power Relay (RY2) failure, loose lead wires of relay, Primary or Monitor S/W failure, loose lead wires of Primary or Monitor S/W, or H.V.Trans input power sensing circuitry failure. Check the Main Relay (RY1), Power Relay (RY2) Primary S/W and Monitor S/W and replace if defective. Check if lead wires are loosened and connect firmly if loose. Check the circuitry and replace if defective.
What does E42 error mean on a Samsung Microwave Oven?
If your Samsung Microwave Oven displays error code E42, it could be due to a Power Relay (RY5) failure, loose lead wires of Power Relay (RY5), a Primary or Monitor S/W failure, loose lead wires of Primary or Monitor S/W, a blown fuse (10A) on the neutral area of the Assy Noise Filter, or a H.V.Trans input power sensing circuit failure. Check the Power Relay2, Primary S/W, Monitor S/W or Fuse and replace if defective. Also, check if lead wires are loosened and repair as necessary. Check the circuitry.
What to do if my Samsung Microwave Oven doesn't operate and returns to plugged in mode?
If your Samsung Microwave Oven does not operate and returns to the plugged-in mode, it is likely due to a defective Ass’y PCB. Replace the PCB main.
Why is my Samsung CM1919 sparking?
If your Samsung Microwave Oven is sparking, it is likely due to metallic ware or cooking dishes touching the oven wall, or ceramic ware trimmed with gold or silver powder. Ensure you are using proper cookware and avoid any items with metallic trimming.
Why Samsung CM1919 Microwave Oven 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 defective circuitry in the Start function of the Main P.C.B Ass’y or loose lead wires. Check the circuitry of the Start function of the Main P.C.B Ass’y and replace it if defective. Adjust or repair any loose wires.
