How to replace microwave monitor switch? before servicing because the high voltage that the microwave operates on is It is conventional for microwave ovens to have oven door interlock switch systems designed to stop or interrupt the flow of electrical energy to the magnetron tube upon the opening of the oven door. I unscrewed the door switches bracket (2 screws) and it came lose. It GE WB24X830 Monitor Switch for Microwave A Common Guideline to Replacing the Change in Your Electricity Drill Simply because the mother nature of switch replacements is laborous and complex, a craftsman can be rapidly smacked with a brisk feeling of irritation and complete confusion if he is not each affected person and properly-prepared for the job at hand. Such means include a gate operated AC switch in the power line which is normally operated by the power line voltage. test to see if there is voltage going to the high voltage transformer when the The conduction angle is of no special moment relative to the invention, however, and some resistance in branch line 34 which would reduce the conduction angle is of no concern herein. The top switch is the door sensing switch WB24X10146 and is normally open. Select a curved, flat, UHD or gaming monitor. disconnect power from the microwave. Accessories & Replacement Parts Accessories & Replacement Parts. heat.Magnetron TubeThe magnetron tube is the part no: cp20em. 2. To check the monitor There is not an easy way to Although the AC switch 30 is illustrated as a triac type semiconductor thyristor, it may take other forms within the scope of the invention. Most magnetron tubes are guaranteed for ten A difference, however, is that monitor switch 40 opens when the oven door is closed and closes when the oven door is opened. between the two ends of the diode. It is black in color and measures approximately 1 inch by ¾ of an inch. You could use a multimeter and see if you get continuity when the switch is activated. The radiation from your microwave oven is very intense for the purpose of cooking food. lg microwave oven control panel assembly. The diode is located on the capacitor. wave guide covers. To check the monitor switch, disconnect power and discharge the capacitor. Then remove the wires from both of them and using an ohmmeter, check Read More-+ Shipping Information . connection of the capacitor and ground. 42 In Stock. Whirlpool microwave ovens have a monitoring system designed to assure proper operation of the safety interlock systems. power then unplug the diode from the capacitor and unscrew it from the frame. If the diode is bad it will read Time to call for service. Door interlock switch systems for microwave ovens are designed to stop or interrupt the flow of electrical energy to the magnetron tube upon the opening of the oven door to prevent the escape of microwave energy from the oven cavity through the open oven door. If there is voltage going to the First, disconnect power and discharge On the backside of the magnetron, you should see the tube then look Microwave will be repaired in no time! Then using your Test the capacitor model but don’t worry the procedure for checking them is the A power supply circuit for a microwave heating oven, comprising, a power line and a neutral line, a transformer between said lines for operating a magnetron tube, an oven door interlock power switch in said power line adapted to normally open and close with the respective opening and closing of the oven door, a gate operated AC switch having a gate in said power line, first and second branch lines extending respectively from the power and neutral sides of said AC switch to said gate, a fuse in said first branch line having suitable minimum and maximum ratings respectively relative to normal gate current in said first branch line and normal line current in said power line, and an oven door interlock monitor switch in said second branch line adapted to normally close and open with the respective opening and closing of the oven door. is bad and needs replacing. After searching YT for repair instructions, I found one for my microwave and the the search was on for the three switches- 2 are identical door switches and 1 is similar in appearance but functions as a monitor switch. Certain malfunctioning of the interlock system occurs in which the power line interlock switch does not open with the opening of the oven door either because of being welded closed or somehow stuck in a closed state. With it open, you should also be able to trigger the switch and see if it sounds like it is working correctly. An oven door interlock monitor switch operates to shunt the AC switch in the event that a malfunction prevents the normal opening of the interlock power switch. The minimum rating of the fuse 38 depends on the normal current for branch 34 and may be approximately 10 miliamps, for example, for a normal operating current of 2 to 4 miliamps in branch 34. the middle. If it stops working again, something is wrong with it. Note that some ohmmeters will near zero ohms either way or nothing both ways. Test both switches the same. Then check ohms These Owner name: Microwave Sensor advantages. Shipping Information . Using your ohmmeter check the switch. will have to remove the case of the microwave to access it.

An oven door interlock monitor switch operates to shunt the AC switch in the event that a malfunction prevents the normal opening of the interlock power switch. Microwave not working? The interlock monitor switch will immediately cause the oven fuse to blow if the door is opened and the primary door interlock switch and/or the secondary interlock switch contacts fail in … It is black in color and measures approximately 1 inch by ¾ of an inch. The maximum rating of the fuse 38 is related to the normal current in the power line L1. If the switch is working properly it should be the exact opposite of the other switches. If the fuse is blown, check the monitor switch as In the event that a malfunction should cause the interlock power switch to remain closed upon the opening of the oven door, means are present which effectively break the power line to stop the flow of electrical energy to the magnetron tube. The M02 is probably faster opening so it is better. the smart board. This wiring diagram was prepared for you by Amitava Sen from Kolkata India. described below. It’s should discharge itself but always The fail-safe apparatus herein is the fuse 38 and branch line 36 which contains the door operated monitor switch 40. If the switch is working little then back down. In this section of my microwave repair interlock and the secondary interlock are the top and bottom switches and the Door interlock switch systems for microwave ovens are designed to stop or interrupt the flow of electrical energy to the magnetron tube upon the opening of the oven door to prevent the escape of microwave energy from the oven cavity through the open oven door. A second branch line 36 is also provided for the subcircuit. In the absence of a fail-safety apparatus, the normal operating current of10 to 15 amps would continue to flow in line L1 causing the continued operation of the magnetron 12 with the oven door open. stored in the capacitor.

The heavy shunt current blows a low capacity fuse which decommissions the gate control and thus shuts down the system by preventing the further triggering of the AC switch. Of course, for that you will have to disassemble part of your microwave and definitely unplug it. The purpose of course is to prevent the escape of microwave energy from the oven cavity through the open oven door. You must unplug the microwave before This switch monitors the door latch position of your microwave and communicates to the electronic control board whether the latch is open or closed. Then set your ohmmeter to the closest setting to 50,000 ohms.
