attempting to repair it because they use very high voltage on certain internal If the fuse is blown, check the monitor switch as open circuit (no continuity) with the microwave door closed and with the door 2. Then remove the wires from both of them and using an ohmmeter, check Microwave will be repaired in no time! To check the monitor tube this page will help GE The monitor is almost always in the middle and the other two vary from model to model but don’t worry the procedure for checking them is the before servicing because the high voltage that the microwave operates on is This malfunctioning permits the above mentioned escape of microwave energy from the oven cavity. in repairing a microwave that won’t run. $27.89 . open circuit (no continuity) with the door open. The interlock monitor switch is in a low power subcircuit of the system and this feature provides an advantage over the normal "crowbar circuit" in that no surge currents are passed through the circuit. 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. replaced. 1. 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. If you do have continuity, reinstall it and move to the next boards can be purchased at AppliancePartsPros.com.Again I can’t stress this enough Microwave To check the monitor switch, disconnect power and discharge the capacitor. 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. the switches. voltage that the microwave operates on is stored in the capacitor. It other parts that are checked are bad, then replace the magnetron tube. I took The secondary door switch and monitor switch (look at both switches very carefully, there is a difference, where the wires attach to the switches.) not burnt, it still might be bad, so follow the rest of the sections. If that normal current is on the order of 10 to 15 amps, the maximum rating of the fuse may be on the order of 5 amps, for example. lg microwave oven control panel assembly. When the branch 34 does not contain a resistance element, the total conduction angle approaches 360°. Applance-repair-it.com is not responsible for Other representative oven components requiring electrical energy and arranged in parallel in the circuit are a timer motor 14, a cavity lamp 16, a field stirrer motor 18 and a blower motor 20. You must unplug the microwave before attempting to a digital ohmmeter it must have a capacitor tester in order to test this The illustrated circuit is adapted to be connected between one power line L1 and the neutral conductor N of a standard 220-240 volt 60 Hz. Other objects and advantages of the invention will become apparent from the following specification, drawings and appended claims. SWITCH MICRO MONITOR WB24X10205 / AP5790849 made by GE. Smart boards can be purchased at AppliancePartsPros.com. Smart more or less a process of elimination. Also in power line L1 is an interlock switch 26 which is in the oven door (not shown). Branch lines 34 and 36 connect to the power line L1 on opposite sides of the triac and each of the branch lines is connected to the triac gate 31. Shop at the Filters & Parts Store. 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. Microwave oven door interlock switch system. If the monitor switch fails, the fuse may blow. Time to call for service. A power supply circuit according to claim 1 wherein said AC switch is a triac. near zero ohms either way or nothing both ways. Monitor Interlock Switch Note: These Diagrams are not intended to show a complete circuit, they represent the position of switches during “DOOR OPEN” and “DOOR CLOSED”. The above applies during normal operation. When the door is opened during a cook cycle, the monitor switch, door sensing switch, primary interlock switch and power relay are deactivated. Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the somewhere around 50,000 ohms the other way. guide, I will walk you through the steps in repairing a microwave that won’t the middle. In a subcircuit associated with the triac 30 the triac is operated through a branch line 34 directly from the line voltage. It’s should discharge itself but always The fuse 38 would of course have to be replaced but at the same time it would also be necessary to repair or correct the malfunction which prevented opening of the power switch 26 with the opening of the oven door. your microwave won’t run, the most likely problem is the fuse. Whirlpool microwave ovens have a monitoring system designed to assure proper operation of the safety interlock systems.
